Talk given at Crabb Lab Meeting, City University, London UK – Wed 23 August 2017
Medical Imaging: 8 Opportunities for technology entrepreneurs and investorsHealthstartup
There is tremendous opportunity currently to conduct advanced analysis of imaging data for diagnostic and treatment planning purposes, to combine imaging data from various sources and to share images for better medical collaboration. While medical imaging used to be the exclusive domain of large multinational medical devices companies, startups are entering the fray with software-based solutions and clever use of open-source or consumer-based technologies.
In this talk I'll discuss work in biomedical image and volume segmentation and classification, as well as outcome prediction modeling from insurance claims data that I've pursued at LifeOmic here in the Triangle. In the former case datasets include radiological image volumes, retinal fundus images, and cell images created with fluorescent microscopy. The latter includes MIMIC-III data represented as FHIR objects. I'll discuss the relative challenges and advantages of doing ML locally vs. on a cloud-based platform.
This presentation summarizes our research on 40 companies from around the world that are leveraging Artificial Intelligence to improve the Healthcare Industry. They are all well-funded, have highly qualified CEOs & Boards, and are poised to achieve their product development milestones.
The I-Square Ventures proprietary rating algorithm indicates that almost all of these companies will receive more funding, and/or be acquired by larger companies.
In this presentation I share the ideas regarding Radiology and AI relation to each other . Its helps to explore more about radiology . Its key advaantage is that u find a detailed knowledge of Radio Imaging and AI at the same platform . If u want to know about the healthcare and research centers where AI is used you also find the collabration among various AI TECHNOLOGY MANUFACTURERS and RESEARCH CENTERS . If you are doing graduation in AI or RADIOLOGY field , it well define your stream . It enhance the workfield arena for radigraphers and how they will increase their job profiles and clearly differntiate them between Robots and AI because most of our assests thought AI in healthcare leads to robotic work but they are totally wrong in this , they need to understand that AI is just going to decrease the work pressure on them . This will not going to take their jobs and our radio imaging machines are only operated by our medical proffesssionalists i.e. our Radiotechnician . It will reduce the waiting time for patients and it increase the job satisfaction for us. As a Radio Imaging student , I try to clear all the doubts regarding the job misconceptiopns in our mind. We must be prgressive , truthful and honest while our job responsibility. AI will help in faster Image Analysis , it helps in Diagnostic accuracy, it also helps in early detection of disease , as it will pre analysize the data from various modalities and make a 3D view of the image form . It leads to increase the patients trust on our healthcaere providers . It helps in unnecessary excessive radiation to the patients , leads to decrease in the risk of radiation related diseases , like skin erethema , skin cancer and skin infections . Yeah.. you also find some challenges regarding smart radiology but by doing proper cincern in your imaging field you will going to solve all the errors in it . We must try to organize short confrence in which we share our views and plans for future innovations and this presentation is small effort towards it. It will also control the quality of your images . This presentation will help you differntiate between the TELEMEDICINE and PACS . I also share the requireds tools and techniques which are using in radiological field . Some of them are - machine learning, deep learning, natural language processing, computer aided detection, image segmentation, 3D- Imaging analysis, automated repoting , radiomics, generative adversial networks . It will show you how AI effects life of Radiographers and Technicians , by stating : efficiency and productivity, workload management , skill enhancement, career evolution, job satisfaction, and patients care, quality assurance. Here , I also share some case studies where AI ia implemented in Radiology, it includes Cleveland Clinic collabration with Zebra Medical Vision , Stanford Medicine use of ARTERYS and UNIVERSITY OF CALIFORNIA , SAN FRANCISCO [ UCSF] and TEMPU . Whereas some challenges in adopting AI in Radiology.

Presentation of the EUSOMII/ESOI annual meeting in Valencia, Oct. 2016, about the impact of new communication tools on the communication between radiologists, clinicians and patients
In this thesis the impact of digitisation on radiology is analysed based upon diverse initiatives and research projects that were conducted in the period between the early days and now. Various topics such as web-based sharing of radiological images, teleradiology, digital communication and advanced processing of medical data, are discussed. Based on these findings the author formulates his vision and advises about the future role of the radiologist.
In the dissertation The impact of information technology on radiology services the author describes the most important changes that took place in the field of information technology since the end of past century, and their impact on radiology.
A real revolution has been provoked in radiology by the complete digitisation of medical imaging and the deep integration of Internet in both society and healthcare. Digital archiving, processing and distribution of radiological images, as well as the development of various types of teleradiology, are an important part of this change.
Radiology is facing many new challenges and opportunities due to the on-going exchangeability, integration and automated analysis of medical data and images. Other major trends such as the increasing personalisation of medicine and growing engagement of patients in their healthcare process are also significantly influencing this turnaround in radiology.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
New Drug Discovery and Development .....NEHA GUPTA
The "New Drug Discovery and Development" process involves the identification, design, testing, and manufacturing of novel pharmaceutical compounds with the aim of introducing new and improved treatments for various medical conditions. This comprehensive endeavor encompasses various stages, including target identification, preclinical studies, clinical trials, regulatory approval, and post-market surveillance. It involves multidisciplinary collaboration among scientists, researchers, clinicians, regulatory experts, and pharmaceutical companies to bring innovative therapies to market and address unmet medical needs.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

MRIguidance–gettingmoreinformationout ofyour MRI data
In an ideal world, a single medical imaging exam would generate 3D images of both bone and the soft tissue without the
use of harmful radiation. However, orthopedic surgeons and radiologists now often choose between a MRI scan for soft
tissueand an X-ray based CT scan for boneinformation.To reducepatient burden and healthcarecosts,they haveto work
with suboptimal information for diagnosisand treatment planning and in some cases,even two examsare required.
MRIguidance now brings this ideal world to reality with BoneMRI.Bone MRI is a software solution that generates a CT-
like image to complement the soft tissue images derived from a MRI scan. For the clinicians Bone MRI works in the
background in aseamlessworkflow without the need of new desktop applications.

41. So what should radiologists do with A.I.?
“Data Wrangler” ?
DICOM 2018, Mainz
42. From factory worker to consultant
• Avoid time-consuming repetitive tasks (factory worker)
• Use A.I. technology for routine tasks and time-consuming
tasks
• Add expertise where it counts
• Exploit modern technology for functional information
• Regain partnership in patient care (Consultant)
BSR annual meeting 2018
44. PUSH or PULL?
• PUSH:
– Radiologists will decide what applications are being used and how
– Will they push the right techniques? Do radiologists know what clinicians
want? Will they accept it? …e.g perfusion imaging
• PULL:
– Radiologists do not adapt -> clinicians will start using it first
– Referring clinicians / insurance / authorities /patients will demand radiologists
to use AI
• Standardisation, accreditation, guidelines (e.g. RECIST for immunotherapy, interstitial
lung disease)
• Economics (hospital)
• Quality (clinicians, patients,…?)

45. Major roadblocks for AI
Sli.do live survey, EuSoMII Annual Meeting, Rotterdam, Nov 3, 2018
46. Possible scenarios for integrating AI
1. A.I. on demand
2. Automated image analysis
3. Automated routing to EPR

P. Lakhani et al. JACR https://doi.org/10.1016/j.jacr.2017.09.044
47. Possible scenarios
1. A.I. on demand
– For a single image or series of images
– PACS radiologist AI server PACS, RIS,
EHR
– Radiologist would be in control of asking relevant
A.I. interpretations
– Requires manual intervention from radiologist

48. Possible scenarios
2. Automated A.I. image analysis
– Exams automatically sent to A.I. server (before reading)
– Analysis “pipeline” starts execution upon reception if
there is a positive match
– modality AI server PACS radiologist RIS, EHR
– Helps to prioritize reading order -> reduce TAT
– Radiologist views A.I.-findings before final report is made
– Radiologist is able to ensure accuracy and validate report

49. Possible scenarios
3. Automated routing
– As in 2. but results are generated and automatically routed to RIS or EPR
– Requires discrepancy management
– AI -> preliminary -> RIS/EHR -> staff radiologist -> final
– Accurate AI needed (highly sens and spec), high confidence
– Fastest TAT although potential risk
– Might increase calls to radiology reading room
– Might have medicolegal consequences

50. Implementation of AI algorithms for radiology
• “Ensuring that algorithms can be SEAMLESSLY integrated into radiologists’
clinical workflow is of paramount importance because if the A.I. tool is
not readily available to the end users in their workflow, adoption in clinical
practice will be less likely to occur.”
(B. Allen, K. Dreyer)
• Interoperability between all systems is prerequisite
• Radiologists have to determine the best model for implementing A.I.
– When, how for what purpose
– What to do with the results and reports
– How to validate the apps? What quality criteria?

Seamless integration of AI with
PACS and EMR, “all-in-one”
Interoperability
Facilitates training of
new algorithms &
applications

Swiss-knife for radiologists: all-in-one
52. Types of marketplaces to expect
1. Vendor-neutral model, launched from PACS
2. Vendor-locked model, embedded in platform
of traditional vendor
3. Cloud-based SaaS model (Apple-store)
BSR annual meeting 2018
53.
54. What business model?
• AppStore model, application on request
• Pay per analysis = fee for each analysis
• Subscription fee = fee per package of monthly analyses
• License = pay for whole platform with limited n
analyses
• Included with modality
• Included with PACS/RIS
BSR annual meeting 2018
56. A.I. is roaring at the start
• AI = racing machine
• What is fuel for AI?
– Sharing of data internally & externally
– Vetted / annotated data
• Where are the roads for AI?
– IT infrastructure in the hospital (interoperability)
– Connected & communicating systems
– Optimal integration in radiological workflow
• AI-ecosystem = traffic regulation
• The responsible pilot remains the radiologist
BSR annual meeting 2018
57. What role should radiologists play?
1. Radiologists are in the lead with AI for HC and should stay there
2. They should pro-acitvely invest in their future now
3. They should guide the new developments instead of undergoing them
4. They should implement AI with a strategic plan and goal of increasing value
5. The should have a crucial role in provision and curation of training data
6. They should inform hospital managers and politicians about their role and
importance in the clinical decison making
7. They should create partnerships with all stakeholders, including hospital IT
managers
8. They should include imaging informatics in radiology training and motivate the
younger generation to embrace this new technology
