Abstract—3D ultrasound (3-dimensional sonography) when combined with sonosalpingography, it provides detailed information regarding internal and external contours of the uterus, without the need for radiation contrast material or surgical intervention. This study was done because of the need of such diagnostic modality that is highly accurate as well as least invasive. A descriptive study was conducted on 50 infertile females to assess the diagnostic value of 3-dimensional SHG in reference of diagnostic hystero-laproscopy (DHL) assuming as gold standard. It was found that sensitivity of 3-dimensional SHG reasons of tubal patency, ovarian pathology and uterine cavity was found 97.6%, 90.91% and 71.43% respectively. And diagnostic accuracy of 3-dimensional SHG in reference of DHL for tubal patency, ovarian pathology and for uterine cavity was found 96%, 92% and 96% respectively. So it can be concluded from present study that 3-Dimensional sonohysterography is an efficient tool to assess women with infertility. Its sensitivity, specificity, and diagnostic accuracy is comparable to hysterolaproscopy.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
Pulmonary Thromboembolism - etilogy, types, medical- Surgical and nursing man...VarunMahajani
Disruption of blood supply to lung alveoli due to blockage of one or more pulmonary blood vessels is called as Pulmonary thromboembolism. In this presentation we will discuss its causes, types and its management in depth.
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.
3. Professor Ian Donald and his colleagues in Glasgow published a paper in
LANCET IN 1958 (Diasonograph )

RECENT ADVANCES
15. • One of the main advantages of 3D imaging of the uterus, on
the other hand, is the capacity to reconstruct the coronal plane.
• 3D ultrasound involves the acquisition of a series of 2D images
that can then be displayed collectively in a variety of imaging
modalities.
• 3D ultrasound scanning consists of four basic steps:data
acquisition, volume analysis and processing, image animation
and archiving of volumes.
3-DIMENSIONAL ULTRASOUND
16. • Three-dimensional ultrasound provides an accurate picture of
the uterine cavity, serosal surface, and the myometrium in
between.
• accurate measurement of organ dimensions and volumes,
• improved anatomic and blood flow information,
• improved assessment of complex anatomic anomalies,
• better specificity in regard to the confirmation of normality,
• standardization of the sonographic examination procedure,
• scanning times with cost effective use of equipment and
sonographer time,
• possibility of post processing the volumes,
• telemedicine and tertiary consultation
ADVANTAGES OF 3D USG OVER 2D
17. This format has been found to be useful for:
- Evaluation of uterine shape abnormalities (e.g.
Mullerian duct abnormalities) in conjunction with SIS
- Evaluation of intra-uterine device (IUD) location
- Problem-solving for uterine fibroids (particularly
% submucosal component) and fibroid mapping
- Endometrial polyps
- Intrauterine adhesions( synechie)
- Adenomyosis ( Junctional zone)
CORONAL PLANE IMAGING IN 3D ULTRASOUND
19. CONGENITAL
UTERINE
ANOMALIES
• 3D ultrasound has contributed
the most and has become the
investigation of choice
• Ability to show both internal
uterine cavity and external
uterine contour in CORONAL
SECTION
• Accurate, noninvasive,
outpatient diagnosis of
congenital uterine anomalies.
20. IUCD
– Location of intrauterine
contraceptive devices:
displacement of intrauterine
contraceptive devices can
reduce their effectiveness.
The coronal plane images
provided by 3D ultrasound
provide views of both the
arms and shaft of the device
and the relation of these to
the endometrial cavity.
21. FIBROID
• 3D ultrasound has recently been
used to map the exact location of
fibroids in relation to the
endometrial cavity and
surrounding structures.
• This is extremely important in
triaging patients for surgery and
• Potentially useful in monitoring the
reduction in the size of fibroids in
patients receiving gonadotrophin-
releasing hormone analogs or
following uterine artery
embolization.
22. ENDOMETRIAL POLYPS
- Assessing whether or not a
patient has an endometrial
polyp and then determine the
size of the polyp and its pedicle.
-Studies have demonstrated that
the uterine cavity, endometrial
lining and myometrium are best
visualized using
sonohysterography, and that
these images are further
improved by the use of 3D
ultrasound.
23. UTERINE SYNECHIAE
-With SIS ,2D ultrasound may
present a diagnostic clue of
adhesions through the presence of
bands seen within the endometrial
echo.
-However, 3D imaging well
delineates the true narrowing or
“bands” adherent across the cavity
-3D ultrasound has better sensitivity
and predicted adhesions and cavity
damage with greater accuracy than
HSG in patients with suspected
Asherman’s syndrome. (Knop man et
al)
24. ADENOMYOSIS
-The most specific 2D feature for the
diagnosis of adenomyosis was
presence of myometrial cysts (98%
specificity; 78% accuracy), along with
heterogeneous myometrium
-On 3D TVS , the best markers
were JZ difference ≥4 mm and JZ
infiltration and distortion (both 88%
sensitivity; 85% and 82% accuracy,
respectively)
- The JZ may be regular, irregular,
interrupted, not visible,not assessable
25. 3D AND INFERTILITY
Sonography is employed for four main purposes in the
approach to female in fertility:
(1) to identify abnormal pelvic anatomy;
(2) to detect pathology causal or contributory to
infertility;
(3) to evaluate cyclic physiologic uterine and
ovarian changes; and
(4) to provide surveillance and visual guidance
during infertility treatment.
26. COMPONENTS OF INFERTILITY SCAN
1. Ovarian reserve assessment ( AFC, ovarian volume)
2. Polycystic Ovaries ( follicle count and volume)
3. Follicular development monitoring
4. Uterine cavity assessment ( 2D , SIS , 3D )
5. Endometrial receptivity assessment ( 3D and dopplers)
6. Ovarian-Endometrial Synchrony ( dopplers)
7. Corpus luteum Development
8. Cysts and Tumours ( 2D , 3D and other modalities)
9. Tubal Patency ( SIS , HyCoSy)
10.Assessment of ovarian hyperstimulation
27. SONO AVC
• SONO AVC is a 3D software with
automated calculation the no. of
follicles in individual ovaries and
gives good count assessment.
• Very useful for antral follicle
count assessment in IVF
protocols.
• For diagnosis of PCOS and early
prediction of ovarian
hyperstimulation when 3D
doppler is employed alongside
28. VOCAL
• VOCAL(virtual organ comp aided analysis) is an inbuilt
software in an advanced 3 D machine
which helps in measuring volume and
vascularity of any structure e.g ovary,
endometrium etc.
• Used by infertility specialist to assess
ovarian volume, stromal and
endometrial volume under infertility
protocol &PCOS
• In case of PMB, to evaluate
endometrial volume and chances of
malignancy (under research)
29. COLOR DOPPLER IN INFERTILITY
• Doppler ultrasonography can be
utilized to assess the endometrial
receptivity by determination of
endometrial and subendometrial blood
flow which affects embryo transfer and
implantation
• 3D US vascularization gives
schematical information about all
vessels and additionally quantifying
blood flow in the selected volume.
• 3D vascular indices can be measured:
vascular index (VI), flow index (FI), and
VFI (vascular flow index).
30. 3DPOWER DOPPLER AND VOLUME
POWER DOPPLER TO ASSESS
ENDOMETRIAL RECEPTIVITY
3D VASCULARIZATION INDICES
34. 3D SALINE INFUSION
HYSTEROGRAPHY
• 3D SIS provides coronal
plane and storage of data
• CORONAL view enhances
the detection rate of
endometrial pathologies
• Compared to hysteroscopy,
3D SHG showed sensitivity
94.2% and specificity of
98.5%,
36. LIMITATIONS OF 3D
One of the main underlying prerequisites to a quality 3D image is a good
2D image.
For a good volume acquisition in 3D imaging an adequate elevation focus is
important with optimized imaging settings to enhance 3D imaging
Artifacts in 3D reconstructions can be less readily recognizable and have
the potential to distort an image enough to alter the diagnosis fact,
Considerable “learning curve” associated with the manipulation of 3D
ultrasound by the examiner. To optimize image as per Various settings,
which are machine-dependent require training and time
For near optimal coronal image and demarcation best time is the luteal
phase of cycle or when endometrial thickness ≥ 5mm
37.
38. • Elastography is an ultrasound imaging technique that measures tissue
stiffness in both physiological and pathological states.
• To obtain an elastographic image, a source of “stress” or “strain”
promotes tissue deformation to assess this stiffness (Stoelinga, 2014).
• There are three main types of ultrasound elasticity imaging:
-Potential areas of investigation include distinguishing
a) endometrial polyps from submucous pedunculated myomas,
b) endometrial cancer from benign endometrial thickening,
c)cervical cancer from normal cervix, and
c) leiomyomas from adenomyosis (Stoelinga, 2014).
ELASTOGRAPHY
39. It features the latest elastography that makes it easier for users to
distinguish benign from malignant masses through acquiring the strain
ratio between the target and reference area faster than the previous
models. This means that it could identify the isoechoic lesions that were
missed by 3D ultrasound.
5D ULTRASONOGRAPHY
The state of the art machine differs from the 3D/4D machines in
making highly precise calculations automatically.
A special feature of the machine is that the 3D information is
digitalized in the form of ‘tissue-blocks’ which then can be
stored and transferred.
40. • Intraoperative ultrasound has gained an established role in many
surgical procedures.
• It has been introduced mainly to overcome the two major drawbacks of
endoscopy:
a)the ability to show only the surface of the organs and
b)the lack of manual palpation of the structures.
• Hysteroscopic 5D ultrasound can be used during the resection of
Intrauterine adhesions and uterine septa, hysteroscopic myomectomy,
and for differentiation between septate and bicornuate uteri.
• Robotic 5D ultrasound is the latest version of intraoperative
sonography. It can accurately identify and track the target tissue during
the surgical procedures.
ENDOSCOPIC ULTRASOUND
41.
42.
43. • Microbubbles, are acoustically active nanoparticles containing gases
which are compressible ,act as ultrasound contrast agents ,specific to
molecular targets in intravascular compartment only due to their size
• With this technology , another dimension of ultrasound has become a
reality: diagnosing and monitoring pathological processes at the
molecular level.(CEUS) is continuous, dynamic and in real time.
• These agents can be targeted to specified sites by
1) manipulating the chemical properties of the microbubble shell
2)through conjugation of disease/molecule-specific ligands
3)antibodies to the microbubble surface.
• For ovarian cancer, CEUS may highlight tumor neovascularization in
developing microscopic tumors . In addition, as malignant vascular
channels are often incompetent, the resultant extravasation of RBCs
and contrast agent may be detected sonographically.
MOLECULAR IMAGING(Contrast enhanced)
44. • “Ultrasound biomicroscopy” allows real time in-vivo visualization of
histologic structures OTHERWISE seen with microscopy of resected
sectioned tissue.
• Malignant invasion of the underlying stroma is well visualized
• Thus, non-invasive imaging is possible allowing for real time,
dynamic and repeated histologic evaluation ,previously requiring
biopsy, staining and microscopy.
• For example, cervical lesions including hyperplasia, dysplasia and
malignancy are well differentiated with assessment of the mucosa,
connective tissue, epithelium and microvasculature.
