This document provides an overview of various imaging modalities used for chest imaging including plain chest radiographs, computed tomography, MRI, nuclear medicine scans, ultrasound, and pulmonary angiography. It describes the technical aspects and clinical applications of each modality. Key points covered include how plain chest radiographs remain diagnostic in 80% of cases and involve standard views, as well as how computed tomography is the main further investigation for most chest x-ray abnormalities and certain scenarios like pulmonary embolism.

Anti ulcer drugs and their Advance pharmacology ||
Anti-ulcer drugs are medications used to prevent and treat ulcers in the stomach and upper part of the small intestine (duodenal ulcers). These ulcers are often caused by an imbalance between stomach acid and the mucosal lining, which protects the stomach lining.
||Scope: Overview of various classes of anti-ulcer drugs, their mechanisms of action, indications, side effects, and clinical considerations.

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

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.

4. Computed Tomography
• Numerous
protocols/techniques
depending on clinical
history
• Helical/spiral versus high
resolution
• Contrast
– Renal failure
– Allergy
5. Computed Tomography
• Role of CT
– Main further investigation
for most CXR abnormality
(eg nodule/mass) or to
exclude disease with
normal CXR
– Main investigation for
certain scenarios (PE,
dissection, trauma)
6. MRI
• Multiple planes
• No radiation
• Common Indication
– Pancoast tumour
– Brachial plexus
– Cardiac
– Vascular (aorta)
• Usually targeted
examination (unlike
CT)
Coronal
7. Nuclear Medicine
• Variety of tests: functional rather than
anatomic
• V/Q specific to chest imaging
• Others: bone scan, gallium, WBC etc.
8. Ultrasound
• Limited use in thorax (non cardiac) due to
air in lungs
• Assess pleural effusions
• Mainly used for procedures
9. Chest Radiographs
• PA (posterior to anterior) and Lateral (left)
– Minimizes magnification of heart (heart closest to film)
• Portable (nearly always AP)
– Supine or Erect
• Specialized Views
– Lordotic
– Lateral decubitus (for effusions, pneumothorax)
10. Lordotic View
Better assess apices without bone overlap
11. 1
1: Adequate penetration of
4
a the mediastinum-is the
a thoracic spine seen?
2: Has the patient taken a good
inspiratory effort? About 8-10
7
posterior thoracic ribs should be
seen through the lungs
3: Is there any rotation of the
chest? Assessed by checking
10 the upper thoracic spinous
process (oval) in relation to the
medial ends of the clavicles
(lines ‘a’) - this CXR is rotated to
left
15. Chest Radiograph: Approach and
Normal Anatomy
THERE IS NO ONE APPROACH: BE SYSTEMATIC
• Bone and Soft Tissue including abdomen
• Heart
• Mediastinum-aorta, trachea
• Hila

29. ACINAR PATTERN (CXR)
Radiology: Round or elliptical ill-defined 4-8mm opacities in lung
Microscopic: Portion of lung distal to terminal bronchial (respiratory bronchial,
alveolar duct, alveolar sac and alveoli) is the acinus
CXR close up of acinar pattern
30. ACINAR PATTERN (CT SCAN)
Round or elliptical ill-defined 4-8mm opacities in
lung

together producing a net with small superimposed nodules.

33. EMPHYSEMA:

bronchiole with destruction of walls of involved air
spaces..
BULLA: Gas containing avascularity of lung measuring 1cm or more in
diameter, 1mm thickness

34. Pneumonia (consolidation)
• Air bronchograms would confirm an alveolar process.
• The lung volume should not be lost (may even be
increased).
• Usually all radiographic abnormalities should disappear
after 6 weeks of appropriate antibiotic therapy.
40. Consolidation and follow-up X-rays
• Recommendations are, repeat film at 1, 3 and 7 days to check for
the development of complications.
• Resolution of the X-ray signs always lags behind the clinical
findings
• The X-ray should therefore be repeated 4 weeks later to check for
resolution.
• If there is persistent consolidation at this stage, further investigation
is necessary to exclude an obstructive lesion.
41. SIGNS OF COLLAPSE
DIRECT SIGNS:
• Displacement of fissures
• Loss of aeration
• Vascular & bronchial signs
INDIRECT SIGNS:
• Mediastinal & Hilar displacement
• Elevation of Hemidiphragm
• Compensatory hyperinflation
72. Severe heart failure
• Severe pulmonary edema gives confluent
alveolar shadowing which spreads out from the
hilum giving a 'bat's wing' appearance.
• If this is the cause of generalized shadowing
then upper lobe blood diversion and Kerley B
lines should be present.
• In pulmonary edema hilum may appear
distended and the vessels close to the hilum
may be blurred.
73. Severe heart failure vs. non-
carcinogenic pulmonary edema
• In non-cardiogenic pulmonary edema the heart
size is likely to be normal and there will not
necessarily be sparing of the peripheries.
