4 BASIC TYPES OF DENSITY - air , water /soft tissues, metal /bone , fat
Two substances of the same density, in direct contact, cannot be differentiated from each other on an x-ray.
This phenomenon, the loss of the normal radiographic silhouette (contour), due to loss of difference in density is called the silhouette sign.

Couples presenting to the infertility clinic- Do they really have infertility...Sujoy Dasgupta
Dr Sujoy Dasgupta presented the study on "Couples presenting to the infertility clinic- Do they really have infertility? – The unexplored stories of non-consummation" in the 13th Congress of the Asia Pacific Initiative on Reproduction (ASPIRE 2024) at Manila on 24 May, 2024.
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.

How to read a Chest X Ray film (Radiograph).pptx
1. CHEST X-RAY
Dr. Suresh Managutti MBBS MD
Associate Professor
Department of Anatomy
SDMCMSH, Dharwad
2. Introduction
Chest X-Ray is one of the most frequently requested hospital investigations.
It is readily available and inexpensive in comparison to other imaging studies.
The basic interpretation is of utmost importance in answering several clinical
questions at hand.
It is an important tool to complement both history and initial clinical
examination.
3. BASIC CHEST X-RAY INTERPRETATION
A. Patient details
Name of the patient
Age
Date
4. B. Quality
• Image quality influences interpretation
• Quality is influenced by radiographic technique and patient factors.
• First determine if the clinical question can be answered.
• Check the image for – Projection, rotation, inspiration, penetration and
artefacts.
5. 1. Projection
• Look to see if the film is antero-posterior (AP) or postero-
anterior (PA) view
• With an AP view the X-ray beam is in front the patient and the
X-Ray placed at the back, and the other way round for PA.
• The standard CXR is PA but many emergency CXRs are AP.
• The CXR projection has an important bearing on the
interpretation of the structures.
6.

10.
11. 2. Orientation
• Identify the left/right markings
• Identify the anatomical structures, erect/supine.
• Do not always assume that the heart will always be on the left because
certain pathologies can result with mediastinal shift, dextrocardia can also
be a possibility.
• You do not have to solely rely on just the CXR markings.
12. 3. Rotation
• Identify the medial ends of the clavicles and select one of the
thoracic vertebra spinous processes that falls between them.
• The medial ends of the clavicles should be equidistant from the
spinous process, if that’s not the case then the X-Ray is
rotated.
13.
14. 4. Inspiration (Degree of inspiration)
• To judge the degree of inspiration, count the number of ribs above the
diaphragm.
• The midpoint of the right hemi-diaphragm should be between the 5th and
7th ribs anteriorly.
• The anterior end of the 6th rib should be above the diaphragm as should
the posterior end of the 10th rib.
• If more ribs are visible the patient is hyperinflated
• If fewer it indicates inadequate inspiration
• Poor inspiration will make the heart look larger, give appearance of basal
shadowing and cause the trachea to appear deviated to the right
15.

17.
18. 5. Penetration
• To check the penetration, look at the lower part of the cardiac shadow
• The vertebral bodies should be barely visible through the cardiac shadow at
this point.
• If they are clearly visible then the film is over penetrated and you may miss
low density lesion.
• If you cannot see them at all then the film is under penetrated and the lung
fields will appear falsely opaque (white).
• The left hemidiaphragm should be visible to the edge of the spine
• When comparing X-Rays first determine if the level of penetration is similar.
21. 1. TRACHEA
• It should be central or slightly deviated to the right.
- In case of deviation decide if is due to rotation or pathology
• View the carina, angle should be between 60 –100 degrees.
• Because it contains air, it appears darker (blacker/radiolucent).
• Trachea normally narrows at the vocal cords (T3/T4)
22. 2. HILAR STRUCTURES
• Also called lung root, consists of the major bronchi and pulmonary vessels
(veins/arteries).
• The hila are not symmetrical but consist of the same basic structures.
• The lymph nodes are also present but no visible unless abnormal.
23.
24. 3. LUNGS
• The lungs occupies the largest portion of the thoracic cavity.
• The lungs are assessed and described by dividing them into upper, middle and
lower zones.
• The lung zones do not equate to lung lobes e.g. The lower zone on the right
consists of middle and lower lobes.
• Compare left with right.
• Compare an area of abnormality with the rest of the lung on the same side.
• If there is any asymmetry decide which side is abnormal
25. 4. PLEURA AND PLEURAL SPACES
• The pleura are only visible when there is an abnormality present.
• This can be due to pleural thickening and fluid or air accumulating in the
pleural spaces.
• Lung markings should reach the thoracic wall
26.
27. 5. COSTOPHRENIC ANGLE AND RECESS
• The costophrenic recesses are formed by hemidiaphragms and chest wall.
• They contain the rim of the lung bases which lie over the dome of each
hemidiaphragm.
• These angles are known as the costophrenic angles.
• Costophrenic angles should form acute angles that are sharp to the point.
31. 7. HEART
• The heart lies more to the left of the thoracic cavity.
• The heart is assessed by means of the cardio-thoracic ratio (CTR).
• CTR = Cardiac width : Thoracic width
• CTR > 50% is abnormal – PA view only
• The left hemidiaphragm should be visible behind the heart.
• The hemidiaphrams do not represent the lowest point of the lungs.
32.
33.
34. 8. THE MEDIASTINUM
• The mediastinum contains the heart and great vessels (Middle mediatinum)
and potential spaces in front of the heart (anterior mediastinum), behind the
heart (Posterior mediastinum) and above the heart (superior mediastinum).
• These potential spaces are not defined on a normal CXR, but their awareness
can help in describing location of disease processes.
• There are several structures in the superior mediastinum that should always
be checked. These include aortic knuckle, aorto-pulmonary window and the
right para-tracheal stripe.
35.
36.
37.
38. 9. SOFT TISSUE
• Normal fat planes are clearly defined in the soft tissues.
• They appear as smooth layers of low density (black), between layers of
relatively dense (whiter) muscles.
• Irregular low density within soft tissues may be as a result of tracking air as a
result of injury to the airways or pleura.
• This is known as surgical emphysema and produces the distinctive clinical sign
of palpable subcutaneous ‘bubble wrap’.
39.
40. 10. BONES
• The most dense tissue visible on CXR.
• Look for fractures, dislocation, subluxation, osteoblastic or osteolytic lesions
etc.
41. APPROACH TO CXR PATHOLOGY
a. The CXR is an important tool to complement both history and initial
clinical examination.
b. Low density structures appear dark(black/radiolucent) and high density
are whitish (opaque).
c. Abnormalities need to be described in detail.
d. Identify the most striking abnormality first. However, once you are done
with this, it is vital to check the rest of the image.
