Indications
This view is ideal for patients who are unable to move their arm as per the standard ...
Article
Knee (oblique view)
The knee oblique view is an additional projection requested to examine the knee joint in greater detail, often in the absence of a CT scanner. The view is comprised of both an internal and external oblique.
Indications

Article
Pediatric hand (lateral view)
The lateral hand view for pediatrics is an orthogonal view taken along with the PA view of the hand. The lateral view is used to primarily assess for foreign bodies and/or displacement of fractures/dislocations.
Indications
This view is useful in assessing suspected dislocations, fractures or ...
Article
Baumann angle
Baumann angle, also known as the humeral-capitellar angle, is used for the evaluation of the displacement of pediatric supracondylar humeral fractures. It is measured on a frontal radiograph, with elbow in extension.
This angle is formed by the humeral axis and a straight line through the epiph...
Article
Abdominal radiography
Abdominal radiography can be useful in many settings. Before the advent of CT, it was a primary means of investigating gastrointestinal pathology and often allowed indirect evaluation of other abdominal viscera.
Indications
Although abdominal radiography has lower sensitivity and specificity t...

Axillary view
An axillary view (also known as a "Cleopatra view“) is a type of supplementary mammographic view. It is an exaggerated craniocaudal view for better imaging of the lateral portion of the breast to the axillary tail. This projection is performed whenever we want to show a lesion seen only in the a...
Article
Chest (lateral decubitus view)
The lateral decubitus view of the chest is a specialized projection that is now rarely used due to the ubiquity of CT. It is chiefly used in the pediatric population.
Indication
Undertaken to demonstrate small pleural effusions, or for the investigation of pneumothorax and air trapping due to...
Article
Pediatric forearm (horizontal beam lateral view)
The horizontal beam lateral forearm view for pediatrics is one of two modified trauma projections in the forearm series, examining the radius and ulna.
Indications
This view is ideal for patients who are unable to move their arm as per the standard forearm positioning technique but require as...
Article
Chest (lateral view)
The lateral chest view examines the lungs, bony thoracic cavity, mediastinum, and great vessels.
Indications
This orthogonal view to a frontal chest radiograph may be performed as an adjunct in cases where there is diagnostic uncertainty. The lateral chest view can be particularly useful in as...
Article
Pediatric forearm (PA view)
The posteroanterior forearm view for pediatrics is one of two modified trauma projections in the forearm series, examining the radius and ulna.
Indications
This view is ideal for patients who are unable to move their arm as per the standard forearm positioning technique but require assessment...
Article
Pediatric hand (PA view)
The posteroanterior hand view for pediatrics is part of a two view series examining the phalanges, metacarpals, carpal bones and distal radioulnar joint.
