Lateral chest X-ray Let’s take a second to try to understand why it is that theheart appears bigger than normal on AP studies. Imagine you are holding a flashlight, pointing it so that the circle of light appears against a white wall a foot away from you. Now imagine holding a pen ...
Radiography Technique Projections The standard radiographic views for evaluation of the chest are the posteroanterior (PA) and lateral projections with the patient standing; such projections provide the essential requirement for proper three-dimensional

The issue of target motion due to breathing is reduced by placing the animals supine so that the chest can expand freely however, the posterior elements of the vertebral bone are highly irregular especially in comparison to the skull surface. In rats, an average of about a 33% signal loss ...

Fig. 3.1. Normal inspiratory chest a Frontal examination reveals a normal lung volume. The criteria for a normal lung volume are: ( a ) less than one-third of the heart is projected below the hemidiaphragm; ( b ) the diaphragm is rounded, and the sixth or seventh anterior rib (ar) int...
Currently, radiographic studies such as chest X-ray or CT scan are used to quantify the severity of chest wall deformity by deriving the pectus index (PI). PI, else- where called pectus severity index, is defined at the level of greatest deformity as the maximum transverse dia- meter of ...
An artificial intelligence (AI) tool can accurately identify normal and abnormal chest X-rays in a clinical setting, according to a study published inRadiology. Chest X-rays are used to diagnose a wide variety of conditions to do with the heart and lungs. An abnormal chest X-ray can be an...
