Clinical Introduction:
A 21-year-old male with a medical history of scoliosis was referred for an abnormal chest radiograph performed on screening (figure 1). He was asymptomatic with good exercise tolerance. Blood pressure and heart rate were normal. The heart sounds were normal. The pulmonary examination was unremarkable. A treadmill test performed 3 years prior for atypical chest pain was normal. An ECG performed was also normal.
Question:
What abnormality is present in the chest radiograph? DextrocardiaEnlarged right heart borderMediastinal massProminent pulmonary vasculatureSitus inversus.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
