Define enlarged cardiac silhouette

A cardiac CT (computed tomography) scan is a painless imaging test that uses x-rays to take detailed pictures of your heart and its blood vessels.This occurs in patients with slow fluid accumulation, compared with a normal cardiac silhouette seen in patients with rapid accumulation and tamponade. Thus.

Chest X-ray demonstrates enlarged cardiac silhouette with increased pulmonary vascular markings.Subjectively, the cardiac silhouette appears larger than expected, but specific chamber enlargement may or may not be evident.Worth mentioning, there is a medical term known as the cardiothoracic ratio (CTR), which is a measurement on a chest X-ray (CXR) of the width of the heart divided by the width of the chest.It can also be due to an expiratory radiograph, pericardial effusion, a mediastinal mass projecting over the heart, or in some cases epicardial fat (in order of likelihood).
