What is a cardiac shadow?
A cardiac shadow refers to the silhouette of the heart as seen on a chest X-ray or other imaging modalities. It represents the outline of the heart and surrounding structures, helping radiologists assess heart size, shape, and any potential abnormalities. An enlarged or distorted cardiac shadow may indicate conditions such as cardiomegaly or heart disease. Proper interpretation of the cardiac shadow is essential for accurate diagnosis and treatment planning.
