What are the standard planes for cross sectional cardiac imaging?
The oblique orientation of the heart with respect to the body axis requires special planes of imaging. The four-chamber view of the heart captures all four cardiac chambers in a single image and includes the tricuspid and mitral valves. The short-axis view of the heart is perpendicular to the four-chamber view and allows accurate measurement of septal thickness and ventricular free wall thickness. In the short-axis view, the left ventricle is depicted in cross section and appears almost circular. Standard axial images also are commonly used. Coronal images are sometimes used to evaluate the diaphragmatic surface of the heart
