Low-resolution scout images are acquired to determine the imaging planes that define the local coordinate system of the heart. (A) Axial images of the heart at the base (left) and at the mid-ventricle (right) are used to plan (dashed lines) a pseudo-long axis image by orienting the slice plane such that it passes through the chamber of the left ventricle on both images. The pseudo-long axis image (B) is used to plan a double oblique long axis (dotted line) perpendicular to this image and along the length of the left ventricle. The resulting image (C) is that of a “true” long axis. The local coordinate system of the heart is now defined, and higher resolution images of the heart in the short axis and long axis views can be acquired. The solid white line perpendicular to the double oblique long axis scout image defines the short axis of the heart parallel to the mitral valve plane.
