Figure 1a. (a) Two-chamber inversion-recovery gradient-echo MR image (4.6/1.2/200 [repetition time msec/echo time msec/inversion time msec], 20° flip angle, 192 x 256 matrix gated to every other R wave) and (b) four-chamber view show extensive infarction of enlarged left ventricle with transmural delayed enhancement (arrows).

Figure 2a. Thrombus (arrows) in left ventricular apex of a patient suspected of having hypereosinophilic syndrome. (a) Transverse contrast-enhanced CT scan. (b) Two-chamber (4.6/1.2/200, 20° flip angle, 192 x 256 matrix gated to every other R wave) and (c) four-chamber myocardial delayed-enhancement MR images delineate and characterize the mass as thrombus by its location, smooth margins, and lack of contrast enhancement.

Figure 3a. Right atrial myxoma (arrows). (a) Dark blood MR image with dual-inversion fast spin-echo pulse sequence (R-R interval/42, echo train length of 24, 192 x 256 matrix gated to every R wave). (b) Myocardial delayed-enhancement MR image (4.6/1.2/200, 20° flip angle, 192 x 256 matrix gated to every other R wave) clearly delineates the margins and attachment of the mass to fossa ovalis.
