Representative examples of LV thrombus assessment by DE-CMR. Two representative examples of thrombus by DE-CMR tissue characterization as compared to (contrast-enhanced) transthoracic echo. (A) Large intracavitary thrombus within LV apex (yellow circle) concordantly identified by both DE-CMR and echo. Note that thrombus appears “etched” on standard DE-CMR (top, inversion time 250-350 msec) and homogenously black in long inversion time (bottom, inversion time = 600 msec) imaging. (B) Small mural thrombus (yellow circle) on standard DE-CMR, despite negative echo. For both examples, surgical resection enabled thrombus verification based on histopathology (right, hematoxylin and eosin stain, low power).
