"In this sequence, the heart is imaged at every heartbeat following pump injection of gadolinium. This allows dynamic imaging of contrast as it passes from the right ventricle, into the left ventricle, into the myocardium, and following the redistribution. Thrombus being an avascular lesion will be of homogenous low intensity in every phase."
"A long inversion time of ~440 ms is chosen to null any non-vascular lesions (e.g. thrombus) that do not contain gadolinium. This accentuates thrombus by making it very hypointense compared to surrounding tissues which contain gadolinium. Any lesion which is not homogenously hypointense points to an alternative pathology."
"A short inversion time is initially chosen to null the gadolinium-rich myocardium so that any areas of myocardial enhancement are accentuated. The initial inversion time is decided upon by performing a scout at different TI and choosing the TI which nulls the myocardium. This also incidentally results in some fat suppression as fat has a short T1 value (~150 ms). The inversion time is progressively increased as late gadolinium imaging progresses, because gadolinium washes out of the myocardium, and the T1 value increases back to baseline. Thrombus will remain of low intensity, and any underlying infarct will be revealed by subendocardial enhancement."
