Table 2.

LV segmentation failures in the 5772 image datasets processed using (left) the conventional algorithm and (right) the “same-patient processing” approach, broken down by acquisition protocol type. With the exception of one conventionally processed AC-stress dataset, all failures in the 2886 stress datasets (whether processed conventionally or with the same-patient approach) were associated with pharmacologic stress.
