Dilatation of left ventricular cavity on stress thallium scan as an indicator of ischemic disease.
The left ventricular cavity seen on a stress thallium scan is normally smaller than that on a non-stress scan. This size differential can be used as an adjunct in the interpretation of borderline relative changes in perfusion seen in coronary artery disease or in the elimination of some false-negatives secondary to balanced lesions.
