The VEX-test for myocardial scintigraphy with thallium-201 and sestamibi: effect on abdominal background activity.


UNLABELLED High abdominal background activity of 99mTc-sestamibi may interfere with the diagnosis in studies in which a coronary vasodilator is used; supplemental dynamic exercise might reduce this problem. METHODS Clinical and angiographic determinants of subdiaphragmatic-to-myocardial activity ratios were measured on immediate poststress left anterior… (More)
