Extraordinary use of nuclear scintigraphyJan 7, 2011 13:29 EST
A study on the use of myocardial perfusion imaging showed that patients underwent a median of 15 procedures involving radiation exposure, of which a third received cumulative doses. On the other hand, a NEJM paper showed that in a large, national registry, only 38% of patients without known heart disease who underwent elective invasive angiography had obstructive coronary artery disease.
Ten million nuclear heart scans are performed per year: why are we exposing our patients unnecessarily to such a high dose of radiation?
