Myocardscintigrafie met thallium-201 na dipyridamol-infusie

– Thallium-201 myocardial imaging after exercise is widely used for the detection of coronary artery disease. This study was performed to introduce thallium-201 myocardial imaging after infusion of dipyridamole (Persantin), a potent coronary dilator. This non-invasive method can be used for patients unable to perform sufficient exercise.

Fifty-three patients (40 men and 13 women) with a syndrome with chest pain who were unable to perform sufficient exercise were studied with dipyridamole-thallium imaging and coronary arteriography. 39 patiënts (74) had significant coronary artery disease. There were 33 patients (62) with a positive dipyridamole-thallium imaging. They all had significant coronary artery disease. Sensitivity and specificity-were 85 and 100, respectively.
