May aid CAD detection over ECG; leaves open prospective validation of clinical utility and outcomes.
Does serial exercise thallium-201 myocardial perfusion scanning improve the detection of coronary artery disease compared to rest and exercise ECG in patients with known or suspected coronary artery disease?
Exercise thallium-201 myocardial perfusion scanning is more sensitive than exercise ECG alone and provides complementary value in the non-invasive detection of coronary artery disease.
Dunn et al. (1979) studied this question.
