TL;DR: Myocardial perfusion scintigraphy with radioactive particles reflects the status of the myocardium beyond diseased coronary arteries, and cases illustrating collateral perfusion, myocardial aneurysms, cardiomyopathy, and venous by-pass grafts are presented.
Abstract: Macroaggregates of albumin labeled with 99mTc and 131I were injected into the coronary arteries in 400 patients undergoing coronary arteriography. The three major coronary artery systems were divided into six groups, based upon coronary arteriography and myocardial perfusion color scintigraphy. Myocardial perfusion could not be predicted uniformly by angiography alone. Myocardial perfusion patterns of each group are presented, together with cases illustrating collateral perfusion, myocardial aneurysms, cardiomyopathy, and venous by-pass grafts. If the size and number of particles injected are carefully controlled, the procedure involves insignificant morbidity and no mortality. Myocardial perfusion scintigraphy with radioactive particles reflects the status of the myocardium beyond diseased coronary arteries.

TL;DR: 99mTc-labelled microspheres were utilized in 50 patients to evaluate extremity perfusion patterns and to provide a qualitative assessment of muscle perfusion.
Abstract: The evaluation of peripheral vascular disease in man includes various clinical and radiographic procedures. Arteriography is useful in the detection of gross anatomical changes but does not provide information about muscle perfusion. 99mTc-labelled microspheres were utilized in 50 patients to evaluate extremity perfusion patterns and to provide a qualitative assessment of muscle perfusion. Correlative studies were carried out comparing perfusion scans with clinical history, arteriographic findings and surgical results.
