Figure 1 (A) Coronary arteriogram of a 65-year-old woman with effort angina. Severe stenosis is seen in the left anterior descending coronary artery (arrow). (B) Sequential tetrofosmin images. No significant abnormal perfusion is observed on the tetrofosmin images obtained at the time of hospital admission. However, the BMIPP images obtained on the next day show severely reduced uptake in the apex and anteroseptal regions.

Figure 2 (A) Coronary angiogram of a 48-year-old woman with rest angina in the early morning. Seven days later, coronary angiography shows no significant stenosis in either coronary artery. After injection of ergonovine maleate into the right coronary artery, total spasm was provoked (left), with severe chest pain and electrocardiographic changes. After isosorbide dinitrate was injected, the spasm was completely resolved (right). (B) Series of rest tetrofosmin perfusion and BMIPP single-photon emission computed tomography images. No significant abnormal perfusion is observed on the rest tetrofosmin images at the time of hospital admission. However, the BMIPP images show reduced uptake in the inferior region on the next day.
