Twenty-one patients with ischemic heart disease were studied by resting 99mTc-methoxyisobutyl isonitrile (MIBI) gated SPECT images using a 3 head rotating gamma camera (Picker/Shimadzu: PRISM 3000). The data were acquired over 360 degrees in 20 (x 3) steps, each of which was 70 beats. The systolic wall thickening index (%WT) was calculated as (ES count-ED count/ED count x 100), using the circumferential profile analysis of ED and ES short axial images. The %WT was correlated well with LVEF obtained from contrast ventriculography (r = 0.85, n = 17). By using high speed (3 head) rotating gamma camera, we have shortened the time of collecting MIBI gated SPECT data, and this method can provide useful information on ventricular function.

D015637	Gated Blood-Pool Imaging	Radionuclide ventriculography where scintigraphic data is acquired during repeated cardiac cycles at specific times in the cycle, using an electrocardiographic synchronizer or gating device. Analysis of right ventricular function is difficult with this technique; that is best evaluated by first-pass ventriculography (VENTRICULOGRAPHY, FIRST-PASS).

D015899	Tomography, Emission-Computed, Single-Photon	A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.

D017202	Myocardial Ischemia	A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).
