  • Nuclear cardiac imaging has been widely used to assess viable myocardium in patients with ischemic heart disease, The assessment of viable myocardium is important in selecting patients who will be benefit from revascularization. Although revascularization is indicated in patients with sufficient myocardium, patients with scar tissue should be treated medically. Nuclear imaging methods including myocardial perfusion SPECT and FDG PET have been shown to be effective modalities for identifying viable myocardium.

  • Purpose: The present study has an objective of effectively separating and making observations on a portion of radiopharmaceutical excreted via digestive organ to remain in the organ and invade a heart shadow. Materials and methods: When heart shadow is blocked by the organ in tests during a resting phase and a loaded phase, additional images were obtained using immobilization device. The immobilization devices were used to tilt the upper body forward from supine position. Results: In the reconstructed image for the separated case, as compared with the case where a part of organ is overlapped with heart, in terms of an overall mean value for each parameter, the end-diastolic volume increased by 2.75 mL, the end-systolic volume decreased by 3.16 mL, the left ventricle cardiac coefficient increased by 3.58%, and the area of defect region decreased by 3.58 and 3.92 cm for loading and resting phase, respectively. Conclusions: In the present study with myocardial perfusion SPECT, overlapped areas of heart and other organs could be effectively separated and visualization by the use of an immobilization device.
