Stress/Rest 99mTc-MIBI SPECT and 123I-BMIPP Scintigraphy for Indication of Surgery With Coronary Artery to Pulmonary Artery Fistula

Stress/Rest (99m)Tc-MIBI SPECT and 123I-BMIPP scintigraphy for indication of surgery with coronary artery to pulmonary artery fistula.

A 45-year old man was admitted to our hospital with chest pain occurring suddenly upon exercise and disappearing with rest within several minutes. A continuous murmur was heard at the upper sternum border. Conventional electrocardiography showed no evidence of myocardial ischemia. Coronary angiography and cardiac catheterization demonstrated a fistula originating from the left coronary artery t...

Gated 99mTc-MIBI myocardial perfusion SPECT in patients with right bundle branch block but without evidence of coronary artery disease

Introduction: We aimed to investigate the effect of right bundle branch block (RBBB) on perfusion and functional parameters in dipyridamole stress/rest Tc99m-MIBI gated myocardial perfusion SPECT (GSPECT) which may be helpful in interpretation of myocardial perfusion imaging. Methods: We studied 73 patients with low pre-test likelihood of coronary artery disease in two groups:  38 patients wit...

Midventricular Takotsubo Cardiomyopathy on 99mTc-tetrofosmin and 123I-BMIPP SPECT

Myocardial impairment detected by late gadolinium enhancement in hypertrophic cardiomyopathy: comparison with 99mTc-MIBI/tetrofosmin and 123I-BMIPP SPECT.

PURPOSE Myocardial fibrosis is considered to be an important factor in myocardial dysfunction and sudden cardiac death in hypertrophic cardiomyopathy (HCM). The purpose of this study was to compare myocardial fibrosis detected by late gadolinium enhancement (LGE) on cardiac MRI with myocardial perfusion and fatty acid metabolism assessed by single photon emission computed tomography in HCM. M...
