The recognition of different heart disease was frequently scored by nuclear medicine Physician by determining the location and the extend of the disease. The measurement of the heart volume in nuclear medicine is considered one of the most crucial methods of appraisal the myocardial disorders. The aim of this paper was to study the stroke volume of the heart for patient using SPECT machine. For the scanning, the patient were injected by Technetium labeled with Sestamibi and Tetrofosmin (20 mCi) then they scanned for 45 minutes using SPECT with ECG during the examination. The sample of this study were 50 patients. The quantitative analysis included the stroke volume, cardiac output and ejection fraction. The results of the study showed the upsurge in cardiac output 6.3 + 1.1 L/min (p > 0.05) and ejection fraction 66.8 + 8.4 (p > 0.05). The stroke volume was decreased with increasing of the both age and body mass index.
Key words: Nuclear cardiology, Cardiac output, stroke volume (SV), Ejection fraction (EF)
