Abstract: Cardiovascular diseases are the most common diseases in the developing and developed countries. Among the existing isotopes, thallium-201 and technetium-99 m are two isotopes commonly used in the heart perfusion scan. In this study, we evaluatedthe heart perfusion scans of patients for possible artifact on the bottom and sidewalls of the heart, related to the compression of the right ventricle. The study was conducted in 2014 at Alzahra Center for Heart Nuclear Medicine. Total 200 patients were selected quite randomly for the study. The selection criteria was the ECO of the patients at arrival and especially their right ventricular pressure. Approximately 20-25 mCi of technetium Mi B was injected intravenously to the patients and the Stress Scan Phase was carried out after an interval of 1-1.5 h after injection. The analysis of the results was conducted in the two sections of descriptive and inferential. Based on the results, there is no significant relationship between gender and septal artifact (p = 0.982). According to the results, there were significant relationships between age; ischemia level; diatolic pressure; EF, PAP and septal artifact with the chi-square statistic value of 12.311 (p = 0.006), 123.411 (p<0.0005), 105.42 (p<0.0005), 46.558 (p<0.0005), 100.434 (p<0.0005). This project aims to reduce the incidence of the false positive results. Detection of the artifact in the septal wall reduces false positives in patients’ scans and prevents them from doing excess, aggressive and unnecessary acts of treatment and drug side effects. It also accelerates the timely treatment process and reduces the expenses of patients.
