Abstract:

 Background: One of the major limitations of myocardial scintigraphy is soft tissueattenuation, which could be interpreted as a true perfusion defects, particularlydiaphragmatic and bowel attenuation of the inferior wall.
Objective: The aim of this study was to evaluate the role of adding prone scan to the stressmyocardial scintigraphy.
Setting: Department of Radiology, Nuclear Medicine Section, King Faisal SpecialistHospital and Research Center.
Design: Retrospective study.
Method: Eighty-eight patients with coronary artery disease had myocardial perfusion scanand were reported with and without a prone scan during stress study. All patients in thisstudy had a diagnostic coronary angiogram.
Patients who had coronary angiogram within one month after the diagnostic cardiac scanwere included. Patients who have been admitted to the hospital between the twoprocedures were excluded.
Result: Prone scan had improved the sensitivity (SN), specificity (SP), positive and negativepredictive value (PPV, NPV) of the myocardial perfusion scintigraphy studies. Prone scanshowed that SN, SP, PPV and NPV were, 91.7%, 70%, 78.6% and 87.5% compared tosupine scan, which were 76.6%, 53.6%, 65.4% and 66.7%.
Conclusion: In this study, we have found that the sensitivity and specificity had improvedafter the addition of prone stress scan in myocardial perfusion studies.
Prone scan had helped in differentiating perfusion defects from attenuation artifacts,leading to improvement of detecting the true perfusion defects.
