Characterization of Cardiac Abnormality in Single Photon Emission Computed Tomography Images Using Image Processing Technique

Abstract

This study consists of 51 patient's different age, sex whom were referred to cardiology clinic for myocardial perfusion scintigraphy. To identify the percentage of the functioning areas of the heart by computer programthe study was also designed to code the heart SPECT image according to the function, differentiate between normal & abnormal area and To measure the size of the heart and the defected area. The patient underwent myocardial perfusion rest and stress scan taken after 30-40min, 50-60min respectively by acquiring 32 frames at 30sec/projectionwith the patients in supine position, in addition that in stress test the patients were injected with the pharmacological stress Persantine (0.567*patient weight) diluted with normal saline to have a total volume of 20ml. The study was conducted at International medical center (IMC) in SAUDIA ARABIA, JADDAH. Between(Oct2013-May2014). The results showed that there is a significant difference between the functioning percentage of the heart at rest and stress concerning the mild and moderate classification of heart perfusion reduction.
