Relationship between Slice Thickness to Artery Coronary Diagnostic Information on the Reconstruction of Maximum Intensity Protection (MIP)
Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 6
Abstract
Introduction: The selection of appropriate slice thickness on the processing of Maximum Intensity Projection (MIP) is crucial to obtain diagnostic information clearly on the coronary artery Cardiac Multi-Slice Computed Tomography (MSCT) examination in detecting abnormalities found in the coronary arteries. Objective: As Maximum Intensity Projection (MIP) required a certain slice thickness to get the exact information to optimally diagnose coronary artery, this research aimed at determining an accurate slice thickness to obtain a clear picture of the coronary arteries required in image reconstruction. Methods: This type of research is a quantitative experimental approach, using a sample of 10 patients that underwent MIP coronary artery reconstruction on the slice thickness variation of 5, 10, 15, 20 and 25 mm. The image of coronary arteries results is assessed subjectively by 3 radiologists to assess the diagnostic information by filling out the questionnaire. The data analysis was done by correlation test. Result: Since the result of the p-value is 0.024 (p <0.05), it is concluded the existence of a significant relationship between the slice thickness with diagnostic information. Furthermore, the negative correlation coefficient of – (0.925),indicated that the relationship between slice thickness with diagnostic information is in opposite directions meaning the thinner the slice thickness the clearer the diagnostic information and the thicker the slice thickness, the blurred the diagnostic information. Conclusion: From this study it can be concluded that there is a relationship between the slice thickness with diagnostic information on the treatment of coronary artery MIP with a negative correlation coefficient = - 0.925 meaning the smaller the slice thickness, diagnostic information on the coronary arteries become apparent but the larger the slice thickness, the resulting diagnostic information is increasingly unclear. MIP reconstruction of the coronary arteries can produce clear diagnostic information to the slice thickness 5 and 10 mm.
