We have to shorten inspection time in order to decrease patient's physical burden. Early image is applicable to diagnosis.

Background We attempted to bring forward the start time of scan in delayed myocardial Gd enhancement in cardiac MRI. The term of whole examination was shortened by bringing forward the start time and therefore a patient’s physical burden must decrease. Evaluation Cardiac MRI was performed in patients with old myocardial infarction (OMI), dilated cardiomyopathy (DCM), hypertrophic cardiomyopathy (HCM), cardiac sarcoidosis, and others. 20 patients (female:10, male:10) ranged in age from 18 to 82 years participated in this study. We evaluated the images by the delayed times of 5 and 10 minutes using Phillips Achieva 1.5T. As evaluation criteria, CNR (contrast to noise ratio) and enhanced volume were employed, visual assessments were performed by 2 radiologists using image viewers. Wilcoxon signed rank test was performed to compare CNR. Discussion About visual assessments, 18 patients were able to be diagnosed by the images delayed time 5 minutes. As a result of CNR and enhanced volume ratio, the significant difference was not accepted. Conclusion Our results show the images with delayed time of 5 minutes available for diagnosis. The physical burden to a patient is also mitigated.
