Quantitative Cardiovascular Magnetic Resonance (CMR) imaging has been widely used in detection of myocardial diseases. In this study, T1 rho and T1 mapping MR imaging were performed in subjects with and without alcohol consumption to assess the impact of drinking on the heart. The results suggested that compared with healthy controls, heavy alcohol consumption may lead to detectable changes in myocardial tissues, while moderate alcohol consumption showed no significant difference. In addition, T1 mapping was more sensitive to detect myocardial changes caused by alcohol than T1 rho.
