Polar maps of the study groups demonstrating segmented, mean native T1 in milliseconds. Compared with the control group (n = 22), the native T1 of the human immunodeficiency virus (HIV) infected group at baseline (n = 73) is elevated in all segments. After 9 months of antiretroviral treatment (ART), the native T1 decreased in all segments of HIV-infected participants. The red line indicates the anterior right ventricular insertion site
