Abstract
BACKGROUND: Ultrahigh-field (UHF) MRI advances towards clinical use. Patient compliance is generally high, but few large-scale studies have investigated the effects experienced in 7T MRI systems, especially considering peripheral nerve stimulation (PNS) and caregiving. PURPOSE: To evaluate the quantity, the intensity, and subjective experiences from short-term effects, focusing on the levels of comfort and compliance of subjects. STUDY TYPE: Prospective. POPULATION: In all, 954 consecutive MRIs in 801 subjects for 3 years. FIELD STRENGTH: 7T. ASSESSMENT: After the 7T examination, a questionnaire was used to collect data. STATISTICAL TESTS: Descriptive statistics, Spearman’s rank correlation, Mann-Whitney U-test, and t-test.
