This study investigated the feasibility of ultrashort echo time (UTE)-MRI to evaluate the radiologic findings of idiopathic pulmonary fibrosis, using high resolution CT (HRCT) as the reference standard. UTE-MRI is inferior to HRCT in identifying the details of lung parenchyma. The results suggest that UTE-MRI is equivalent to HRCT. In addition, inter-method agreement between UTE-MRI and HRCT were equal to inter- and intra-observer agreement for UTE-MRI for evaluating disease findings. Moreover, performance analyses demonstrated that UTE-MRI efficacy for detecting radiologic findings of pulmonary fibrosis, such as reticulation, traction bronchiectasis, and honeycombing were similar to that of HRCT.
