MRI with ultrashort TE (UTE) has been suggested as useful for morphological assessment of lung as well as CT. However, no reports have been found to study the capability of thin-section MRI with UTE for pulmonary nodule detection and nodule type assessment as compared with thin-section CTs. We hypothesized that pulmonary MRI with UTE has a similar potential for nodule detection and nodule type evaluation as compared with thin-section CT. The purpose of this study was to compare the capability of pulmonary MRI with UTE for nodule detection and nodule type assessment with low- and standard-dose CTs.
