We evaluated the capability of pulmonary MR imaging of zero echo time (zTE) in assessing patients with pulmonary nodules detected by low-dose computed tomography (LDCT). Consequently, pulmonary thin-section MR imaging with zTE was useful in nodule detection and was considered at least as effective as low-dose thin-section CT. This excellent acquisition method of zTE-MRI is turned out to be radiation-free, quiet and relatively insensitive to cardio-respiratory motion, which is important for the detection and follow-up of pulmonary nodules.
