An application of a double inversion recovery (DIR) sequence in breast MR imaging may improve lesion detections by nullifying signals from fat and fibroglandular tissue without using any contrast agent. The purpose of present work was to investigate the effectiveness of the DIR MRI sequence in detections of breast cancers. Firstly, we compared lesion contrasts among several imaging sequences, including contrast-enhanced T1-weighted image (CE-T1WI), DIR image, pre-contrast-enhanced T1WI and T2-weighted image (T2WI) from twenty-four patients. Secondly, we evaluated whether DIR image was useful to detect breast cancers without injecting contrast agent from additional thirty-two patients.
