From: T1 inversion recovery pulse sequence: could it replace T1 spin echo sequence in neuroimaging by improving tissue contrast?

Male patient, 50 years old, diagnosed as metastatic bronchogenic carcinoma to the brain. a T1IR. b T1SE. It revealed that T1IR aided in better delineation of lesions and also in detection of lesions (arrows in a) that were not clearly seen in T1SE (arrows in b). c T1IR. d T1SE. It revealed that T1IR showed a right cortical lesion (arrow in c) that was barely detected in T1SE (arrow in d). e T1IR post-contrast. f T1SE post-contrast. The right cortical lesion enhancement could not be assessed accurately in T1IR post-contrast image due to motion artifacts (arrow in e), and there was also a faint ring enhancement in this lesion in T1SE post-contrast image (arrow in f)
