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

Accidentally discovered posterior fossa mass. a T1IR pre-contrast. b T1SE pre-contrast. Posterior fossa lesion at left cerebellopontine angle that was better identified in T1IR than in T1SE as it appears with hypointense signals and higher lesion CNR than surroundings in T1IR with better delineation between its border and the adjacent left middle cerebellar peduncle (arrows in a, arrows in b). c T1IR post-contrast. d T1SE post-contrast. After giving intravenous contrast media, the lesion appeared with homogenous enhancement in both sequences with no superiority of each of these sequences (arrows in c, arrows in d)
