From: Performance of TGSE BLADE DWI compared with RESOLVE DWI in the diagnosis of cholesteatoma
A 51-year-old male with primary cholesteatoma in the right middle ear confirmed by right mastoidectomy. Axial T1WI (a) and T2WI (b) showed the anatomical location of the cholesteatoma (arrow) in the right middle ear. c, e: TGSE BLADE (b1000) and RESOLVE (b1000) DWI showed a restricted diffusion lesion (high signal) in the right mastoid bone. d, f: The ADC on TGSE BLADE and RESOLVE DWI was 0.689 × 10− 3 mm2/s and 0.791 × 10− 3 mm2/s, respectively. However, the cholesteatoma lesion (arrow) was not as clear on RESOLVE DWI as on TGSE DWI. Moreover, the structures of the nasal cavity were obviously distorted on the RESOLVE b1000 (e) and ADC (f) maps, whereas almost no distortion was observed on the TGSE b1000 and ADC maps. Images (c and e) show the geometric deformation values of the entire image for images with a score of 4 (no distortion) and 2 (moderate distortion)
