Figures
- FIG 1.
Cholesteatoma with positive findings on both HASTE and RESOLVE in a 4-year-old girl with delayed speech. Both axial HASTE (A) and RESOLVE (B) demonstrate a region of restricted diffusion in the left external auditory canal (arrow). Note greater signal hyperintensity of HASTE compared with the RESOLVE image. Adjacent opacified mastoid air cells demonstrate relatively faint signal (curved arrow).
- FIG 2.
Example of a cholesteatoma seen on HASTE imaging with equivocal findings on RESOLVE. The patient is a 13-year-old boy with a history of bilateral cholesteatomas status post multiple prior surgeries who presented with recurrent hearing loss in his right ear. Axial HASTE (A) image clearly depicts a 0.6-cm focus of restricted diffusion in the right hypotympanum (arrow). Although faint signal is seen in this region on corresponding axial RESOLVE (B) image (arrow), the intralesional signal is insufficiently intense to warrant a certain diagnosis.
- FIG 3.
Cholesteatoma visible on HASTE but not on RESOLVE in a 69-year-old woman who had undergone a left tympanomastoidectomy approximately 15 months prior for resection of a cholesteatoma. MR imaging was performed to assess residual or recurrent disease. Axial (A) HASTE image demonstrates a well-demarcated 0.6-cm focus of restricted diffusion in the left anterior mesotympanum (arrow). No abnormal signal was seen on corresponding RESOLVE image (B).
