Abstract
-
BACKGROUND: Patients with acoustic neuroma(AN) may have sudden sensorineural hearing loss(S-SNHL). The prevalence of AN in patients with S-SNHL is 0.8% to 30%. Thus, a lot of diagnostic tools have been used to screen of AN from S-SNHL. Usually, Gadolinium(Gd) enhanced MRI have been recommended. Recently, Fast spin echo MRI(FSE MRI) have been shown to be equally effective in detection of acoustic neuroma as Gd enhanced MRI.
OBJECTIVE
To assess the value of FSE MRI as a screening test in patients with S-SNHL.
MATERIALS AND METHODS
From January 1995 to August 1996, We evaluated FSE MRI and Gd enhanced MRI for 45 patients with S-SNHL. RESULT: We could screen 4 cases of AN patient from them.
CONCLUSION
FSE MRI is effective in the detection of AN in S-SNHL patients.
