Dizziness and giddiness [R42] / Other specified personal risk factors, not elsewhere classified [Z91.89], Reason for Study: ^Reason: r/o central vertigo, for posterior circulation stenosis, vestibular neuritis History: r/o central vertigo, for posterior IAC MRIThe brainstem, cerebellum, vermis and tonsils are normal. The inner ear structures, cochlea, vestibule, semicircular labyrinth are normal. The internal auditory canals are normal with delineation of the facial, cochlear and vestibular nerves. No evidence of signal abnormality, mass or abnormal enhancement is noted. Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal.MRA NeckThe exam is non diagnostic since the timing of contrast bolus appears to be missed.The examination needs to be repeated without additional charge if clinically indicated.
1. No abnormal signal intensity, no structural abnormality on IAC MR examinations.2. Normal brain MRA.3. Non diagnostic neck MRA. The examination needs to be repeated without additional charge.
