![]() In addition, the features at pre- and postprocedural MRI will be discussed to help ensure that diagnostic radiologists may be of greatest use to the ordering physicians. We aimed to evaluate the association of audio-vestibular symptoms with the presence of vascular loops and vascular contact in cerebellopontine angle (CPA) and the internal auditory canal (IAC) using 3Tesla MRI. They enter the meatus, or porus acusticus, of the internal auditory canal as. The purpose of this review is to provide an overview of the most useful MRI sequences for internal auditory canal and labyrinthine imaging, review the relevant anatomy, and discuss the expected appearances of the most commonly encountered pathologic entities. Magnetic resonance imaging is the most sensitive method of detection and. Nevertheless, despite the widespread use of MRI for these purposes, many radiologists remain unfamiliar with the complex anatomy and expected imaging findings with such examinations. MRI showed duplicated and narrow right IAC with non-visualisation of right cochlear nerve and normal facial nerve in the anterosuperior canal (figure 2). It is also extensively used in pre- and postoperative evaluations, particularly in patients with vestibular schwannomas and candidates for cochlear implantation. Such techniques include the decompression of the internal auditory canal or placement of a silicon or Teflon cushion between the compressing artery and CN VIII. It is used to evaluate normal anatomic structures, evaluate for vestibular schwannomas, assess for inflammatory and/or infectious processes, and detect residual and/or recurrent cholesteatoma. Magnetic resonance imaging (MRI) of the internal auditory canal (IAC) is a non-invasive, painless diagnostic imaging procedure that uses using radio waves and a. The MRI studies were performed using a 1.5 T system without intravenous gadolinium administration with reconstruction on axial. MRI is firmly established as an essential modality in the imaging of the temporal bone and lateral skull base. repeat MRI with dedicated pituitary protocol may be performed. ![]()
