Role of Multi-detector CT and MRI in Diagnosis of Congenital Inner Ear Anomalies
Sponsor: Assiut University
Summary
Evaluation of combined value of Multi-detector computed tomography (MDCT) and Magnetic resonance imaging (MRI) in the diagnosis of congenital abnormalities of the inner ear and internal auditory canal in patients with congenital hearing loss and preoperative evaluation of cochlear implant candidates.

Every patient will be subjected to 1\. MSCT examination: All patients will undergo MSCT (Siemens somatom 32 slice ,16 slice ,GE bright speed 16 slice ) Non contrast high-resolution CT of the temporal bone with the following parameters:{ 0.75-mm collimation, 130 kvp, 20 mA, topogram length 265}. Patients will be scanned in the supine position with craniocaudal direction. Scanning will be parallel to the orbito-meatal line from the lower margin of the external auditory meatus and extended upward to the arcuate eminence of the superior semicircular canal, as seen on the lateral topogram. Followed by image reconstruction in both the axial and coronal planes to evaluate the inner ear and its malformations, The initial data sets will be reconstructed at 0.6 mm slice thickness. The raw axial image data set can be reconstructed with a section thickness of as little as 0.3 mm to obtain high-quality coronal reformatted images. A 512 × 512 matrix is used, and all the images are reviewed wit
