What Student Need to Know about Ear, Nose And Throat Imaging In Radio Diagnosis

For clinical inner ear scanning, MR imaging scanners with a magnetic field strength of 1. 5T or 3T are routinely used. The relatively recent introduction of commercial 7T scanners potentially enables an increased SNR, resulting in more detailed imaging of anatomic structures. Concerning inner ear imaging, the visualization of delicate and smallsized inner ear structures might benefit from such highresolution imaging. The auditory pathway is divided into the outer, middle, and inner ear and the central auditory pathway. The outer ear is composed of the auricle and external auditory canal. The tympanic membrane is located at the end of the EAC and separates the EAC from the middle ear. The middle ear contains ossicles, nerves and muscles (stapedius and tensor tympani). The inner ear consists of the cochlea, vestibule and semicircular canals encased in the bony otic capsule. The airfilled middle ear and fluidfilled inner ear are connected by two membranecovered openings the oval and round windows. The
