Although the brain is the head's most prominent organ, there is much more to image at the top of the body than just the cerebrum and cerebellum. The IAC Routine ExamCard for investigation of hearing loss uses the SENSE Head coil and implements a T2-weighted sequence of the brain to exclude tumor. The IAC Vertigo ExamCard adds a high resolution scan to evaluate the brain stem and posterior fossa, where the pathology responsible for vertigo often is found. The IAC Tinnitus ExamCard covers patients with suspected tinnitus, the subjective or objective perception of sound. The IAC Tinnitus ExamCard may also be refined in the near future with the addition of a BOLD fMRI sequence. The most frequent examined middle ear pathology is cholesteatoma, which eventually can completely destroy the ossicles of the middle ear and can subsequently affect the inner ear, resulting in complete deafness. In the past, the inability to discern between cholesteatoma and other middle ear pathology compelled exploratory surgery for all patients whose CT scan merely showed an obliterated middle ear with no convincing evidence of a potentially aggressive lesion.


Symptoms of Labyrinthitis typically include loss of balance (vertigo), nystagmus (involuntary eye movement), nausea, hearing loss, tinnitus (ringing in the ears) and mild headaches. We have 3 locations in Calgary: North, North West and South and an office in each Okotoks, Cranbrook and Creston, and Invermere, British Columbia. Therefore, the tinnitus simulator consists of hearing protection headphones that realistically simulate the age-related hearing loss and an external device for playing 8 typical tinnitus sounds. Outside of the braincase are the subjects of head and neck MRI: the skull base, cranial nerves, ears, orbits and neck. Jan is creating at least 15 ExamCards to encompass the diverse anatomy of the head and neck region. The Flex-S coils return maximum signal by virtue of their proximity to the region-of-interest.
Jan has developed ExamCards for IAC Routine, IAC Vertigo and IAC Tinnitus, which are available on Philips' NetForum for immediate download to eligible users. Subsequently, bilateral Flex-S coils are used and a T2- weighted DRIVE sequence is applied to obtain ultra-high resolution images of small inner ear anatomy, such as the nerves.
In addition to the routine T2-weighted brain survey, DRIVE and T1-weighted PCA sequences, IAC Tinnitus employs an MRA sequence with and without contrast to evaluate posterior fossa vessels. With CT, it is often impossible to confirm the presence of a cholesteatoma in a completely obliterated middle ear, but with specific MRI sequences and Flex-S coils, definitive diagnoses can now be made, Dr. Jan, the preferred RF coils for head and neck studies are the flexible SENSE Flex-S coils, which provide excellent SNR even for centerline anatomy when placed close to the skin. In particular the age-related high-frequency hearing loss increases in addition the effect of tinnitus.
The most common tumor of the salivary glands is a pleomorphic adenoma (benign mixed tumor).


In effect, the tinnitus has saturated the contralateral side with sound, so activation migrates to adjacent same-side areas, an effect we can see with BOLD fMRI," he explains. However, when high resolution is needed to visualize known, close-to-the-surface pathology or anatomy, such as nerves, TMJ joint or eyeball, Dr. CLEAR is fantastic because it allows signal homogenization from left to right without a drop-off at the center.
The third and final sequence - a 3D, T1-weighted, contrast-enhanced PCA sequence - focuses again on the inner ear and on the cerebropontine angle to exclude enhancing lesions, labyrinthitis and meningeal enhancement.
Jan Casselman is creating a battery of ExamCards that will account for virtually every head and neck MRI study possible. The images are far superior to those we've acquired in the past, when we could hardly see the larynx due to low signal and low spatial resolution.
This Master Class set of head and neck ExamCards emphasizes SENSE, CLEAR and close-to-the-skin positioning of surface coils. In the orbits, high SNR and matrix are necessary to resolve the tiny muscles on the globe of the eyeball and the optic nerve at its entrance to the globe. We would lengthen sequences to five or six minutes to build signal and resolution, but eventually patients would swallow. Now, we have so much signal that we can reduce scan time to two minutes, or, alternatively, increase scan time to 3.5 minutes in cooperative patients to provide even higher resolution. For example, we acquired some beautiful images of the globe of the eye in which we think we can see the retina.
