Facial bone scanning by emission tomography.
نویسندگان
چکیده
A single-photon emission tomographic system was used to study the normal anatomy of the facial bones and the usefulness of emission computed tomography in evaluating diseases of the bones of the face. The examination was performed following routine bone scintigraphy and took an additional 20-30 min. The anatomy of the facial bones was well defined, with clear separation of deep and superficial structures. Early experience with tumor, infection, bone grafts, and postirradiation osteonecrosis indicates that useful added diagnositc information can be obtained by this method.

The effect of fasting on Positron Emission Tomography (PET) imaging
As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while before PET imaging is an exampl...
متن کاملHigh-resolution CT scanning of facial trauma.
Computed tomographic (CT) scanning offers a simple, fast, and accurate study of complex maxillofacial trauma especially in the patient with multiple injuries. At the time of CT brain scanning, the facial bones can be scanned with only minimal extra time. High-resolution scanning provides excellent bony detail equal to or better than complex-motion tomography with the advantage of better contras...
متن کاملThe effects of masseter muscle paralysis on facial bone growth.
BACKGROUND Understanding the effects of muscle function on facial bone growth may help us treat children with facial anomalies. Facial bone growth is known to be a result of both genetic and epigenetic influences. One of the main epigenetic factors controlling growth is thought to be muscle action. The purpose of this study was to establish a model of single facial muscle paralysis and to ident...
متن کاملSingle photon emission computed tomography (SPECT) scanning for adolescent back pain. A sine qua non?
Nine cases of adolescent back pain show that a diagnosis of spondylolysis cannot be made on physical examination alone and that single photon emission computed tomography (SPECT) scanning revealed pars interarticularis stress lesions undiagnosable on planar technetium-99 bone scan. As management of spondylolysis differs from other lumbar dysfunctional problems SPECT scanning of children should ...
متن کاملPost-traumatic Bilateral Facial Paralysis
Bilateral facial paralysis is a rare clinical entity. It is also diagnostic challenge which, unlike unilateral facial paralysis, it is can be difficult to recognize because of a lack of facial asymmetry. A 22 year-old man referred for neurological evaluation because of bilateral facial paralysis (House-Brackmann grade V). He has initially presented unconsciousness after he sustained closed head...
