The advent of 3D navigation imaging has opened new borders to the endoscopic surgical approaches of naso-sinusal inflammatory and neoplastic disease. This technology has gained in popularity among otolaryngologists for endoscopic sinus and skull base surgeries in both adults and children. However, the...
Conclusion:In our center, utilization of 3D navigation sinus CT protocols significantly increases radiation exposure. Otolaryngologists should be aware of this significant increase and should attempt to decrease the radiation exposure of their patients by limiting unnecessary scan orders and by evaluating...
Background/Objective: Computerized tomography scan (CT scan) of the nose and paranasal sinuses plays a key role in preoperative evaluation of patients undergoing endoscope sinus surgery (ESS) for chronic sinusitis. The objective of this study was based on a comparative study among findings of ...
Compare the area on the right side where the maxillary sinus ostium (O) was observed on the previous CT scan. There is no opening now, only the gray tissue completely blocking the ostium. Not surprisingly, this patient had a great deal of pain as a result of that blockage. Although there...
sinus from the skin wounds at the injury site. a99mtc-hmpao scan was performed to assess forosteomyelitis. there is a focal area of tracer accumulation in the right chest wall at the anterior end of the fifth and seventh ribs. on the 24-hour images, there is a change in the spatial ...
In the head/neck/mouth area, CT scanning is used for surgical planning for craniofacial and dentofacial deformities, evaluation of cysts and some tumours of the jaws/paranasal sinuses/nasal cavity/orbits, diagnosis of the causes of chronic sinusitis, and for planning of dental implant ...
A sinus CT exam is used to both diagnose sinus disease and to detect a narrowing or obstruction in the sinus drainage pathway. A spine CT test is most commonly used to detect aherniated discor narrowing of the spinal canal (spinal stenosis) in people with neck, arm, back, and/orleg pai...
CT scan of Sinuses is done to diagnose sinus diseases, as well as to detect obstruction or narrowing in the sinus drainage pathway. CT scan of the Abdomen and Pelvis is done to look at the abdominal and pelvic organs, which include liver, spleen, pancreas, kidneys, and adrenal glands along...
naso‑sinusal inf l ammatory and neoplastic disease. This technology has gained in popularity among otolaryngolo‑gists for endoscopic sinus and skull base surgeries in both adults and children. However, the increased tissue radiation required for data acquisition associated with 3D navigation ...
