Patient-specific preprocedural rehearsal devices will allow surgeons to add critical annotations and observations to the imaging data set preoperatively. With CT scanning, numerous x-ray beams and a set of electronic x-ray detectors rotate around the patient, measuring the amount of radiation being absorbed throughout his/her body. Different body parts absorb the x-rays in varying degrees. In the current study, all the CTs used for ESS were graded as technically adequate, so subjective quality for intraoperative navigation was not negatively impacted. /Contents 4 0 R>> It's also the most reliable imaging technique for determining if the sinuses are obstructed and the best imaging modality for sinusitis. The referring providers were categorized into three groups: sinus surgeons, other members of the otolaryngologyhead and neck surgery (ENT) department exclusive of sinus surgeons, and all other non-ENT health care providers. Copyright 2002 by the American Academy of Family Physicians. endstream 2013; 270(1):149-155. Historically, sinus CT at our institution (a multispecialty academic medical center) was performed in the radiology department by using one of two imaging protocols, based on whether the CT was intended for diagnostic purposes or intraoperative navigation, neither of which would be considered a low-radiation dose screening sinus CT. Chen Y-L, Liu C-M, Huang H-M. THEY NEED 1MM OR LESS. After your exam the technologist will escort you out of the office. CT scans can provide much more detailed information about the anatomy and abnormalities of the paranasal sinuses than plain films. He underwent transfacial and endoscopic resection of the mass with postoperative radiation therapy. I'm not a radiologist but I believe it has to do with overlaying the images in a particular manner and the use of specialized software.
