Our CT Scan tables have a weight limit of 660pounds. Our Advanced Sequences and Protocols for conditions like chronic sinusitis, hearing loss, ear infections, dysphagia, sleep apnea, tonsils and adenoid problems, vertigo, allergies, and head and neck cancer. Whether using cone-beam CT or low-dose multidetector CT, a decreased radiation dose comes at the expense of declining image quality, and this diminished signal-to-noise ratio degrades the assessment of soft tissues more than bones.23 From an interpretive standpoint, the minimum acceptable image quality is highly subjective, and this is reflected by tremendous variability in radiation dose for sinus CT. A survey of in-office, hospital-based, and outpatient imaging facility CT scanners found a 10-fold difference between the highest and lowest radiation dose for sinus CT,24 and a separate report identified an 18-fold variation between minimum and maximum dose across 30 institutions when the sinus CT was being specifically performed for guidance during ESS.25 Although some of this variability can be attributed to the use of different CT scanners, substantial variability can also be found across sites even when using the same CT scanner model.26 When assuming that agreement can be reached on an acceptable subjective image quality for diagnosis and surgical navigation, a question can be raised as to whether or not a higher image quality is needed to preserve the fidelity of imaging guidance during ESS. Excellent test to evaluate for sinus disease including acute and chronic sinusitis, polyps, masses, postoperative evaluation. government site. Intl J Ped Otorhinolaryn.

[12] although recent developments alleviated the latter limitation. Of all the patients who had a sinus CT, the proportion that ultimately underwent ESS with imaging guidance differed based on the specialty of the referring provider (p < 0.0001). 2005 Oct. 34(5):317-22. [17]. It does not imply the use of a contrast agent. Based on Medicare reimbursement, the total estimated saving was $147,628. Acute cerebral venous sinus thrombosis (VST) is a rare form of stroke, and establishing a correct diagnosis can be challenging due to its diverse and typically delayed clinical presentation [1,2].VST is most common in young women and is associated with pregnancy/puerperium, use of hormonal contraceptives, hypercoagulable states, and malignancy [3,4]. Metson R, Gliklich RE, Cosenza M. A comparison of image guidance systems for sinus surgery. Sinusitis is one of the most common diseases treated by primary care physicians. At the same time, the examination table is moving through the scanner, so that the x-ray beam follows a spiral path. Nasal endoscopy revealed bilateral profuse mucus that required suctioning.

The benefit of a common sinus CT protocol would be negated if a patient proceeded with ESS at an external facility that may have required a repeated preoperative CT. [10], The relevant anatomy is that of the paranasal sinuses, orbits, and cranial base and is comprehensively treated in many textbooks such as Stammberger'sFunctional Endoscopic Sinus Surgery(1991). Image-guided surgery, using either of the most recent optical or electromagnetic systems, accommodates for head movement. [QxMD MEDLINE Link]. MEDTRONIC SEAFARING, FUSION. Diagnostic imaging is generally used in cases of recurrent or complicated sinus disease. In endoscopic sinus surgery, the main advantage is to avoid disrupting hazardous areas such as the brain and orbit. (Aurora, Uptown, Superior, Castle Rock, Highline, Lafayette, Lakewood, Thornton, Wheat Ridge), NeuroQuant, a medical software, provides volumetric measurements of brain structures and compares the volumes to normative reference data adjusted for age, sex, and intracranial volume. Paranasal sinus mucoceles are benign, expansive, cystic lesions which arise from retention of mucus secretions. [11], Anesthesia is induced on a normal operating table. The cohort consisted of 2759 women (44.6%) and 3428 men (55.4%), with an average age of 53.6 years 16.7 years (mean SD). NEWS He had a slight right cheek swelling visible externally. Second, the CT scanner(s) used must be able to meet the technical requirements set forth by the imaging guidance system, such as the minimum field of view and slice thickness. I can't read your physicians mind, but I highly doubt if they were getting the CT scan to look for a cancer. CTDI: ~10-20 mGy Place skin marker on the patient's right cheek prior to scanning Setup: Head first supine , lateral scout from below the chin through the top of the skull Patient positioned so that the IOML is perpendicular to the table top Only use the flat sponge , NO LENS SHIELD TO BE USED Recurrent or refractory symptoms, despite treatment, or suspicion of complicated infection, abscess, or neoplasm, warrants further evaluation.

VIDEO: Balloon sinus surgery with NuVent EM Balloon Sinus Dilation, Nearly 29 million Americans suffer from chronic rhinosinusitis,1 with more than 500,000 sinus surgeries performed annually.2, Chronic rhinosinusitis can have significant effects on health and quality of life -- more disabling than angina, congestive heart failure, and back pain.3, Annual direct costs to society are $4.3 billion,4 and when medical therapy fails, endoscopic sinus surgery is the treatment of choice.3. CT Sinus Cat Scan Quick Reference Guide for Physicians. Old image-guided surgery (IGS) systems used an articulated arm (shown) and required the patient's head to be taped to the operating room bed. Today with numerous CT scan manufacturers around the world and with numerous makes and models of scanners constantly changing it is essentially impossible to provide a set of protocols for what would likely be 100 different scanners. Powered instrumentation in functional endoscopic sinus surgery II: a comparative study. The electronic medical records for all outpatients undergoing sinus CT between October 1, 2010, and September 30, 2014, were queried.

Immuno-compromised patients are at increased risk for complicated bacterial or fungal infections. You are being redirected to Determinants of outcomes of sinus surgery: A multi-institutional prospective cohort study. The primary objective was to highlight the potential for cost saving and to raise awareness of radiation dose reduction, with the understanding that the derived estimates were not absolute and would vary from one site to the next based on the unique nature of individual practices. DISCUSSION The use of a universal sinus CT protocol for both intraoperative navigation and routine diagnostic imag-ing represents an easily overlooked opportunity for eliminating redundant imaging. [QxMD MEDLINE Link]. 7 0 obj However, when symptoms are recurrent or refractory despite adequate treatment, further diagnostic evaluations may be indicated. Dalgorf DM, Sacks R, Wormald PJ, Naidoo Y, Panizza B, Uren B, et al. The site is secure. Because reimbursement records were not available to determine exact amounts billed and collected for each CT, Medicare rates were applied. 8 0 obj ( I am the one with the possible lump in mouth and sinus issues)Just wanted to know what to expect from the scan on Monday. In an attempt to decrease sinus CT utilization, we synthesized and implemented a single sinus CT protocol that was universally acceptable for diagnostic imaging and intraoperative navigation, regardless of whether ESS was anticipated at the point of order entry. With the newer systems (see the second image below), the headset moves along with the head, so registration is maintained throughout the procedure, although frameless registration can also be performed. Biofilm maturity studies indicate sharp debridement opens a time-dependent therapeutic window. For some CT exams, a contrast material is used to enhance visibility in the area of the body being studied. Difficult anatomic relationships can more easily be understood and treated with the assurance that the critical landmarks are secured. Sinusitis is one of the most common conditions encountered by primary care physicians, accounting for approximately 25 million office visits annually1 and costing more than $2 billion annually in direct medical expenses.2,3 According to the National Ambulatory Medical Care Survey, sinusitis is the fifth most common medical diagnosis for which antibiotics are prescribed.4,5.

Our Advanced Sequences and Protocols for conditions like Multiple Sclerosis,Alzheimers disease, stroke, minor head trauma, and other neurologicalconditions. However, given that there is significant variability in payer mix across practices, the use of Medicare rates allowed for a more generalizable result. Furthermore, no significant difference was noted in other parameters (eg, blood loss, complications). The CT scan acquisition protocol used for the authors' needs consists of a helical, 2-mm-thickness axial CT scan with the use of a specially designed headset incorporating built-in metallic.

In a conventional x-ray exam, a small burst of radiation is aimed at and passes through the body, recording an image on photographic film or a special image recording plate. For sinus CT at the authors' institution, a single imaging protocol was begun and deemed acceptable by neuroradiologists and surgeons for diagnostic imaging and intraoperative guidance. Future developments in surgical simulation will also likely contribute to broaden the applications of image-guided surgery. 2000 Jun. The goal of sinus surgery is to restore ventilation and drainage while preserving mucosa. Even though some centers use a unique acquisition protocol, many centers still have a specific 3D navigation protocol and a specific standard CT protocol for sinus CT scans . In all the cases used for intraoperative navigation, the sinus surgeons deemed the sinus CTs acquired with the universal protocol to be technically adequate. Functional endoscopic sinus surgery: concepts, surgical indications, and instrumentation.
