HRT2 imaging is a highly reliable and lower-cost alternative to T1C for follow-up surveillance scans in patients with VS.

This represents an overall cost and charge savings for this 50-patient cohort of $7,401 and $64,200, respectively. Cost-minimization analysis demonstrated cost and charge differences of $148.02 and $1,284 per patient per scan, respectively. Intraobserver and interobserver reliability estimates (κ) were 0.88 to 1 for both T1C and HRT2, indicating very high reliability. Pearson correlations ( r) between T1C and HRT2 were 0.991 and 0.973 for radiologists 1 and 2, respectively, with no statistically significant differences ( P ≤ 0.05) between imaging techniques. Once the data were analyzed, appropriate economic evaluation was performed utilizing institutional-, federal-, and literature-based estimates of cost and incidence/prevalence. Measurements were assessed by Pearson product-moment correlation coefficients, and differences were analyzed by Student t test. Vestibular schwannoma size in anteroposterior, mediolateral, and superoinferior axes were measured by two neuroradiologists, both blinded to previous measurements, for 50 randomized patients with T1C and HRT2 on two separate occasions.

Retrospective case-control analysis, systematic review, and economic evaluation. CPT Code Description Auditory System 69100. All rights reserved.To determine if high-resolution T2-weighted (HRT2) magnetic resonance imaging (MRI) is a comparably accurate and economical alternative to the gold standard of contrast-enhanced T1-weighted (T1C) MRI for surveillance of know vestibular schwannomas (VSs). It is used to evaluate normal anatomic structures, evaluate for vestibular schwannomas, assess for inflammatory and/or infectious processes, and detect residual and/or recurrent cholesteatoma. Gadolinium Intralabyrinthine schwannoma Magnetic resonance imaging Sensorineural hearing loss Sudden sensorineural hearing loss.Ĭopyright © 2017 Elsevier Inc. MRI is firmly established as an essential modality in the imaging of the temporal bone and lateral skull base. These findings have implications for reducing cost, time, and adverse events associated with gadolinium administration in patients presenting with sudden or ASNHL. Non-contrast high-resolution T2WI alone can detect ILSs with 84-100% sensitivity, suggesting that gadolinium may be unnecessary to exclude ILSs on screening MRI. The list of Radiology CPT codes is updated as below at the latest information and also add new updates as well. The median size of the ILSs was 4.4mm (☒.9mm) and most (18/31) were intracochlear in location. The 5 ILSs with discordant results were correctly identified upon consensus review. Bilateral 77059 Brachial Plexus 71550 / 71552. The sensitivity, specificity, and accuracy were 1.0, 1.0, and 1.0 for Observer 1 0.84, 1.0, and 0.96 for Observer 2 0.90, 1.0, and 0.98 for Observer 3. The matrix below contains all of the CPT 4 codes that National Imaging Associates. Sensitivity, specificity, and accuracy were calculated using the post-contrast T1WI as the "gold standard." A consensus review of cases with discordant results was conducted. When an ILS was identified, its location and size were recorded. Three board-certified neuroradiologists reviewed only the T2WI from these 67 cases. 37278-9 37278-9 : MR Brain+IAC WO contr 37278-9 : MR Brain and Internal auditory canal WO contrast Additionally, you can get information about the 37278-9 LOINC code in TXT format. The purpose of this study was to determine if non-contrast high-resolution T2WI alone are adequate to exclude these uncommon intralabyrinthine tumors.ģ1 patients with ILSs and 36 patients without inner ear pathology that had dedicated MRI of the IAC performed with both non-contrast T2WI and post-contrast T1WI (T1 weighted image) were identified.

However, there are concerns that non-contrast MRI may not detect labyrinthine pathology, specifically intralabyrinthine schwannomas (ILSs). Non-contrast MRI of the internal auditory canal (IAC) using high-resolution T2WI (T2 weighted image) has been proposed as the primary screening study in patients with sudden or asymmetric sensorineural hearing loss (ASNHL).
