Purpose: Cochlear implantation in patients with vestibular schwannomas is of increasing importance and interest. Two remaining challenges are the assessment of conduction of the cochlear nerve and the possibility of postoperative surveillance with magnetic resonance imaging. The aim of the current study was to assess follow-up imaging and determine the visibility of the internal auditory canal after vestibular schwannoma resection and cochlear implantation as well as in patients with persistent vestibular schwannomas and cochlear implants in place.

However, in atypical cases the discrimination can be difficult and may vary between individual raters. The aim of this study was to evaluate interrater reliability of WML differentiation between MS and FD patients.

Methods: Multiparametric MRI (mpMRI) was performed in 150 consecutive patients divided into two groups of 75 patients. One group received a rectal preparation with a cleansing enema and endorectal gel filling (median age 65.
Background: Nonsteroidal anti-inflammatory drug (NSAID)-exacerbated respiratory disease (N-ERD) comprises the triad of chronic rhinosinusitis with nasal polyps (CRSwNP), asthma, and intolerance to inhibitors of the cyclooxygenase-1 enzyme. The impact of omalizumab on prevention of aspirin-induced hypersensitivity in N-ERD patients with and without atopic sensitization has not been thoroughly addressed.
Objective: To investigate the effect of omalizumab treatment on aspirin tolerance in atopic and nonatopic N-ERD patients.
Objectives: To evaluate image quality by first use of LumiVision® in dynamic MR swallowing, a contrast medium consisting of biological substances versus a gadolinium-buttermilk mixture in patients who underwent Nissen fundoplication due to gastroesophageal reflux disease (GERD).
Methods: The protocol of this retrospective study was approved by the local Institutional Review Board. A hundred twenty-nine patients (146 examinations) underwent a dynamic MR swallowing study (at 1.
The aim of this study was to evaluate whether stapes prostheses can be visualized with less metal artifacts and therefore more accurately on cone beam computed tomography in comparison to computed tomography imaging. Recent studies have shown that cone beam computed tomography has advantages when imaging metal artifacts. Patients with hearing loss or vertigo, who have undergone stapedotomy, often present a challenge for otologic surgeons.

Although a rare condition after heart transplantation, it is a potential cause of significant morbidity, including vomiting, aspiration and pneumonia. Moreover, impaired gastric emptying alters the pharmacokinetics of immunosuppressive medication with increased risk of severe side effects.
View Article and Find Full Text PDFBackground: Roux-en-Y gastric bypass (RYGB) is the second most frequently performed bariatric procedure worldwide. While pouch migration is a common phenomenon after sleeve gastrectomy, it has hardly been documented after RYGB so far.
Objectives: The aim of this study was to correlate the diagnostic performance of gastroscopy of the gastroesophageal junction with 3-dimensional computed tomography (CT) during postoperative care of patients revised due to weight regain after RYGB, with particular attention to intrathoracic pouch migration (ITM) and pouch volume.
Introduction/purpose: Weight regain and weight loss failure after bariatric surgery are important issues that may require a weight regain procedure. Three-dimensional-computed tomography (3D-CT) is a well-established method allowing exact measurements of pouch volume. The aims of this study were to prove the applicability of swallow MRI as a non-ionizing procedure and compare it to 3D-CT in patients after weight regain procedures following RYGB.

This study aimed to investigate PLSE in various pathological lumbar conditions.
Methods: This retrospective study included the MR images of the lumbar spine of 279 patients (age range 18-82 years) without cardiovascular, renal or hepatic diseases, 79 of whom had low-grade disc degeneration, 101 combined endplate and facet joint degeneration, 53 axial spondyloarthritis and 46 infectious spondylodiscitis.
Background: Roux-en-Y gastric bypass (RYGB) is a well-established surgical method for morbid obesity; however, weight regain (WR) after initially good results may be considered an issue, the treatment of which has found no consensus yet.
Objectives: The aim of this study was to compare the different surgical methods treating WR after RYGB that are used at the Vienna Medical University in a larger number of patients, concerning further weight loss, complications, and reoperations.
Setting: University hospital, Austria.
Purpose: To evaluate the diagnostic performance of swallowing MRI of the gastroesophageal junction (GEJ) in the postoperative care of patients after laparoscopic antireflux surgery (LARS) MATERIAL AND METHODS: In this institutional review board-approved prospective study, 79 symptomatic patients (mean age, 52.3 years; range, 26-80 years) were evaluated after laparoscopic Nissen fundoplication. MRI findings were correlated with revision surgery, endoscopy, and high-resolution manometry (HRM) as standard of reference.

Purpose: To compare densities of corneal epithelial dendritic cells (DCs), corneal subbasal nerves, and conjunctival epithelial immune cells (EICs) between patients with dry eye disease (DED) with and without graft-versus-host disease (GVHD) using in vivo confocal microscopy (IVCM).
Methods: This study included 54 patients who had moderate to severe DED either associated with (n = 33) or without (n = 21) chronic GVHD. In addition to evaluating clinical parameters of DED, images obtained by laser-scanning IVCM of the central cornea and superior tarsal conjunctiva were analyzed to measure densities of corneal epithelial DCs, corneal subbasal nerves, and conjunctival EICs.
Purpose: Posterior tibial tendon dysfunction is the most common cause of acquired asymmetric flatfoot deformity. The purpose of this study was to determine and compare the diagnostic value of MRI and high-resolution ultrasound (HR-US) in posterior tibial tendon dysfunction (PTTD), and assess their correlation with intraoperative findings.
Materials And Methods: We reviewed 23 posterior tibial tendons in 23 patients with clinical findings of PTTD (13 females, 10 males; mean age, 50 years) with 18MHz HR-US and 3T MRI.
Purpose: To evaluate corneal endothelial cell density (ECD) in patients with dry eye disease (DED) compared to an age-matched control group.

Purpose: To evaluate whether levels of corneal subbasal nerve fiber length (SNFL) in dry eye disease (DED) could prognosticate the level of improvement in signs and symptoms after treatment.
Design: Phase IV, double-masked, randomized clinical trial.
Participants: Sixty patients with meibomian gland dysfunction-associated DED and 27 age-matched controls.
