This study evaluated the clinical significance of pharyngeal retention to predict aspiration in patients with dysphagia.At videofluoroscopy, was found 108 (28%; 73 males, 35 females; mean age, 60 years) 386 a suspected deglutition disorder. Swallowing function assessed videofluoroscopically. The amount residual contrast material valleculae or piriform sinuses graded as mild, moderate, severe. frequency, type, and grade were assessed.Pharyngeal caused by weakness paresis 103 (95%) patients....
Background In Crohn disease, differentiation between active intestinal inflammation and fibrosis has implications for treatment, but current imaging modalities are not reliably accurate. Purpose To evaluate the predictive value of gallium 68 (
To compare the diagnostic performance (detection, local staging) of multiphasic 64-detector row computed tomography (CT) with that gadobenate dimeglumine-enhanced 3.0-T magnetic resonance (MR) imaging in patients suspected having pancreatic cancer.The institutional review board approved this prospective study, and all provided written informed consent. Multidetector CT MR were performed 89 (48 women aged 46-89 years [mean, 65.6 years] 41 men 46-86 65.3 years]) cancer on basis findings from...
To assess prospectively the effect of section width in multi-detector row computed tomographic (CT) evaluation patients with acute flank pain who are suspected having or known to have urinary stone disease.This study was approved by ethics committee authors' university, and written informed consent obtained from all patients. One hundred forty-seven (age range, 11-101 years; mean, 51.4 years +/- 18.7 [standard deviation]) disease underwent unenhanced CT. CT performed four detector rows, a...
Porto-sinusoidal vascular disorder (PSVD) is a recently defined liver disease. Since diagnosis remains challenging, we aimed to evaluate radiological features that are distinct between PSVD and cirrhosis.Clinical, laboratory, parameters (CT/MRI) of patients with histologically-confirmed vs. cirrhosis non-cirrhotic parenchymal disease were retrospectively evaluated.Sixty-three PSVD, 155 cirrhosis, 41 included. As compared younger had lower HVPG, stiffness, MELD. Routine clinical imaging...
Abstract Background and Aims Portal hypertension (PH) sarcopenia are common in patients with advanced chronic liver disease (ACLD). However, the interaction between PH their specific independent impact on prognosis mortality has yet to be systematically investigated ACLD. Methods Consecutive ACLD hepatic venous pressure gradient (HVPG) ≥10 mm Hg available CT/MRI imaging were included. Sarcopenia was defined by transversal psoas muscle thickness (TPMT) at <12 mm/m men <8 women level of...
Summary Background The use of mesenchymal stem cells is considered a novel and promising therapeutic option for patients with perianal fistulizing Crohn’s disease; however, data on its clinical application remain scarce. This multicenter nationwide study aimed to assess the efficacy in closing complex anal fistulas. Methods In this 14 disease (3 males, 11 females) fistulas treated 3 tertiary hospitals Austria were included between October 2018 April 2021. Injection 120 million allogeneic...
Abstract Oesophageal fluoroscopy is a radiological procedure that uses dynamic recording of the swallowing process to evaluate morphology and function simultaneously, characteristic not found in other clinical tests. It enables comprehensive evaluation entire upper gastrointestinal tract, from oropharynx oesophagogastric bolus transport. The number fluoroscopies oesophagus has increased recent decades, while overall use fluoroscopic examinations declined. Radiologists performing need good...
Abstract Background A primary objective in the management of Crohn's disease (CD) is prevention bowel tissue damage. The Lémann index (LI) characterizes structural damage based on magnetic resonance enterography (MRE) or computed tomography (CTE) and, for colonic CD, colonoscopy. Intestinal ultrasonography (IUS) provides a non-invasive imaging alternative, though its role LI assessment remains unexplored. This study aimed to establish consensus parameters and standardized acquisition scoring...
To assess the value of mangafodipir trisodium-enhanced MR imaging for characterization hepatocellular lesions.Magnetic resonance images 41 patients with 48 histopathologically proven lesions (20 cases focal nodular hyperplasia [FNH], 4 adenomas, 15 carcinomas [HCCs], 7 regenerative nodules, and 2 others) were retrospectively studied. Magnetic was performed on a 1.5-T unit (Vision, Siemens, Erlangen, Germany; ACS-NT, Philips, Best, The Netherlands) using T2-weighted, fat-saturation, turbo...
PURPOSE: To compare observer performance with a flat-panel liquid crystal display (LCD) monitor and high-resolution gray-scale cathode-ray tube (CRT) in the detection of simulated support catheters on bedside chest radiographs. MATERIALS AND METHODS: The ethics committee did not require approval or patient informed consent when this study began. Because change regulations, before images were acquired nature procedures explained to patients their relatives, was then obtained. A total 131...
To compare the results of a simultaneously performed videofluoroscopic swallowing study and fiberendoscopic evaluation in patients with dysphagia after surgery radiotherapy for oropharyngeal or laryngeal cancer. This prospective included 31 who were examined standardized protocol. The loops independently scored by two otorhinolaryngologists/phoniatricians radiologists. presence penetration/aspiration, amount pharyngeal residues position bolus head when triggering swallow begins evaluated....
Clinical assessment of swallowing disorders (dysphagia) requires accurate and comprehensive medical history-taking to further tailor the diagnostic work-up, but functional health care questionnaires show a large variability various limitations. The aim this study was assess way in which international experts from disciplines asses problems order improve radiologist´s ability take thorough history specific patient group. A two-step Delphi method used collect experts' ways taking patients with...
Abstract Objectives Videofluoroscopic swallowing studies (VFSS) remain the gold standard for instrumental assessment of oropharyngeal disorders alongside flexible endoscopic evaluation (FEES), requiring a high quality and correct implementation. The current best practice position statements aim to guide clinical VFSS in individuals experiencing disorders. Materials methods An international expert consensus panel with expertise dysphagia, comprised radiologists, speech-language therapists,...
