Importance Given the widespread use of medical imaging, evaluating effectiveness interventions to improve appropriateness is crucial for optimizing health care resources and patient outcomes. Objective To assess effects implementing a clinical decision support system (CDSS), European Society Radiology iGuide, on imaging ordering behavior physicians. Design Setting A cluster randomized trial with 26 departments at 3 German university hospitals acting as clusters, incorporating before after...
<h3>BACKGROUND AND PURPOSE:</h3> Signal intensity increases possibly suggestive of gadolinium retention have recently been reported on unenhanced T1-weighted images the pediatric brain following multiple exposures to gadolinium-based MR contrast agents. Our aim was determine whether T1 signal changes deposition occur in brains nonneurologic patients after gadobenate dimeglumine. <h3>MATERIALS METHODS:</h3> Thirty-four (group 1; 17 males/17 females; mean age, 7.18 years) who received between...
To establish a standardized scoring system for angiographic findings in patients with non-occlusive mesenteric ischemia (NOMI).In 36 (mean age: 72 years), 53 angiographies of the superior artery (SMA) were performed suspected NOMI after cardiac or major aortic surgery. All examinations using DSA technique. Two experienced radiologists consensus reading blinded to clinical information, on two occasions an interval weeks. In order investigate reproducibility criteria, images assessed once by...
Abstract Background Computed tomography (CT) is the standard procedure for follow-up of non-small-cell lung cancer (NSCLC) after radiochemotherapy. CT has difficulties differentiating between tumor, atelectasis and radiation induced toxicity (RILT). Diffusion-weighted imaging (DWI) may enable a more accurate detection vital tumor tissue. The aim this study was to determine diagnostic value MRI versus in NSCLC. Methods Twelve patients with NSCLC stages I-III scheduled radiochemotherapy were...
A critical problem in cardiovascular MRI small rodents is adjusting the sequence acquisition to high heart and respiratory rates. The aim of this study was compare a retrospectively self-gated fast low angle shot navigator (RSG-FLASH) with conventional prospectively triggered (PT-FLASH) for cine imaging ascending aorta mice at 9.4 T.Ten C57/BL6 were examined horizontal bore Tesla animal scanner using dedicated 2 × phased-array surface coil. We acquired RSG-FLASH (RSG-FLASH sequences...
The study was designed to evaluate diffusion-weighted magnetic resonance imaging (DWI) vs. PET-CT of the thorax in determination gross tumor volume (GTV) radiotherapy planning non-small-cell lung cancer (NSCLC).Eligible patients with NSCLC who were supposed receive definitive radio(chemo)therapy prospectively recruited. For MRI, a respiratory gated T2-weighted sequence axial orientation and non-gated DWI (b = 0, 800, 1,400 apparent diffusion coefficient map [ADC]) acquired on 1.5 Tesla...
The purpose of this study was to prospectively compare the effect inspiration and resting expiratory position on contrast enhancement in pulmonary CT angiography (CTA) a randomized clinical trial.In accordance with power analysis performed before study, we included 28 consecutive patients referred for evaluation suspected embolism prospective study. Patients were randomly assigned perform either (n = 14; six men, eight women; mean age [SD], 38.1 ± 9.8 years) or age: 42.1 9.2 years). All...
Apolipoprotein E-deficient (ApoE−/−) rodents spontaneously develop severe hypercholesterolemia and increased aortic stiffness, both accepted risk factors for cardiovascular morbidity mortality in humans. In patients with resistant hypertension renal denervation (RDN) may improve arterial however the underlying mechanisms are incompletely understood. This study investigates impact of RDN on compliance a novel atherosclerosis prone ApoE−/−-rat model. Normotensive, 8 weeks old ApoE−/−...

Objectives: To prospectively evaluate the relationship of established inflammatory markers and presepsin on nonocclusive mesenteric ischemia to correlate levels occurrence severity ischemia. Design: Patients were enrolled blood samples taken, followed by a retrospective evaluation laboratory values angiographic findings. The study was ethics committee approved. Settings: with clinical suspicion underwent catheter angiography superior artery. Images assessed two experienced radiologists...
Purpose Accurate detection of central venous catheter (CVC) misplacement is crucial for patient safety and effective treatment. Existing artificial intelligence (AI) often grapple with the limitations label inaccuracies output interpretations that lack clinician-friendly comprehensibility. This study aims to introduce an approach employs segmentation support material anatomy enhance precision comprehensibility CVC detection. Materials Methods The utilized 2 datasets: publicly accessible...
To evaluate low-dose gadobenate dimeglumine-enhanced MRI for the differential diagnosis of malignant renal tumors.Sixty-two consecutive patients with unclear at MDCT/ultrasound underwent dynamic CE-MRI kidneys 0.05 mmol/kg dimeglumine. Retrospective image evaluation was performed by two blinded readers. Lesion correlated findings from histology following tumor resection or imaging follow-up after least 1 year. Assessments were diagnostic quality and level information.Thirty-nine (63 %)...
Abstract For students, early hands-on experience is very limited and often non-existent during study time. Thus, we aimed to evaluate the progress of inexperienced medical students in successfully establishing an ultrasound-guided vessel access. One brief, condensed single teaching lesson a prior post-teaching scenario was performed using inexpensive, self-made phantom model. In this prospective study, ( n = 11) with no ultrasound imaging access simulated by gelatin-based Success rates time...
Abstract Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare but potentially curable cause of (PH). Currently PH diagnosed by right heart catheterisation. Computed tomography (CT) used for ruling out other causes and operative planning. This study aims to evaluate importance different quantitative/qualitative imaging features develop supervised machine learning (ML) model predict hemodynamic risk groups. 127 Patients with CTEPH who received preoperative catheterization thoracic...
The best surgical treatment option for symptomatic moderate- to high-grade articular-sided partial-thickness rotator cuff tears (PTRCTs) is still controversial.The purpose of this study was evaluate patient-reported and clinical outcomes tendon integrity after arthroscopic debridement or repair PTRCTs at a minimum 2 years postoperatively. We hypothesized that the overall would be positive, showing pain relief, good shoulder function, high integrity.Cohort study; Level evidence, 3.We...
Purpose To evaluate the value of preoperatively assessed fibroblast growth factor 23 (FGF-23) levels and to correlate FGF-23 with angiographic findings in non-occlusive mesenteric (NOMI) ischemia using a standardized scoring system. Materials methods Between 2/2011 3/2012 total 865 patients (median age: 67 years) underwent cardiovascular surgery during this ethics committee approved, prospective study. 65 these had clinical suspicion NOMI consequently catheter angiography superior artery....
