To evaluate the clinical presentation and long-term outcome of a vasculitis centre cohort patients with microscopic polyangiitis (MPA) respect to organ manifestations, treatment, chronic damage mortality.We performed retrospective chart review at our referral centre. MPA admitted between 1991 2013 classified by modified European Medicines Agency algorithm were diagnosed treated according standardized interdisciplinary approach.Comprehensive data from workups was available for 144 (median...
Introduction: To investigate the feasibility of diffusion-weighted imaging (DWI) MRI for detecting pulmonary nodules at 1.5 Tesla in comparison with standard multidetector computed tomography (MDCT). Methods: Twenty patients disseminated cancer disease which MDCT had assured presence least one nodule were examined using a respiratory-gated DWI MR-sequence. Grey scale inverted source images and coronal maximum intensity projection (MIP) consensually analysed by two experienced radiologists....
Abstract Objectives To evaluate the feasibility and diagnostic performance of a 3D FRACTURE (fast field echo resembling CT using restricted echo-spacing) MRI sequence for detection classification proximal tibial fractures compared with CT. Methods We retrospectively included 126 patients (85 male; 39.6 ± 14.5 years) from two centers following acute knee injury. Patients underwent at 3 T including FRACTURE-MRI. Additional was performed in (32.5%; n = 41) as reference standard fracture...
Objective The goal of our study was to assess the prevalence osteoarthritis in knee joint active male professional soccer players by means semi-quantitative Whole-Organ Magnetic Resonance Imaging Score (WORMS). Design resonance imagings (MRIs) both knees were performed on 85 during their “medicals” (age = 24 ± 4 years). All baseline data (age, playing position) obtained. Based WORMS, status cartilage and bone medial lateral femoro-tibial (MFTJ LFTJ), as well patellofemoral assessed. Menisci...
To determine the image quality of an iterative reconstruction (IR) technique in low-dose MDCT (LDCT) chest immunocompromised patients intraindividual comparison to filtered back projection (FBP) and evaluate dose reduction capability.30 LDCT scans were performed (Brilliance iCT; 20-40 mAs; mean CTDIvol: 1.7 mGy). The raw data reconstructed using FBP IR (iDose4™, Philips, Best, Netherlands) set seven iteration levels. 30 routine-dose (RDCT) with served as controls (mean exposure: 116 CDTIvol:...
To define and compare growth rates of the distal aorta in Marfan patients with without aortic root replacement using serial MR angiography (MRA).We retrospectively included 136 a total 645 MRAs who underwent median five (range: 2-13) at 1.5 T 3 annual intervals. Of these, 41 (34.8 ± 12 years) had undergone replacement. The remaining 95 (29.0 17 still native served as control group. Thoracic diameters were independently measured eleven predefined levels. Estimated calculated mixed effects...
<h3>Objectives</h3> To investigate the correlation of serum levels high mobility group box 1 (HMGB1) with extent granulomatous inflammation in granulomatosis polyangiitis (GPA). <h3>Methods</h3> From 169 patients GPA, 17 inflammation, without evidence vasculitis were identified and 36 measurable 'granuloma' formation. HMGB1 determined compared between two groups, using a Mann–Whitney U test. Serum 26 healthy individuals served as controls. In further 21 GPA pulmonary manifestation from study...
Abstract Patellofemoral maltracking predisposes the patellofemoral joint to instability. The purpose of this study was provide a reliable dynamic magnetic resonance imaging (MRI) measuring technique for maltracking, and investigate influence anatomical risk factors (AF) on patellar maltracking. Ten patients (2 males,8 females, average 19 years) with clinical 20 controls (10 males,10 females,average 28 were examined dynamic, multi-slice gradient-echo MRI sequence, during repetitive...

Contrast-enhanced cardiovascular magnetic resonance angiography (CE-CMRA) is the established imaging modality for patients with Marfan syndrome requiring life-long annual aortic before and after root replacement. Contrast-free CMRA techniques avoiding side-effects of contrast media are highly desirable serial but have not been evaluated in postoperative setup patients. The purpose this study was to assess feasibility non-contrast balanced steady-state free precession (bSSFP) monitoring...
To quantitatively assess the immediate effect of long-distance running on T2 and T2* relaxation times articular cartilage knee at 3.0 T in young healthy adults.30 male adults (18-31 years) who perform sports an amateur level underwent initial MRI with weighted [16 echo (TEs): 9.7-154.6 ms] (24 TEs: 4.6-53.6 ms) measurements. Thereafter, all participants performed a 45-min run. After run, individuals were immediately re-examined. Data sets post-processed using dedicated software (ImageJ;...
Abstract Background The combined injury of the medial collateral ligament complex and anterior cruciate (ACL) is most common two knee. Additional injuries to capsuloligamentous structures are associated with rotational instability a high failure rate ACL reconstruction. study aimed analyze specific pattern their risk factors, goal enabling early diagnosis initiating appropriate therapeutic interventions, if necessary. Results Between January 2017 December 2018, 151 patients acute ruptures...
