To evaluate renal allografts function early after transplantation using intravoxel incoherent motion (IVIM) and arterial spin labeling (ASL) MRI. This prospective study was approved by the local ethics committee, written informed consent obtained from all participants. A total of 82 participants with 62 allograft recipients (2–4 weeks kidney transplantation) 20 volunteers were enrolled to be scanned IVIM ASL MRI on a 3.0 T MR scanner. Recipients divided into two groups either normal or...
Objective: To investigate white matter microstructure and spontaneous cerebral activity in early neurosyphilis using tract-based spatial statistics amplitude of low-frequency fluctuation (ALFF). Methods: Twenty patients with 20 matched healthy controls underwent diffusion tensor imaging resting-state blood oxygen level-dependent imaging. Neuropsychological tests were performed before each magnetic resonance Fractional anisotropy (FA), mean diffusivity (MD), ALFF values compared between the 2...
Objective: To investigate the liver T1rho values for detecting fibrosis, and potential impact of fatty on measurements.Materials Methods: This study included 18 healthy subjects, patients with liver, who underwent MRI mDIXON collections.Liver T1rho, proton density fat fraction (PDFF) T2* were measured compared among three groups.Receiver operating characteristic (ROC) curve analysis was performed to evaluate fibrosis.Liver correlated PDFF, clinical data.Results: Liver PDFF significantly...
The present study compares the efficacy of a self-expanding metallic stent (SEMS, diameter 30 mm) and pneumatic dilation for long-term clinical treatment achalasia. A total 155 patients diagnosed with achalasia were allocated (n= 80, group A) or temporary, 30-mm SEMS 75, B). SEMSs placed under fluoroscopic guidance removed by gastroscopy 4-5 days after placement. Data on symptoms, complications, outcomes collected, follow-up observations performed at 6 months 1, 3-5, 5-8, 8-10, >10 years,...
To describe the multiparametric magnetic resonance imaging (MRI) appearance of prostate tuberculosis.Six patients with tuberculosis were analyzed retrospectively. The mean age was 60.5 years (range, 48-67 years). specific antigen concentration 6.62 ng/mL 0.54-14.57 ng/mL). All underwent a MRI examination.The histopathological results obtained from biopsies in four men and transurethral resection two after examination. Nodular (33%, 2/6 patients) diffuse lesions (67%, 4/6 seen on MRI. nodular...
Background Although improvement of cognitive function after liver transplantation has been demonstrated in several neuropsychological studies, there is limited research on longitudinal changes the cirrhotic patients' brain structure before and transplantation. Purpose To investigate microstructure patients using diffusion kurtosis imaging (DKI). Study Type Prospective. Subjects A total 153 cirrhosis patients, comprising 60 hepatic encephalopathy (HE) (16 females/44 males) 93 no‐HE (35...
<b>Background and study aims:</b> The aim of the current was to assess whether placement biodegradable rapamycin-eluting nano-fiber membrane-covered metal stent is followed by less fibroblast proliferation tissue hyperplasia compared with bare stents in experimental stricture a dog model. <b>Methods: </b>A total 80 models were randomly divided into control group (n = 20, no insertion), (BSG, n 1-week retention), two drug-eluting sub-groups (DESG-1w, retention; DESG-4w, 4-week retention)....
To investigate the merit of T1rho relaxation for evaluation liver fibrosis, inflammatory activity, and injury monitoring in a carbon tetrachloride (CCl4)-induced rat model.Model rats from CCl4-induced fibrosis (fibrosis group: n = 41; regression 20) control (n 11) groups underwent black blood magnetic resonance (MR) imaging (MRI). Injection CCl4 was done twice weekly up to 12 weeks group 6 group. MR scanning time points were at baseline 2, 4, 6, 8, 10 after injection (CCl4 withdrawal), 7,...
The study aimed to evaluate the contributions of levator ani muscle (LAM) injury, vesical neck movement, urethral length and mobility, sphincter dysfunction observed on magnetic resonance imaging (MRI) towards stress urinary incontinence (SUI) after vaginal delivery.Fifty primiparous women 6 months delivery (15 with SUI 35 without) nulliparous as continent controls underwent MRI at rest Valsalva maneuver. A published scoring system was used characterize morphological changes LAM. severity...
To evaluate the spontaneous brain activity alterations in liver transplantation (LT) recipients using resting-state functional MRI. Twenty cirrhotic patients as transplant candidates and 25 healthy controls (HCs) were included this study. All repeated MRI study one month after LT. Amplitude of low-frequency fluctuation (ALFF) values compared between (both pre- post-LT) HCs well post-LT groups. The relationship ALFF changes venous blood ammonia levels neuropsychological tests investigated...
<h3>BACKGROUND AND PURPOSE:</h3> The detailed mechanisms of cerebral aneurysm generation remain unclear. Our aim was to investigate whether specific hemodynamic insult in combination with arterial wall degeneration leads the development aneurysms a canine model. <h3>MATERIALS METHODS:</h3> New branch points common carotid artery were created 18 dogs. Nine animals subsequently received elastase at bifurcation apex (elastase-treated group); control group (<i>n</i> = 9) saline, and 3 dogs an...
Abstract Objective To explore the efficiency, cost, and time for examination of one‐stop‐shop gadoxetic acid disodium ( G d‐ EOB ‐ DTPA )‐enhanced magnetic resonance imaging MRI ) in preoperative evaluation parent donors by comparing with multidetector computer tomography combined conventional MR cholangiopancreatography MDCT MRCP ).

Hepatic encephalopathy (HE) is a neurocognitive dysfunction based on metabolic disorders caused by severe liver disease, which has high one-year mortality. Mild hepatic (MHE) risk of converting to overt HE, and thus the accurate identification MHE from cirrhosis with no HE (noHE) great significance in reducing Previously, most studies focused studying abnormality static brain networks find biomarkers. In this study, we aimed use multi-layer modular algorithm study dynamic graph properties...
Structural and metabolic abnormalities in the hippocampus have been associated with pathophysiological mechanism of central nervous system involvement primary Sjögren syndrome (pSS). Nevertheless, how hippocampal function is altered pSS remains unknown. The purpose our study to investigate alterations functional connectivity (FC) by using resting-state magnetic resonance imaging (rs-fMRI). Thirty-eight patients 38 age- education level-matched healthy controls (HCs) underwent examination....
