OBJECTIVE. The objective of our study was to compare the quality and diagnostic utility following three metal artifact reduction sequences in evaluating hip arthroplasties: conventional multiacquisition variable-resonance image combination selective (MAVRIC SL), isotropic MAVRIC SL, reduced-TR SL. SUBJECTS AND METHODS. Ninety-three arthroplasties (85 total replacements eight resurfacings [nine bilateral hips]) 84 patients (38 men 46 women; mean age ± SD, 69.1 9.7 years old) were imaged...
Background Because loosening of total knee arthroplasty (TKA) occurs due to poor osseous integration at component-bone interfaces, interface assessment may be helpful in diagnosing MRI. Purpose To determine interreader reproducibility for characterizing component interfaces and evaluate the diagnostic performance MRI after TKA compared with radiography. Materials Methods Consecutive knees that underwent revision between July 2018 June 2019 were imaged radiography included this retrospective...
Microvascular invasion (MVI) of small hepatocellular carcinoma (sHCC) (≤ 3.0 cm) is an independent prognostic factor for poor progression-free and overall survival. Radiomics can help extract imaging information associated with tumor pathophysiology.To develop validate radiomics scores a nomogram gadolinium ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance (MRI) preoperative prediction MVI in sHCC.In total, 415 patients were diagnosed sHCC by...
Abstract Context Many individuals at high risk for osteoporosis and fragility fracture are never screened by traditional methods. Opportunistic use of imaging obtained other clinical purposes is required to foster identification these patients. Objective The aim this pilot study was evaluate texture features as a measure bone fragility, comparing clinically acquired magnetic resonance (MRI) scans from with without history fracture. Methods This retrospectively investigated 100 subjects who...
Abstract Background Implant loosening is a common cause of reoperation after THA. Plain radiographs have been the default modality to evaluate loosening, although provide relatively insensitive assessment integration; cross-sectional modalities may more detailed evaluation but traditionally suffered from metal-related artifacts. We sought determine whether MRI capable reliably detecting operatively confirmed component in patients hip arthroplasty. Questions/purposes (1) Is assessing implant...
Background Oblique sagittal MRI sequences, orthogonal to the longitudinal axis of brachial plexus, can reliably depict morphologic and signal abnormalities. However, nerve visualization may be obscured by ghosting artifact from periodic respiratory motion. Respiratory triggering (RT) with a thoracoabdominal bellows reduce artifact, but it is not routinely used for plexus MRI. Furthermore, efficacy prospective RT imaging has yet been reported. Purpose To compare sequences acquired without...
Previous studies have utilized ultrashort echo (UTE) magnetic resonance imaging (MRI), and derived T2* maps, to evaluate structures with highly ordered collagen such as tendon. maps may provide a noninvasive means assess tendon damage healing. This pilot study evaluated the longitudinal relationship of an induced mechanical strain on patellar corresponding UTE metrics, histologic biomechanical evaluation at two post-operative time points.A total 27 tendons in male Beagles were surgically...
BackgroundThe ability to utilize magnetic resonance imaging (MRI) assess bony fixation in 3 dimensions may allow a better understanding of the implant design and integration. We hypothesized that new 3-dimensionally printed cementless highly porous acetabular component (Stryker Trident II TritaniumTM) would show than an earlier cup from same manufacturer as assessed by noninvasive technique multispectral MRI.MethodsMultiacquisition variable-resonance image combination selective metal...
Background: Hip arthroplasty is increasingly prevalent, and early detection of complications can improve outcomes. Quantitative magnetic resonance imaging (qMRI) methods using multi-acquisition variable-resonance image combination (MAVRIC) may allow for the assessment soft tissues in close proximity to hip devices. Question/Purposes: We sought determine clinical feasibility MAVRIC-based T2 mapping as a qMRI approach assessing synovial reactions patients with device. hypothesized that there...
Abstract Background The evaluation of the natural history prevalence adverse local tissue reactions (ALTRs) using MRI has focused only on metal-on-metal (MoM) bearing surfaces without comparison to nonMoM surfaces. Questions/purposes To determine (1) longitudinal changes and differences in blood metal ion levels patients with hip resurfacing arthroplasty (HRA), ceramic-on-ceramic (CoC) THA, metal-on-polyethylene (MoP) THA compared those undergoing ceramic-on-polyethylene (CoP) THA; (2) how...
The purpose of this study was to investigate the incidence and causes non-fusion segment disease (NFSD), both adjacent non-adjacent a fused segment, after anterior cervical arthrodesis.This is single-center study. Between January 1998 2011, two surgeons' 171 patients who had an decompression fusion were followed clinically for more than 5 years. correlation between symptomatic following clinical parameters (age at operation, levels,) radiological (number plate, (ACDF) or corpectomies,...
To develop and validate a radiomic nomogram for individualized prediction of hepatocellular carcinoma (HCC) in HBV cirrhosis patients based on baseline magnetic resonance imaging examinations clinical data.364 with from five hospitals were assigned to the training, internal validation, external validation-1 or validation-2 cohort. All underwent image (MRI) scans follow-up within three-year time. Clinical risk factors MRI-based features extracted analyzed. The signatures built using...
As a non-invasive method, positron emission tomography (PET)/computed (CT) using 2-deoxy-2-fluoro-18-fluoro-D-glucose (18F-FDG) is applied as useful modality in the diagnosis of breast cancer. By evaluating glucose metabolism, this method can also be used staging, restaging and post-therapeutic response evaluation. To evaluate reliability 18F-FDG PET/CT-based peri-tumoral halo uptake layer (PHL) for assessing tumor size, total 79 female patients with cancer who underwent PET/CT, ultrasound...
Summary Background Few noninvasive methods are available for equine hoof wall evaluation. The highly organised structures and composition of proteoglycans collagens may make this region amenable to quantitative MRI (qMRI) techniques T1ρ T2 mapping identify pathology related proteoglycan content collagen organisation respectively. Objective To establish normative values the 3‐year‐old Quarter Horses with histological comparison. Study design Cadaveric anatomical study. Methods Six cadaveric...
Abstract Objective: To assess a new deep learning-based MR reconstruction method, “DLRecon,” for clinical evaluation of peripheral nerves. Methods: Sixty nerves were prospectively evaluated in 29 patients (mean age: 49±16 years, 17 female) undergoing standard-of-care (SOC) neurography clinically suspected neuropathy. SOC-MRIs and DLRecon-MRIs obtained through conventional DLRecon methods, respectively. Two radiologists randomly blinded images outer epineurium conspicuity, fascicular...

Methods 31 cases who underwent scan head due to trauma were selected from October 2015 December 2nd hospital Shanxi medical university. The image was obtained as observation group, and contrast routine control group. Date effective dose(ED) quality score recorded compared using self-control study. Results The ED group less than which reduced...
