PURPOSE: To retrospectively evaluate the accuracy of magnetic resonance (MR) arthrography in classification anteroinferior labroligamentous injuries by using arthroscopy as reference standard. MATERIALS AND METHODS: Ethical committee approval and informed consent were obtained. MR arthrograms obtained 205 patients, including a study group 104 patients (74 male 30 female; mean age, 28.2 years) with arthroscopically proved control 101 (65 36 31.4 intact complex, reviewed random order. analyzed...
The purpose of this study was to compare the value respiration-triggered diffusion-weighted (DW) single-shot echo-planar MRI (EPI) and five variants T2-weighted turbo spin-echo (TSE) sequences in diagnosis hepatic metastasis.Fifty-two patients with extrahepatic primary malignant tumors underwent 1.5-T that included DW EPI following TSE techniques: breath-hold fat-suppressed HASTE, fat-supressed TSE, STIR, STIR. Images were reviewed independently by two blinded observers who used a 5-point...
Background An artificial intelligence model that assesses primary bone tumors on radiographs may assist in the diagnostic workflow. Purpose To develop a multitask deep learning (DL) for simultaneous bounding box placement, segmentation, and classification of radiographs. Materials Methods This retrospective study analyzed acquired prior to treatment obtained from patient data January 2000 June 2020. Benign or malignant were diagnosed all patients by using histopathologic findings as...
Abstract Objectives To evaluate the performance of 3D T1w spoiled gradient-echo (T1SGRE) and ultra-short echo time (UTE) MRI sequences for detection assessment vertebral fractures degenerative bone changes compared with conventional CT. Methods Fractures ( n = 44) 60 spinal segments) were evaluated in 30 patients (65 ± 14 years, 18 women) on CT 3-T MRI, including CT-like images derived from T1SGRE UTE. Two radiologists morphological features both modalities: Genant AO/Magerl classifications,...

To retrospectively determine the diagnostic accuracy of magnetic resonance (MR) arthrography shoulder in evaluation lesions biceps pulley and to evaluate previously described new signs.Institutional review board approval was obtained; requirement for informed consent waived. MR arthrograms 80 consecutive patients (mean age, 34.2 years; 53 male, 27 female) with arthroscopically proved intact or torn systems were assessed presence a lesion by three radiologists who blinded arthroscopic...
The aim of the study was to evaluate functional and radiological outcome following derotational distal femoral osteotomy (D-DFO) in patients with high-grade patellofemoral instability (PFI) an associated increased antetorsion (FA). It hypothesized that D-DFO would lead a good outcome, both torsional coronal malalignment could be normalized.Patients underwent between 06/2011 12/2018 for PFI FA (> 20°) were included. Patient-reported measures (Visual Analog Scale [VAS] pain, Kujala score,...
To evaluate a compressed sensing artificial intelligence framework (CSAI) to accelerate MRI acquisition of the ankle.Thirty patients were scanned at 3T. Axial T2-w, coronal T1-w, and coronal/sagittal intermediate-w scans with fat saturation acquired using only (12:44 min, CS), CSAI an acceleration factor 4.6-5.3 (6:45 CSAI2x), 6.9-7.7 (4:46 CSAI3x). Moreover, high-resolution axial T2-w scan was obtained similar duration compared CS. Depiction presence abnormalities graded. Signal-to-noise...
To evaluate the diagnostic performance of an automated reconstruction algorithm combining MR imaging acquired using compressed SENSE (CS) with deep learning (DL) in order to reconstruct denoised high-quality images from undersampled patients shoulder pain.Prospectively, thirty-eight (14 women, mean age 40.0 ± 15.2 years) pain underwent morphological MRI a pseudo-random, density-weighted k-space scheme acceleration factor 2.5 CS only. An DL-based (CS DL) was used create reconstructions same...
Effective treatment of osteochondral lesions in the elbow remains challenging. Arthroscopic débridement and microfracture or retrograde drilling techniques are often insufficient provide only temporary symptomatic relief. The purpose this study was to evaluate these with autografts.From 1999 2002, seven patients capitellum humeri (five patients), trochlea (one patient), radial head patient) were treated cylindrical grafts, which harvested from non-weight-bearing area proximal aspect lateral...
Background: In the long-term follow-up after debridement, microfracture, or drilling of osteochondral lesions in elbow, subsequent osteoarthritis is a problem. Osteochondral transplantation for these defects has become more common procedure. However, results are unknown. Purpose: This study was undertaken to evaluate clinical and radiologic outcomes advanced elbow treated with transplantation. Study Design: Case series; Level evidence, 4. Methods: The included 8 patients who were by...
