BACKGROUND. Shoulder MRI using standard multiplanar sequences requires long scan times. Accelerated have tradeoffs in noise and resolution. Deep learning-based reconstruction (DLR) may allow reduced time with preserved image quality. OBJECTIVE. The purpose of this study was to compare shoulder accelerated without DLR terms quality diagnostic performance. METHODS. This retrospective included 105 patients (45 men, 60 women; mean age, 57.6 ± 10.9 [SD] years) who underwent a total 110 3-T...
The purpose of this study was to evaluate whether the strain ratio provides additional value conventional visual elasticity scores in differentiation benign and malignant soft tissue tumors by ultrasonic elastography.The Institutional Review Board approved protocol retrospective review. Seventy-three patients who underwent elastography had a mass pathologically confirmed ultrasound-guided core biopsy or surgical excision were enrolled from April 2012 through October 2014. On elastography,...
Comparison of the Effectiveness Embolic Agents for Bronchial Artery Embolization: Gelfoam versus Polyvinyl AlcoholObjective: The purpose this study was to compare results different agents bronchial artery embolization hemoptysis. Materials and Methods:From March 1992 December 2006, a performed on 430 patients with hemoptysis.The were divided into three groups.Group 1 included 74 treated gelfoam particle (1×1×1 mm), while group 2 comprised 205 polyvinyl alcohol (PVA) at 355-500 μ m, 3 151 PVA...
To compare the diagnostic performance of modified Dixon (mDixon) turbo spin echo (TSE) T2 weighted MRI and conventional T1 in vertebral metastasis detection.Between September 2014 October 2016, 33 patients with 68 metastases who had undergone whole-spine were enrolled. The following sagittal image sets evaluated: T1WI, mDixon TSE water fat images. Two radiologists independently evaluated each image-set for metastasis. MR findings compared positron emission tomography-CT (PET-CT) scans....
Objectives To compare the diagnostic performance between strain elastography and shear wave (SWE) for diagnosis of carpal tunnel syndrome (CTS). Methods Between July 2018 June 2019, 66 consecutive patients with 95 imaged wrists underwent wrist ultrasound, including grayscale elastography, SWE, because suspicion CTS. During cross‐sectional area (CSA), ratio, elasticity, velocity each median nerve were measured at proximal bone level (scaphoid to pisiform). The variables compared normal CTS...
Background: Recurrence after percutaneous ethanol ablation (PEA) of benign hepatic and renal cysts has been common, resulting in re-treatment or additional surgery. However, recent years, a few cases spontaneous regression recurrent following PEA have experienced, which led to the design this study evaluate cyst recurrence necessity treatment. Purpose: To whether initial hepatic, renal, splenic is true recurrence, decide treatment needed. Material Methods: Thirty-nine (21 17 one splenic)...
Background Structural lesion evaluation in axial spondyloarthropathy (SpA) can improve accuracy of diagnosis. However, structural lesions (bone erosions) are difficult to be assessed using conventional MRI compared computed tomography (CT). Purpose To evaluate the diagnostic performance ultrashort echo time (UTE) for detecting bone erosion SpA T1WI and three‐dimensional double‐echo steady‐state (3D DESS) imaging CT as reference standard. Study Type Retrospective. Population Fourteen patients...
Background and PurposezzHyperkalemic periodic paralysis (hyperKPP) is a muscle sodium-ion channelopathy characterized by recurrent paralytic attacks.A proportion of affected individuals develop fixed or chronic progressive weakness that results in significant disability.However, little known about the pathology hyperKPP-induced weakness, including pattern involvement.The aim this study was to characterize patterns involvement hyperKPP whole-body magnetic resonance imaging (MRI).MethodszzWe...
Purpose: To compare short tau inversion recovery (STIR) images with slice encoding for metal artifact correction (SEMAC)-corrected magnetic resonance imaging (MRI) of spectral presaturation (SPIR) or (IR) at 3T in patients metallic spinal instrumentation.
This study aimed to compare the diagnostic performance of gray-scale ultrasound (GSU), strain elastography (SE), and shear wave (SWE) for lateral epicondylitis (LE).From November 2018 March 2021, 87 common extensor tendons (CETs) 70 patients were evaluated using elbow ultrasound. Patients divided into two groups: with LE those without pain. GSU, SE, SWE findings from groups compared, was compared significant variables.Among patients, 41 44 CETs clinically diagnosed LE, 29 43 had no...
FK506 is a newly developed potent immunosuppressant for preventing rejection after organ transplantation. However, can induce central nervous system toxicity. Until now the pathogenic mechanism of neurotoxicity was unclear. We report findings diffusion-weighted MRI and apparent diffusion coefficient (ADC) mapping patient who showed increased signal intensities in both parieto-occipital lobes on T 2 weighted images, images ADC maps. These suggest that vasogenic oedema rather than cytotoxic...
Background Conventionally, two-dimensional (2D) fast spin-echo (FSE) sequences have been widely used for clinical cartilage imaging as well gradient (GRE) sequences. Recently, three-dimensional (3D) volumetric magnetic resonance (MRI) has introduced with one 3D scan, and this is replacing slice-by-slice 2D MR scans. Purpose To evaluate the image quality diagnostic performance of two abnormalities knee cartilage: fat-suppressed (FS) FSE-based volume isotropic turbo acquisition (VISTA)...
Abstract We aim to evaluate the performance of a deep convolutional neural network (DCNN) in predicting presence or absence sarcopenia using shear-wave elastography (SWE) and gray-scale ultrasonography (GSU) rectus femoris muscle as an imaging biomarker. This retrospective study included 160 pair sets GSU SWE images (n = 160) from December 2018 July 2019. Two radiologists scored echogenicity on (4-point score). Among them, 141 patients underwent CT their L3 skeletal index (SMI) were measured...
Abstract Purpose We aim to evaluate the shear wave velocity (SWV) of thenar muscle as an adjunct diagnostic tool for carpal tunnel syndrome (CTS). Methods Ninety‐two wrists with CTS and 30 control without underwent ultrasonographic evaluation median nerve including shear‐wave elastography. Cross sectional area (CSA) medial SWV were evaluated. patients assessed Boston CTS, Padua modified Hirani grading scores, conduction study (NCS). SWVs, CSA, NCS parameters compared between two groups....
Subpial hemorrhage (SPH) is a subtype of intracranial characterized by damage to the adjacent brain parenchyma. The aim this study was describe sonographic features SPH in neonates.The cranial ultrasound (US) findings neonates with confirmed magnetic resonance imaging (MRI) were analyzed retrospectively.
