Identification of the factors associated with improved facial nerve function after treatment Bell palsy is important to provide patients early and effective treatment.To identify that are outcomes in palsy.This retrospective cohort study included 1364 treated at outpatient clinic Department Otolaryngology Kyung Hee University Hospital, Seoul, Republic Korea, between January 1, 2005, December 31, 2017. The medical records admitted this hospital for management acute were reviewed by 3...
Quantification of abdominal muscle mass by cross-sectional imaging has been increasingly used to diagnose sarcopenia; however, the technical method for quantification not standardized yet. We aimed determine an optimal measure area.Among 50 consecutive subjects who underwent CT and MRI possible liver donation, total area (TAMA) psoas (TPA) at L3 inferior endplate level were measured two blinded readers. Inter-scan agreement between inter-reader readers evaluated using intraclass correlation...
Background Deep learning (DL) may facilitate the diagnosis of various pancreatic lesions at imaging. Purpose To develop and validate a DL-based approach for automatic identification patients with solid cystic neoplasms abdominal CT compare its diagnostic performance that radiologists. Materials Methods In this retrospective study, three-dimensional nnU-Net–based DL model was trained using data who underwent resection between January 2014 March 2015 subset without abnormality in 2014....
Background Noninvasive diagnostic guidelines for hepatocellular carcinoma (HCC) vary across different global geographic areas, especially regarding criteria about gadoxetic acid-enhanced MRI. Purpose To compare the performance of four international HCC diagnosis and readers' judgment in diagnosing using MRI patients at high risk HCC. Materials Methods This retrospective study included who had not undergone treatment, were HCC, underwent from January 2015 to June 2018 11 tertiary hospitals...
T1 relaxation time is a tissue-specific parameter that correlates with liver fibrosis, and can be valuable tool for detecting staging of disease. However, affected by histological factors such as fat, so it necessary to study the effects hepatic steatosis when assessing function fibrosis. The purpose this investigate fat separation effect mapping using Dixon watermap Look-Locker inversion recovery (LLIR) in assessment on gadoxetic acid (GA)-enhanced magnetic resonance imaging (MRI). A total...
Background Complex‐based chemical shift imaging‐based magnetic resonance imaging (CSE‐MRI) is emerging as a preferred method for noninvasively quantifying proton density fat fraction (PDFF), promising quantitative biomarker (QIB) longitudinal hepatic steatosis measurement. Purpose To determine linearity, bias, repeatability, and reproducibility of the PDFF measurement using CSE‐MRI (CSE‐PDFF) across scan intervals, MR field strengths, readers in phantom nonalcoholic fatty liver disease...
To evaluate the reliability of CT measurements muscle quantity and quality using variable parameters.A phantom, simulating L2-4 vertebral levels, was used for this study. images were repeatedly acquired with modulation tube voltage, current, slice thickness, image reconstruction algorithm. Reference standard compartments obtained from reference maps phantom. Cross-sectional area based on Hounsfield unit (HU) thresholds its components, mean density compartment, to measure different protocols....
This study aimed to develop a convolutional neural network (CNN) using the EfficientNet algorithm for automated classification of acute appendicitis, diverticulitis, and normal appendix evaluate its diagnostic performance. We retrospectively enrolled 715 patients who underwent contrast-enhanced abdominopelvic computed tomography (CT). Of these, 246 had 254 215 appendix. Training, validation, test data were obtained from 4,078 CT images (1,959 823 1,296 cases) both single serial (RGB [red,...
Objective The aim of this study was to investigate whether ultrasound elastography can demonstrate the outcome treatment in comparison with gray-scale imaging. Methods Sixteen patients (mean age, 46.9 years) plantar fasciitis were prospectively enrolled after unsuccessful conservative treatment. Individuals graded their heel pain on a 100-mm visual analogue scale (VAS) and underwent ultrasonography sonoelastography. Collagen injected heels. Fascial thickness hypoechogenicity, perifascial...
Objectives: To analyze serial changes in body composition and investigate the association between disease activity patients with Crohn’s (CD). Methods: Seventy-one CD who had been treated followed-up at our institution were included. Two to four computed tomography images acquired baseline, 2−5-year, 5−8-year, last follow-ups selected per patient for analyses. Visceral fat area (VFA), skeletal muscle index (SMI; area/height2), subcutaneous (SFA) assessed using an...
To analyze the correlation between intestinal ultrasound (IUS) and serum fecal biomarkers, characteristics of small bowel disease, for assessment active inflammation.Patients with Crohn's disease (CD) who underwent an initial IUS examination July 2018 November 2022 at our institution were included retrospectively. We divided large bowels into seven segments, recorded presence inflammation according to following criteria: wall thickness ≥ mm ≥1 feature on IUS. The correlations IUS-assessed...
The role of imaging is crucial for the surveillance, diagnosis, staging and treatment monitoring hepatocellular carcinoma (HCC). Over past few years, considerable technical advances were made in HCCs. New technology, however, has introduced new challenges our clinical practice. In this article, current status techniques HCC addressed. diagnostic performance context recent guidelines also presented. Keywords: Hepatocellular carcinoma; Diagnostic imaging; Ultrasonography; Computed tomography;...
Abstract Rationale: Rheumatoid arthritis (RA) shows a variable clinical expression in patients. Articular disease is common manifestation, but patients may rarely present with extra-articular manifestation such as cranial neuropathy. Also, primary hepatic lymphoma (PHL) has been reported patient treated immunosuppressive drug methotrexate (MTX) for RA. We herein describe case of neuropathy and MTX-related PHL woman receiving MTX Patient concerns: A 73-year-old women received treatment more...
