The purpose of this article is to assess the value computer-aided diagnosis (CAD) for prostate cancer detection on dynamic contrast-enhanced MRI (DCE-MRI).DCE-MRI examinations 42 patients with were used generate perfusion parameters, including baseline and peak signal intensities, initial slope, maximum slope within 50 seconds after contrast injection (slope(50)), wash-in rate, washout time peak, percentage relative enhancement, enhancement ratio, arrival, efflux rate constant from...
The aim of this study was to assess the risk liver fibrosis in those with no glucose intolerance, prediabetes, or diabetes. A cross-sectional conducted based on a cohort from health examination program which included magnetic resonance elastography (MRE). Participants were classified into three groups according tolerance: and diabetes mellitus. Liver evaluated by stiffness measurement (LSM) value using two-dimensional real-time MRE. significant compared among groups. total 2,090 subjects...
We report here a case of pathologically proven solitary fibrous tumor the pancreas. A 54-year-old man was referred to our hospital for further evaluation pancreatic mass that found incidentally. CT, MR imaging, and endoscopic ultrasonography showed well-defined, enhancing with cystic portions pancreas body. cholangiopancreatography no duct dilatation. is very rare lesion.
Study Design. This was a radiologic validity and reliability study. Objective. We aimed to assess the of measurements from standing lateral cervical radiography (XR), reconstructed midsagittal images supine computerized tomography (CT) scans, magnetic resonance imaging (MRI) for evaluating C2–C7 distance (C27 SVA), Cobb angle (CL), T1 slope (T1S), thoracic inlet (TIA), neck tilt (NT). Summary Background Data. XR is criterion standard modality measuring sagittal alignment parameters. However,...
Summary Background Significant hepatic fibrosis is associated with higher mortality. However, data on the estimated prevalence of liver in general population are scarce. Aim To use magnetic resonance elastography (MRE) to investigate a Korean health check‐up clinic cohort. Methods We enrolled 2170 participants at our between January 2015 and May 2018, all whom had MR chemical shift technique MRE. The primary objective was estimate fibrosis. For generalisation, sex‐ age‐standardised...
Purpose Angiographic finding including venous drainage pattern should be correlated to the presenting symptom (SxP) in CSDAVF. We present outcome of CSDAVF management and suggest a strategy according SxP type treatment based on our experience. Materials Methods evaluated SxP, angiographic (proliferative, restrictive or late restrictive), mode (embolization, Gamma Knife Radiation (GKR) conservative management), embolization (transarterial transvenous), final clinical status (cure,...
Quantitative magnetic resonance imaging (MRI) of cartilage has recently been applied to patients with osteoarthritis (OA). T2 mapping is a sensitive method detecting changes in the chemical composition and structure cartilage.To establish baseline values glenohumeral joint at 3.0 T compare among subjects without OA.The study involved 30 (18 women, 12 men; median age, 67 years; age range, 51-78 years) primary (n = 7) secondary OA 23) 34 (19 15 49 23-63 years). All were evaluated by...
Objective To identify preoperative computed tomography (CT) predictors associated with conversion from laparoscopic to open cholecystectomy and propose the risk scoring model for prediction of by integrating clinical, laboratory, CT parameters. Methods The institutional review board approved this retrospective study, informed consent was waived. One hundred eighty-three patients who underwent a acute cholecystitis were evaluated Associations between these parameters assessed using univariate...
The accurate estimation of liver volume and right/left ratio in donor candidates is critical, but there no method using portal vein (PV) flow.Of 125 candidates, was estimated ultrasound (US)-PV area Doppler US-PV flow ratio, the results were compared with CT volumetry. We analyzed these 76 donors who underwent hemihepatectomy. evaluated diagnostic values for <30% remnant high-risk donors, by actual graft weight.In 96.8% showed <10% difference between Compared volumetry, mean percentage...
Aims: To compare the accuracy of ultrasound attenuation index (USAI) and hepato-renal (HRI) for diagnosis hepatic steatosis (HS). Material methods: Two hundred twenty-four potential living donors underwent US subsequent US-guided liver biopsy. The USAI was calculated from images with an 8 MHz transducer HRI measured on sagittal a clear visualization both kidney. Using histological degrees HS as reference standard, we compared performance diagnosing ≥ 5% 30% by receiver operating...
In brain magnetic resonance imaging (MRI), white matter hyperintensity (WMH) is a commonly encountered finding and known to reflect cerebral small vessel disease. The aim of our study was investigate the association coronary artery calcium (CAC) with WMH elucidate relationship between atherosclerotic risk factors in large-scale healthy population. This retrospective included 1337 individuals who underwent MRI CAC scoring computed tomography at healthcare centers affiliated tertiary hospital....
Objectives To assess the value of ultrasound (US) attenuation index for noninvasive estimation hepatic steatosis and determine its optimal cutoff severe in potential living liver donors. Methods Two hundred forty donors underwent US-guided biopsy. The target site was scanned at 4 8 MHz. On sonogram, observer drew 3 × 3-mm square regions interest superficial (3-cm) deep (5-cm) areas. defined as difference between echogenicity/superficial echogenicity 100. biopsy specimens, replacement...

To evaluate the diagnostic performance of ultrasound and to determine which findings are useful differentiate appendicitis from non-appendicitis in patients who underwent re-evaluation owing equivocal CT features acute appendicitis.
Exploiting ultrashort-TE (UTE) MRI, T1-weighted positive contrast can be obtained from superparamagnetic iron oxide nanoparticles (SPIONs), which are widely used as a robust T2-weighted, negative agent on conventional MR images. Our study was designed (a) to optimize the dual-contrast MRI method using SPIONs and (b) validate feasibility of simultaneously evaluating vascular morphology, blood volume transvascular permeability effect SPIONs. All studies were conducted 3 T MRI. According...
