Abstract Purpose To evaluate the usefulness of wash‐in rate based on dynamic contrast‐enhanced (DCE) MRI for detection and localization prostate cancer. Materials Methods In 53 patients, was measured in cancer area three normal areas (the peripheral zone, inner portion transitional outer zone). On basis these data, parametric imaging generated then its accuracy location evaluated compared to that T2‐weighted without use an endorectal coil. For purpose entire divided into 18 segments. Results...
Despite improvements in treatment modalities, gastric cancer is the second cause of mortality among Korean men and third females Korea. Korea implemented a screening program for general population 1999. However, effectiveness harms using endoscopy upper gastrointestinal (UGI) series have not been fully evaluated. In an effort to evaluate program, multidisciplinary expert committee developing guideline systematically reviewed evidence regarding benefits screening, developed evidence-based...
The aim of this study was to investigate the diagnostic accuracy contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) small renal masses in real practice. Contrast-enhanced CT MRI were performed between February 2008 2013 on 68 patients who had suspected (≤4 cm) cell carcinoma (RCC) based ultrasonographic measurements. radiographs reviewed, findings re-categorized into five dichotomized scales by same two radiologists interpreted original images. Receiver operating...
Pediatric breast disease is uncommon, and primary carcinoma in children extremely rare. Therefore, the approach used to address lesions pediatric patients differs from that adults many ways. Knowledge of normal imaging features at various stages development characteristics population can help radiologist make confident diagnoses manage appropriately. Most diseases are benign or associated with development, suggesting a need for conservative treatment. Interventional procedures might affect...
Our objective is to show the various clinical applications of MDCT enterography for evaluating small-bowel disease, with a focus on added value 3D imaging.MDCT and refined imaging processes can offer full examination small bowel as well powerful information about its surrounding structures.
The study was conducted, with institutional review board approval and informed patient consent, to assess the feasibility diagnostic effectiveness of three-dimensional direct multi-detector row computed tomographic (CT) cholangiography for determining extent bile duct invasion by hilar cholangiocarcinoma. Eleven patients underwent contrast material-enhanced CT primary secondary biliary confluence levels then surgical resection. In most patients, tolerable yielded excellent or good...
Objective: To evaluate the safety and technical success rate of an ultrasound-guided fiducial marker implantation in preparation for CyberKnife radiation therapy. Materials Methods:We retrospectively reviewed 270 percutaneous implantations 77 patients, which were performed from June 2008 through March 2011.Of implantations, 104 implanted metastatic lymph nodes, 96 liver, 39 pancreas, 31 prostate.During after implantation, major minor procedure-related complications documented.We defined as...
Ultrasonography (renamed from the Journal of Korean Society Ultrasound in Medicine January 2014), official English-language journal (KSUM), is an international peer-reviewed academic dedicated to practice, research, technology, and education dealing with medical ultrasound, Aims Scope:Ultrasonography ultrasound.It published four times per year: 1, April July October 1. Original articles, topical reviews, pictorial essays, notable case reports are covering state-of-the-art content. also...
This study assessed the reproducibility and clinical value of vascular index (VI), derived from superb microvascular imaging (SMI) using Doppler ultrasonography, for evaluating renal function in transplanted kidneys. retrospective included 63 transplant patients who underwent grayscale ultrasonography with SMI January 2022 to February 2023. The VI kidneys was measured three methods (VIbox, VIF1, VIF2). compared across chronic kidney disease (CKD) groups categorized by estimated glomerular...
The objective of our study was to assess the diagnostic performance virtual gastroscopy using MDCT for detection early gastric cancer (EGC) compared with 2D axial CT, focusing on interobserver reliability.During an 11-month period, we performed CT examinations 94 consecutive patients EGC and a control group composed 68 without EGC. Three radiologists retrospectively interpreted images. Diagnostic performances were within each observer area under receiver operating characteristic curve...
Case ReportAcute phlegmonous infection of the gastrointestinal tract is characterized by purulent inflammation submucosa and muscular layer with sparing mucosa.The authors report a rare case acute diffuse esophagogastritis, which was well diagnosed based on typical chest computed tomographic (CT) findings successfully treated.A 48-yr-old man presented left pain dyspnea for three days.Chest radiograph admission showed mediastinal widening bilateral pleural effusion.The patient became febrile...
Diffusion-weighted imaging (DWI) with reduced field-of-view (FOV) has been shown to provide high spatial resolution distorsion in the spinal cord, breast, pancreas, and prostate gland. Therefore, we performed this study evaluate qualitative image quality quantitative ADC value of FOV DWI patients cervical cancer comparison conventional DWI.This retrospectively included 22 (mean age, 53.9 years) biopsy-proven who underwent pelvic MR including before therapy. Two observers independently rated...
Human herpesvirus 8 (HHV-8)-associated primary effusion lymphoma is a rare non-Hodgkin’s often associated with Epstein-Barr virus (EBV) infection. Mutations in TP53, PTEN, PIK3CA, CTNNB1/β-catenin genes and deletion of CDKN2A-ARF (p14ARF-p16NK4a I ) locus were investigated sixteen tumors seven cell lines using PCR sequencing. TP53 mutations detected one tumor (6.2%) two (28.6%). BC-3 BCP-1 showed PTEN gene mutations, loss protein expression both cases. No PIK3CA hotspot sequences. Only...
