Abstract Purpose To determine the efficacy of combined use magnetic resonance (MR) imaging, MR cholangiography (MRC), and angiography (MRA) in preoperative evaluation gallbladder carcinoma. Materials Methods During a 20‐month period, 41 patients with proven carcinomas were referred for examination, including MRC, gadolinium‐enhanced dual‐phase MRA to operability their Eighteen who underwent surgery within six days examination included this study. All images analyzed order assess bile duct...
The objective of our study was to determine significant CT findings for the differentiation biliary cystic neoplasms from simple hepatic cysts and assess whether radiologists' performance is improved with knowledge criteria.Review surgical pathologic records identified 25 patients pathologically proven (biliary cystadenomas [n = 8], cystadenocarcinomas 4]) or 13]). Two radiologists retrospectively reviewed images in consensus location, size, outer margin lesion presence an internal septum,...
Abstract Purpose To evaluate the diagnostic accuracy of MRI for predicting circumferential resection margin (CRM), mesorectal fascia (MRF) invasion, and tumor response to neoadjuvant chemoradiotherapy (CRT) locally advanced rectal cancer. Materials Methods Sixty‐five consecutive patients with cancer (≥T3 or lymph node‐positive) who underwent CRT subsequent surgery were enrolled in this retrospective study. Two blinded radiologists independently reviewed both pre‐ post‐CRT MR images measured...
Recent advances in computed tomographic (CT) technology, three-dimensional imaging software, and cheaper data storage capacity have made faster, simpler, more accurate gastric available. Two-dimensional multiplanar reformation CT gastrography including virtual gastroscopy transparency rendering allow cross-sectional imaging, gastroscopic viewing, upper gastrointestinal series the same acquisition. Multi-detector row allows noninvasive assessment of wall perigastric extent disease. It is also...
This retrospective study was institutional review board approved; the requirement for informed patient consent waived. The purpose of this to retrospectively compare a two-dimensional (2D) data interpretation technique with three-dimensional (3D) colon dissection in terms time and sensitivity colonic polyp detection, colonoscopy as reference standard. Ninety-six patients (56 men, 40 women; mean age, 54.8 years) underwent multidetector computed tomographic (CT) colonography on same day. Two...
Purpose The purpose of this study is to compare the sensitivity computed tomography (CT) colonography (CTC) with that colonoscopy for detecting patients colorectal polyps in an asymptomatic screening population Korea, thus evaluate a possibility, whether CTC could be used as tool polyps. Methods A total 241 adults underwent intravenous contrast-enhanced and successively on same day. Bowel preparation was performed by 4 L polyethylene glycol (n=172) or 90 mL sodium phosphate (n=69). findings...
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...

The purpose of our study was to evaluate the usefulness contrast-enhanced sonography for prostate cancer detection in patients with an indeterminate prostate-specific antigen (PSA) level (4-10 ng/mL) and negative findings on digital rectal examination.Forty-eight underwent gray-scale, color Doppler, examinations then sonographically guided biopsy. Contrast-enhanced performed using Levovist at a mechanical index 1.1-1.4. performances three methods were compared according biopsy site...
The purpose of this study was to assess the diagnostic accuracy MDCT for determining prognostic factors, including T category, lymph node metastasis, tumor size, and perineural invasion, in surgically proven intraductal papillary mucinous neoplasms (IPMNs) with an associated invasive carcinoma (IPMC) investigate imaging findings.Our group consisted 38 patients IPMC who underwent preoperative dynamic CT. Two radiologists retrospectively assessed morphologic type IPMN, size cyst, main...
Tumor stage, node metastasis, tumor size, vascular invasion, and perineural invasion are the most important prognostic factors that might be determined by preoperative multidetector computed tomography (MDCT) in pancreatic cancer. The purpose of our study is to investigate diagnostic accuracy MDCT for determining these factors.For 6 years, 111 patients with surgically resected cancer underwent MDCT. Two radiologists retrospectively assessed invasion. They also graded using a 3-point scale...
Coded harmonic angio (CHA) US is a recently developed technique that can depict the effects of contrast agents. The purpose this study was to determine role in depicting enhancement patterns various renal perfusion abnormalities compared with dynamic CT.During 6-month period, lesions including cell carcinoma (n=12), transitional (n=5), acute pyelonephritis and trauma (n=2) were evaluated CHA using microbubble agent. images obtained before administration bolus injection 4 g agent (300 mg/ml)...
Purpose: To evaluate the accuracy of CT for staging gallbladder cancers, especially T-factor TNM system. Material and Methods: investigations 100 patients with surgically proven cancers were retrospectively analyzed. Dynamic helical was performed in 16 conventional remaining 84. On CT, three radiologists attempted tumor these patients; majority opinion used final decision. According to protocols (dynamic vs. CT) each type (thickened wall/intraluminal mass/massive), compared. The correlated...
