We compared the diagnostic performance of gadoxetic acid-enhanced MRI with that triple-phase 16-, 40-, and 64-MDCT in preoperative detection hepatocellular carcinoma (HCC).Sixty-two consecutively registered patients (54 men, eight women; age range, 31-67 years) 83 HCCs underwent (arterial, portal venous, equilibrium) CT at or 3-T MRI. The diagnosis HCC was established after surgical resection. Three observers independently randomly reviewed MR images on a tumor-by-tumor basis. accuracy these...
Objective: We compared surgical resection (SR) and radiofrequency ablation (RFA) as first-line treatment in patients with hepatocellular carcinoma (HCC) based on the risk of microvascular invasion (MVI). Background: The best curative modality between SR RFA HCC MVI remains unclear. Methods: Data from 2 academic cancer center-based cohorts a single, small (≤3 cm) who underwent were used to derive (n = 276) validate 101) prediction models for using clinical imaging variables. model was...
The Minimal Ablative Margin of Radiofrequency Ablation Hepatocellular Carcinoma (> 2 and < 5 cm) Needed to Prevent Local Tumor Progression: 3D Quantitative Assessment Using CT Image FusionYoung-sun Kim1, Won Jae Lee, Hyunchul Rhim, Hyo K. Lim, Dongil Choi Ji Young LeeAudio Available | Share
Although radio-frequency (RF) ablation has been accepted as a promising and safe technique for treatment of unresectable hepatic tumors, investigation its complications limited. According to the multicenter (1,139 patients in 11 institutions) survey data Korean Study Group Radiofrequency Ablation, spectrum occurred after RF tumors. The prevalence major was 2.43%. most common were abscess (0.66%), peritoneal hemorrhage (0.46%), biloma (0.20%), ground pad burn pneumothorax vasovagal reflex...
The purpose of this study was to evaluate the usefulness color Doppler sonography in differentiating benign from malignant cervical lymphadenopathy.We used 117 lymph nodes 105 patients. patients were pathologically and clinically confirmed have reactive lymphadenitis (n = 28), tuberculosis 17), lymphoma 14), metastasis 46). patterns hilar vascularity, central nodal peripheral vascularity assessed. highest resistive index pulsatility 116 measured spectral waveforms. Histologic findings...
To compare the efficacy of radiofrequency ablation (RFA) and surgical resection in a group patients with Child-Pugh score 5 single HCC less than 4 cm diameter.Radiofrequency has become popular method for treatment hepatocellular carcinoma (HCC) been applied as an alternative primary therapy to resection.We compared outcomes 148 treated RFA (n = 55) those surgically 93).The rate local recurrence among was significantly higher surgery (P 0.005), while incidence remote similar between two...
The diagnosis of acute appendicitis in pregnant women often is difficult to make on the basis clinical findings, and radiologic examination limited because potentially hazardous effects radiation. This study was done assess value sonography women.We obtained sonograms 45 with clinically suspected appendicitis. Our sonographic technique included graded-compression scanning. left lateral decubitus position used third trimester gestation. criterion for visualization an incompressible appendix a...
Purpose To compare radiofrequency (RF) ablation with nonanatomic resection (NAR) as first-line treatment in patients a single Barcelona Clinic Liver Cancer (BCLC) stage 0 or A hepatocellular carcinoma (HCC) and to evaluate the long-term outcomes of both therapies. Materials Methods This retrospective study was approved by institutional review board. The requirement for informed consent waived. Data were reviewed from 580 HCCs measuring 3 cm smaller (BCLC A) who underwent ultrasonographically...
To evaluate the frequency, risk factors, and clinical significance of aggressive intrasegmental recurrence (AIR) found after radiofrequency (RF) ablation for hepatocellular carcinoma (HCC).Institutional review board approval was obtained this retrospective study. Between March 2005 December 2010, 539 patients (414 men, 125 women; mean age, 57.91 years; age range, 30-82 years) underwent ultrasonography-guided percutaneous RF as a first-line treatment single HCC classified Barcelona Clinic...
Accurate assessment of the degree liver fibrosis is important for estimating prognosis and deciding on an appropriate course treatment cases chronic disease (CLD) with various etiologies. Because inherent limitations biopsy, there a great need non-invasive reliable tests that accurately estimate fibrosis. Ultrasound (US) elastography considered non-invasive, convenient, precise technique to grade by measuring stiffness. There are several commercial types US currently in use, namely,...
The purpose of this study was to determine whether fusion imaging-guided percutaneous radiofrequency ablation (RFA) is effective in the management hepatocellular carcinoma (HCC) that has poor conspicuity at conventional sonography.Percutaneous RFA HCC with performed under imaging guidance. time needed for image between ultrasound and CT or MR images recorded. quality degree operator confidence identifying index tumor were graded on 4-point scales. Technical success procedure-related...
Purpose To compare the long-term therapeutic outcomes of radiofrequency (RF) ablation for hepatocellular carcinoma (HCC) in subcapsular versus nonsubcapsular locations by using propensity score matching. Materials and Methods RF HCC is controversial because a high risk incomplete or major complications. This retrospective study was approved institutional review board, requirement informed consent waived. Between April 2006 December 2011, 508 consecutive patients (396 men, 112 women; age...
Given the complexity of managing hepatocellular carcinoma (HCC), a multidisciplinary approach (MDT) is recommended to optimize management HCC patients. However, evidence suggesting that MDT improves patient outcome limited.We performed retrospective cohort study all patients newly-diagnosed with between 2005 and 2013 (n = 6,619). The overall survival (OS) rates who were not managed via compared in entire 6,619), exactly matched 1,396).In cohort, 5-year rate was significantly higher (71.2%...
OBJECTIVE. Our objective was to assess the feasibility, safety, and efficacy of percutaneous radiofrequency ablation with artificial ascites for hepatocellular carcinoma (HCC) in hepatic dome.
PURPOSE: To assess the diagnostic usefulness of ultrasonography (US) in intussusception children and determine whether color Doppler sonography (CDS) can indicate bowel viability help prediction reducibility. MATERIALS AND METHODS: US was used to examine 176 whom presence clinically suspected. CDS performed 64 patients with 65 cases proved US. RESULTS: The positive findings were confirmed air enema; negative findings, enema 46 clinical follow-up 66 (100% specificity sensitivity). indicated...
