Diffusion weighted magnetic resonance imaging in assessment of hepatocellular carcinoma after chemoembolization
Conclusions MRI DWI offers quick and non-invasive technique to distinct between viable and necrotic tumor areas and helps the diagnosis of residual tumor. Potential effect of treatment can be detected as increase in the diffusion coefficient. We recommend that optimal follow-up after image guided trans-catheter tumor therapy should include DWI and contrast-enhanced MRI.
Conclusion: Intraprocedural fusion imaging combining CEUS and auto sweep three-dimensional US appears to be a useful modality for RFA guidance and evaluation of therapeutic efficacy of RFA in patients with HCC. PMID: 32070164 [PubMed - in process]
To assess the role of pretreatment tumor radiomic features in predicting pathologic response in patients with hepatocellular carcinoma (HCC) listed for liver transplant.
To assess the impact of muscle mass on survival in patients with hepatocellular carcinoma undergoing yttrium-90 radioembolization.
Contrast-enhanced ultrasound (CEUS) is a low cost and effective imaging modality that is accessible immediately post procedure which allows the clinician to instantly perform additional ablation of the tumor if a residual tumor is detected. CEUS can be an alternative to contrast enhanced CT in patients with underlying renal disease or iodine allergy. The purpose of this abstract is to share our experience with use of contrast enhanced ultrasound after microwave ablation for HCC with MRI correlation and posttransplant pathology.
The purpose of this study was to apply automatic machine learning on routine pre procedure MR to predict treatment response of patients with hepatocellular carcinoma (HCC) following transcatheter arterial chemoembolization (TACE).
Conclusion: Planning, targeting, and controlling of RFA were well supported by MRI with acceptable time. MRI-guided RFA for small HCCs in the hepatic dome is safe and effective with fewer RF sessions. PMID: 32066293 [PubMed - in process]
AbstractGadoxetic acid-enhanced magnetic resonance imaging (MRI) plays important roles in diagnosis of hepatic lesions because of its superiority in the detectability of small lesions, its differentiation ability, and its utility for the early diagnosis of hepatocellular carcinoma (HCC). In HCC, expression of organic anion transporting polypeptide (OATP) 1B3 correlates with the enhancement ratio in the hepatobiliary phase. Gadoxetic acid-enhanced MRI, an indirect molecular imaging method, reflects OATP1B3 expression in HCC. OATP1B3 expression gradually decreases from the dysplastic nodule stage to advanced HCC. Decreased e...
ConclusionsFFMA as a measure of sarcopenia predicts OS and might represent a promising new biomarker for survival prognosis in patients undergoing RE for treatment of unresectable HCC.
CONCLUSION: Liver nodules should be characterised with regard to underlying liver condition, MRI characteristics and contrast enhancement pattern, including hepatobiliary phase. In many cases, identification of fatty content may help narrowing the differential diagnosis. PMID: 32008550 [PubMed - in process]
AbstractDuring routine ultrasound examination, a hyperechoic mass was detected in the anterior segment of the liver in an 80-year-old woman with hepatitis C virus-related cirrhosis. Computed tomography and magnetic resonance imaging findings suggested a malignant tumor with abundant fibrous stroma, similar to cholangiolocellular carcinoma. However, subsequent partial hepatectomy revealed a mass characterized by abundant fibrosis without tumor cells, dilated blood vessels, and marginal ductular reaction. Accordingly, focal confluent fibrosis was diagnosed. Generally, the diagnosis of focal confluent fibrosis is straightforw...
