Acute Hepatic Necrosis - LiverTox - NCBI Bookshelf
May 4, 2019 · The clinical course of acute hepatic necrosis resembles an acute, toxic injury to the liver with sudden and precipitous onset, marked elevations in serum aminotransferase levels, and early signs of hepatic (or other organ) dysfunction or failure despite minimal or no jaundice.
Bleeding Liver Masses: Imaging Features With Pathologic ... - AJR
Apr 11, 2019 · A broad spectrum of pathologic conditions can present as spontaneous hemorrhage within or surrounding the liver and may present acutely or as a chronic or incidental finding. Imaging characteristics and clinical history can often narrow the differential diagnosis and guide management.
CT and MRI of Cirrhosis and its Mimics - AJR
The combination of nodularity, fibrosis, and segmental volume changes may make distinguishing hepatic necrosis from cirrhosis difficult; however, one clue may be that in hepatic necrosis, vessels may traverse necrotic lesions without displacement (Fig. 7A, 7B, 7C). Intraoperatively, differentiation of hepatic necrosis with regeneration from ...
MR imaging in liver cirrhosis: classical and new approaches
Aug 5, 2010 · To be clinically useful, any method used to evaluate chronic hepatitis and cirrhosis must accurately identify regeneration, inflammation, necrosis, fibrosis, fat, iron and also neoplasia. Fibrosis, necroinflammatory activity, fat and iron deposits are the most important parameters for antiviral treatment indication and follow-up.
Cirrhosis | Radiology Reference Article | Radiopaedia.org
Jun 2, 2024 · Cirrhosis (plural: cirrhoses) is the common endpoint of a wide variety of chronic liver disease processes which cause hepatocellular necrosis. Cirrhosis can be diagnosed with ultrasound, CT, and MRI, and these imaging modalities can also be used to evaluate for possible complications of cirrhosis, such as portal hypertension or hepatocellular ...
Interpretation of CT and MRI After Radiofrequency Ablation of Hepatic …
The characteristic MRI signals of coagulation necrosis after radiofrequency ablation are intermediate to high signal-to-liver parenchyma on T1-weighted and low signal on T2-weighted images. A T2 hyperintense rim around the ablation area is a possible finding, likely related to edema from thermal injury.
Spectrum of liver lesions hyperintense on hepatobiliary phase: an ...
Hepatobiliary MRI contrast agents are increasingly being used for liver imaging. In clinical practice, most focal liver lesions do not uptake hepatobiliary contrast agents. Less commonly, hepatic lesions may show variable signal characteristics on hepatobiliary phase.
Liver Imaging - StatPearls - NCBI Bookshelf
Feb 20, 2023 · Liver ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) are the primary imaging modalities to diagnose liver lesions. Postcontrast imaging can help distinguish lesions depending on their degree of vascularity and composition.
Liver Masses: A Clinical, Radiological and Pathological Perspective For ...
The radiologic features of liver masses as assessed by liver ultrasonography (US) or by cross-sectional imaging using computed tomography (CT) or magnetic resonance imaging (MRI) are extremely helpful in diagnosis.
MR imaging in liver cirrhosis: classical and new approaches
The typical histological features of chronic hepatitis and cirrhosis are variable degrees of hepatocellular necrosis and inflammation (activity or grade of disease), fibrosis (stage of disease), and associated fat and iron deposition.
