Summary
Computed tomography (CT) and magnetic resonance imaging (MRI) reveal characteristic features of hepatic angiosarcoma, including indistinct borders, heterogeneous density, and frequent hemorrhage. Enhanced imaging shows centripetal heterogeneous enhancement, aiding diagnosis.
Area of Science:
- Radiology
- Oncology
- Hepatology
Background:
- Hepatic angiosarcoma is a rare and aggressive primary liver cancer.
- Accurate imaging is crucial for diagnosis and treatment planning.
Purpose of the Study:
- To analyze the computed tomography (CT) and magnetic resonance imaging (MRI) manifestations of hepatic angiosarcoma.
- To identify characteristic imaging features that aid in the diagnosis of hepatic angiosarcoma.
Main Methods:
- Retrospective analysis of 19 patients with hepatic angiosarcoma.
- Preoperative abdominal unenhanced and contrast-enhanced CT or MRI were performed.
- Coagulation examination results were reviewed.
Main Results:
- Coagulation abnormalities were present in 63.16% of patients.
- Unenhanced CT showed hypointense lesions with hyperintense hemorrhage.
- Contrast-enhanced CT/MRI revealed centripetal heterogeneous enhancement.
- MRI showed heterogeneous intensity, with hemorrhage appearing hyperintense on T2WI.
Conclusions:
- CT and MRI present characteristic features of hepatic angiosarcoma.
- Key findings include indistinct borders, heterogeneous density, hemorrhage, and centripetal enhancement.
- Highly malignant tumors may not enhance.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

01:08Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment
274
Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...
