Why does contrast enhancement occur rapidly in the liver compared to other organs after intravenous administration?
Why does contrast enhancement occur rapidly in the liver compared to other organs after intravenous administration?
- The liver has a higher concentration of interstitial space.
- The liver has a lower metabolic rate.
- The liver has a unique dual blood supply. (correct)
- Contrast agents are specifically absorbed by liver cells.

Flashcards
Triphasic Liver CT Scan
Triphasic Liver CT Scan
A CT scan using contrast to assess liver lesions, hypervascular liver metastases, and endocrine tumors.
Indications for Triphasic Liver CT
Indications for Triphasic Liver CT
Useful for identifying suspected liver lesions like hepatocellular carcinoma and hemangioma.
Hepatic Contrast Enhancement
Hepatic Contrast Enhancement
Contrast agent is rapidly redistributed from blood vessels to the interstitial space and excreted by kidneys, occurring rapidly in the liver due to its dual blood supply.
Study Notes
- Triphasic liver CT scans are useful for assessing focal liver lesions, hypervascular liver metastases, and endocrine tumors.
- This scan can aid in the diagnosis of suspected liver lesions like hepatocellular carcinoma, focal nodular hyperplasia, adenoma, and hemangioma.
- When contrast agent is administered intravenously, it rapidly redistributes from the vascular to the interstitial space while being continuously excreted by the kidneys.
- This process occurs rapidly in the liver due to its unique dual blood supply.
