Imaging Vascular Disorders of the Liver

Area of Science:

• Radiology
• Vascular Medicine
• Hepatology

Background:

• The liver possesses a unique dual blood supply crucial for its physiological functions.
• Disorders affecting the liver's vasculature can present with varied imaging findings, sometimes mimicking other diseases.
• Accurate diagnosis of hepatic vascular pathologies is essential for appropriate patient management.

Purpose of the Study:

• To review the multimodality imaging appearances of liver vascular disorders.
• To categorize these pathologies based on their impact on hepatic blood flow (inflow, outflow, arteriovenous connections).
• To enhance radiologists' ability to diagnose and manage liver vascular conditions.

Main Methods:

• Review of imaging findings from a multimodality perspective.
• Categorization of vascular pathologies based on hepatic blood flow dynamics.
• Discussion of the physiologic and pathologic basis of hepatic vasculature.

Main Results:

• Liver vascular disorders exhibit characteristic imaging patterns.
• Pathologies are systematically classified by their effect on liver inflow, outflow, and abnormal shunts.
• Understanding vascular physiology aids in differentiating these disorders.

Conclusions:

• A comprehensive understanding of hepatic vasculature and its disorders is vital for radiologists.
• Multimodality imaging review provides a robust approach to diagnosing liver vascular conditions.
• Radiologists play a key role in patient care through accurate interpretation of hepatic vascular imaging.
