Classic Imaging Signs in Hepatobiliary Radiology: A Multimodality Review

Area of Science:

• Radiology
• Medical Imaging
• Hepatology

Background:

• Classic radiological signs are crucial visual clues in medical imaging.
• These signs aid in differential diagnosis and increase diagnostic confidence.
• Hepatic pathology presents diverse conditions requiring accurate interpretation.

Purpose of the Study:

• To review key imaging signs in hepatic pathology.
• To discuss the pathophysiology, diagnostic utility, and clinical relevance of these signs.
• To reinforce pattern recognition skills for radiologists in hepatic imaging.

Main Methods:

• Review of characteristic imaging signs in hepatic pathology.
• Inclusion of multiple imaging modalities: ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI).
• Exploration of neoplastic, infectious, vascular, and miscellaneous hepatic conditions.

Main Results:

• Identified characteristic imaging signs for various hepatic pathologies.
• Discussed the diagnostic utility and clinical relevance of each sign.
• Highlighted the importance of these signs in narrowing differential diagnoses.

Conclusions:

• Revisiting classic radiological signs enhances radiologists' pattern recognition abilities.
• This review serves as a practical reference for hepatic imaging interpretation.
• Accurate interpretation of hepatic imaging signs is essential for patient management.
