Summary
Triple-phase computed tomography (CT) accurately distinguishes benign from malignant indeterminate focal liver lesions (FLLs). This imaging technique aids in better clinical decisions for liver lesion management.
Area of Science:
- Radiology
- Medical Imaging
- Hepatology
Background:
- Indeterminate focal liver lesions (FLLs) pose diagnostic challenges.
- Management varies based on whether FLLs are benign or malignant.
Purpose of the Study:
- To evaluate the diagnostic performance of triple-phase multidetector computed tomography (MDCT) for characterizing indeterminate FLLs.
- To assess dynamic contrast enhancement patterns in liver lesions.
Main Methods:
- Utilized triple-phase MDCT, analyzing contrast enhancement in arterial, portal venous, and delayed phases.
- Assessed vascular and enhancement patterns to differentiate lesion types.
Main Results:
- Triple-phase CT accurately differentiated benign from malignant FLLs.
- Malignant lesions showed distinct features like portal venous hypoenhancement and late-phase washout.
- Enhancement patterns provided key diagnostic insights.
Conclusions:
- Triple-phase CT demonstrates high accuracy in managing indeterminate FLLs.
- This imaging modality supports improved clinical decision-making for liver lesions.
