Summary
Ultrasonography and CT scans are initial tools for diagnosing liver tumors. Advanced imaging like CT angiography and MRI offer detailed assessment, guiding surgical and interventional treatments for liver cancers and other lesions.
Area of Science:
- Radiology
- Medical Imaging
- Hepatology
Background:
- Liver tumors require accurate diagnosis and staging.
- Various imaging modalities are used for hepatic lesion evaluation.
Purpose of the Study:
- To outline the role of different imaging techniques in diagnosing and managing hepatic tumors.
- To describe the applications of ultrasonography, CT, MRI, and angiography in liver disease.
Main Methods:
- Initial work-up involves ultrasonography with colour Doppler.
- Dual-phase spiral CT is used for characterization and extent assessment.
- CT angiography (CTA) and CT arterial portography (CTAP) offer precise imaging.
- Magnetic Resonance Imaging (MRI) aids in diffuse liver disease and focal lesion evaluation.
Main Results:
- Combined CT and angiography provide the most precise imaging for vascular mapping and pre-surgical planning.
- Angiography is crucial for therapeutic interventions, including transarterial embolization.
- Percutaneous and angiographic techniques effectively treat inoperable hepatocellular carcinoma (HCC), metastases, and hemangiomas.
Conclusions:
- Imaging selection depends on the clinical indication, from initial diagnosis to complex interventional procedures.
- Multimodality imaging is essential for comprehensive liver tumor management.
- Interventional radiology offers effective treatment options for unresectable liver tumors.
