Summary
Arteriography is effective for diagnosing large hepatocellular carcinoma. Advanced techniques improve detection of small tumors, aiding in staging and differentiating lesions in cirrhotic livers.
Area of Science:
- Radiology
- Hepatology
- Oncology
Background:
- Hepatocellular carcinoma (HCC) diagnosis relies on imaging.
- Arteriography is a key diagnostic tool for HCC.
Purpose of the Study:
- To evaluate the diagnostic role and sensitivity of arteriography in identifying hepatocellular carcinoma.
- To assess advanced arteriographic techniques for small HCC detection.
- To explore arteriography's utility in characterizing neoplastic lesions and preoperative staging.
Main Methods:
- Review of arteriography's diagnostic performance in HCC detection.
- Comparison of standard angiography with advanced techniques like CT arteriography and CT arterial portography.
- Assessment of specificity in differentiating HCC from adenomatous hyperplastic nodules.
- Evaluation of arteriography for identifying satellite lesions and vascular invasion.
Main Results:
- Angiography shows 100% sensitivity for large HCC (>3-5 cm).
- Sensitivity for small HCC is 82-89%, improved to 91-95% with CT arteriography and CT arterial portography.
- Specificity in differentiating HCC from hyperplastic nodules is 72%.
- Angiography aids in detecting satellite lesions and vascular invasion for staging.
Conclusions:
- Arteriography is valuable for HCC diagnosis, especially large lesions.
- Advanced techniques significantly enhance the detection of small HCC.
- Angiography plays a role in lesion characterization and preoperative staging of HCC.
