To evaluate the performance of non-contrast abbreviated MRI (NC-AMRI) with or without alpha foetoprotein (AFP) and dynamic abbreviated MRI (Dyn-AMRI) compared to complete MRI for hepatocellular carcinoma (HCC) detection in at-risk populations, specifically focusing on their comparative effectiveness.
Key Findings:
NC-AMRI demonstrated a sensitivity of 79.1% for HCC detection compared to 27.9% for ultrasound, highlighting its superior performance.
The addition of AFP to NC-AMRI showed improved performance in HCC screening, suggesting a synergistic effect.
Dyn-AMRI's performance data are still limited and require further evaluation to establish its role in clinical practice.
Interpretation:
The combination of NC-AMRI and AFP offers a promising alternative to traditional ultrasound for HCC surveillance, particularly in patients with advanced cirrhosis or large body habitus, potentially improving early detection rates.
Limitations:
The study is retrospective and conducted at a single center, which may limit generalizability and introduce selection bias.
Data on Dyn-AMRI performance is still scarce and requires further investigation to validate its effectiveness.
Conclusion:
NC-AMRI combined with AFP shows high performance for HCC screening, suggesting it could be a viable alternative to ultrasound in at-risk populations.
