Non-enhanced abbreviated MRI outperforms contrast-enhanced CT for liver metastases detection

In a prospective study involving 587 colorectal cancer patients, non-enhanced abbreviated MRI (ne-amri) demonstrated superior diagnostic accuracy for liver metastases detection compared to contrast-enhanced CT (ce-ct). Across three surveillance rounds, ne-amri consistently showed higher lesion-based detection rates and better patient-based metrics, including sensitivity and specificity. Notably, it outperformed ce-ct even for lesions ≤ 10 mm. This method presents a promising, non-invasive alternative that can refine clinical management while reducing exposure to radiation and contrast agents.
