Combined imaging improves accuracy for detecting liver metastases

Combining contrast-enhanced CT with MRI significantly boosts the detection of colorectal liver metastases, achieving sensitivity rates of 96.5% compared to 90.6% for MRI alone. Specificity also improved, from 95.3% to 98.3%. Notably, radiologists reported higher diagnostic confidence in 78.8% of cases with the combined approach, up from 64.7% with MRI alone. Additionally, inter-observer agreement reached an “almost perfect” level when using both imaging modalities, indicating substantial enhancements in diagnostic performance.
