In a time-independent test set from a new retrospective study, gadoxetic-acid enhanced MRI provided nearly 38 percent higher sensitivity for detecting sub-centimeter hepatocellular carcinoma recurrence (HCC) in contrast to extracellular contrast agent-enhanced MRI.

For patients with cardiac dysfunction related to neoadjuvant chemotherapy for invasive breast cancer, new MRI research shows increased risks for concurrent decreases in total brain volume and white matter volume.

There was no statistically significant difference in sensitivity rates for lesion detection between breast MRI scans with minimum or mild background parenchymal enhancement (BPE) and those with moderate or marked BPE, according to a newly published study involving over 300 women.
