[ Summary ] |
Contrast-enhanced three-dimensional MR angiography (CE-3D-MRA) is a promising method for evaluating patients with cirrhotic liver because it allows us to simultaneously obtain both arterial and portal-phase images. Arterial-phase images are useful for detecting HCC, while the portal-phase images are also useful for assessing collateral pathways in the patients. The detectability of HCC with arterial-phase CE-3D-MRA images was proved to be equivalent to those with arterial-phase conventional MR and helical CT images. Moreover, the efficacy of evaluating collateral pathways with coronal, portal-phase CE-3D-MRA images was the best among those of digital subtraction angiography (DSA), CT/MR images, and RI portography based on our results. As a result, we believe that CE-3D-MRA may have a potential to replace DSA as an invasive technique, at least which therapeutic procedures are not required for. |
