MR arteriography using an implantable port system: a new method in assessing perfusion abnormalities during hepatic arterial infusion chemotherapy.
We present a case in which MR arteriography (MRA) with an indwelling catheter was used in a perfusion study of intrahepatic arterial chemotherapy for liver metastases. After embolization of collateral vessels using platinum coils, CT imaging was disturbed by strong artifact. However, platinum coils produced no MR artifact. In addition, MRA had greater advantages in depicting perfusion defects than perfusion scintigraphy. We consider MRA useful in assessing perfusion abnormalities during intrahepatic arterial chemotherapy.
