This image series is after transcatheter arterial chemoembolization (TACE). The SPIO image shows the lesions with very good CNR, although both lesions are isointense. The DWI image suggests that one lesion is still active, while in the other the embolization has been successful. The CT arterial portography image confirms this finding. The conclusion is that DWIBS also can provide information about the success of an embolization procedure.

The images at right are CT-DWI fusion images. This illustration shows that on the CT images the large lesions are easily imaged, but the dissemination can only be seen on DWIBS. This is important information for further therapy planning. The lesions are metastases of a colon cancer.

Patient preparation

The SENSE Body coil is used.

Contrast agent / injection protocol

Contrast agent is administered prior to the dynamic scan.

Other

Thanks to the exceptional contrast-to-noise ratio of DWIBS, even relatively small lesions can be seen with DWIBS, although spatial resolution is lower than in the high resolution anatomical images.
