| CE MRA of the Liver |
The above statements are correct, also remember that the portal vein is brightest in the first pass of contrast through it so having a short sequence for the arterial phase <20 seconds and going straight into the portal phase is important(ie one inspiration/expiration only between repeating the sequence). The portal vein will become brightest within 30 seconds of the artery.

Like lily lily we use a muliphase MRA with 3 phases (artery, portal vein and late phase).
We use an amount of 30 ml Gadolinium with an injection rate of 5 ml/sec. With this high flow rate, you get a more concentrated bolus and therefore a higher contrast for the second phase. We use CENTRA k-space acquisition and reduce the scan time with SENSE (a parallel imaging technique like ASSET ), this will help for a better timing.

Which injection rate and amount of Gadolinium works best for CE MRA of the liver with a good portal venous contrast? We have a power injector and a 1.5 T system. With a flow rate of 3 ml/sec and 20 ml contrast agent the arterial contrast but the portal phase could be better. Our MRA's are done with 15 sec. scan time for one breath hold.

Hi Oscar,
depending of the indication (tumor, stroke, haemorrhage, epilepsy, inflammation, malformation....) different sequences are useful for brain MRI.
A protocol for a wide range of indications: sagittal T2, coronal Flair, transversal DWI and transversal T1 without and with contrast medium. In case of a result a second plane of a T1 sequence after contrast e.g. coronal is recommended.

We use Endorem for liver imaging. We will change to Resovist. Does anyone have experience with this new contrast agent? By now, we use post contrast a T2 weighted sequence with an echo time of 60 (1.5 T Intera). Do we have to pay attention to something, what’s different to Endorem?
