| CE MRA of the Liver |
Dear bob mitchell:
The injction rate and amount of C.M. of liver MRA on our experience, that are the same yours. And that can got the very will artery phase around 15sec(using smart prep. to track or fluoro-trigger to mointor and catch the C.M. arrival time ) after injection C.M. Another item about the portal vein you can settle multi-phase on option menu. After artery phase then take rest to breath and BH again(about 3-5sec) then do the second phase(portal vein phase).
you can try the way.
ps: you can try to performance it combinate ASSET, it will reduction the scan time and improve the tempory resoultion.

| CE MRA of the Liver |
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.

| Temperature Monitoring |
The ideal solution for temperature monitoring during MRI is by using a fibre optic temperature monitoring system.
Fibre optic has inherent distinctive advantages as they are intrinsically safe, 100% immunity to EMI and RFI hence, the temperature reading is reliable.
They are a few manufacturers for this type of system with varying price range but one thing to note is to find out if the system is suitable for human physiological use. Most systems have not gained FDA or other regulations approvals for clinical use.
System and sensor accuracy, repeatability and packaging are also important factors to keep note of.

| Brain Protocol |
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.

| Power Injector |
we have had great success with a Medrad Spectris power injector - peripheral angios can be done using 20mls gad at flow rate of 1ml/sec without venous return.(siemens symphony magnetom 1.5T)
