| When to shim? |
On what sequences should a shim volume be added? (GE scanner)

| GE 8 channel Body Coil Artifact |
Have a GE 1.5T HDxt. Problem: experiencing symmetric artifacts in abdominal images. Artifact seen in most anterior images: Some are rectangular in appearance, another reminds me of a plastic knife. All patients are changed in gowns/pants prior to entry into MRI suite. The body coil in question has been changed 3 times but the artifact remains. I suspect this is a hardware reconstruction issue, however, the engineer thinks it is operator error. I have run this sequence with and without options. This is an SSFSE, breath hold sequence. Has anyone encountered this issue?

| Second contrast dosage on COW MRA |
Did anyone know how much Gadovist should I inject after first time COW MRA is failed on 1.5T Philips TOF sequence.
First time dosage is 0.15ml/kg
(Patient with normal kidney function eGFR>60)

Try running a B1 Map followed by Calibration. Set RF Drive mode to Optimized. This is supposed to optimize for your Patient. Supposed to reduce dielectric effect/shading for Lumbar and Abdomen.
You can find under GE Additional Abdomen Sequences.
Or you can run Ideal with Dixon technique. Turn on IN phase will give you T1 FS & IN Phase is you plane T1. I believe this takes care of the artifact.

| Contrast on an 3T |
Studies (for example http://pubs.rsna.org/doi/full/10.1148/radiol.2373041672 , http://pubs.rsna.org/doi/full/10.1148/rg.287075154 ) suggest that contrast enhancement of gadolinium is increased at higher field strengths. That can be used to lower the dose or receive higher contrast effects. It also depends on the contrast sensitivity of the used sequences and the examined body part.
