Siemens Skyra 3 T
In MR cardio exams I perform a sequence called trufi-frequencyScout-multi.

This sequence provides several images (from a same slice) each one with a specific frequency.
After this, we choose the better image and use its frequency value as an entry in the cine subsequent sequences.

The question is: Where do I find the place to insert this Value in the Cine sequence?
I travelled all the cine sequence away and could not find.
Anyone can help?

Thanks a lot.

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

Muscle shading in 3T Images
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.
