GE signa excite 3T - clustered volume acquisition
I am wondering if anyone has experience with so called 'clustered volume acquisition' on a GE signa excite 3T. Clustered volume acquisition (or sparse acquisition) means that you acquire images within the first 1000 ms of a 2000 ms TR, for example (Edmister et al., 1999, Human Brain Mapping). This method is useful because the machine will stop producing scanning noise in the final 1000 ms of the TR, which can then be used for recording speech inside the scanner (in fmri applications).
I am asking whether 1) this sequence can be programmed from the parameters menu on the scanner console, or 2) whether it requires compilation of a new pulse sequence.

GE SWAN sequence parameters. Does anyone know how to make this faster, but not effect image quality?

Dears!!
I try to understand why TIRM have a long TR and long TE ( value of T2 image ) but sequences bring a T1 mark

Thanks!!!

MRI of knee ? bone fragment (pic attached)
Hi all,

Just wondering if anyone can help me with the provisional diagnosis of my MRI of my R knee. The technician said appears to be a fracture. Was walking down stairs at work and landed hard on R leg. Pain since.

Can anyone confirm this with attached MRI image. It appears to me a fragment is there but i could be very wrong.

I got ortho review in 5 days.

Any help is much appreciated

Merging stacks
Hi,

Hopefully someone can offer me some help!

I have three stacks of 35 images covering the proximal to distal thigh, and I'm wondering whether there is a way of merging these three stacks together into one stack?

These images are from the transverse plain, and all have the same metadata.

Thanks in advance,

Llion
