| interleaved slices and mean intensity difference in adjacent slices |
With interleaved slice acquisition for example in each TR first the odd slices, and then the even slices are acquired. Differences in signal intensity may occur by changes between these acquisitions (like movement), especially with a long TR. In particular, for fMRI sequences with interleaved slice acquisition a slice time correction is recommended to get accurate measurements.
However, I think "large" signal intensity differences with interleaved slices (except fMRI) are rarely seen with usual sequences and sufficient processing (interpolation) algorithms.

Can anyone give their opinion on this MRI wether the pec tendon is partially ruptured, fully ruptured, or intact?

Hello!
Is my first time in this forum! I read it a lot this forum, is very helpfull for my job!
I have a dificult in my mri machine.
First i would like to now how can i construct a bolus teste manualy! I don't have smart prep. What sequence i must use and what parameters i must choose.
Second, can you expline to me the diference between centric fill of K-space and non centric?
When is the best time to star the sequence after take the time injection.
My regards
Marco Costa

The BEST study guide is Medical Imaging Consultants: MRI Registry Review Program. They guarantee you will pass or your money back. I studied for 6 months and passed.

I do not doubt that there are small and may be in special cases (perfusion, MRA, etc.) useful differences.
However, I have a lot of practice in MRI and in my opinion, you are right, the differences are small and you can run every type of MRI scans with all conventional Gadolinium containing contrast agents.
