Hi we have been using the standard siemens sequences for COW, and find them ok, as with the venogram sequences. What do you not like about the standard- theyre long, but 'id like to know why you don'tlike them, maybe we're missing somthing..

Some experiments with superparamagnetic contrast agents such as Feridex/Endorem with labeled cells showed a black appearance on T2 weighted sequences, which was easy to see. The less dominant T1 effect, bright on T1 weighted images was more subtle. (I found this also interesting http://www.nature.com/nm/journal/v7/n11/full/nm1101-1241.html and the article 'MR and iron magnetic nanoparticles. Imaging opportunities in preclinical and translational research' on http://www.tumorionline.it/cerca.php )

Does changing the gradient mode from "fast" to "whisper" have an effect on the image quality? I just did a PD FS on a knee and compared two sequences that were exactly the same except for one was "fast" and the other was "whisper", which also changed the TR and TE very slightly (TR from 1970 - 2100 and TE from 29 - 31). The whisper sequence was noticeably lower quality and I can't figure out why.

Okay... So below is what the MRI breakdown tells me, can someone tell me if I should definitely be worried... I think it says I have brain lessions associated to sinus problems, but then they said it might be a sign of MS? HELP... Any additional clarity will be greatly appreciated...
Technique: Sequences spin - echo-enhanced in T1, T2 protons and density, flair at the axial, sagittal and coronal, 5 mm thick.
Report:
Small punctate signals focal hypo-intense in T1 and hypertensive in the other sequences and without apparent mass effect in the lobar white matter and subcortical frontal, bilateral parietal subcortical and peri-ventricular the atriums of both lateral ventricles.
Others are not displayed disturbances of encephalic parenchyma or blood collections or intra extraxiales. The medulla oblongata, pons and the cerebral peduncles with normal morphology and signal. Tanks of the base, the subarachnoid space and the cortical ventricular system above and infratentorial not dilated, without compression or movement.
Thickening of the lining which is the frontal sinuses, ceidillas etmoidales and maxillary sinuses, in the latter left with the presence of liquid level.
Comments
Many small pictures that compromise the lobar white matter and subcortical frontoparietal and peri-ventricular atrial bilateral and that although might be nonspecific, it is not possible to rule out entirely demyelinating etiology, so it must be correlated with the clinic's patient, findings of physical examination and clinical-. A new study of control in timely fashion or according to clinical course can be useful.
Pan-chronic sinusitis with signs of acute in the left maxillary sinus.
