The dynamic contrast sensitivity, improved cerebral perfusion MRI?

Hi there many situations in which we can use MRI to assess cerebral blood flow. I want to compare groups or effect of medicaiton. But how Can I do this using the best DSCE-RM? For example Rempp al. al. fits both the arterial input function (bolus) and the tissue curve (bolus) with a gamma variate. After Fourier-deconvolution is used the "true" in the curve of the tissue concentration. But for me, none of this works. For example I have an Echo planar imaging scan at a resolution Temperal 1.5 seconds. If only blood manually locate the curve of the surface of the circle of Willis -- and then the second curve in the (periventricular) white matter Nice curves I - and certainly not great deconvolution. The curves of the tissues are so low that curves artery. And the bowl of the curve of the artery is larger than the bolus tissue. I do not know what to do. Is this a problem of image acquisition is Should I use the filter? HELP!

There are several ways to examine brain function and blood circulation. fMRI (functional) MRI show how the brain works. Also, and MRA / MRV magnetic resonance angiography: Angio MRI Venography. It's something you need to connect to a radiologist special Neuro. They know more. Based on my experience in hospital (5 years) MRV w / without contrast (gadolinium) is probably the best method to study blood flow in the brain.
