resolution - Image size of MRI T2-weighted scans -

-

i have mri t2-weighted scans of human brain. however, size of them 128x128 pixels each of 1.71875/1.71875 mm size. use these scans find perfusion parameters: cbv, cbf , mtt. however, people confused me saying quality of images not enough analysis - though images gathered medical institution.

i heard rumors since paramagnetic tracer used during scans quality sufficient, because need capture flow of tracer. if increase resolution, time between scans increase , won't capture flow of tracer correctly.

are there specialists in area explain situation of images quality? reasonably enough or should better?
