Partial volume effects on vascular T2 measurements

Quantitative, vascular T-2 measurements are of interest for applications such as MR oximetry, In the situation of a vessel with long T-2 relaxation times embedded in tissue with relatively short T-2 values, contamination of the blood signal from the surrounding tissue can bias T-2 measurements. Limited data sampling and vessels running obliquely through the imaging slice can cause significant signal contamination, Using a model of these effects to predict the behavior of T-2 measurements under a range of conditions, a set of parameters that provides the best combination of measurement accuracy with a signal-to-noise ratio as high as possible is proposed.
