Sentence examples for determining contrast from inspiring English sources

But the lack of standards for determining contrast ratios leads to wild claims.

If the delivery of the contrast medium to a tissue is insufficient (flow-limited situations or where vascular permeability is greater than inflow) then blood perfusion will be the dominant factor determining contrast agent kinetics; this situation is commonly found in tumours.

If the delivery of the contrast agent to a tissue is insufficient (flow-limited situations or where vascular permeability is greater than inflow), then blood perfusion will be the dominant factor determining contrast agent kinetics and Ktrans approximates to tissue perfusion per unit volume (Taylor et al, 1999; Tofts et al, 1999).
