Assessment of microheterogeneity of blood flow in the rat urinary bladder by high‐resolution digital radiography

Abstract

radiography combined with the deposition of 3 H-labelled desmethylimipramine. The spatial pattern of blood flow was quantified by the coefficient of variation of the regional flow (CV = SD /mean). RESULTSMuscle blood flow was less than mucous blood flow (muscle : mucosa, 2.9 : 5) in the empty bladder. In the muscle layer the blood flow distribution was more heterogeneous than that in the mucosa, with a mean ( SD ) CV in muscle and mucosa of 0.33 (0.033) and 0.16 (0.019), respectively ( P < 0.001) at the capillary level.
