Uterine clearance of technetium 99m-albumin colloid (99m Tc-μAA) was qualitatively and quantitatively measured in 5 reproductively normal mares and 5 mares susceptible to endometritis (infertile). The percentage of 370 MBq 99m Tc-μAA cleared from the uterine lumen within 2 hr of intrauterine infusion was measured in 10 mares on day 3 of estrus and 48 hr after ovulation. The procedure was repeated 3 times on day 3 of estrus in 6 mares to determine repeatability. Six mares were infused with 1110 MBq 99m Tc-μAA on day 3 of estrus to evaluate the effect of increasing the dose to reduce the imaging time. There was no statistically significant difference in the mean percentage of radiocolloid cleared from the uterus during day 3 of estrus or 48 hr after ovulation or in the percent cleared when the studies were repeated in individual mares. There was no statistically significant difference in uterine clearance between the 370 and 1110 MBq dose studies in each mare from 15 to 120 min. Reproductively normal mares cleared approximately 50% of the radiocolloid from the uterus by 120 min while susceptible mares cleared less than 15%. 相似文献
