摘要:

Uterine clearance of technetium 99m‐albumin colloid (99mTc‐μAA) was qualitatively and quantitatively measured in 5 reproductively normal mares and 5 mares susceptible to endometritis (infertile). The percentage of 370 MBq99mTc‐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 MBq99mTc‐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 les

摘要:

Port films were acquired for all radiation therapy patients (n = 132) treated over a thirteen month period to 1] assist in initial treatment field set‐up on Day 1, 2]for quality assurance with a second port film taken on Day 7 of radiation therapy, and 3] as a means to document the radiation treatment field as a part of the patients permanent medical record. Port films were used for both patients treated with a definitive course of radiation (n = 97 patients), and those treated palliatively (n = 35 patients). The portal radiographs were valuable in terms of the initial set‐up, and to correct for any positioning or other errors at the time of the one week recheck. Changes were made, based on the initial port film on Day 1, in 53% and 57% of treatment fields for palliative and definitive radiation patients, respectively. The changes made in both definitively and palliatively irradiated patients were usually in field position, an increase in field size to include all of the tumor, or a decrease in field size to spare normal tissue. Fewer changes were necessary based on the Day 7 recheck port films, but these day‐7 rechecks are recommended for quality control. Based on the high frequency of changes introduced because of the initial port film findings, it is recommended that port films be incorporated on a routine basis in veterinary radiation th
