[Effects of Lung Ventilation Perfusion Imaging Examination on Pregnant Outcomes of Rabbits.]

OBJECTIVES: To examine the pregnancy outcomes of rabbits being subjected to pulmonary ventilation perfusion imaging examinations.

METHODS: Pregnant rabbits were randomly divided into two groups: control group and experimental (lung ventilation-perfusion scintigraphy) group.The pregnancy outcomes were measured using indicators of miscarriage,premature birth,and stillbirth,as well as malformations and developmental abnormalities of offspring over a three-month period.

RESULTS: No significant differences in miscarriage,premature birth,and stillbirth were found between the two groups.No obvious deformity appearances in the offspring were observed.The two groups showed no statistically significant differences in fetal progeny-intrauterine growth and developmental indicators measured by body mass,head circumference,abdominal circumference and length.

CONCLUSIONS: Lung ventilation-perfusion scintigraphy examination has no effects on pregnant outcomes measured by miscarriage,premature birth,stillbirth,fetal teratogenicity and fetal growth.
