Ultrasonographic study of uterus and fallopian tubes in domestic short-haired cats after administration of Levovist® contrast agent

Abstract

This study investigated the effects of the Levovist^® contrast agent on ultrasonography in domestic short-haired (DSH) cats, focusing on the uterus and fallopian tubes. The main question was whether Levovist^® could enhance visualization of these small structures. Twelve female DSH cats underwent a complete blood count (CBC) before and after receiving 5 microliters of Levovist^® via a Foley catheter. Ultrasound examinations were performed using a linear probe, and statistical analysis was conducted using ANOVA (p<0.05). Results showed that prior to Levovist injection, differentiation between the endometrium and myometrium was not possible. Post-injection, the average thickness was 0.95 ± 0.1 mm for the endometrium and 0.81 ± 0.12 mm for the myometrium, indicating significant improvement in imaging. However, effective evaluation of the fallopian tubes was not achieved. In conclusion, Levovist significantly enhanced ultrasound visualization of uterine structures in DSH cats, highlighting its potential in veterinary reproductive diagnostics and improving imaging techniques for small anatomical structures.
