Coelomic ultrasound and computed tomography of clinically normal C. cranwelli (Anura: Ceratophryidae)

Abstract

Background

Ceratophrys cranwelli (C. cranwelli) is one of the most commonly kept pet frogs worldwide and may be presented to veterinary clinics for evaluation. However, there is limited imaging data available for ultrasound and computed tomography in this species.

Methods

Ultrasound and computed tomography were utilized to assess the organs of C. cranwelli. A total of 23 captive frogs were used in the experiment, including 3 for pre-experiment and 20 for formal experiment. The pre-experimental group received additional contrast-enhanced angiography in computed tomography. The formal experimental group was divided into 2 groups, 5 males and 5 females in each group. One group received ultrasound examination, and the other group received computed tomography.

Results

Finally, the distribution of organs within the coelom was determined, and the radiation attenuation coefficient of specific tissues and organs were measured. Additionally, describing the size, shape, and echogenicity of the liver, gallbladder, kidneys, spleen, stomach, testes, ovaries, fat bodies, and heart were described.

Conclusions and clinical relevance

This study describes the normal anatomical structure of C. cranwelli and obtains normal imaging data, which provides basic data for this species and can provide some reference for veterinarians.
