 Radiography: follicles appear as non‐calcified, round to ovoid, variably sized soft‐tissue opacities in the mid to caudal coelom. At times, the follicles may either be large enough, or in large enough numbers, to encompass over 50% of the coelomic cavity.

 Ultrasound: early follicles appear as anechoic and progress to have more echogenicity as they mature or fail to ovulate. Follicles with a more heterogeneous distribution within the lumen should be highly suspicious of being retained follicles as the material within becomes firmer and inspissated. Ultrasound examination and aspiration of any free fluid can also be used to rule out egg yolk coelomitis.

 CT scan and MRI: both these modalities are extremely sensitive at identifying follicles and can better assess the differences in size, shape and content of the follicles.

 Coelioscopy: coelioscopic examination allows for confirmation of the presence of follicles and evaluation of their color and size to help make a determination of whether the presentation may be pathologic.
