ultrasonography

Because specific detection and identification of coelomic masses are usually difficult with plain radiography, other diagnostic imaging modalities (combined 2D and 3D ultrasonography and computed tomography scan) could be helpful tools to identify the presence of a tumor.

Because laying hens are the only animals that develop spontaneous ovarian cancer similar to humans, 3D ultrasonography may be a useful tool for evaluating ovarian tumors in both birds and humans.

In conclusion, 3D ultrasonography allows the sonographer to obtain better spatial perspective of the avian internal organs and is potentially superior to 2D sonography for evaluating irregularly shaped objects.
