Diagnostic imaging in companion animal theriogenology.
Clinical assessment of reproductive problems in companion animals is greatly enhanced by the availability of various imaging modalities. Specifically, survey radiography, contrast radiography, real-time ultrasonography, and ultrasound-guided biopsy and/or aspiration cytology, alone or in various combinations, offer sophisticated methods of extension of the physical examination of the reproductive systems of dogs and cats. In particular, real-time ultrasonography offers invaluable assistance. It is nonionizing, largely noninvasive, rapid, and capable of providing certain dynamic information that is not conveniently available in any other way. Judging from its rapid growth in recent years, it has apparently become an integral part of the complete reproductive assessment of domestic animals. This is not to slight the importance of some of the contrast radiographic procedures that have been developed and refined. Some of them, such as maximum distention retrograde urothrocystography, provide unique information not available with presently routinely used ultrasound techniques. Other imaging modalities, such as magnetic resonance imaging, have heretofore provided limited benefit to theriogenology; that will probably change in years to come.
