Background Information: Transvaginal ultrasound (TVUS) is a valuable, yet often underutilized modality for performing gynecologic interventions. Traditionally, radiologists have used transabdominal CT or ultrasound approaches. TVUS-guided procedures can aid in the management of pelvic lesions that are not amenable to other image-guided interventions. The purpose of this exhibit is to provide a comprehensive, case-based review and comparison of transabdominal (CT and ultrasound) and TVUS-guided interventions to increase familiarity with multiple modalities for treating gynecologic lesions.

Educational Goals/Teaching Points: Educational goals of this exhibit are to review indications for TVUS-guided and transabdominal procedures, including patient selection; to provide selected case examples with correlative pathology; to discuss tips and pearls for performing both TVUS and transabdominal procedures; and to consider the advantages and limitations of each modality compared to others.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques: This exhibit will discuss the use of transvaginal and transabdominal procedures in the management of gynecologic conditions. This will include a literature review. Illustrative case examples for each modality will be discussed, including but not limited to tissue sampling, catheter drainage, and aspiration. Pathologic correlation will also be provided. Postprocedural management and benefits/limitations of each modality will also be addressed.

Conclusion: By utilizing transvaginal ultrasound in addition to more conventional methods, radiologists can expand their scope of practice to provide an additional management alternative for gynecologic conditions. Radiologists who are comfortable employing multiple modalities for procedural guidance can play an important role in patient care and help clinicians achieve better clinical outcomes.
