Feasibility Study for Ultrasound-Guided Interstitial Brachytherapy for Gynecological CancersV2

Standard of care in interstitial or intracavitary brachytherapy is to insert the brachytherapy needle and applicator with no standard real-time image guidance. Interstitial brachytherapy is done under general anesthesia. Trans-abdominal and trans-rectal standard 2D ultrasound is used in some cases, but is typically not consistent and therefore its value is limited. Pre-procedure imaging in the form of MRI is used to help guide needles insertion as well as the clinical exam. Post-procedure CT is done for radiation planning
