What this research studies

You will have 3D ultrasound scans of the vaginal wall before and after intravaginal brachytherapy to look for radiation-related changes. The scans combine B-mode imaging, ultrasensitive microvessel imaging (UMI), shear-wave elastography (SWE), and quantitative ultrasound (QUS) to measure blood flow, stiffness, and tissue microstructure. The team will develop the imaging system and then test it in about fifteen endometrial cancer patients receiving IVRT to see whether ultrasound metrics link to standard clinical exams and symptoms. Imaging visits will be timed around your treatment so changes over time can be tracked.

Who could benefit from this research

Good fit: Women with endometrial cancer who are scheduled for postoperative intravaginal brachytherapy (IVRT) are the ideal candidates.

Not a fit: Women who are not receiving pelvic radiotherapy or whose vaginal symptoms are due to non-radiation causes may not benefit from this imaging approach.

Why it matters

Potential benefit: If successful, this could provide objective imaging measures of vaginal scarring and stiffness to detect problems earlier and help guide treatments that reduce pain and sexual dysfunction.

How similar studies have performed: Ultrasound elastography and microvessel imaging have shown promise in other tissues, but applying this exact multiparametric 3D approach to radiation-induced vaginal toxicity is largely novel and untested in large clinical trials.
