Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Introduction: Joint laxity has been hypothesized to be a risk factor for thumb osteoarthritis (OA). Previous studies assessing thumb biomechanics have utilized various imaging modalities including radiography, magnetic resonance imaging, computed tomography imaging, and ultrasound (US). However, these imaging techniques provide limited information on joint laxity during motion. This work...

Breast cancer is the most common cancer in women worldwide. Two million women are diagnosed annually, resulting in 685,000 deaths. Early diagnosis is critical to reducing mortality. Although mammography is the gold standard, dense breast tissues reduce detection sensitivity, potentially delaying diagnoses. Therefore, there is a need for more accessible and cost-effective supplemental screening...

4369. (G) Three-Dimensional Ultrasound for Investigating Synovial Blood Flow Changes with Exercise in Thumb Osteoarthritis

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

Introduction: Inflammation of the joint lining, or synovium, is an important aspect of osteoarthritis (OA) and contributes to disease pathogenesis and symptoms. The basal thumb joint is a common site of OA and is important for hand function. Physical therapy treatments aim to improve patient pain and function. However, the vascular changes and response to exercise are not fully understood...

4374. (G) Toward radiotherapy dose planning for cervical brachytherapy procedures using three-dimensional ultrasound images

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

Brachytherapy is a type of radiation therapy typically used in the treatment course of cervical cancer. During brachytherapy, highly radioactive sources are placed within the patient using specialized applicators or needles. While the applicators are inserted under the guidance of two-dimensional (2D) ultrasound (US), computed tomography (CT) or magnetic resonance (MR) imaging is subsequently...

4115. (G) Toward Accurate Prostate Cancer Diagnosis: Integrating PET Imaging with 3D TRUS Biopsy Techniques

Prostate cancer (PCa) is the most diagnosed cancer among Canadian men, with an estimated 24,600 new cases in 2022, making up about 21% of new cases and anticipated to cause approximately 4,600 deaths. Prostate biopsy, essential for PCa diagnosis, often uses 2D transrectal ultrasound (TRUS) for tissue extraction but suffers from a high false negative rate of 21-47% due to its inability to...
