Contrast-enhanced CBCT With C-arm HyperSight Technology (IV-CBCT)
9. juni 2026 opdateret af: University Health Network, Toronto
Contrast-enhanced CBCT With C-arm HyperSight Technology: A Feasibility Study
This is a single-arm prospective, feasibility study evaluating the intravenous contrast-enhanced cone beam computed tomography (IV CBCT) for image guidance during radiotherapy.
Patients treated with SFRT will receive IV-contrast enhanced CT and fMRI before treatment for simulation purposes.
Additionally, patients will receive mpMRI just before and IV-contrast enhanced CBCT during their second and last fraction of RT, in addition to the standard of care CBCT that is acquired for daily image-guided patient positioning.
Patients will undergo both IV-contrast enhanced CBCT and treatment on the TrueBeam with HyperSight imaging capability.
We hypothesize IV contrast enhanced CBCT is feasible, well-tolerated by patients and improves the visibility of the target.

Two half-arc IV-contrast enhanced CBCT scans and mpMRI seuqences in addition to their routine standard of care CBCT that is done as part of image-guided radiotherapy.
These scans will be done during the second and last fraction of treatment.

Feasibility of IV-contrast enhanced CBCT during image-guided radiotherapy
Tidsramme: 18 Months
|
Feasibility of IV-contrast enhanced CBCT in visualizing tumors, vascular structures and tumour micro-environment changes during image-guided radiotherapy.
The contrast-to-noise ratio, measuring the ability of an imaging modality to differentiate between various contrasts against the background noise, will be calculated and compared between CT and CBCT, and between with and without contrast acquisition.

Patient preferences and comfort with the use of IV CBCT during treatment
Tidsramme: 18 Months
|
All patients will be asked to complete a patient experience survey to gauge their perceptions of receiving additional IV contrast during their CBCT.
All questions are answered on a 5-part Likert scale (strongly agree to strongly disagree) and grouped according to construct (knowledge, feelings and benefits).
Data will be analyzed using descriptive statistics.
Correlations will be examined between patient demographics (age, gender, ECOG performance status, ) and survey responses to identify any trends or specific needs.
