New scan cuts radiation for prostate cancer patients
NCT ID NCT07357259
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new way to do PET scans for men with high-risk prostate cancer. Instead of two full CT scans, it uses one CT plus a delayed PET-only image, which may lower radiation exposure. Researchers will check if the delayed images match the standard ones well enough. The goal is to make the scan safer and faster without losing diagnostic quality.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Gallium-68 PSMA radiotracer
- What this could lead to
- If successful, this could lead to a safer, faster imaging protocol that reduces radiation exposure for men with high-risk prostate cancer.
- What could go wrong
- This is an early-stage imaging study, not a treatment trial. The delayed scan may not match standard images well enough, or the benefit may be small.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Newly diagnosed prostate cancer undergoing staging, or * Biochemical recurrence following prior radical-intent therapy (surgery and/or radiotherapy), or * High-risk prostate cancer, defined as Gleason Score ≥ 8 or PSA ≥ 20 ng/mL. * Written informed consent and authorization for personal data processing. Exclusion Criteria: * Genitourinary comorbidities that could interfere with imaging or interpretation. * Intermediate- or low-risk prostate cancer. * Delayed acquisition performed on a PET/CT scanner different from the standard acquisition. * Additional PET/CT required due to artifacts compromising diagnostic quality (e.g., urinary retention, excessive motion). * Patients previously enrolled who require repeat PET/CT as a new visit. * Inability to provide informed consent or impaired decision-making capacity. * Known hypersensitivity to the radiopharmaceutical or its components. * Contraindications to PET/CT (e.g., severe claustrophobia, morbid obesity, inability to cooperate).
