Oncology: Total-body PET enabling critical diagnostic scans during pregnancy

Royal Free Hospital, London

PET imaging has long been restricted in pregnancy due to concerns about radiation exposure to the unborn baby, creating a diagnostic gap for expectant patients with suspected disease. At the Royal Free Hospital, total-body PET’s greater sensitivity allowed clinicians to safely reduce the radiotracer dose and, for the first time, perform an 18F-Choline PET scan in a pregnant patient. This enabled the localisation of a parathyroid adenoma that previous imaging had failed to detect, guiding successful surgery and a safe delivery.
