What should you know about PET scan uterus?

The PET component shows how the administered FDG tracer is distributed, while CT identifies the uterus, cervix, lymph nodes, and surrounding structures. Depending on the reason for referral, the images may help evaluate a known gynaecological cancer, look for disease beyond the original area, or compare findings after treatment.

Uterine activity can vary with normal hormonal and reproductive changes. Inflammation, infection, recent procedures, and other non-cancer causes can also alter the appearance. Tell the imaging team about your menstrual history, pregnancy or possible pregnancy, recent biopsy or surgery, and any pelvic symptoms so the report has useful context.

Follow the centre's instructions about food, water, activity, and medicines. Bring details of previous scans and procedures if requested. Wear clothes that allow easy access and remove metal objects before imaging. You will usually rest after the tracer injection and then lie still while the scanner records images from the required body regions.

During the visit, immediately report breathing difficulty, throat or facial swelling, faintness, or intense pain at the injection site. Seek urgent care for breathing problems, collapse, or a rapidly spreading rash after leaving. Contact your gynaecology or oncology team promptly for heavy bleeding, severe pelvic pain, fever, or new concerning symptoms, whether or not a scan is scheduled.

Ask why the uterus and nearby areas are being scanned, whether menstrual timing matters, whether tissue sampling is planned, and how the report will affect your next appointment.
