Radiotherapy Planning PET/CT
≈ 25 min including positioning
In simple words
For radiotherapy, a millimetre matters. This scan is done in the exact position you will be treated in — flat table top, same immobilisation devices, laser alignment marks — so the metabolic map from PET can be fused directly into the radiation planning software. The result is a beam shaped around live tumour and steered away from healthy lung, spinal cord or salivary glands.
Questions this scan answers
- Exactly which tissue should the radiation beam treat?
- Which nearby healthy organs must be spared?
The Prismaa difference
Sharper images mean tighter, more confident target volumes. Less guesswork in the margin is less dose to healthy tissue and fewer side effects.
Usually recommended for
- Patients planned for radical radiotherapy, IMRT, SBRT or re-irradiation
- Head-and-neck, lung, oesophagus, cervix and prostate protocols
How to prepare
- Same fasting rules as a standard FDG scan.
- Wear the immobilisation devices your radiotherapy centre has provided, and bring your planning instructions.
