Scanning and Tests

MriDifferent types of imaging machines are used to perform different types of brain scans. The most common types of scan in the UK for both diagnosis and follow-up are Computerized Axial Tomography (CT or CAT) and Magnetic Resonance Imaging ( MRI).

Positron Emission Tomography (PET) is available at only a few UK Neuro-oncology treatment centres because of the specialist nuclear medicine equipment and expertise required, and so it tends to be used more for research than for routine diagnosis.

All scans are painless and you will not be able to feel any beams or rays going through you rbody.

As well as being used to help diagnose and review patients, additional scans would be scheduled both before and after any treatment received; beforehand to plan treatments and after to assess levels of success. Scans after treatment are unlikely to be immediate, as sometimes it is difficult to tell from a scan what is scarring from Radiotherapy or surgery and what is tumour, for example; so if the brain can be left to recover for two to three months before being reassessed, a more accurate indication of status can usually be gleaned. However scans taken during and immediately after surgery (before the anaesthesia has worn off) can be very helpful to indicate the amount of tumour which has been resected (taken away).
