To ask the Secretary of State for Health how many full positron emission tomograph scanners are available in the NHS; and where they are located. 
There are five positron emission tomography (PET) scanners in National Health Service hospitals in England used for routine clinical assessments. They are situated at Guys, St. Thomas', Middlesex, Mount Vernon and Hammersmith Hospitals. Four other PET scanners are used primarily for research and are located in dedicated research facilities in London, Cambridge and Manchester. In addition, three private facilities, including a new mobile PET scanner in London, are available for NHS patients.
To ask the Secretary of State for Health what the average waiting time is for PET scans. 
Data is not collected centrally on waiting times for positron emission tomography (PET) scans. The length of time that a patient may have to wait for any scan is dependent on their clinical condition. Emergency cases need to be seen immediately. Other cases will be carried out as quickly as possible, dependent on the clinical priority of all patients waiting to be scanned.Where a scan forms part of the diagnostic process for a patient urgently referred with suspected cancer, this will be covered by the target of a maximum two months wait from urgent referral to first treatment, which will be in place for all cancers by the end of 2005.
