About this service
CT stands for Computerised Tomography and is a diagnostic technique in which the combined use of a computer and x-rays passed through the body at different angles produces cross-sectional images of tissues. Departments on both our sites incorporate modern spiral CT equipment.
Any body area can be scanned using CT although the most common examinations are:
- Head e.g. for trauma or cerebrovascular accident (stroke)
- Abdomen and pelvis
- Orthopaedic examinations
- Interventional procedures e.g. biopsies or drainages and angiograms
We provide CT scanning at Warrington Hospital and at Halton General Hospital (from the Cheshire and Mrseyside Treatment Centre).
Examinations are carried out Monday – Friday 8am – 6pm at Warrington and 9am – 5pm at Halton (Cheshire and Merseyside Treatment Centre) with occasional evening sessions.
The scanner at Warrington is also available 24 hours per day, seven days per week for emergencies.
Who's in the team?
The scanners are run by experienced CT radiographers, most of whom have undertaken additional post graduate qualifications in CT (computerised tomography).
Other Information & Downloads
Patients undergoing body scans generally need to drink a volume of contrast agent prior to their examination. This is an aniseed or orange juice flavoured radio-opaque substance that can take up to an hour to reach the entire digestive system. Often patients require an injection of an iodine-based agent as images are acquired, which highlights the blood vessels, rendering images clearer to the interpreting radiologist.
Completed examinations are then reviewed by a consultant radiologist who issues a report to the referring clinician. CT head scans, however, are typically reported by a team of three radiographers who have undertaken specialist training in this area.
