Scan Info
What is a CT scan
CT stands
for computed tomography(sometimes called a CAT scan), it uses
X-rays to build up a cross sectional image of the body. There is a
picture of a CT scanner above. The main working parts are the table
(where the patient lies) and the gantry which is 'ring' shaped and
contains a rotating x-ray source and detectors. Data taken from the
body is built up by a computer system into a diagnostic image which
can be interpreted by radiologists.
Who needs a CT scan
CT is an excellent way of looking at the internal anatomy of the
body. It is the imaging investigation of choice for a range
of symptoms relating to many body areas including the chest ,
abdomen, pelvis, bones head and neck. Doctors will use it to
investigate a whole variety of symptoms from breathlessness, cough,
chest pain to abdominal pain, weight loss and many others. It is an
investigation which can be used to obtain further information about
established or suspected diseases eg. Cancers.
