A CT scan of the brain is the most common investigation in the setting of trauma. Bleeding is detected which may require neurosurgical intervention.
Non-traumatic causes of bleeds are also best assessed by CT.
A CT scan can be done with iodinated contrast material to look for infection or tumours.
High definition scans will detect skull and facial bone fractures and sinus disease.
A CTA (CT angiogram) is a special investigation to evaluate the intracranial vessels. Typically we would be looking for aneurysms or other vascular abnormalities.
A CT scan of the chest is commonly done following an abnormal chest x-ray finding.
Intravenous contrast material is often used to better delineate the anatomy and look for abnormalities.
This is a minimally invasive procedure to detect colorectal polyps and cancers.
It is indicated for those who are unable or unwilling to undergo conventional colonoscopy.
No sedation is required.
Bowel preparation is necessary to avoid false results from faecal residue. Diet requirements together with a purgative will be explained to the patient at the time of booking. Carbon dioxide is pumped into the colon per rectum during the procedure. This is to distend the bowel somewhat. Abdominal discomfort is managed with an anti-spasmodic.
The investigation does expose you to radiation.
No intravenous contrast is used.
This procedure does not allow for biopsy or polypectomy.
Iodinated contrast material is used to opacify the vessels which can then be imaged and displayed in 3-D.
This can be done in trauma patients where vascular injury is suspected or to evaluate the extent of peripheral vascular disease (atherosclerosis).
A CT scan is a very sensitive investigation for assessing the bony structures.
3-D images can be obtained.
This investigation is commonly done in the trauma setting.
Continue with usual medication but avoid Metformin if diabetic.
