CT

A CT scan gives more detail than the standard X-rays. In a CT scan, multiple X-ray beams circle all around the body to view bones and organs from many different angles. It is usually in the form of a short tunnel, where a person will be set inside. These images can be used to check for tumor sizes, internal bleeding, infections, and bone fractures. To make images clearer, a contrasting substance may be taken (Frysh). A CT scan is a very effective way to find tumors in patients. The scans can detect tumors 1.5-2.0 cm in diameter. This technology has 95% accuracy when looking at intra-abdominal abnormalities, making treatment decisions easier. CT scans can be used to investigate and identify strokes in a patient's head. These scans are able to diagnose a stroke, identify the type of stroke, and eventually manage the disease. CT scans are also used to investigate dementia. The risk of cancer due to increased use of CT scans is increasing. This risk is especially relevant for children due to sensitivity of radiation-induced cancer compared to adults. Risks of leukemia and brain tumors have been revealed after exposure from computed tomography scans (Hussain et al.).
