Patients usually lie in the tool scans and x-ray machines (x-ray) and then perform scanning (scanning) on the patient's body.
CT scans can produce a detailed picture of the soft tissues, muscles, internal organs, bones, and most importantly, tumors or other irregularities.
While the method is very widely used as diagnostic imaging, CT scan also has some drawbacks that must be considered.
Excess CT Scan
1. very detailed
Of all internal imaging procedures available, CT scan is the most detailed so as to provide the most complete picture of what is happening inside the patient's body. CT scans are very useful and widely used to diagnose cancer.
2. Painless
Procedure is non-invasive CT scan and painless. CT scan procedure can be done relatively fast and comfortable for most patients.
3. clear information
CT scans give doctors a very clear information regarding the location and spread of the tumor that is very helpful in planning biopsy, surgery, radiation, or other treatments.
Disadvantages CT Scan
1. radiation
Compared with other diagnostic tests, CT scans provide a higher radiation dose to the patient.
Scans were performed only once generally will not cause a problem. But that procedure is repeated to increase the risk of cancer due to radiation exposure is repeated.
2. allergic reactions
Patients who had a CT scan may receive a dose of a substance known as "contrast agent," which contains iodine.
Contrast agent is needed in order to scan the particular body part has better resolution so it is more easily analyzed.
Some patients may experience an allergic reaction to the contrast agent with the symptoms include a metallic taste in the mouth, hives, and shortness of breath.
The good news, contrast agents containing iodine is not readily available and more widely used.
3. misinterpretation
Because CT scans are very detailed, it could potentially make a mistake doctors diagnose minor abnormalities in the body as a serious problem like cancer, for example.
This will certainly cause anxiety in patients and additional costs to conduct follow-up tests or treatments that are not necessary.
