CT Scan combines a series of scanning x-ray taken from various different angles. Then the computer will process the resulting images of bones and soft tissues in the body.
Help The Process Diagnosis
A CT scan is a circular scanner machines are great, enough to enter the adult position lay. This tool can be used to diagnose and monitor a variety of health conditions. The doctor will likely recommend a CT scan to be performed on certain occasions, such as:
- Do the diagnosis of abnormalities of muscles and bones, such as tumors or crack on the bone.
- Specify the location of the tumor, infection, or blood clots.
- Guide medical procedures when performing surgery, biopsy, or radiation therapy.
- Detect and monitor certain conditions and diseases, such as cancer, heart, nodules on the lungs, and a mass on his liver.
- Find out the injury or internal bleeding.
The use of CT scans is now also more and more used as a scan of a disease or as preventive measures. For example, CT scan of the colon for patients who have a high risk of developing cancer of the colon or the complete heart scanning in patients with high risk of heart disease.
Body parts are Scanned
During the examination with a CT scan, you will be asked to lie on a bed that can move in and out automatically. Radiology section officers or radiografer that help the examination will put your position with the right to review parts of the body can be clearly.
Some of these body parts are often examined using CT scans to find out special conditions, such as:
- Head. A CT scan is usually used in the head section to detect the network dies of a stroke, tumor, hardened network stack due to calcium, bleeding, and trauma to the bone.
- The lungs. Scanning can be used to detect any changes in acute or chronic on the inside of the lungs. CT scans that can be performed from any angle can be more accurate than x-ray scanning two-dimension.
- The heart. With the ability of rotation per second combined with pieces of a picture with high resolution and speed, a CT scan is able to provide coronary artery Imaging results are good.
- The pelvic and abdominal cavity. Scanning with CT scans is a sensitive method that can be used to diagnose diseases of the organs in the abdominal cavity. Doctors often utilize to determine the level of cancer and development. Can also be done to examine the causes of acute abdominal pain.
- Bone. CT scans are often used to scan conditions of complex fractures, especially around joints, because of its ability to reconstruct the locations from different angles. Fractures, ligament injuries, and dislocation can be found easily.
Consider The Risk Factors
During a CT scan, you will be exposed by a higher radiation level than normal x-ray scanning. This radiation is likely to slightly increase the risk of cancer. However, a CT scan has many benefits compared to the level of risk which belongs to small.
The doctor will use radiation levels as low as possible. The engine and the latest techniques can make you earn the more radiation a bit. Consult the doctor about the benefits and the risks involved before doing a CT scan.
Radiation exposure from a CT scan should preferably be shunned by pregnant women. Consider the back if you have the possibility of getting pregnant at the moment will do a CT scan.

The liquid is then issued the body through the urine.
- Although rare, a contrast fluid may cause allergic reactions in some people. Consult in advance to radiografer if you have an allergic reaction to iodine or liquid contrast before.
While the process of CT scan is being performed, you should lie down and not allowed to move. Adjust the breath like normal to get image quality obtained. A large ring that is on a CT scan machine will revolves around your body. Each time spinning will produce a new scan image. The place you lay down will move a little each time the ring is finished spinning.
Radiografer will run a CT scan machine from room next to the Chamber, separated from the examination. In the meantime, you can hear instruction and talk to the officer through the intercom.
After undergoing the process of CT scan, does not mean the results will be immediately available. The computer will process all information will then be analyzed by a doctor Radiology specialist. Report test results will then be sent to your doctor.
Radiation risk from CT scans does exist however small. The doctor will only recommend a CT scan when the conditions you really need it. Avoid a CT scan if you have possibility to contain Central. Ask for advice on the best alternative from a doctor.
