The Usefulness of CT Scans

As with conventional X-rays, there are so many the usefulness of CT Scans can be used on almost any part of the body and organs, from the brain, bone, gastrointestinal tract to the blood vessels. Some examples of the use of CT Scans:

• Head: hemorrhage, stroke, hematoma, brain tumor
• Bone: a complicated fracture, disc herniation, tumor
• Pulmonary: lung cancer, pneumonia
• Liver: hepatitis, liver cysts, liver cancer, liver cirrhosis
• Lymph nodes: detection of metastases, changes in the immune response
• Stomach: intestinal abscess in Crohn's disease, tumors of the colon and rectum,
esophagus tumor spread
• Blood vessels: acute bleeding by accident or aneurysm

CT scans can also help removal of tumor tissue or tumor samples (CT Assisted Biopsy). Comparison of CT Scans over time can provide information on the response to treatment, recovery after surgery or if recurrence.

The use of CT Scans is the most advanced technique called virtual endoscopy (virtual endoscopy) in which the doctor can see the surface of internal organs such as the lungs or intestines without having to insert the endoscope into the body.

Side Effects

Computed tomography uses X-ray radiation intensity tens to hundreds of times more powerful than regular x-rays. It is known that exposure to radiation increases the risk of cancer. But so far the radiation CT is considered still within safe limits.

The use of contrast agents do not give a harmful effect on most people. In a minority of people who have an intolerance or allergy to contrast agent material, symptoms such as nausea or rash may occur. But in general, these symptoms will soon disappear with or without treatment.
