A CT Whole Body without contrast is typically ordered to help diagnose and evaluate various medical conditions, such as cancer, infections, or injuries. It can provide detailed images of various organs and structures, which can help doctors determine the cause of symptoms or abnormal test results.
When this test is required
A CT Whole Body without contrast may be requested by a doctor if a patient experiences symptoms related to various medical conditions or if they are undergoing follow-up testing for a known condition. It may also be ordered as a screening test for certain populations, such as individuals at high risk for cancer.
What the Test Detects
A CT Whole Body without contrast uses X-rays to create detailed images of various body parts, including the head, neck, chest, abdomen, and pelvis. The images can help doctors identify and evaluate medical conditions affecting these areas.
Preparation for the Test
Before the test, a patient may be asked to change into a hospital gown and remove any metal objects from their body, such as jewelry or belts. Depending on the facility, the patient may be required to fast for a certain period before the test. In some cases, a contrast dye may be administered orally or rectally to improve the visibility of certain structures.
Sample Requirements
No samples are required for this test. It is a non-invasive imaging procedure that uses X-rays to create images of the body.
Additional Notes
A CT Whole Body without contrast is a safe and painless procedure that takes only a few minutes to complete. However, it involves exposure to ionizing radiation, so it should only be performed when necessary. Patients with kidney problems or allergies to contrast dye should inform their doctor before the test. Pregnant women should avoid this test, as radiation exposure can harm the developing fetus.
