CT Scan Radiation

Computed tomography — also known as computerized tomography, or just CT — is an important imaging tool that allows medical professionals to provide patients with the best possible care. CT scans generate a detailed look at the internal structures of the body without the need for an invasive procedure. Patients sometimes worry about CT scan radiation, however. Computed tomography does expose the patient to ionizing radiation, but not having the procedure may be a riskier than the exposure to radiation.

CT Scan radiation

A CT scan uses x-rays to create an image; x-rays are a form of ionizing radiation. Radiation exposure during computed tomography is higher than the radiation exposure during a standard x-ray procedure.

The National Cancer Institute states that a regular-dose CT scan of the chest exposes the patient to a 7 millisieverts (mSv) dose of ionizing radiation. The average American receives roughly 3 mSv each year from naturally occurring ionizing radiation.

Although computed tomography does expose the patient to radiation, it has several potentially life-saving applications. It’s used to diagnose circulatory diseases, detect blood clots, assess head, neck, and spinal injuries, and to detect cancers. There are circumstances in which not receiving a CT scan is a bigger risk than the patient’s exposure to radiation.

Low radiation CT

Low radiation computed tomography provides the highest quality images while reducing exposure to ionizing radiation.

A low-dose CT scanner reduces radiation exposure by 50% to 200% depending on the type of examination. For example, a low-dose CT scan of the chest exposes the patient to 1.5 mSv compared to the 7 mSv from a regular-dose scan.

In addition to limiting radiation exposure, these exams are often more comfortable for the patient and the there’s no reduction in the quality of the image. MANA offers low radiation CT scans in Northwest Arkansas. Your physician can schedule an appointment by calling 479-582-7383.
