Computed tomography, or a CT scan, is frequently used to make or confirm a herniated disc diagnosis. The CT scan uses special X-ray equipment and sophisticated computer software to create multiple images of the area of the spine where the suspected disc herniation is present. A CT scan is different from a typical X-ray in that internal organs, soft tissue, and blood vessels are displayed with greater clarity. This is particularly relevant for a herniated disc, which occurs when the gelatinous inner material of an intervertebral disc seeps through a tear in the disc’s outer wall.

The CT Scan Process

Anyone who has undergone an X-ray has some idea of what it’s like to undergo a CT scan. The main difference is, during a standard X-ray, a single beam of radiation is directed at the body. This small burst of radiation passes through the body and produces an image on a recording plate or film. During a CT scan, X-ray beams rotate around the body, creating a series of images that are captured by electronic X-ray detectors that also rotate. These images are then processed by a computer to create a very detailed, multi-dimensional view of various parts of the body, including the spine.

Preparing For a CT Scan

CT scans are conducted on an examination table, usually with the patient lying on his or her back, side, or stomach. Depending on whether contrast dye will be used during the scan, the patient may be asked to fast for several hours before the procedure. Metal jewelry, eyeglasses, or removable dental work should be removed. Patients should wear loose, comfortable clothing and be prepared to change into a gown if asked. Also be prepared to briefly hold your breath during the actual scanning process, because any movement can adversely affect the quality of the images.

What Does a CT Scan Feel Like?

A CT scan is entirely painless. There may be issues for people who are claustrophobic, or for small children who have problems staying still for extended periods of time. Also, people with chronic pain may experience discomfort and stress from having to remain still for several minutes. In general, the experience is fast and relatively easy.

Risks and Benefits of Using A CT Scan for a Herniated Disc Diagnosis

The risks are minimal. Pregnant women, in general, should not undergo a CT scan unless it is to determine the origin of a health problem with the fetus. Some people might experience an allergic reaction to the contrast dye, if any is used. The benefits, on the other hand, can be immense. A CT scan has the ability to display soft tissue much more clearly than a standard X-ray, which eliminates the guesswork from a herniated disc diagnosis. Knowing exactly where the disc herniation has occurred is vital information, used by a doctor to help formulate the treatment plan. In addition, if surgery becomes necessary, a CT scan can help pinpoint the precise location where the surgery should be performed.
