CT (computerized tomography)

A CT scan (computerized tomography) is a medical imagery diagnostics tool that is used to create a three-dimensional image of a particular part of the body by taking a series of two-dimensional X-rays along an axis. Developed in the 20th century, this imagery tool has been used to identify and diagnose conditions as a supplement to traditional X-rays.  Some of the conditions that can be diagnosed with a CT scan include tumors, bone spurs, pulmonary embolisms, diseases, aneurysms, fractures, degenerative spine conditions, and more.

The CT scan is particularly popular because unlike traditional two-dimensional scans, the CT differentiates between different tissues and provides a level of clarity that simply can't be matched with a standard X-ray. Furthermore, the inclusion of iodine dye or another contrast material can make the CT even easier to read.

CT vs. MRI

Another popular medical imagery tool is an MRI scan (magnetic resonance imaging) because it uses magnets rather than ionizing radiation.  While CT scans are considered an excellent diagnostics tool, the use of radiation and potential adverse reactions to contrast agents are worth considering. An MRI, on the other hand, is a different kind of technology that offers a similar three-dimensional image with radio frequency, which makes it a good choice when a number of scans are necessary. 

Some other advantages of CT scans include:

• They are less expensive than an MRI
• They are more widely available than MRI
• They are significantly faster
• CT scans are generally better suited to identify problems in the chest and abdomen

A CT scan can be a great way to diagnose the presence of a degenerative spine condition, such as degenerative disc disease or spondylolisthesis.  For a free review of your MRI or CT scan and to learn about the minimally invasive treatment options offered at Laser Spine Institute, contact us today.
