A herniated disc is a medical condition that primarily involves the spine. It is characterized by a tear in the outer fibrous ring of a disc in between two vertebrae, causing the central gel-like portion of the spine to bulge out. This condition can be seen through various means of herniated disc imaging, such as the following:
X-ray: Even though traditional X-rays tend to be limited in producing images of a herniated disc, they are still useful in ruling out other possibilities, like tumors, fractures and infections. An X-ray is an inexpensive way of confirming the suspected presence of a herniated disc, and more advanced means of imaging may follow after confirmation.
Computed Tomography Scan: A CT scan is capable of producing a diagnostic image with a computer that reads X-rays. The images may show the size and shape of the spinal canal, as well as its contents and structures. Needless to say, a greater view of the herniated disc will be shown, if there is one.
Nuclear Magnetic Resonance Imaging: An MRI can generate three-dimensional images of the structures of our body for diagnostic purposes through the use of computer and powerful magnets. The spinal cord and nerve roots may also be seen, and images of soft tissues are better than those in CAT scans.
Myelogram: A contrast material is injected into the surrounding cerebrospinal fluid of the spine before an X-ray of the spinal canal is taken. In this herniated disc imaging technique, the structures that cause pressure on the spine are revealed, including tumors, bone spurs, and herniated discs. The need for the injection of a foreign material makes MRI a more popular option.
Electromyogram and Nerve Conduction Studies: EMG and NCS are tests that can measure electrical impulses in the muscle tissue, peripheral nerves, and the nerve roots. As a result, nerve damage as well as nerve compression can be identified.
