However, when the herniated disc becomes bulged or protruded, it can begin to cause severe pains. On its own, an herniated disc might not produce any symptoms in the patient, therefore there are many individuals who live with undiagnosed back conditions. 1 MRI for herniated disc with or without contrastĪs a general rule of thumb, MRI scan results are interpreted by the physiological symptoms exhibited and experienced by the patient. This hernia will often show up as a contrasting spot in an MRI scan.įig. When the outer layer of the disc is ruptured, called an annular tear, its inner nucleus jelly squeezes out into the spinal canal and forms a hernia. In most cases, these discs are subjected to constant motion causing wear and tear. To accurately read a lumbar MRI scan for a herniated disc, patients must possess a basic understanding of the anatomical structure of the lumbar spine.There are 5 vertebrae components in the lower back and they are separated by two types of joints including facet and discs.

MRI scans are particularly sensitive for detecting disc injuries such as a lumbar disc herniation, bulging disc, annular tear which causes back discomfort or even a pinched nerve. Once this image is produced, your doctor will examine it for any anomalies to diagnose your condition. The generated MRI scan image depicts anatomy by distinguishing between tissues with a lot of water (such as cerebrospinal fluid or discs) and tissues with little water (such as skin, bone, cartilage, and nerve roots). Once the magnetic field is removed, the hydrogen atoms return to their usual resonance state and they release a small quantity of energy which the scanner may detect to produce the image known as the MRI scan. The device then rotates a magnet around a patient’s body, changing the level of excitation of hydrogen atoms within tissues in the patient’s body. What Your Doctor Might DoĪfter your doctor orders your MRI, the technician conducting your MRI will place you in a tube-like device. MRIs are useful for diagnosing herniated discs and bulging discs in the neck and back. If the MRI results indicate a herniated disc, your doctor may recommend additional tests to evaluate the condition better. One of the most common ways they are used is to identify the location of the herniated disc(s) in the spine and the degree of nerve compression. MRI scans are often used to diagnose and monitor herniated discs. What Is a Herniated Disc MRI and When You Might Need One Table of Contents: Primary Item (H2) Sub Item 1 (H3) Sub Item 2 (H4) MRI is considered the gold standard in medicine for evaluating disc injuries. MRI scans provide highly accurate representations of spinal discs and problems going on in and around the discs such as inflammation and degeneration. CT scans are best for looking at spinal alignment and bony issues as seen with spine fractures. CT scans use harmful x-rays and have far less accuracy because of factors that reduce visibility of the soft tissue structural changes seen with a herniated disc. Because the spatial resolution of spinal anatomy can be defined to 0.5mm with an MRI scan, doctors can identify with over 95% accuracy the herniated discs in the spine. MRI scan is the best non-invasive test available to find herniated and bulging discs and annular tears. Patients who complain of experiencing symptoms related to herniated discs are often advised to get an MRI scan done first. MRI scans of herniated discs are a helpful test used to determine the exact location and condition of the problem. MRIs are useful in many aspects of medicine, and especially so in investigating conditions of the spine. With the aid of the MRI, surgeons can accurately evaluate and diagnose conditions that could otherwise be life-altering. Magnetic Resonance Imaging (otherwise known as MRI) is one of the most important inventions in modern medicine.
