Imaging of the spine
Imaging of the spine - a detailed scan and examination of spine.
Carry out computer tomography and magnetic resonance.
Computed tomography of spine
CT scan data is obtained by irradiating X-rays of the spine and subsequent digitization of the data.
In preparation for the examination, the patient abstains from food - 4 hours prior to imaging of the spine can not be there. Immediately prior to imaging is necessary to take off metal items (glasses, jewelery, prostheses, etc.). Those patients who are afraid of enclosed space, it is recommended to take a sedative before the test. In severe back pain can take pain medication.
During imaging of the spine tomography scanner moves around the patient and makes the desired angle shots.
Once made the first series of images, the patient is administered a contrast and a half hour watching the reaction. If there are itching, rashes, problems with breathing, imaging of the spine do not continue. If the contrast is not cause allergies, do a second series of shots.
The result of the survey is the images (tomography), in which the vertebrae are marked with white, soft cloth - gray, and cerebrospinal fluid - black. In addition, different fabric density are also distinguished by color.
Make the doctor recommends imaging the spine to determine the cause of chronic and acute back pain, assessment of the spine before and after surgery, cancer diagnosis, and metastasis in the intervertebral discs.
Magnetic resonance imaging of the spine
Magnetic resonance imaging is considered safer for health, as It does not involve radiation: action MR imaging is based on the principle of nuclear magnetic resonance.
MRI is considered the most accurate, sophisticated and sensitive method of examination of the spine.
Make spine imaging method of magnetic resonance doctor considers it necessary to assess the state of the spine as a whole, to detect diseases of the spinal tissue, postoperative changes in the spine, a condition of intervertebral discs, inflammation and pinched nerves, spinal infection, causes of back pain, tumor in the spinal cord or spinal column to determine the date of the spinal surgery.
Patient for examination are placed in a capsule, there arises an electromagnetic field, and under the action of the molecule in the human body are arranged, as well as electromagnetic waves. After that, begin the scan of the spine with the help of radio waves. Lasts imaging of the spine is not more than 20 minutes.
Magnetic resonance imaging of the spine vastly superior computer since it can help you learn more: the spine can be seen in several planes and better visualize the soft tissue.
Imaging of the cervical and lumbar spine
Indispensable magnetic resonance method of diagnosis when examining the cervical and lumbosacral. These areas are most prone to the emergence of various defects and account for the majority of the surveys of the spine.
Now MR imaging of the cervical spine, as well as imaging of the lumbar spine in the first place compared with computed tomography, X-ray diffraction.
Imaging of the cervical spine is prescribed for osteochondrosis, hernia and protrusion of the disc, spinal stenosis channel, metastatic cells at the level of cervical spine, trauma, abnormalities of the cervical syndrome (extra cervical ribs, short neck).
MR imaging of the lumbar spine doctor prescribes pass in osteochondrosis of the lumbar, hernia and protrusion, tumor metastases, hemangiomas in the spine, epidural space, the spinal cord, spinal canal stenosis, trauma.
