what the risks are --> mri scans, skeletal spine, vertebra, lumbar, low back, vertebra, thoracic, mid back, posterior spinal anatomy, magnetic resonance imaging, spine, nuclear magnetic resonance, spine, mri, the spine, nmr, spine, magnetic resonance imaging, mri, the spine, noninvasive procedure, uses powerful magnets, radio waves to create pictures, the components that make up the spine, the vertabrae, spine bones, spinal cord, spaces between the vertebrae, the nerves travel, unlike conventional radiography, ct imaging, uses radiation, x-rays, passing, a patient to generate images, mri, the magnetic properties of atoms, mri scans differentiate between organs, potentially, provide contrast between benign, non-cancerous, malignant, cancerous, tissue, the images collected, stored, computer, printed on film, mri, clothing, bones, certain types of metal, around the area under investigation, cause significant errors, artifacts, images, mri makes use of radio waves very close in frequency to those of ordinary fm radio stations, scanner must be located, a specially shielded room to avoid outside interference, lie on a narrow table which slides into a large tunnel-like tube, the scanner, an iv, in the patient's hand, forearm, contrast medium to be given, a technologist, operate the machine, observe, entire study, adjacent room, several sets of images, each taking from 2-15 minutes, a complete scan, take up to 1 hour, newer scanners, complete the process in less time, , the strong magnetic fields, displace, disrupt the action of implanted metallic objects, should not be scanned, cardiac pacemakers, implanted pacemakers should not enter the mri area, inner ear, cochlear, implants, brain aneurysm clips, certain artificial heart valves, older vascular stents, placed artificial joints, sheet metal workers, persons, similar potential exposure to small metal fragments, first be screened, metal shards, the eyes, x-rays, the skull, sign a consent form confirming that none, above apply, the study, a hospital gown recommended, patient allowed to wear clothing, metal fasteners, infants, children, test depends on child's age, prepare child, infant test, procedure preparation, birth to 1 year, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years, generally, no pain associated, mri, uncomfortable, inside the scanner, feel claustrophobic, table hard, cold, request a blanket, pillow, machine produces loud thumping, humming noises, normal operation, ear plugs, patient to reduce the noise, a technologist observes the patient, entire procedure, spoken to, an intercom, in the scanner, mri scanners, equipped, televisions, special headphones to help time pass, scan, excessive movement, blur mri images, certain image errors, patient has difficulty lying still, very anxious, an oral, intravenous sedative given, no, no need, recovery period, sedation was necessary, after an mri scan, resume normal diet, medications, spine mri, exact location of tumors, lesions, the spine, spinal cord, intervertebral disks, provides detailed pictures of hard-to-view areas, the spine, the spinal canal, bony segments, soft tissue, mri is sometimes, avoid the dangers of exposure to contrast dye, radiation, spine mri performed, trauma setting to rule out acute compression, the spinal cord, in the setting of weakness, paralysis, mri is also superior to ct, in the evaluation of abscesses, tumors, masses near the spinal cord, ct is better at detecting fractures, the vertebrae, mri, detect subtle changes, in the bone, due to infection, tumor, spine mri, reveal disorders, spinal cord compression, syringomyelia, cervical disk disorders, lumbar disk disorders, tumors, the spine, enlarged lymph nodes near the spine, degenerative lesions, the spinal cord, herniated disk, additional conditions under which the test performed, multiple sclerosis, myelomeningocele, children, sensitivity of mri depends, in part, on the experience, the radiologist, no ionizing radiation involved in mri, have been no documented significant side effects, the magnetic fields, radio waves used on the human body to date, most commonly used mri intravenous contrast agent, gadolinium, very safe, have been documented allergic reactions to it, has been an extremely rare occurrence, sedation is used, associated risks of over-sedation, technologist monitors the patient's vital signs, heart rate, respiration, the effects of strong magnetic fields on a fetus, not well documented at this time, pregnant women, advised to avoid mri scans.
