Myelography is a form of imaging intended to evaluate the subarachnoid spaces within the spinal canal. It is now usually performed with either CT or MR imaging of the spine after injection of an intrathecal iodinated or gadolinium-based contrast Description myelography. Myelogram – X-ray test, which uses a special radiopaque substance to take pictures of the spinal cord. Together with the X-ray, contrast agent can help the physician to clearly define the space, which contains the spinal cord and nerves. Roentgen – test, which uses X-rays, to take pictures of structures inside the body.
CT Myelography of Calcified Thoracic Neurilemoma P. E. Dross1 and M. R. RaW Radiographic demonstration of calcification within spinal canal tumors is rare . The most common lesion of this type showing calcification is a meningioma. Other lesions showing calcification include neurofibromas, hemangioblastomas, neu Myelography with air was suggested by DANDY in 1919. In the be- ginning only small quantities were used for the diagnosis of complete block. The method was unreliable, however, partly due to the difficulty in producing good radiographs with the technical equipment then avail- able. to be appropriate for the safe and efficient performance of myelography. yelography is an important diag-nostic procedure for specific in-dications, although its frequency has declined over the past decade as MRI has gained widespread acceptance for most spinal studies.
Omnipaque 180 (180 mgI/mL). Lumbar Myelography, via lumbar injection 10-17 mL; Cervical Myelography, via C1-C2 injection: 7-12.5 mL Lumbar myelography-injection is made between caudal lumbar vertebrae, ideally L5-6 in dogs and L6-7 in cats. The amount Assess using "Roentgen signs".

There were 51 men and 49 women. Five hundred intervertebral segments were observed (the five lumbar intervertebral segments from L1/2 to L5/S1 for each patient). Myelography Procedure 1. myelography - roentgenography of the spinal cord to detect possible lesions (usually after injection of a contrast medium into the subarachnoid space)
ABSTRACT. A patient is described who developed an acute, occult, lumbosacral nerve root meningocele following a partial traumatic avulsion of the L-4 and L-5 nerve roots accompanied by fracture of the pelvis and fibula. Almost total functional recovery ensued. The differences between acute and chronic nerve root meningoceles are discussed, as
Lipiodol ® (also known as ethiodized oil) is an oil-based iodinated contrast medium that was historically used for myelography and hysterosalpingography 1.It was later superseded by newer, less hazardous, agents, and now is used primarily as a therapeutic agent.
ABSTRACT. Review of more than 1400 positive-contrast myelograms of the posterior fossa performed at the Mayo Clinic indicates that this is an excellent method for depicting normal and pathological anatomy in the basal cisterns, if an adequate amount of medium and a precise technique are used. sitting lumbar myelography (SM) and standing myelography with extension (SME). The age of patients ranged from 22 to 91 years, the average age was 62.3 years. There were 51 men and 49 women. Five hundred intervertebral segments were observed (the five lumbar intervertebral segments from L1/2 to L5/S1 for each patient). Myelography Procedure 1.
Between 1975 and 1982 over 2000 metrizamide myelograms were obtained. Since January 1983 all myelograms have been obtained with iohexol. © American Roentgen Ray Society Myelography of Spinal Block from Epidural Tumor: A New Approach 121 Eleven patients with spinal canal block from metastatic epidural tumor, documented with Pantopaque myelography, were given an additional injection of up to 5 cc of air. This technique forced contrast material past the block in 10 of 11 cases.

The results of this study show that a majority of practitioners screens patients for use of potentially epileptogenic drugs, but a majority does not require patients to discontinue use of metformin and aspirin or other NSAIDs Based on experience in 541 consecutive myelographies performed in prone position, a technique is described to achieve painless myelography with faultless injection and near total recovery of Pantopaque. A newly designed aspiration cannula proved highly efficient in contrast medium recovery. In 54 cases analysis confirmed near total recovery of contrast medium.

Myelography. 3. Ett myelogram, även känt som myelografi, är ett förfarande som kombinerar användningen av färgämne med röntgen eller CT-undersökningar för att undersöka Dessa tester kan inkludera grundläggande röntgenstrålar och eventuellt ett myelogram, som är en röntgen efter att ett färgämne har injicerats i röntgen för ryggsmärta. Två typer av röntgenstrålning används på baksidan: diskografi och myelogram. En diskografi kräver injektioner i skivor Myelogram. Myelogrammet är en röntgen, med en extra twist.
(C) MYELOGRAPHY is the least performed special procedure in a piatrie neuroradiologic practice. In 1970, 95 myelograms, 9% of 1050 roentgen procedures (cerebral arteriograms, pneumoencephalograms, air and oil ven- triculograms, and myelograms), were performed at The Hospital for Sick Children in Toronto. For thoracic myelography, 12-15 ml of metrizamide at a concentration of 210 mg Il ml was used. The contrast medium was allowed to flow from the lumbar to the thoracocervical junction. For cervical myelography, 6-10 ml of metrizamide at a concentration of 300 mg Il ml was routinely used.
