“…The complications and side effects of myelography using Pantopaque and water-soluble media are reported in the literature [3][4][5], Both oily and water-soluble con trast media are associated with the risk of subsequent arachnoiditis. One of the disadvantages of oily contrast media is that they cannot be removed completely and remain within the subarachnoid space for a long time after the examination [6], The rate of absorption of Pant opaque is estimated to be 0.5-1.0 ml/year [2], Moreover, patients with a small amount of residual Pantopaque in the posterior cranial fossa are reported to have no clinical symptoms [5], It seems possible, however, that droplets of Pantopaque for a long time in contact with nerve tissue may cause various types of neurological disturbance.…”

“…Di Chiro and Fisher ( 1964) have shown that for the lumbar region of the spine the mean radius of the spinal cord is about 0.5 cm and the mean spinal canal radius i s very close to 1.0 cm. The radius of the nerve roots is approximately 0.05 cm.…”

“…The data of Di Chiro and Fisher (1964) indicates a mean fluid cross-section in the lumbar region of about 2.4 cmz which corresponds to an equivalent circular cylinder of 0.87 cm radius. Following Johnston et al (1972) the calculation of doses from penetrating radiations was made assuming the source and target to be a long right circular cylinder of radius 0.8 cm.…”

SUMMARY Equilibrium absorbed dose contributions for radiations emitted by 169Yb have been derived and utilized in the calculation of doses to the spinal cord and nerve roots from intrathecally administered 169Yb‐DTPA. Mean doses to the whole body and gonads have also been determined and compared with doses calculated for 131I‐HSA and 99mTc‐HSA. The spinal cord pia mater surface dose from 169Yb‐DTPA is comparable to that from 131I‐HSA, while the dose at the base of the pia mater is about half that from 131I‐HSA. For an injected activity of 1 mCi the dose to the pial surface from 169Yb‐DTPA is about 70 ±30 rads and that to the base of the pia about 17 ±8 rads.

“…A ratio method of diagnosing spinal stenosis, independent of magnification factors, has been used [1, 3]. Concerning myelography, there is also an inevitable magnification factor with relation to the focus±film distance.Spinal stenosis of the lumbar spine is best determined with CT myelography; however, in the cervical spine, lordosis may create a false appearance of spinal stenosis [1,4].In our experiment, CT myelographic measurements were not used, although previous reports have been done in cervical spine [5]. The CT myelographic films were not reviewed because no sagittal equivalent view was available.…”

Quantitative measurements of the spinal cord and canal by MR imaging and myelography

et al. 1998

There is a large individual variation in human spinal cord and canal size, even in patients of different series studied by the same modality, and no authorized standard method has been established. A comparative study of sagittal diameters of the cervical spinal cord and canal using myelography and MRI is presented. The purposes of this paper are (a) to establish the correction factor (CF) needed for quantitative comparison of the two imaging modalities, and (b) to determine the different factors that may modify the measurement of these diameters. We studied 45 patients with clinical findings compatible with cervical spondilotic myelopathy. In our experience, the CF for accurate correlation of MRI and myelography measurements is 1.32 and depends almost entirely on the radiographic geometry of the myelographic procedure. In addition, there is a variability in the group of MRI results due to imprecision of the pressure-pad measuring/input device of the instrument itself and the sequence performed.
