Literature data on the diagnostic performance of phlebography, myelography, and CT scan applied to patients with suspected lumbar disk herniation (LDH) are analyzed to extract maximal information about their relative discriminatory power. Seventeen papers meeting the selection criteria contain 13 reports on myelography, 6 on phlebography, and 5 on CT. Sensitivity and specificity are considered simultaneously in logistic ROC space. The reports of each procedure are effectively summarized by a linear regression in logistic ROC space. Taking into account the individual confidence regions of sensitivity and specificity obtained from each report, the slope of the regression line is estimated by Generalized Least Squares (ML). This approach also allows to test the assumption of a common odds ratio (i.e., of a unit slope). The simply to determine common odds ratio as well as the perpendicular distance between the origin and the regression line (as a good approximation to the area under the ROC curve) are used as a measure for the discriminatory power of the procedures. For CT, homogeneity of sensitivity turns out to be much more likely than a common odds ratio. Based on the available, retrospective data, phlebography appears to have the highest performance in visualizing an LDH, followed by myelography and CT.

The results of lumbar myelography and computed tomography (CT) were compared in 51 consecutive patients with clinically suggested lumbar disc herniation. A total of 100 intervertebral levels were examined. At 62 levels, either L4/L5 or L5/S I, myelography was normal. CT showed no pathologic changes at 55 levels. The results concurred between myelography and CT in 89 per cent of the patients with normal findings. Four cases of disc herniation and one bulging disc, which had been missed at myelography because of a large epidural space at L5/S I, were picked up by CT. Two of these were verified by surgery and two were treated conservatively. There was one possible false negative case with CT as well. Abnormalities were shown at 38 intervertebrallevels, 22 in the bulging and 16 in the herniated disc group. The pathologic changes concurred in 84 per cent between the two investigations. For intervertebral disc herniation the true negative rate was, for myelography 88 per cent and for CT 97 per cent. The treatment strategy could have been based on CT alone at 37 out of 38 levels (97%), and on myelography alone at 34 out of 38 levels (89%). Furthermore, at CT the imaging of soft tissues and intervertebral joints was superior to that at myelography. It is concluded that CT should be the primary examination method of imaging for lumbar disc herniation. Myelography is, however, to be preferred where the level of the lesion is clinically unclear or when the entire lumbar region and thoraco-lumbar junction are to be examined.

We report a retrospective study of 219 patients with lumbar disc lesions in whom the operative findings were compared with the results of computer tomography (CT) and myelography. When used alone each method achieved virtually the same degree of accuracy (87.8% and 87.4%). Particular attention was paid to 70 "problem" cases in whom the initial CT diagnosis suggested herniations at different levels which were not in keeping with the clinical symptoms or signs. The operative findings showed that CT had produced 10.4% false positives and 4.4% false negatives. The corresponding results for myelography were 5.9% and 8.9%. Myelography is, therefore, a more exact method of diagnosis for segmental and lateral herniations. After initial computerised tomography, myelography is indicated when there is a discrepancy between CT and the clinical findings.
