The glucose metabolism effects of six hour exposures to subarachnoid injections of metrizamide, iohexol, iodixanol and control solutions were studied in vivo in 18 rabbits. The brain tissue uptake of intravenously injected 14C labelled deoxyglucose was measured using autoradiographic techniques. Metrizamide and iodixanol caused significant (p less than 0.05) decreases in deoxyglucose uptake in the outer cortical areas where the contrast medium concentrations were highest. Iohexol and the control CSF solution did not cause significant effects. The results appear to indicate that iohexol has less effect on brain tissue glucose metabolism than either metrizamide or the new non-ionic dimer iodixanol.

The effects of x-ray contrast media on signal intensities were studied. Relaxation times of myelographic contrast media were measured. Whereas relaxation times of Amipaque were longer, compared to CSF, the relaxation times of Duroliopaque, Omnipaque und Solutrast were significantly shorter than that of CSF. Therefore, the qualitative and quantitative effects of different contrast media on signal intensities varied. Most notable was the increase of signal intensity on T1-weighted images due to oily contrast media.

Iohexol containing 180 mg I/ml was used in 20 patients for lumbar myelography. By using an adequate volume up to a maximum of 15 ml, satisfactory films were obtained in all cases. Minor or moderate adverse effects occurred in 4 patients. There were no changes in vital signs or neurologic examination related to the examinations. No patient had difficulty with concentration, personality changes or seizures. Later encephalographies performed in all patients before and during 24 h after the iohexol injections, showed no seizure or abnormal activity or any significant change. Repeated lumbar puncture was performed in 9 patients 24 h after the injection of iohexol. One of these, a patient with symptoms due to disc prolapse, whose CSF was abnormal before the myelography, had a slightly increased cellular response. There was no significant change in any of the other patients. Iohexol is a very satisfactory contrast medium for myelography and compared favorably with other non-ionic contrast media.

Iohexol containing 180 mg I/ml was used in 80 patients for myelography by lumbar injection. By using an adequate volume, between 10 and 20 ml, satisfactory films were obtained in all cases. Minor adverse effects occurred in 12 patients (15%) and were more frequent in women than men; they were headache (5), nausea (3), vomiting (2), back or limb pain (5), and skin rash (1) and were of minor degree in 10 cases, moderate in the other two and lasted more than 24 h in only one case. There was no change in vital signs or neurological examination related to the studies. No patient suffered difficulty with concentration, personality change or seizures. Electroencephalograms performed on 21 patients before and during the 24 h after iohexol showed no seizure or focal activity or any significant change. Repeat lumbar punctures were performed on ten patients during the 24 h following myelography. One of these, a patient with symptoms due to disc prolapse, whose CSF was abnormal prior to the myelogram, showed a slightly increased cellular response. There was no significant change in any other case. Iohexol is a very satisfactory contrast medium for myelography and compares favourably with other non-ionic contrast media.

The results of 25 functional lumbar myelographies with iohexol are reported. The image quality was good or excellent in all. The side effects were mostly mild and showed the same frequency as reported in lumbar and thoracic myelographies with metrizamide. A slight increase in the frequency of side effects was found in 13 patients with spinal repuncture 6 or 24 hours after the myelography. Vacuolized monocytes in ultracentrifuged CSF following repuncture was found in 5 patients. No EEG changes or serious complications were found. Iohexol is considered safe in intrathecal use.

This is a report of the first clinical trial with iohexol in lumbar myelography. The investigation was carried out as an open, non-comparative study in 30 patients and was part of a multicentre trial. Iohexol doses of 10 to 15 ml (180 mg I/ml) were used and clinical and laboratory tests were performed before and during 48 h after myelography. Spinal repuncture 6 or 24 h after myelography was done in all patients. Only minor side effects of temporary duration were recorded in 8 patients. No seizures or spikes on EEG were seen. There was no significant increase in CSF parameters such as white cell counts, protein or IgG.
