RESUMO
Iohexol myelography was performed in 25 cases of suspected spinal cord compression. Out of these, 24 cases gave optimally informative myelogram, while one case showed quasi-informative myelogram. Myelographic efficacy regarding the level of lesion was correct in all cases. On final evaluation 15 cases were diagnosed as extradural lesions, 9 cases as intradural extramedullary type and one case as diastematomyelia. Only single case which was diagnosed as intramedullary lesion on myelography was, in fact, an extradural lesion. There were only minor side-effects in the form of headache and paraesthesia in the lower limb. It was concluded that iohexol is a safe contrast medium with high efficacy and minimal side-effects for the total examination of spinal canal.

The arthrographic examination was carried out in 25 patients with non-traumatic painful wrist of more than 6 weeks duration. Plain x-rays were non-contributory in making any diagnosis in 20 cases. Arthrography was performed even when plain x-rays were normal and it revealed the soft tissue abnormalities and early phases of cartilage destruction not visible on routine roentgenograms. The extent of synovial involvement demonstrated on arthrography proved useful when synovectomy was planned. After operation pain and swelling disappeared and functions of the joint improved considerably.
