Of 214 children with malignant tumours admitted in the Children’s Hospital between 1987 to 1991, six (2.8%) had spinal cord compression. The diagnosis and levels of spinal cord compression were substantiated by Omnipaque myelography in all patients. Location of the lesion was confirmed by laminectomy. Biopsy and histopathology were done to confirm the tumour types. Spine roentgenography as well...

The side effects of iohexol were evaluated in the 300 patients who had nonemergency myelography over a 9 month period. No patients studied with myelography were excluded from the iohexol trial. Age range was 14-86 years. Introduction was by lumbar puncture in 206 patients and by lateral C1-C2 injection in 94. Side effects, including discomfort, were denied by 81.3% of the patients. The other 18...

In a prospective double blind randomised study in 25 consecutive patients a conventional ionic contrast medium (Urografin 370) was compared with the new non-ionic medium iohexol 350 ( Omnipaque ) in left ventriculography and coronary arteriography. In left ventriculography there was a clear patient preference for iohexol by both a visual analogue scale and independent observer assessment. Iohex...

Background: Medical diagnostic procedures such as X-ray and computed Tomography (CT) scan account for considerable percent of patient's exposure to ionizing radiation. The exposure of cells to Ionization radiation results in induction of DNA damage and chromosomal aberrations. Contrast media (CM) are widely used in diagnostic radiology and CT scan. The aim of this study was to study adverse gen...

Iodixanol (Visipaque, Nycomed, Oslo, Norway) is an iodinated contrast medium in the form of a non-ionic dimer which is iso-osmolar with plasma at all iodine concentrations. There is little evidence regarding its renal tolerance in renal impairment. We therefore undertook a prospective randomized comparison of iodixanol and the non-ionic monomer iohexol (Omnipaque, Nycomed, Oslo, Norway). The se...

Both procedures used iodinated contrast media, iohexol (Omnipaque 350; GE Healthcare) in this case. The cause of the “floating gel” was an increase in serum density from residual contrast dye still present in the catheter used for the procedures (1 ). Laboratory tests should not be performed, even if the serum is extracted from beneath the gel barrier. The effect of residual dye is unknown, but...

A46-year-old man presented to our hospital with dyspnea and pyrexia. He was clinically thought to have a pulmonary embolus. A computerized tomography scan of the thorax (Figure 1) was acquired using a Picker MX 8000 multidetector scanner and our pulmonary embolus protocol: 3-mm collimation, pitch 1:1, and 120 mL of Omnipaque 300 as the intravenous contrast medium, delivered at a rate of 3 mL/s....
