Iodinated Contrast

Iodine containing contrast media are used much frequently now-a-days for computed tomography examinations in children. The group of non-ionic monomers occupies a special place among modern contrast agents. Low osmolarity and viscosity, electrical neutrality and the highest iodine content of these contrast materials provide the best diagnostic efficacy with minimum risk of adverse reactions. However, characteristic anatomic and physiological aspects of a growing child’s body require additional attention and care during diagnostic procedures with use of such contrast agents. This article presents concise literature review of recent years highlighting practical aspects of nonionic lowosmolar iodinated contrast material use for computed tomography assisted diagnostic examinations in child population.

PurposeClinical trials have provided evidence that treating patients with acute ischaemic stroke (AIS) beyond 4.5 hours was feasible. Among them using MRI diffusion-weighted imaging/fluid attenuation inversion response (DWI/FLAIR) mismatch to guide intravenous tissue plasminogen activator (tPA) was successful. Our study explored the outcome and safety of using DWI/T2-weighted imaging (T2WI) mismatch to guide intravenous tPA therapy for patients with AIS between 4.5 hours and 12 hours of onset.MethodThis was a retrospective study. Records of 1462 AIS patients with the time of onset of <12 hours were reviewed. Those had MRI rapid sequence study and had hyperintense signal on DWI but normal T2WI and received intravenous tPA up to 12 hours of onset were included in the analysis. Their demographics, risk factors, post-tPA complications, National Institutes of Health Stroke Scale (NIHSS) scores and outcome were recorded and analyse. χ2 was used to compare the intergroup variables. SAS was used to perform statistical calculation. A p<0.05 was considered statistically significant.ResultsOf 1462 identified, 601 (41%) patients were entered into the final analysis. Among them, 327 (54%) had intravenous tPA within 4.5 hours of onset and 274 (46%) were treated between 4.5–12 hours. After intravenous tPA, 426 cases (71%) had >4 pints of improvement on NIHSS score within 24 hours. Postintravenous tPA, 32 (5.32%) cases had haemorrhagic transformation. 26 (4.33%) were asymptomatic ICH and 4 (0.67%) died. At 90 days, 523 (87%) achieved a modified Rankin scale of 0–2.ConclusionUsing MRI DWI/T2WI mismatch to identify patients with AIS for intravenous tPA between 4.5 hours and 12 hours was safe and effective. The outcome was similar to those used DWI/PWI or DWI/FLAIR mismatch as the screening tool. However, obtaining DWI/T2WI was faster and avoided the need of contrast material.
