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.

Introduction and aim: Dual Source CT (DSCT) scanners, with an increased temporal resolution (83 ms), are becoming widely available. To evaluate the current potential of this scanner in the clinical arena, we performed a head-to-head comparison with conventional coronary angiography (CCA) taking into account the following parameters: radiation exposure, procedure time and contrast load. Methods: During a one-year period (april 2006 to march 2007) we compared a consecutive patient group who underwent DSCT (318 patients, 222 male, mean age 68±11 years) and CCA (352 patients, 258 male, mean age 61±12) respectively. Patients with previous bypass surgery were excluded. In DSCT, the volume of iodinated contrast material was adapted to the scan time. A contrast bolus was injected in an antecubital vein at a flow rate of 5.0 ml/s followed by a saline chaser of 40 ml at 5.0 ml/s. Each tube provided 412 mAs/rot (maximum), and full X-ray tube current was given during 25–70% of the RR-interval. Exposure data were collected using the x-ray dosimetrical reports from DSCT and CCA. Results: The mean procedure time using DSCT and CCA was 16.1±4.7 min and 44.1±25.5 min (p<0.001), respectively. The mean contrast load in DSCT and CCA was 77.9±7.6 ml and 175.3±4.3ml (p<0.001), respectively. The overall radiation exposure for DSCT and CCA was calculated as 15.3±4.0 mSv and 5.7±4.3 mSv, respectively. Radiation exposure with DSCT was significantly lower (p<0.001) in patients with a heart rate of >70 bpm (12.9±3.1 mSv ) as compared with patients with heart rates <70 bpm (16.4±3.8 mSv). Conclusion: In today’s practice currently available DSCT scanners perform favorably as compared with CCA, considering procedure time and patient contrast load. Radiation exposure with DSCT remains higher but should not be considered a major disadvantage taking into account the relatively old age group that generally undergoes coronary angiography and the major benefit of not being exposed to the risks of an invasive procedure.

Contrast Enhanced

Contrast-induced acute kidney injury (CI-AKI) is commonly defined as a decline in kidney function occurring in a narrow time window after administration of iodinated contrast material. The incidence of AKI after contrast material administration greatly depends on the specific definition and cutoff values used. Although self-limiting in most cases, postcontrast AKI carries a risk of more permanent renal insufficiency, dialysis, and death. The risk of AKI from contrast material, in particular when administered intravenously for contrast-enhanced CT, has been exaggerated by older, noncontrolled studies due to background fluctuations in renal function. More recent evidence from controlled studies suggests that the risk is likely nonexistent in patients with normal renal function, but there may be a risk in patients with renal insufficiency. However, even in this patient population, the risk of CI-AKI is probably much smaller than traditionally assumed. Since volume expansion is the only preventive strategy with a convincing evidence base, liberal hydration should be encouraged to further minimize the risk. The benefits of the diagnostic information gained from contrast-enhanced examinations will still need to be balanced with the potential risk of CI-AKI for the individual patient and clinical scenario.

MRI is a non-invasive imaging technique that permits the most comprehensive study of aortic diseases. It offers morphological, functional and biochemical information. Conventional ECG-gated spin-echo imaging, cine gradient-echo and contrast-enhanced 3D MR angiography have earned MRI the reputation of being the ideal tool for evaluating the aorta. The phase-contrast imaging technique enables the assessment of flow in the great vessels. MRI can be used to define the location and extent of aneurysms, dissections and aortic wall ulceration. This is the best technique to demonstrate areas of wall thickening related to aortitis or intramural haematoma. MRI may also be used as a tool to study aortic physiology by assessment of elastic aortic properties, stiffness and aortic wall shear stress. MRI is particularly useful in patients with either contraindications to iodinated contrast material or in those with known aneurysms who require sequential follow-up.
