Abstract
PURPOSE: A retrospective study was performed to assess the role of iodine concentration on the opacification of different vascular compartments of the chest with a nonionic contrast agent (Iopamidol) during routine spiral CT examination. MATERIAL AND METHOD: 105 injected spiral CTs of the chest were studied. 50 examinations were done with Iopamidol 300 (iodine concentration 300 g/L) (I300). 55 examinations were done with Iopamidol 370 (iodine concentration 370 g/L) (I370). A constant 24- g total iodine dose was delivered with no difference in the injected iodine flow rates (respectively 0.6 and 0.55 g/s). Images were scored for opacification success, opacification quality and for artefacts in each vascular, of the chest. RESULTS: There was no statistically significant difference in opacification success or in opacification quality, in each chest vascular compartment between the group receiving I300 and the group receiving I370. Artefact frequencies on the lower part of superior vena cava were however different, 24% and 41.8% respectively. CONCLUSION: For a constant injected iodine flow rate, a moderate increase in iodine concentration, with decreased injection volume and flow rate, had little or no effect on opacification of the aorta and the pulmonary artery. The presence of artefacts on the lower part of the superior vena cava would suggest that the use of lower concentration contrast media would be advisable for specific vena cava examinations.
