“…Since the risk of CI-AKI is known to be dose-dependent[3], the goal would be to keep the dose of contrast medium to a minimum. Additionally, a reduction in contrast medium dose can lower the cost by about 15% per scan, which is in line with figures cited in a related study[10]. …”

AIMTo evaluate the feasibility of reducing the dose of iodinated contrast agent in computed tomography pulmonary angiography (CTPA).METHODSOne hundred and twenty-seven patients clinically suspected of having pulmonary embolism underwent spiral CTPA, out of whom fifty-seven received 75 mL and the remaining seventy a lower dose of 60 mL of contrast agent. Both doses were administered in a multiphasic injection. A minimum opacification threshold of 250 Hounsfield units (HU) in the main pulmonary artery is used for assessing the technical adequacy of the scans.RESULTSMean opacification was found to be positively correlated to patient age (Pearson’s correlation 0.4255, P < 0.0001) and independent of gender (male:female, 425.6 vs 450.4, P = 0.34). When age is accounted for, the study and control groups did not differ significantly in their mean opacification in the main (436.8 vs 437.9, P = 0.48), left (416.6 vs 419.8, P = 0.45) or the right pulmonary arteries (417.3 vs 423.5, P = 0.40). The number of sub-optimally opacified scans (the mean opacification in the main pulmonary artery < 250 HU) did not differ significantly between the study and control groups (7 vs 10).CONCLUSIONA lower dose of iodine contrast at 60 mL can be feasibly used in CTPA without resulting in a higher number of sub-optimally opacified scans.

“…Therefore, the optimal delay for cerebral CTA using a small volume of CM with the test bolus method will be investigated quantitatively and qualitatively. Regarding CM volume, there have been two reports using a 16-MDCT system with 50 ml of CM at 3.0 ml s 21 with the bolus triggering method [15,16]. The present study with a 64-MDCT system using 40 ml of concentrated CM at 4.0 ml s 21 provides greater arterial attenuation and less venous overlap than those in previous reports.…”
