European Radiology, 2013Co-Authors: Hiroshi Kondo, Masayuki Kanematsu, Satoshi Goshima, Noriyuki Moriyama, Haruo Watanabe, Hiroshi Kawada, Kyongtae T BaeAbstract:To compare total Body Weight (TBW), Lean Body Weight (LBW) and Body surface area (BSA) for the adjustment of the iodine dose required for contrast-enhanced multi-detector computed tomography (MDCT) of the aorta and the liver. One hundred and three patients undergoing MDCT of the abdomen were randomised into three groups: the TBW group receiving 0.6 g iodine/kg of TBW (n = 33), the LBW group receiving 0.75 g iodine/kg of LBW (n = 35) and the BSA group receiving 22 g iodine/m2 (n = 35). ∆HU (increases in CT value) per gram of iodine (∆HU/g) and adjusted maximum hepatic enhancement (adjusted MHE; ∆HU/[g iodine/kg]) correlated with three groups using linear regressions. Correlation coefficients of ∆HU/g were 0.67 (TBW), 0.86 (LBW) and 0.85 (BSA) for the aorta, and 0.74 (TBW), 0.77 (LBW) and 0.84 (BSA) for the liver. Adjusted MHE was constant at 70.2 with LBW and at 2.69 with BSA, but correlated positively with TBW (r = 0.58, P < 0.001). Iodine load may need to be tailored by LBW or BSA in contrast enhanced MDCT of the abdomen. BSA is a simple and feasible index for the determination of iodine dose in individual patients. • Optimisation of enhancement is very important for high quality MDCT. • Iodine dose is best adjusted according to LBW or BSA. • BSA may be adopted because calculation is simple. • Iodine dose of 0.712 g/kg LBW/18.6 g/m 2 BSA gives 50 HU hepatic enhancement.

aortic and hepatic enhancement at multidetector ct evaluation of optimal iodine dose determined by Lean Body Weight
European Journal of Radiology, 2011Co-Authors: Hiroshi Kondo, Masayuki Kanematsu, Satoshi Goshima, Noriyuki Moriyama, Minoru Onozuka, Haruo Watanabe, Kyongtae T BaeAbstract:Abstract Purpose To determine the optimal iodine dose for aortic and hepatic enhancement at MDCT by comparing Lean Body Weight (LBW) with total Body Weight (TBW). Materials and methods This study was approved by our institutional review committee. One hundred and thirty-six patients were randomized into four groups: 550, 650, 750 mg iodine/(kg of LBW) and 600 mgI/(kg of TBW). The aortic and hepatic contrast enhancements (ΔHUs) during the portal venous-phase and variances of ΔHUs were compared. Results Mean ΔHUs for 550, 650, 750 mgI/kg LBW and 600 mgI/kg TBW were: 95.1, 109.9, 122.4, and 131.2 HU, respectively, for the aorta. For the liver, 43.1, 55.4, 60.8, and 63.5 HU. Mean ΔHUs increased with iodine dose per kg LBW ( p Conclusion Hepatic enhancement variation was reduced with iodine doses based on LBW. Iodine dose of 750 mg iodine/kg LBW was appropriate to achieve hepatic enhancement ≥50 HU in 94% of patients.

effect of contrast injection protocols with dose adjusted to the estimated Lean patient Body Weight on aortic enhancement at ct angiography
American Journal of Roentgenology, 2009Co-Authors: Yumi Yanaga, Kazuo Awai, Takeshi Nakaura, Seitaro Oda, Yoshinori Funama, Kyongtae T Bae, Yasuyuki YamashitaAbstract:OBJECTIVE. The objective of our study was to investigate the effect on aortic enhancement of iodine doses adjusted for the patient estimated Lean Body Weight (LBW) at CT angiography (CTA).SUBJECTS AND METHODS. CTA for the whole aorta using a 64-MDCT scanner was performed in 97 patients (mean age, 67.4 years) with confirmed or suspected aortoiliac disease. The patients were divided into two groups: a total Body Weight (TBW) group (n = 49) and an estimated LBW group (n = 48). LBW was estimated from the patient Weight (TBW) and height. The TBW and estimated LBW groups received 360 mg I/kg of TBW and 450 mg I/kg of estimated LBW of contrast medium, respectively. The relative dose ratio for the estimated LBW group versus the TBW group was based on the fact that the standard percentage of Body fat in Japanese adults with an average TBW of 60 kg is 20% (360 = 0.8 × 450). Differences in the degree of aortic enhancement and interpatient variability in aortic enhancement between the estimated LBW and TBW group were...
