Twenty-four patients with liver tumor were included in this study. All patients underwent Gd-EOB-DTPA-enhanced-MRI and Tc-99m-GSA hepatic scintigraphy. Clearance index (HH15) and receptor index (LHL15) were calculated for the Tc-99m-GSA, while signal intensities (SI) of liver at pre-injection and at 4/20min post-injection, and of spleen at 4 min/20min were measured (SIpre, SI4min, SI20min, SIsp4min, SIsp20min, respectively) for the Gd-EOB-DTPA-MRI. Liver activity at 15min by Tc-99m-GSA scintigraphy or biochemical liver function values were compared with liver spleen contrast at 4min (LSC4min = SI4min/SIsp4min) or 20min post-injection (LSC20min = SI4min/SIsp20min), and the increase in ratio at 4min (IR4min=SI4min/SIsp4min) or 20min (IR20min= SI20min/SIpre). Total bilirubin levels (T-bil), serum albumin levels (Alb), prothrombin activity, and the indocyanine green clearance test (ICG) results were also analyzed. There were statistically significant correlations in all comparisons between Gd-EOB-DTPA and Tc-99m-GSA. The highest coefficient of correlation was obtained in IR4min (LHL15: r = 0.795, P\u003c0.001; HH15: r = -0.782, P\u003c0.001), with IR20min (LHL15: r = 0.690, P\u003c0.01; HH15: r = -0.528, P\u003c0.05), LSC4min (LHL15: r = 0.458, P\u003c0.05; HH15: r = -0.626, P\u003c0.05), and LSC20min (LHL15: r = 0.443, P\u003c0.05, HH15: r = -0.609, P\u003c0.05) also significantly correlated. Correlations in hepatic function data were observed between IR4min and T-bil/Alb, and IR20min and Alb.

内容記述 | This study compared results from Gd-EOB-DTPA on two different phases of 3T MRI with those from Tc-99m-GSA hepatic scintigraphy and hepatic function tests. Twenty-four patients with liver tumor were included in this study. All patients underwent Gd-EOB-DTPA-enhanced-MRI and Tc-99m-GSA hepatic scintigraphy. Clearance index (HH15) and receptor index (LHL15) were calculated for the Tc-99m-GSA, while signal intensities (SI) of liver at pre-injection and at 4/20min post-injection, and of spleen at 4 min/20min were measured (SIpre, SI4min, SI20min, SIsp4min, SIsp20min, respectively) for the Gd-EOB-DTPA-MRI. Liver activity at 15min by Tc-99m-GSA scintigraphy or biochemical liver function values were compared with liver spleen contrast at 4min (LSC4min = SI4min/SIsp4min) or 20min post-injection (LSC20min = SI4min/SIsp20min), and the increase in ratio at 4min (IR4min=SI4min/SIsp4min) or 20min (IR20min= SI20min/SIpre). Total bilirubin levels (T-bil), serum albumin levels (Alb), prothrombin activity, and the indocyanine green clearance test (ICG) results were also analyzed. There were statistically significant correlations in all comparisons between Gd-EOB-DTPA and Tc-99m-GSA. The highest coefficient of correlation was obtained in IR4min (LHL15: r = 0.795, P<0.001; HH15: r = -0.782, P<0.001), with IR20min (LHL15: r = 0.690, P<0.01; HH15: r = -0.528, P<0.05), LSC4min (LHL15: r = 0.458, P<0.05; HH15: r = -0.626, P<0.05), and LSC20min (LHL15: r = 0.443, P<0.05, HH15: r = -0.609, P<0.05) also significantly correlated. Correlations in hepatic function data were observed between IR4min and T-bil/Alb, and IR20min and Alb. In 3T-MRI using Gd-EOB-DTPA, the SI of liver at pre- to post-injection (especially at 4 min) significantly correlated with the corresponding Tc-99m-DTPA scintigraphy results, and with some biochemical liver function data. | |||||
