Table 2 Pre and post RDN differences in quantifications of 123I–mIBG uptake (n = 21)

From: Renal sympathetic nerve activity after catheter-based renal denervation

  PRE-RDN POST-RDN p value
Planar GM images
 Uptake 15 min 3.08 [2.79–4.95] 3.47 [2.26–5.53] 0.289
 Uptake 4 h 1.64 [1.44–1.98] 1.52 [1.12–2.27] 0.876
 % Injected dose 15 min* 17.88 [17.88–21.75] 15.43 [13.73–22.13] 0.881
 % Injected dose 4 h* 8.91 [8.91–13.52] 9.37 [7.20–12.35] 0.681
 Washout 15 min-4 h (%) 41.53 [28.26–56.25] 42.69 [35.02–56.16] 0.230
SPECT-CT images
 Uptake CT 4 h 1.41 [0.95–1.86] 1.07 [0.73–1.69] 0.526
  1. Data are presented as medians with interquartile ranges (IQR 25–75%). RDN = Renal denervation, GM = geometric mean images, with muscle as background, SPECT = single photon emission computed tomography. n.a. = not available, *data from n = 20 patients since in one patient a 123I–vial was not included during the scintigraphy and therefore the percentage of injected dose 123I–mIBG could not be calculated
