Axial SPECT/CT images. (a) The low-dose CT. (b) The SPECT and CT images fused. (c) Close-up of the low-dose CT. (d) The SPECT and CT images fused with the measurement of distance from the centre of activity of the 99mTc-nanocolloid to the 125I seed; the measured distance is 8 mm. The green lines indicate the same position in the different images.
