Fig. 4From: A novel statistical analysis method to improve the detection of hepatic foci of 111In-octreotide in SPECT/CT imagingGraphical representation of the increased threshold index (ThI) delay for ten octreotide(+) livers (red curves). a The dashed red lines denote livers with a large tumour burden; red lines indicate livers with a minor tumour involvement. The green lines represent five octreotide(−)/radtech(−) livers. b The t scores for octreotide(+) livers (n = 10) and octreotide(−)/radtech(−) livers (n = 40) were plotted against the normalized number of uptake foci (nNUF). The two lines show the t scores for NUF values on either side of the maximum of the nNUFTI curve; the lower, dashed, light blue line shows values to the left of the curve maximum, and the higher, dark blue line shows values to the right of the peakBack to article page
