Table 4 Clustering (%) represents the degree of voxel clustering for all lesions, for the three time points: baseline, 7 days post-therapy and 28 days post-therapy. Voxels are more clustered when the percentage is closer to 100%

From: Validation of [¹⁸F]FLT as a perfusion-independent imaging biomarker of tumour response in EGFR-mutated NSCLC patients undergoing treatment with an EGFR tyrosine kinase inhibitor

Patients	Clustering (%)
	Baseline	7 days post-therapy	28 days post-therapy
1	67.8	54.3	67.8
2	62.1	77.1	73.9
3	67.4	66.7	72.7
4	51.5	49.0	78.2
5	61.6	–*	75.8
6	44.2	83.8	80.3

*TBF data for patient 5 was unavailable and therefore the clustering parameter could not be determined
