Towards More Structure: Comparing TNM Staging Completeness and Processing Time of Text-Based Reports versus Fully Segmented and Annotated PET/CT Data of Non-Small-Cell Lung Cancer

Table 3

Descriptive statistics of diameter and segmentation time per lesion.

	Diameter (mm)			Time per lesion (min)
	T	N	M	T	N	M
Mean	18.2	12.2	13.0	5.7	2.3	2.1
Standard deviation	13.7	4.8	4.6	9.7	4.9	4.8
CI	17.1–19.3	12.0–12.5	12.7–13.3	4.9–6.4	2.0–2.6	1.7–2.5
Min	4.3	4.9	4.9	0.0	0.0	0.0
Median	12.8	11.0	12.3	2.8	1.4	1.3
Max	81.0	56.6	30.6	126.0	111.0	119.2

An overview of the time required for segmentation per lesion and the lesion diameter relative to the respective T/N/M descriptors are shown. Compared to N and M lesions, T lesions have the largest diameter and highest segmentation time. CI = confidence interval.
