Absolute Differences Between Radiologists and Semi-automated Measurements

a Radiologist vs Radiologist Measures
Measure	Mean Absolute Difference, mm	SD, mm	Minimum Difference, mm	Maximum Difference, mm	P
BWT-max	1.12	1.34	0.10	4.60	0.375
DIL-max	2.67	1.98	0.10	6.98	0.045
LUM-min	0.41	1.80	0.01	5.64	0.204
b Semi-automated vs Mean Radiologist Measures
Measure	Mean Absolute Difference, mm	SD, mm	Minimum Difference, mm	Maximum Difference, mm	P
BWT-max	1.26	1.95	0.20	6.70	0.857
DIL-max	2.78	1.81	0.07	6.90	0.557
LUM-min	0.54	1.90	0.02	6.14	0.596

_aAbsolute differences between paired radiologist measures are shown. P values listed reference the comparison of mean difference between radiologists to identify potential systematic measurement bias.

_bDifferences between semi-automated measurements and mean radiologist measurements are shown. P values shown reference the paired comparison of the difference between automated and mean radiologist measurement versus the measurement difference between radiologists for the same imaging study.
