Table 1 Comparison of nodule identification

Identified nodules	Index SDCT	Study SDCT	ULDCT
Solid nodules	94	98	100
Ground glass opacities	5	4	5
Calcified granulomas	10	11	14
Part solid nodules	4	3	3
Total	113	116	122

Comparison of nodule identification between the index standard dose computed tomography (SDCT), study SDCT and ultra-low dose computed tomography (ULDCT) chest imaging protocols. This table demonstrates minimal variability between protocols with ULDCT identifying slightly more solid pulmonary nodules than the SDCT. This discrepancy did not reach statistical significance. SDCT: Standard dose computed tomography; ULDCT: Ultra-low dose computed tomography.
