Twenty-two patients with lung cancer (tumor size > 2 cm) underwent DWIs (3.0 T) in three imaging methods. Lesion ADCs were measured twice by both of the two independent observers and compared.
No statistical significance was found among methods, though respiratory-triggered DWI tended to have higher ADCs than breath-hold DWI. Great inter- and intraobserver agreement was shown.
ADCs had good inter- and intraobserver agreement in all three DWI methods.
