Evaluating the Accuracy of 4D-CT Ventilation Imaging: First Comparison with Technegas SPECT Ventilation.

CONCLUSION: We performed a validation of CTVI using clinically available 4DCT and Technegas V/Q-SPECT for 11 lung cancer patients. The results reinforce earlier findings that the spatial accuracy of CTVI exhibits significant inter-patient and inter-method variability. We propose that the most likely factor affecting CTVI accuracy was poor image quality of clinical 4DCT. This article is protected by copyright. All rights reserved.
