Sources of error in lung densitometry with CT.

Investigative radiology - 1 Apr 1999

Stoel B C, Vrooman H A, Stolk J, Reiber J H

Abstract excerpt

RATIONALE AND OBJECTIVES: To determine and analyze the most important error sources in lung CT densitometry in vivo. METHODS: The authors examined the influences of CT acquisition errors, physiologic changes, and image segmentation errors on lung densitometry. Among others, spatial dependency and long-term reproducibility of the density measurements of blood and air were examined over a period of 4 years in a...
