Key result
Digital densitometry using 1024x1024 imaging provided significantly less error in vessel size determination compared to 512x512 imaging, making it preferable for absolute blood flow determination.
Why the study?

High-resolution 1024x1024 digital imaging improves the accuracy of vessel size determination, which is critical for calculating absolute blood flow using digital densitometry.
Lois et al. (1987) studied Blood flow measurement. Digital densitometry (1024x1024 imaging) vs. 512x512 imaging was evaluated on Vessel size determination and blood flow measurements. Digital densitometry using 1024x1024 imaging provided significantly less error in vessel size determination compared to 512x512 imaging, making it preferable for absolute blood flow determination.
