Comparison of 12-bit and 8-bit gray scale resolution in MR imaging of the CNS : an ROC analysis

A reduction in gray scale resolution of digital images from 12 to 8 bits per pixel usually means halving the storage space needed for the images. Theoretically, important diagnostic information may be lost in the process. We compared the sensitivity and specificity achieved by 4 radiologists in read...
