Improved lesion detection from spatially adaptive, minimally complex, Pixon ® reconstruction of planar scintigraphic images

Pixon ® noise reduction was applied to 18 planar images, six each from 99mTc-methylene diphosphonate ( 99mTc-MDP), 67Ga citrate ( 67Ga), and 123I-metaiodobenzylguanidine ( 123I-MIBG) studies. Pixon processing increased patient signal-to-noise ratio, 6.8–11.8 fold. Three specialists preferred process...

Zusammenfassung:Pixon ® noise reduction was applied to 18 planar images, six each from 99mTc-methylene diphosphonate ( 99mTc-MDP), 67Ga citrate ( 67Ga), and 123I-metaiodobenzylguanidine ( 123I-MIBG) studies. Pixon processing increased patient signal-to-noise ratio, 6.8–11.8 fold. Three specialists preferred processed images 44 of 54 times with good agreement (87%). Most (9/10, p
