A method to assess image quality for Low-dose PET: analysis of SNR, CNR, bias and image noise

BACKGROUND: Lowering injected dose will have an effect on PET image quality. In this article, we aim to investigate this effect in terms of signal-to-noise ratio (SNR) in the liver, contrast-to-noise ratio (CNR) in the lesion, bias and ensemble image noise. METHODS: We present here our method and pr... View More
