This study aimed to develop a new convolutional neural network (CNN) method for estimating the specific binding ratio (SBR) from only frontal projection images in single-photon emission-computed tomography using [123I]ioflupane. We created five datas

In the [123I]FP-CIT single-photon emission computed tomography (SPECT) examination, the specific binding ratio (SBR), calculated from the ratio of the striatal specific to extra-striatal background non-specific binding in the brain, is now commonly u

The heart-to-mediastinum (H/M) ratio on myocardial scintigraphy with (123)I-metaiodobenzylguanidine (MIBG) is used as a semi-quantitative index. However, the scatter from a photopeak of 529 keV on (123)I is thought to affect the H/M ratio, and collim

The undershooting artifact occurs using the filtered back projection (FBP) method. This artifact is influenced by a ramp filter. Thereby, the fall of the target accumulation and a deficit arise and it becomes a clinical problem. We developed a new im
