Improved lesion detection in SPECT using MLEM reconstruction

Receiver operating characteristic (ROC) analysis was applied to determine if the maximum likelihood expectation maximization (MLEM) reconstruction algorithm improves lesion detectability in single photon emission computed tomography (SPECT) when compared with a filtered backprojection (FBP) algorith...
