This research aims to assess the effectiveness of Q.Clear reconstruction methods for brain PET/MR imaging in epileptic patients.
Compared the Q.Clear reconstruction with OSEM
Evaluated three attenuation correction (AC) methods: ZTE-AC, PH-AC, Atlas-AC
Measured lesion contrast and background noise levels
ZTE-AC provided the highest lesion contrast and lesion-to-background ratio (LBR)
PH-AC resulted in the lowest background noise
Atlas-AC showed balanced but suboptimal performance

Resumen

Q.Clear reconstruction can improve lesion contrast and reduce noise compared to OSEM. ZTE-AC yielded the highest lesion contrast and LBR among three AC methods, PH-AC resulted in the lowest background noise, and Atlas-AC showed balanced but suboptimal performance. These findings offer practical guidance in selecting the suitable β value and AC method for optimized brain PET/MR imaging in patients with epilepsy.
