Qualitative motion artifact was significantly less in the liver PET compared to the three other PET reconstructions (Table 1, p values ranging from <0.001 to 0.03).
The authors demonstrated the lower efficacy of [11C]choline PET compared to that of [18F]FDG PET for tumour detection and therapy response assessment in vivo after surgical castration.
When normalizing to the white matter, the relative regional grey matter COV was nominally lower with PET compared to CT in 10 of 14 ROIs.
The aim of this study was to evaluate the reliability of MO-PET compared to conventional PET segmentation methods for measuring 18F-FDG (FDG) PET metabolic tumor volume (MTV) in patients with soft tissue sarcoma (STS).
There was significantly larger Volisocontour with the liver PET compared to the WB PET likely due to the numerous breath-holds performed during the dedicated liver imaging (25%% greater, p = 0.009).
Stegger et al. were the first to quantify LV volumes and ejection fraction using FDG-PET compared to MRI [12], both in healthy mice and in mice with permanent (ICM) or transient LAD ligation.
While the limited spatial resolution of PET (compared to, e.g., MRI and CT) is a potential barrier for performing such a comparison, it certainly must be addressed to determine if such a promising approach is viable.
Visual PET compared to CIM revealed higher sensitivity (3/4 vs 1/4) and NPV (6/7 vs 10/13), and equal PPV (3/9 vs 1/3), but lower specificity (6/12 vs 10/12) and accuracy (9/16 vs 11/16).
Preliminary evaluation of PET/CT has suggested that this technology further improves on the already superior performance of stand-alone PET compared to CT [ 45].
