Comparative Study
Evaluation of primary prostate cancer using 11C-methionine-PET/CT and 18F-FDG-PET/CT.
The objective of this study was to evaluate the capability of (11)C-methionine (MET)-PET/CT and (18)F-2-deoxy-2-fluoro-D: -glucose (FDG)-PET/CT to diagnose primary prostate cancer using recently developed Gemini TF PET/CT (Philips Healthcare, Cleveland, OH). ⋯ In terms of the capability to diagnose prostate cancer of high Gleason score (≥8), there was no significant difference between MET and FDG. MET appears to be useful for detecting prostate cancer of both low and high Gleason score.

Comparative Study
The agreement of left ventricular function parameters between (99m)Tc-tetrofosmin gated myocardial SPECT and gated myocardial MRI.
The aim is to compare and evaluate the agreement of quantification of left ventricular functional parameters obtained by two different methods, (99m)Tc-tetrofosmin gated myocardial perfusion SPECT (MPS) and cardiac magnetic resonance imaging (CMR). ⋯ In quantifying of left ventricular function parameter, gated CMR provides similar quantitative values comparing with gated MPS except for ventricular volumes in rest conditions. In contrast, there were certain variations except for LVEF in exercised examinations. When we follow patients by the same cardiac parameters with CMR and MPS, using parameters across the two modalities proved to be possible under rest condition. However, it is limited at exercise condition.
