Once in a while a study is published that could mark an important step forward but, at the
same time, is long overdue. The study by Schäfers et al.(1) in this issue of The Journal of …

REPLY: We thank the authors for their interest in our recent paper (1) reporting the dynamic
range of current 3-dimensional PET systems and the corresponding weight-based dose …

Dear Sir, We read with interest the article by Lassen et al.[1], in which the authors evaluated
the frequency of system saturation for fixed dose 82Rb 3D PET dynamic imaging, and the …

We compared 2-dimensional (2D) and 3-dimensional (3D) 82Rb PET imaging in 3 different
experiments: in a realistic heart–thorax phantom, in a uniformity-resolution phantom, and in …

Systems for Accurate Quantification of Myocardial Blood Flow”(1). The authors describe a
method to obtain the maximum injected activity for which accurate quantification of …

3D-PET (Positron Emitter Tomography) is widely used for quantification of myocardial blood
flow. Quantification of myocardial blood flow is very important for enhancement of the …

The purpose of this study was to assess a 3-dimensional (3D)-only PET scanner (ECAT
EXACT3D) for its use in the absolute quantification of myocardial blood flow (MBF) using …

PET imaging technology allows for absolute and relative myocardial blood flow analysis. In
addition to the well-known positron emissions resulting in the production of annihilation …
