Objective(s): This study was undertaken to determine the role of computed tomography (CT)-based methodology to segment the SI joint and quantify the metabolic activity using positron emission tomography (PET). We measured tracer uptake in the right and left SI joints independently to look for differences between the two sides. Further, we correlated tracer uptake with ...
Introduction: 18F-Choline PET-CT is an increasingly used technique in patients with prostate cancer. The main indication is to localise the disease in patients with biochemical recurrence. To accurately interpret 18F-Choline PET, knowledge of normal tracer distribution is paramount. The aim of this study was to describe the normal distribution pattern of 18F-Cho...
Examinations of probabilistic tractography have identified major tracts across the brain, but little has been done to compare them to wellestablished tracer studies. Therefore, diffusion tensor imaging (DTI) probabilistic tractography of white matter (WM) was performed on a DTI template generated from 271 rhesus macaques. Injection sites from tracer experiments in literature were chosen as seed...
An asymptotic procedure is presented to evaluate the tracer trajectory in a two-stream turbulent pipe mixing unit with an oblique branch. The proposed mixing jet trajectory estimate is compared with the existing experimental data and used to calculate the critical mixing conngurations. In addition, it is shown that the well-known tracer jet proole can be recovered for the case of a normally iss...
