MORPHOMETRY FOR EARLY MONITORING OF TREATMENT RESPONSE IN RHEUMATOID ARTHRITIS.
New aggressive therapeutic options have recently become available to treat inflammatory arthritis (IA) and rheumatoid arthritis in particular. These treatments not only control joint destruction, they may also aid in new bone formation at sites of eroded bone. Separation of non-responders from responders to these treatments, is critical, and is kno...

Positron emission tomography in male violent offenders with schizophrenia.
Published in Psychiatry Research
The FDG PET brain scans from 31 offenders with schizophrenia and schizoaffective disorder from a maximum security mental hospital were compared with those of normal controls (N = 6) in terms of relative FDG uptake in a range of regions covering frontal and temporal regions. The patient sample was divided into those who had a history of repetitive v...
Spontaneous Coronary Artery Dissection following Topical Hormone Replacement Therapy.
Published in Case Reports in Cardiology
Spontaneous coronary artery dissection is a rare condition, usually presenting as an acute coronary syndrome, and is often seen in states associated with high systemic estrogen levels such as pregnancy or oral contraceptive use. While topical hormonal replacement therapy may result in increased estrogen levels similar to those documented with oral ...
Randoms variance reduction in 3D PET.
Published in Physics in Medicine and Biology
In positron emission tomography (PET), random coincidence events must be removed from the measured signal in order to obtain quantitatively accurate data. The most widely implemented technique for estimating the number of random coincidences on a particular line of response is the delayed coincidence channel method. Estimates obtained in this way a...
Algorithms for calculating detector efficiency normalization coefficients for true coincidences in 3D PET.
Published in Physics in Medicine and Biology
Accurate normalization of lines of response in 3D PET is a prerequisite for quantitative reconstruction. Most current methods are component based, calculating a series of geometric and intrinsic detector efficiency factors. We have reviewed the theory behind several existing algorithms for calculating detector efficiency factors in 2D and 3D PET, a...
Does pre-transplant in vitro detection of anti-endothelial cell antibodies predict renal allograft outcome?
Published in The Egyptian journal of immunology / Egyptian Association of Immunologists
Endothelial cells lining the vasculature proved to be the target for immune-mediated assault, conceivably through the so-called anti-endothelial cell antibodies (AECA). The aim of this work was to detect the AECAs, and to show its correlation with kidney allograft rejection and graft survival. The study included 60 patients who underwent live-donor...
