We consider the symbol-synchronous Gaussian Lout-of-hcode-division multiaccess channel, and obtain the capacity region and the upper and lower bounds to the symmetric capacity. The capacity region is found to be the same with or without frame synchronism. The lower bound depends on the signature waveforms through the eigenvalues of the SNRweighted(More)
BACKGROUND There have been no data with regard to the relationship between coronary artery calcification (CAC) detected with positron emission tomography (PET)/computed tomography (CT), as incidental findings, and myocardial perfusion single photon computed tomography (MPS) results in patients with cancer. OBJECTIVES The main objective of this study was(More)
BACKGROUND AND OBJECTIVES No data are available in Saudi Arabia on the relationship between coronary artery calcification (CAC) and myocardial perfusion scintigraphy (MPS) in asymptomatic women, for determining subclinical coronary artery disease (CAD). The main objective of this study was to investigate the relationship between the presence of CAC and(More)
The purpose of this study is to quantitatively compare the accuracy of spatial registration of Cartesian breath-hold 3D-GRE and non-respiratory-triggered free-breathing radial 3D-GRE images with PET data acquisition on whole-body hybrid MR–PET system. Eight patients (six men and two women; mean age, 56.6 ± 5.5 years) with nine ablated hepatocellular(More)
PURPOSE Although the overall incidence of bone metastasis is not known, over one-half of the people who die of cancer in the USA every year are thought to have bone involvement. In this study we have developed a method to quantify the metabolic and anatomic changes induced by different types of bone metastases in cancer patients using PET/CT images. (More)
