As the size and complexity of Wireless Sensor Networks (WSN) continue to grow, there is a need to develop techniques capable of achieving a level of service with successful operations upon which users can depend on. The routing protocol plays an important role in a multihop WSN as it manages and controls the delivery of the data packets. The function of a WSN can be affected by radio anomalies ...

Introduction: Nowadays, Imaging of the myocardial perfusion (MPI) using the single photon emission tomography (SPET) in the diagnosis of coronary artery disease, especially myocardial ischemia, is of great importance. In contrast to the coronary artery angiography, MPI is non-invasive, less expensive and more physiological. Unfortunately, this image is affected by the some artifacts. Thes...

Technological Educational Institute of Athens, Greece The contributions of the present European Journal of Nuclear Medicine and Molecular Imaging Physics Proceedings issue “PSMR2014 – 3 International Conference on PET-MR and SPECT-MR” give a representative overview of oral and poster presentations at the third Conference on PET-MR and SPECT-MR.

OBJECTIVE This study was aimed to investigate the characteristics of coronary artery calcium (CAC) in Chinese population with suspected coronary artery disease (SCAD). METHODS We studied 205 Chinese patients with SCAD who were subjected to combined MPI and CAC score (CACS) study on a hybrid single photon emission tomography/computed tomography (SPET/CT) scanner. RESULTS a) Among the 205 pat...

PURPOSE Over the past decade, nuclear medicine experts have been seeking to minimize patient exposure to radiation in myocardial perfusion scintigraphy (MPS). This review describes the latest technological innovations in MPS, particularly with regard to dose reduction. METHODS We searched in PubMed for original clinical papers in English, published after 2008, using the following research cri...

Accurate prediction of in vivo hepatic drug clearance using in vitro assays is important to properly estimate clinical dosing regimens. Clearance of low turnover compounds is especially difficult to predict using short-lived suspensions of un-pooled primary human hepatocytes (PHHs) and functionally declining PHH monolayers. Micropatterned cocultures (MPCCs) of PHHs and 3T3-J2 fibroblasts have b...

Objective: To investigate the abnormal cerebral blood ow (CBF) perfusion in patients with internet addiction (IA) and its possible association with IA severity. Subjects and Methods: Thirtyve adolescents 99m who met the criteria for IA and 12 matched healthy volunteers were recruited for Tc-ethylcysteinate dimer based CBF perfusion imaging with single photon emission tomography (SPET) both at r...
