Introduction: One of the most important causes of death in patients with end-stage renal disease (ESRD) and even after kidney transplantation is cardiovascular diseases. Thus, cardiac evaluation is of utmost importance in the management of these patients especially during preoperative work up before renal transplantation. The aim of present study is to evaluate the role of myoc...

The Message Passing Interface (MPI) standard for programming parallel computers is widely used for building both programs and libraries. Two of the strengths of MPI are its support for libraries and the existence of multiple implementations on many platforms. These two strengths are in conflict, however, when an application wants to use libraries built with different MPI implementations. This p...

stress-only MPI SPECT (≈3 mSv), rest-stress MPI PET Rubidium-82 (≈3 mSv), and rest-stress MPI PET 13N (≈2 mSv) are represented in the recent consensus document (3). In addition, as defined by the authors, novel SPECT camera technology may allow us to reduce radiation doses with SPECT imaging (5). Stress-only MPI use may be encouraged whenever possible to reduce radiation exposure. Finally, in f...

Magnetic Particle Imaging (MPI) is a promising new tracer modality with zero attenuation deep in tissue, high contrast and sensitivity, and an excellent safety profile. However, the spatial resolution of MPI is limited to around 1 mm currently and urgently needs to be improved for clinical applications such as angiography and brain perfusion. Although MPI resolution is highly dependent on trace...

The symmetric multiprocessing (SMP) cluster system, which consists of shared memory nodes with several multicore central processing units connected to a high-speed network to form a distributed memory system, is the most widely available hardware architecture for the high-performance computing community. Today, the Message Passing Interface (MPI) is the most widely used parallel programming par...

Introduction: This study evaluated the diagnostic value of the dipyridamole induced electrocardiuogram (ECG) cahnges, comparing with myocardial perfusion imaging. Materials and Methods: 222 patinets were studied with dipyridamole infusion (based on ECG criteria) as well as Dipyridamole-myocardial perfusion imaging (MPI). Results: Abnormal dipyridamole test and abnormal MPI were noted in 1...

doppler-derived myocardial performance index (mpi) , defined as the s um of isovolumetric contraction and relaxation durations divided by ejection time, is an easily measured and reproducible index that shows both systolic and diastolic myocardial function. the goal of this study was to define normal values of right ventricular mpi in neonates in the first 48 to 72 hours of life. fifty-one quie...

Dynamic verification methods are the natural choice for debugging real world programs when model extraction and maintenance are expensive. Message passing programs written using the MPI library fall under this category. Partial order reduction can be very effective for MPI programs because for each process, all its local computational steps, as well as many of its MPI calls, commute with the co...

background: the implications of cardiac risk stratification before orthotopic liver transplantation (olt) are not well established. we studied the usefulness of myocardial perfusion imaging (mpi) in this scenario. methods: mpi data of 24 patients (9 females), candidates of olt, were collected. they underwent mpi as part of their preoperative risk assessment. mpis were interpreted by 2 nuclear p...
