چکیده
Figure 3: Simulated metabolism using an outer region with ρP=0.027, kP-L=0.018, kL-P=0.125, P∞=1.733, and an inner region with ρP=0.027, kP-L=0.088, kL-P=0.17, P∞=2.5. The default sampling is 30 samples between t=0 and 29 s and a flip angle of 10°. The optimal sampling over the range given above suggests samples at 0, 2.9, 13.1, 41.9 s and flip angles of 23.2, 36.6, 47.3, and 90°. Note the decreased error in the sum of squared differences, especially for the noisier k parameters. ( ) ( )

Analytical determination of the chemical exchange saturation transfer (CEST) contrast in molecular magnetic resonance imaging
Magnetic resonance based on molecular imaging allows tracing contrast agents thereby facilitating early diagnosis of diseases in a non-invasive fashion that enhances the soft tissue with high spatial resolution. Recently, the exchange of protons between the contrast agent and water, known as the chemical exchange saturation transfer (CEST) effect, has been measured by applying a suitable pulse ...

Extended Abstract. Inferences for spatial data are affected substantially by the spatial configuration of the network of sites where measurements are taken. Consider the following standard data-model framework for spatial data. Suppose a continuous, spatially-varying quantity, Z, is to be observed at a predetermined number, n, of points ....[ To Countinue Click here]

Introduction: We have developed hyperpolarized 1,4-C2 fumarate as a new promising metabolic marker for oncology. Metabolic parameters like up-take and conversion significantly influences imaging parameters like timing and concentration. Here we show a comparison between two substrates, hyperpolarized 1-C pyruvate, which previously has been shown to be an oncology marker and the new agent, 1,4-C...

Acceptance sampling (AS), as one of the main fields of statistical quality control (SQC),involves a system of principles and methods to make decisions about accepting or rejecting alot or sample. For attributes, the design of a single AS plan generally requires determination ofsample size, and acceptance number. Numerous approaches have been developed foroptimally selection of design parameters...
متن کاملOptimal strategy for b-values selection for lung morphometry with hyperpolarized 3He diffusion MRI
Introduction: The lung morphometry technique [1] allows the evaluation of lung microstructure based on an MRI measurement of hyperpolarized He gas diffusion. In this approach, acinar lung airways are considered as cylinders covered by alveolar sleeves [2]. Diffusion of He gas in each airway is anisotropic and described by distinct longitudinal and transverse diffusion coefficients, DL and DT. A...
