Apparent exchange rate for breast cancer characterization
Although diffusion MRI has shown promise for the characterization of breast cancer, it has low specificity to malignant subtypes. Higher specificity might be achieved if the effects of cell morphology and molecular exchange across cell membranes could be disentangled. The quantification of exchange might thus allow the differentiation of different types of breast cancer cells. Based on differen...
متن کاملan appropriate model for exchange rate predictability in iran: comparing potential forecastability
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
Exchange rate pass-through in Iran: Exchange rate effects on the consumer price index
The purpose of this study is to find an accurate estimate of the exchange rate-CPI relationship in Iran over the past three decades. The results of the Granger causality test in the frequency domain demonstrate a strong causation from the exchange rate to CPI especially in the long run. The results of the wavelet analysis show that in the currency crisis periods, the exchange rate-CPI correlati...
متن کاملOptimal experimental design for filter exchange imaging: Apparent exchange rate measurements in the healthy brain and in intracranial tumors
PURPOSE Filter exchange imaging (FEXI) is sensitive to the rate of diffusional water exchange, which depends, eg, on the cell membrane permeability. The aim was to optimize and analyze the ability of FEXI to infer differences in the apparent exchange rate (AXR) in the brain between two populations. METHODS A FEXI protocol was optimized for minimal measurement variance in the AXR. The AXR vari...
متن کاملApparent exchange rate of water in human brain matter revealed by a novel pulse sequence
Introduction Diffusion MRI using pulsed gradient spin echoes (PGSE) is known to yield information about tissue microstructure; for instance, measurements with different diffusion times (TD) provide structural information regarding cellular size distributions [1]. Recent studies have shown that exchange may affect PGSE measurements in white matter [2] and in sub-acute stroke lesions [3]. However...
