Spectroscopic imaging: basic principles.

Spectroscopic imaging (SI) is a method that enables the measurement of the spatial distribution of metabolite concentrations in tissue. In this paper, an overview of measurement and processing techniques for SI is given. First, the basic structure of SI pulse sequences is introduced and the concepts of k-space, point spread function and spatial resolution are described. Then, special techniques...

Imaging of flow: basic principles

Indicator dilution techniques for measuring blood flow have existed for more than 100 years. Indicators may be either intravascular, or freely diffusible. Early techniques establishing the mathematical framework for flow (the Fick principle, Kety–Schmidt method, and central volume principle) were mainly based on arterial and venous blood sampling. Tissue perfusion measured by MR techniques may ...

MR spectroscopic imaging: principles and recent advances.

MR spectroscopic imaging (MRSI) has become a valuable tool for quantifying metabolic abnormalities in human brain, prostate, breast and other organs. It is used in routine clinical imaging, particularly for cancer assessment, and in clinical research applications. This article describes basic principles of commonly used MRSI data acquisition and analysis methods and their impact on clinical app...
