Abstract

Fluids permeating a solid matrix can interact strongly with the pores in which they are contained. Enhanced relaxation behaviour over that of the bulk water can ensue due to the presence of paramagnetic centres or to exchange with bound water at the pore surface. In the latter case, the ratio of pore surface to the pore volume is effective in the relaxation behaviour. NMR provides an effective tool for investigating the solid matrix properties (e.g., pore size distribution) via indirect measurement of the fluid NMR parameters. In addition to spin density, we use T1 mapping to provide an estimate of the specific permeability of sandstone for a few samples.

Calculation of signal intensities in hybrid sequences for fast NMR imaging.

A number of techniques that recently have been used for fast NMR-imaging are based on a hybrid sequence of echo planar imaging (EPI) and FLASH imaging: after each NMR excitation several k-space lines are measured. The complete k-space is covered by performance of several excitations. It has been observed that there is usually an optimal hybrid sequence that maximizes the signal-to-noise ratio. In this work, a method is presented that allows a determination of the optimal sequence as a function of the relaxation times T1 and T2*.

Assessment of valvular heart disease by magnetic resonance imaging.

MRI has developed very rapidly and now provides anatomic and functional information in cases of valvular heart disease. MRI has several important attributes that make it advantageous for the evaluation of valvular heart disease. First, the natural contrast between flowing blood and surrounding cardiovascular structures provides sharp delineation of endocardial and epicardial borders without the need for contrast media. This feature in combination with the essential three-dimensional nature of this imaging technique allows precise quantification of cardiac volumes, function, and mass without the use of any assumed formulas or geometric models. Second, blood flow-sensitive GRE techniques are able to identify areas of turbulent flow caused by stenotic or regurgitant valves. With this technique regurgitant jets can be visualized and semiquantitative grading can be performed as with color Doppler. Third, recently developed velocity-encoded techniques permit measurements of blood flow velocities across stenotic native and prosthetic heart valves and retrograde flow caused by regurgitation. Moreover, the close interstudy reproducibility of measurements of cardiac dimensions and valvular regurgitation suggests a role in assessing the effect of therapeutic interventions.
