In magnetic resonance imaging, balanced steady-state free precession acquisition using the elliptical signal model geometrical solution can be combined with a GRAPPA parallel imaging reconstruction that preserves phase information to shorten scan times.

This study introduces a methodology for detecting subtle variations in tissues with very rapid T2* decay through a difference image ultra-short T2* mapping technique using a 3D cones k-space trajectory. The new method is demonstrated in both a normal and surgically repaired Achilles tendon. The resulting UTE images are differenced and T2* values were calculated using a mono-exponential least squares fit on a voxel by voxel basis. The ultrashort T2* maps yield very consistent short T2* values in healthy tendon of 0.3-0.5 ms, while notable variations and elevations of T2* values are observed in surgically repaired tendon.

The purpose of this project is to build a model, which mimics physiological conditions of the human cardiovascular system in order to simulate the parameters of the human heart in vivo. For this project, it was developed a flow phantom with vessel mimicking material, as well as blood-mimicking and tissue-mimicking fluid. Phantoms in general are specifically designed objects involving dedicated biomaterials to simulate special realistic circuits of human beings. To develop the flow phantom, low-priced biomaterials for blood mimicking fluid, tissue mimicking, and vessel mimicking material was researched.
