From Philips Medical Systems;
The clinical capabilities of MR will further expand. Inside and out, the Achieva is a friendly, open system designed for optimal patient comfort and maximized work flow with high functionality.
The Achieva 1.5T can be upgraded to Achieva I/T, with three configurations optimized for MR guided interventions and therapy:
•
Achieva I/T Neurosurgery
•
Achieva I/T Cardiovascular (or XMR - combining an Achieva 1.5T CV system and an X-Ray system)

Spin dephasing for complex flow patterns like turbulence. This effect must be taken into account when evaluating the extent of vascular stenosis. The degree of the signal loss depends on the flow model and pulse sequence used. | | | | | |

This effect is an additional electrical charge generated by ions in blood (loaded particles) moving perpendicular to the magnetic field.
At 1.5 T, no significant changes are expected; at 6.0 T a 10% blood pressure change is expected.
A blood pressure increase is predicted theoretically for a field of 10 T. This is claimed to be caused by interaction of induced electrical potentials and currents within a solution, e.g. blood, and an electrical volume force causing a retardation in the direction opposite to the fluid flow. This decrease in blood flow-velocity must be compensated for by an elevation in pressure.
Static magnetic field gradients of 0.01 T/cm (100 G/cm) make no significant difference in the membrane transport processes. The influence of a static magnetic field upon erythrocytes is not sufficient to provoke sedimentation, as long as there is a normal blood circulation.
The magnetohydrodynamic effect which results from a voltage occurring across a vessel in a magnetic field, is irrelevant at the field strengths used. | | | |
