3D TrueFISP imaging of mouse brain at 4.7T and 9.4T.

Purpose: To examine the ability of TrueFISP imaging for evaluating tumor size in mouse brain at high field.

Materials And Methods: Brains of healthy and glioma-implanted nude mice were imaged at 4.7T and 9.

Application of MRI phase-difference mapping to assessment of vascular concentrations of BMS agent in mice.

Direct quantitation of contrast agent concentration can be performed using dynamic susceptibility contrast MRI. This method is based on phase imaging and administration of paramagnetic agents such as gadolinium-chelates. This technique has only been applied on humans or primates.

Blood velocity assessment using 3D bright-blood time-resolved magnetic resonance angiography.

Blood velocity is a functional parameter that is not easily assessed noninvasively, especially in small animals. A new noninvasive method that uses magnetic resonance angiography (MRA) to measure blood flows is proposed. This method is based on the time-of-flight (TOF) phenomenon.
