Abstract: A system and method of evaluating the effectiveness of antiangionetic therapy is described. A patient or test animal is treated with an antiangionetic substance. Magnetic resonance imaging data is obtained prior to and subsequent to the treatment. The parameters of the imaging process are configured so that, by administering a intravascular contrast agent, the relative size of the microvascular and the total vascular volumes in a region of interest may be obtained, so as to form a vascular size index. The value of the vascular size index and other pharmacokinetic data obtained by the administration of a diffusible contrast agent are used to assess the efficacy of the treatment or the antiangionetic substance being studied.

Abstract: A device has a resonator coupled to input and output nodes, the resonator being characterized by a transducer to drive the output node, and further characterized by a feedthrough capacitance such that portions of the input signal bypass the transducer to allow a spurious signal to reach the output node. The device includes a compensation capacitor coupled to the output node to define a compensation capacitance in accordance with the feedthrough capacitance. A phase inversion circuit is coupled to the compensation capacitance to generate a compensation signal and coupled to the output node such that the spurious signal is offset by the compensation signal. In some cases, a differential amplifier of the phase inversion circuit has the compensation capacitance in a feedback path to offset the feedthrough capacitance. In these and other cases, the compensation capacitance and the feedthrough capacitance may be unmatched to avoid overcompensation.
