| 摘要 |
Described herein is a medical imaging technique that includes directing ultrasound waves into a portion of a body of interest during at least a portion of a time period during which an MR imaging process is simultaneously performed on the portion of the body of interest such that the MR signal is altered by the application of the ultrasound waves. The ultrasound waves may be applied continually during the MR imaging process, or only during a portion thereof. The frequency of the ultrasound waves may be substantially the same as, or different than that of the MR signals. Images may be produced from only the MR imaging process or both the MR imaging process and the application of ultrasound waves prior to the imaging sessions.
