Diagnostic and therapeutic processes utilizing magnetic resonance imaging techniques

摘要

Method for diagnosing and treating tissue suspected of containing a lesion. A shaped pulse sequence is selected for each of waveform, phase and frequency components of an RF signal based upon characteristics of the tissue suspected of containing a lesion and an RF signal comprised of the selected waveform, amplitude and frequency shaped pulse sequences generated. A series of echoes is received in response to the generated RF signal and a real-time MR image of the tissue suspected of containing a lesion is produced using the series of received echoes. The tissue is then diagnostically evaluated for the presence of lesions using the produced real-time MR image. Using the produced real-time MR image of the tissue, boundaries between the tissue and each lesion detected during the evaluation of the tissue are determined and the lesion removed from the surrounding healthy tissue using a therapeutic delivery system while observing the boundary between the lesion and the surrounding healthy tissue using the produced real-time MR image.
