MRI has been widely accepted as a kind of imaging-aided diagnosis equipment. The MRI guided minimally invasive diagnosis and treatment system integrates MRI technology and minimally invasive treatment technology or even non-invasive treatment based on imaging diagnosis.
While most ablative techniques are currently performed with the help of CT or
ultrasound guidance,a series of disadvantages inherent to both techniques exist.
Although they are fast and relatively cheap, ultrasound guidance might be impeded by tumour inaccessibility, The gases in the lungs and intestines interfere with ultrasound imaging and certain lesions,such as subphrenic lesions, cannot be displayed clearly on US.
CT guidance is irradiating, and the metal artifacts caused by the microwave antenna have an adverse impact on image quality of tumors, and sometimes, axial scans cannot display the full length of the microwave antenna. In addition, the unenhanced CT during ablation cannot clearly demonstrate the boundary of ablated lesions.And both techniques often provide poor tumour and ablation zone visualisation.
Because of the better soft tissue resolution and lack of radiation exposure, MR guidance might be able to overcome the disadvantages of the other techniques.
