Application Of High Resolution Magnetic Resonance Imaging In Locally Advanced Rectal Cancer

With the development of imaging techniques,high resolution magnetic resonance imaging(HRMRI)with its high soft tissue resolution and high spatial resolution characteristics is gradually valued by people.High resolution magnetic resonance imaging(HRMRI)has become an indispensable tool for multidisciplinary teams addressing locally advanced rectal cancer.Preoperative HRMRI is accurate in predicting tumor stage and poor prognostic features,such as circumferential resection margin and extramural venous invasion,et al.HRMRI is a precise diagnostic tool to select who may benefit from neo-adjuvant therapy and to avoid over treatment in those patients who can proceed directly to surgery,thus achieving better prognosis and quality of life for patients with locally advanced rectal cancer.HRMRI can also preliminary assessment the effect of neoadjuvant therapy,and provide an indicative reference for further line of preoperative treatment.
