Bilan pré opératoire des cancers du rectum en IRM pelvienne haute résolution avec antenne en réseau phasé

摘要: The main problem associated with rectal cancer treatment is tumor recurrence. Randomized controlled studies have shown that adjuvant preoperative radiation therapy effective for reducing local These also demonstrated there are groups of patients differing degrees risk At one end the spectrum low-risk group: superficial cancer, who can be treated surgery alone. other high-risk a close or involved resection margin at total mesorectal excision, very advanced tumors require longer course chemotherapy and therapy, extensive surgery. Paramount this selection differentiated reliable test used to distinguish these patients. In review article, we will discuss role high-resolution phased array MRI among imaging modalities such as endorectal MRI, US, CT. We illustrate MR results in terms T stage, circumferential margin, locally N stage.
