摘要
ERUS and MRI should be seen more as complementary rather than competitive techniques Each has its own strengths and weaknesses ERUS is better in showing the tumor extent in small superficial tumors, whereas MRI is superior in imaging the more advanced tumors The choice of imaging technique depends also on the amount of information that is required for choosing certain treatment strategies, like the distance to the mesorectal fascia for a short course of preoperative radiotherapy For lymph node imaging, both techniques are at present only moderately accurate, although this could change with advances in new MR techniques
