Table 2 Advantages and disadvantages of imaging modalities in preoperative staging
Imaging modalities | Advantages | Disadvantages |
Preoperative staging | ||
EUS | Depth of tumor invasion in early rectal cancer | Limited field of view Perirectal invasion and LN metastasis |
CT | Wide availability Fast scanning time | Local staging and CRM involvement in lower rectal cancer |
MRI | High soft tissue resolution Local staging and CRM involvement | Distant metastasis |
PET/CT | Distant metastasis | Poor spatial resolution Perirectal invasion and CRM involvement |
Post-therapeutic restaging | ||
EUS | None | Low accuracy of T staging and LN staging |
CT | Relatively high accuracy of CRM status | Relatively low accuracy of T staging and LN staging |
MRI | High specificity of therapeutic response assessment High accuracy of CRM involvement | Relatively poor sensitivity |
PET/CT | Distant metastasis | No standard parameter and follow-up protocol |
