CT is the established imaging technique for evaluation of pancreatic adenocarcinoma. MRI, however, can play a major role in this disease. The objective of this study is to illustrate the strengths of MRI for evaluating pancreatic adenocarcinoma.
The superior soft-tissue contrast of MRI compared with CT is useful in the detection and characterization of non-contour-deforming pancreatic masses. MRI compared with CT may be more sensitive in the detection of distant disease, better for defining appropriate surgical candidates, and better for characterizing small liver metastases and peritoneal and omental metastases.
CT是评估胰腺腺癌的既定成像技术。然而,MRI在这种疾病中也能发挥重要作用。本研究的目的是阐述MRI在评估胰腺腺癌方面的优势。
与CT相比,MRI具有更好的软组织对比度,有助于检测和鉴别未使胰腺轮廓变形的肿块。与CT相比,MRI在检测远处病变方面可能更敏感,更有利于确定合适的手术候选者,也更有利于鉴别小的肝转移灶以及腹膜和网膜转移灶。
