Fig. 2From: Laparoscopic low anterior resection for rectal cancer wherein the inferior mesenteric artery arose from the superior mesenteric artery: a case reportPreoperative contrast-enhanced computed tomography (CT) and PET–CT. A CT revealed wall thickening in the rectum (arrow). There were no enlarged lymph nodes or distant metastases (a: axial, b: sagittal). Positron emission tomography CT (PET–CT) revealed abnormal accumulation of FDG at the rectal tumor (c). B Three-dimensional-CT angiography reveals the IMA arising from the SMA (a). The IMA is accompanied by the IMV (b). (IMA inferior mesenteric artery, SMA superior mesenteric artery, IMV inferior mesenteric vein, FDG fluorodeoxyglucoseBack to article page
