Core Tip

Core tip: The preoperative nodal diagnostic ability of multi-detector spiral computed tomography for advanced gastric cancer was examined more precisely using data from patients for whom precise one-to-one correspondence of lymph nodes could be performed between computed tomography and intranodal pathological metastatic patterns by using lymph node mapping. The number of dissected, metastatic, and detected nodes on computed tomography were 4241, 801, and 897, respectively. The sensitivity of multi-detector spiral computed tomography for nodal diagnosis was as good as 91% with the critical value of 7.6 mm for the long axis. The large nodular or diffuse metastases were easy to diagnose. However, the specificity was as low as 47%, because most of the metastatic nodes in gastric cancer were small nodes.
