ABSTRACT
Objective:
To explore the diagnostic value of dual-source CT energy parameters in qualitative diagnosis of metastatic cervical lymph nodes after surgical resection of thyroid papillary carcinoma (PTC). Methods Totally 30 postoperative PTC patients with 74 enlarged cervical lymph nodes were enrolled, including 49 metastatic lymph nodes (metastatic group) and 25 non metastasis lymph nodes (non-metastatic group). In addition, 30 cases with benign enlarged cervical lymph nodes were taken as benign group. All subjects underwent dual-source CT scanning. The iodine concentration value of nonenhanced phase (ICNP), arterial phase (ICAP) and venous phase (ICVP), normalized iodine concentration (NIC) and slope of energy spectrum curve (K) were detected and compared among 3 groups.Results:
There were significant differences in ICNP, ICAP, ICVP, NIC and K among 3 groups (all P0.05).Conclusion:
Dual-source CT energy parameters can be used to qualitatively diagnose cervical enlarged lymph nodes after surgical resection of PTC.
