Evaluation of Ultrasonography and Computed Tomography in Preoperative of Cervical lymph Node Metastases in Papillary Thy-roid Carcinoma
YANG Feng
Abstract：Objective To evaluate the impact of preoperative ultrasonography ( US) and computed tomography ( CT) on the preopera-tive of cervical lymph node metastases in papillary thyroid carcinoma ( PTC).Methods Medical records and imaging findings were retro-spectively analyzed for 252 patients with PTC who underwent thyroidectomy with neck dissection between January , 2008 and December , 2013.Results The sensitivity of both imaging techniques was lower in the central neck ( 23%, 41%) than in the lateral neck ( 70%, 82%).The specificities of US and CT were 97%and 90%in the central neck , and 84%and 64%in the lateral neck.The surgical plans for therapeutic neck dissection were based on imaging findings in 59% patients who underwent lateral compartment neck dissection and in 32.1%patients who underwent central compartment neck dissection.Conclusion The roles of preoperative US and CT in surgical planning for central compartment neck dissection in PTC are limited because of their low sensitivity in the central neck , but US and CT may be useful in cases with non-palpable lateral neck nodes.
