Characteristics of ultrasonic imaging of lymph nodes in the necklace in treatment differentiated thyroid cancers patients

Abstract

Background: Ultrasound is a minimally invasive diagnostic technique with the highest accuracy and sensitivity in the diagnosis of lymph node metastasis.

Objectives: The study consists of objectives: Describe the ultrasound imaging characteristics of cervical lymph nodes in treated patients with differentiated thyroid cancer.

Materials and methods: A cross-sectional descriptive study design was conducted on 89 patients diagnosed with differentiated thyroid cancer and found that the cervical lymph nodes were potentially malignant under ultrasonography and indicated fine-needle aspiration cytology under ultrasound guidance.

Results: Among 89 study subjects, the main reason for admission was lymphadenopathy, accounting for 95.5%. The results of papillary pathology accounted for 96.6%. Time after thyroid surgery when cervical lymph node metastasis is detected is 1-3 years (27%). The time after thyroid surgery when cervical lymph node metastasis was detected was 6-36 months (38.2%). Oval shape on ultrasound has 73%, cortex on ultrasound accounts for 65.2%, decreased lymph node on ultrasound accounts for 64%, loss of hilar lymph nodes on ultrasound accounts for 62.9%. Conclusion: Ultrasound plays an important role in diagnosing the stage of the disease, fully and accurately describing the lesions and stage of the disease, helping to increase the effectiveness of treatment.
