Prediction method for benign and malignant cervical lymph nodes before minimal thyroid cancer ablation

Abstract

The invention discloses a method for predicting benign and malignant cervical lymph nodes before a minimal thyroid carcinoma ablation operation, which overcomes the defects of lack of specificity, lower diagnosis accuracy and limitation in preoperative judgment of minimal thyroid carcinoma cervical lymph node metastasis by the conventional imaging method at present. The method is characterized by comprising the following steps: S1, acquiring a gray-scale ultrasonic image of a neck lymph node before a thyroid minimal cancer minimally invasive ablation operation; s2, performing ROI outlining and segmentation on a lymph node region in the image; s3, performing image matching and high-throughput feature extraction, and calculating omics features; s4, carrying out feature dimension reduction; s5, establishing a radiomics prediction model, and performing external verification of the model; s6, inputting the ultrasonic image into a radiomics prediction model for prediction and outputting a prediction result. The method for predicting benign and malignant cervical lymph nodes before minimal thyroid cancer ablation can meet clinical diagnosis and treatment requirements, can establish the prediction model for accurate prediction, and can assist in clinical accurate decision making.

Description

technical field [0001] The invention relates to a method for predicting benign and malignant cervical lymph nodes before ablation of thyroid microcarcinoma. Background technique [0002] Imaging-guided ablation of thyroid nodules has the advantages of minimal invasiveness, aesthetics, and safety, and has been widely used in the treatment of benign thyroid nodules, thyroid microcarcinoma, and some metastatic lymph nodes. For thyroid microcarcinoma, ablation therapy is only suitable for small lesions less than 1 cm in the thyroid gland. If cervical lymph node metastasis of thyroid cancer is found before surgery, puncture surgery combined with neck lymph node dissection is still the only option. Therefore, the diagnosis of benign and malignant cervical lymph nodes plays a key role in formulating the treatment plan for patients with thyroid microcarcinoma. [0003] However, the current conventional imaging methods for judging cervical lymph node metastasis of thyroid microcarci...

Problems solved by technology

However, the ultrasonic images of cervical lymph node metastasis in the early stage of partial thyroid microcarcinoma are not typical, and it is difficult to distinguish them from normal hyperplastic lymph nodes in the neck, which brings certain limitations and confusion to clinical diagnosis and treatment, and there is still room for improvement.
