Application of PET-CT in Medical Diagnosis of Thyroid Tumor

Abstract

Thyroid tumors are divided into benign and malignant tumors, which are usually found in physical examination without any clinical manifestations in the early stage. When the tumor increases, it can compress the trachea, esophagus, recurrent laryngeal nerve, etc. The correct diagnosis rate of thyroid tumor probably determines the future cure of patients. The purpose of this article is to study the application of PET-CT in the medical diagnosis of thyroid tumors. Thyroid tumors and PET-CT were briefly introduced through literature research and investigation, and the specific application of PET-CT and common diseases causing thyroid nodules were analyzed. Specific applications of PET-CT include epilepsy localization, brain tumor characterization and recurrence judgment, early diagnosis of dementia, brain receptor research, cerebrovascular diseases, drug research, advanced health examination, lung cancer examination, etc. The effects of PET-CT and CT in the medical diagnosis of thyroid tumors were compared through comparative experiments. The results showed that for benign thyroid tumors, the diagnostic accuracy of PET-CT was 14% higher than that of CT. For malignant thyroid tumors, the diagnostic accuracy of PET-CT is 15% higher than that of CT. In addition, PET-CT diagnosis can reduce the probability of thyroid nodules being misdiagnosed as thyroid tumors.
