THYROID, PAPILLARY THYROID CANCER
Papillary thyroid microcarcinoma (PTMC) is a form of papillary thyroid cancer (PTC) with a maximum diameter of 1 cmAs an ultrasound-guided interventional technique, RFA is a less invasive alternative to surgeryUltrasound images of PTMC locoregional lymph nodes status in different treatment stages. (The 2017 RFA guideline of the Korean Society of Thyroid Radiology acknowledged RFA as a therapeutic option for patients with primary thyroid cancer who refuse surgery or who are unable to undergo surgeryDespite the widespread acceptance of RFA among physicians and patients, the standardization of the procedure remains relatively empirical. There exist variations in the energy and time parameters employed for ablating PTMC, underscoring the need for quantification and improved precisionMany postoperative follow-up patients are deeply concerned about the complete absorption time of the RFA zone. To provide more accurate answers to patients, we reviewed our previous clinical work and research findings
