Goiter is a common condition that requires the help of imaging tests. At present, the imaging examination grading system for goiter mainly includes the TI-RADS grading system of the American College of Radiology and the CRITERIA grading system of the Royal College of Physicians of the United Kingdom. These grading systems are designed to provide physicians with a standardized diagnostic approach to help them better assess the nature and risk of a goiter.
1. The TI-RADS grading system of the American College of Radiology.
The TI-RADS grading system is an ultrasound image-based classification system for goiter that aims to provide physicians with a standardized way to assess the likelihood of malignancy of a thyroid mass and to monitor its changes. This system classifies goiter into the following 6 grades:
1.Ti-RADS Level 0: No anomalous findings.
2.Ti-RADS grade 1: normal thyroid gland with no mass.
3.Ti-RADS grade 2: benign mass, including cystic thyroid changes, intrathyroid hemorrhage, inflammatory lesions, etc.
4.Ti-Rads grade 3: potentially benign non-malignant masses, such as nodular goiter, thyroid cysts, etc.
5.Ti-Rads grade 4: suspicious malignant mass with some suspicion of malignancy.
6.Ti-RADS grade 5: highly suspicious of malignancy, almost certain malignancy.
2. The Criteria grading system of the Royal College of Physicians of the United Kingdom.
The CRITERIA grading system is a classification system for goiter based on CT and MRI images, which aims to provide physicians with a standardized method for assessing benign and malignant goiter masses. The system classifies the thyroid mass into the following 4 grades:
1.Criteria A: No anomalous findings.
2.Criteria B: Benign mass, including cystic thyroid changes, intrathyroid hemorrhage, etc.
3.Criteria C: Potentially benign, non-malignant mass, such as nodular goiter.
4.Criteria D: malignant mass, with some suspicion of malignancy.
3. The Chinese version of the thyroid imaging examination grading system.
The Chinese version of the goiter imaging examination grading system is established on the basis of reference to relevant literature and clinical practice experience at home and abroad, aiming to provide Chinese doctors with a more suitable method for the imaging examination and grading of goiter for Chinese people. The system classifies goiter into the following 5 grades:
1.tr0: no anomalous findings.
2.TR1: normal thyroid gland without mass.
3.TR2: Benign mass, including cystic changes of the thyroid gland, intrathyroid hemorrhage, etc.
4.TR3: Potentially benign non-malignant mass, such as nodular goiter.
5.TR4: Malignant mass, including suspicious malignant and highly suspicious malignant mass.
Fourth, summary and outlook.
The imaging grading system for thyroid masses is an important tool to assess its nature and risk, helping doctors to better diagnose and **. At present, there are a number of grading systems at home and abroad, but there are certain differences between the systems, which need to be further improved and unified. In the future, with the continuous development of medical technology, it is believed that there will be more accurate and convenient imaging methods to assess the nature and risk of goiter.
