Ultrasound is a key tool for thyroid disease diagnosis but drives overdiagnosis of thyroid cancer. It should be reserved for high-risk patients and incidental nodules, not general screening.
Area of Science:
- Endocrinology
- Diagnostic Imaging
- Oncology
Background:
- Ultrasound is the primary diagnostic method for thyroid diseases.
- High sensitivity of ultrasound contributes to overdiagnosis of thyroid cancer.
- Many thyroid cancers are indolent, meaning treatment may not impact outcomes.
Purpose of the Study:
- To analyze the role of ultrasound in thyroid cancer overdiagnosis.
- To recommend appropriate utilization of diagnostic ultrasound for thyroid nodules.
- To emphasize risk stratification and consensus criteria for maximizing diagnostic ultrasound value.
Main Methods:
- Review of current literature on ultrasound use in thyroid disease.
- Analysis of the impact of ultrasound sensitivity on cancer diagnosis rates.
- Evaluation of overdiagnosis trends in thyroid cancer.
- Assessment of risk stratification and consensus criteria for nodule biopsy.
Main Results:
- Ultrasound significantly contributes to the overdiagnosis of thyroid cancer.
- Many diagnosed thyroid cancers are low-aggressiveness and do not affect patient outcomes.
- Current ultrasound practices can lead to unnecessary diagnosis and treatment.
Conclusions:
- Diagnostic ultrasound should not be used as a general screening tool for thyroid cancer.
- Ultrasound should be reserved for patients at high risk or for evaluating incidental thyroid nodules.
- Implementing prescreening risk stratification and consensus criteria for biopsy maximizes the value of diagnostic ultrasound.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
