What is the best method for detecting thyroid lesions?

High-resolution ultrasound is considered the best method for detecting thyroid lesions due to its ability to provide detailed images of the thyroid gland structure and any abnormalities that may be present. Ultrasound is particularly effective for evaluating the characteristics of thyroid nodules, such as their size, composition (solid or cystic), and vascularity. It's a non-invasive procedure that does not involve radiation exposure, making it a safe choice for many patients, including pregnant individuals.

Additionally, ultrasound can also guide fine needle aspiration biopsy if there are nodules that warrant further examination, promoting a more accurate diagnosis.

While computed tomography (CT) and magnetic resonance imaging (MRI) can provide valuable information in certain contexts, they are not first-line imaging modalities for thyroid lesions. CT is better suited for evaluating cervical structures in more complex cases, and MRI is typically used for soft tissue assessment but is less practical for routine thyroid evaluations due to its cost and availability. X-ray is generally not useful in assessing thyroid lesions as it lacks the resolution and specificity for soft tissue that ultrasound provides.
