Summary
Ultrasonography (US) is more sensitive and accurate than computed tomography (CT) for detecting calcifications in thyroid nodules. US is recommended as the preferred imaging method for identifying these calcifications.
Area of Science:
- Radiology
- Medical Imaging
- Endocrinology
Background:
- Calcifications in thyroid nodules can be indicative of malignancy.
- Accurate detection of calcifications is crucial for diagnosis and treatment planning.
Purpose of the Study:
- To compare the diagnostic performance of ultrasonography (US) and computed tomography (CT) in identifying calcifications within thyroid nodules.
- To assess the agreement between US and CT findings with postoperative pathologic diagnoses.
Main Methods:
- Retrospective analysis of 20,248 patient records, focusing on 5247 patients with calcifications identified by US, CT, or pathology.
- Comparison of calcification detection rates between US (n=5247) and CT (n=3827).
- Evaluation of agreement between US and CT findings against a pathologic diagnosis reference.
Main Results:
- Ultrasonography detected calcifications in 92.5% of cases, significantly higher than computed tomography (53.3%).
- The agreement between ultrasonography and pathologic findings (87.9%) was significantly higher than that between computed tomography and pathologic findings (81.9%).
Conclusions:
- Ultrasonography demonstrates superior sensitivity and accuracy compared to computed tomography for detecting thyroid nodule calcifications.
- Ultrasonography is recommended as the primary imaging modality for the detection of calcifications in thyroid nodules.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
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...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
