Summary
Thyroid cartilage ossification shows variability, limiting its accuracy for individual age estimation. Advanced CT imaging confirmed that while age correlates with morphological changes, it is not precise enough for forensic or clinical use.
Area of Science:
- Forensic Anthropology
- Radiology
- Anatomy
Background:
- Thyroid cartilage ossification is studied for age estimation.
- Previous studies show varied results regarding its accuracy.
- Advances in imaging may offer more precise evaluation.
Purpose of the Study:
- To evaluate the precision of thyroid cartilage ossification assessment using advanced CT imaging for age estimation.
- To analyze the ossified volume of the thyroid cartilage in a large patient cohort.
Main Methods:
- Retrospective analysis of CT scans from 312 French patients.
- Utilized postprocessing software for 3D reconstructions.
- Calculated the ossified volume of the thyroid cartilage.
Main Results:
- Pearson's correlation coefficients for ossified volume were 0.73 (men) and 0.75 (women).
- Significant inter-individual variability in ossification was observed.
- A correlation between civil age and morphological changes was found, but with limitations.
Conclusions:
- Thyroid cartilage ossification assessment using advanced CT imaging demonstrates considerable inter-individual variability.
- Current methods based on thyroid cartilage ossification are not sufficiently accurate for individual age assessment.
- Further research may be needed to refine age estimation techniques.

01:10Computed Tomography
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...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:09Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:27Growth of Cartilage and Bone Tissue
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...
01:25Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
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...
01:23The Thyroid Gland
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...
