- 结核骨损失是肩部不稳定性管理的关键因素.
- 精确的测量对于确定骨重建的必要性至关重要,骨损失的门约为15%.
- 计算机断层扫描 (CT) 是主要的成像模式,但测量技术的验证是有限的.
研究的目的:
- 评估常用的CT技术的准确性,以测量状腺骨损失.
- 评估六种不同的测量方法的数学和统计性能.
主要方法:
- 使用了具有已知的骨损失百分比 (13.8%,17.6%,22.9%) 的解剖学准确模型.
- 六种技术 (相对直径,最适合变体的圆圈,Pico,Sugaya,圆线) 被盲目审查者应用到CT扫描中.

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...

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...
