概括
计算机断层扫描 (CT) 扫描的水平显著影响了对回骨槽形态的评估. 大多数患者在不同扫描级别呈现出不同的槽形状,这凸显了扫描级别选择在脚和脚成像中的重要性.
科学领域:
- 整形外科手术 整形外科手术
- 放射学 放射学是一门学科.
- 人体解剖学 解剖学 解剖学
背景情况:
- 之前的研究评估 retromalleolar 沟形态使用轴性磁共振成像在10毫米以上的侧面骨尖端.
- 缺乏证据支持这种特定水平进行准确的形态评估.
研究的目的:
- 为了确定轴向计算机断层扫描 (CT) 扫描的水平如何影响对后脑沟形态的评估.
主要方法:
- 一项涉及122名患者的横截面研究,这些患者接受了足部或脚病理的CT扫描.
- 在三个轴心CT水平 (8,10和12毫米以上的侧面骨尖端) 评估了后脑状槽形状.
- 槽形状和长度由两个独立的骨科外科医生评估.
主要成果:

4.5K
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...

01:10Bones of the Lower Limb: Tibia and Fibula
3.2K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
