概括

这项研究建立了儿童关节形态的正常计算机断层扫描 (CT) 测量,揭示了根据年龄和性别的变化. 这些发现有助于识别关节形和规划儿童手术干预.

科学领域:

儿科放射学儿科放射学
整形外科成像整形外科成像
发育的解剖学发育的解剖学

背景情况:

关节形态表现出由年龄和性别影响的显著变化.
计算机断层扫描 (CT) 对于评估骨形态至关重要.
由于缺乏对健康儿童的规范性CT数据,因此需要进行这项研究.

研究的目的:

通过对健康儿童的CT测量来定义骨形态的正常范围.
根据性别和特定年龄组分析这些测量结果.
为儿童部形早期检测和手术规划提供参考数据.

主要方法:

对1-18岁儿童的盆腔CT扫描进行了回顾性分析 (n=110).
测量包括侧向中心边角 (LCEA),形角,前部中心边角 (ACEA),形版 (AcetV),前部形板块角 (AASA) 和后部形板块角 (PASA).
数据按性别和年龄组 (2-7,8-11,12-18岁) 分层.

主要成果:

乙体版本 (AcetV),AASA,PASA,LCEA和ACEA随着年龄的增长显著增加 (P < 0.001).
骨角随着年龄的增长而减少 (P < 0.001).
与男性相比,女性表现出更高的AcetV和PASA (P < 0.001).

结论:

儿童关节发育的特点是年龄和性别依赖的形态变化.
已建立的规范性CT测量作为评估儿科关节发育的宝贵工具.
这些数据支持早期识别关节形,并为骨科手术策略提供信息.

Imaging Studies III: Computed Tomography

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...

Computed Tomography

Computed 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...
