概括
原生计算机断层扫描 (CT) 可以帮助早期诊断脊髓炎. 受影响的磁盘显示Hounsfield单位 (HU) 减少了25%,而脊椎显示30%的增加,无论脊椎位置或骨损伤.
科学领域:
- 放射学
- 医学成像
- 脊柱诊断
背景情况:
- 目前的数据限制了本地计算机断层扫描 (CT) 作为脊髓炎的诊断工具的使用,通常保留它们用于骨损伤评估或磁共振成像 (MRI) 的禁用.
- 在早期发现脊髓瘤时,CT扫描的诊断价值,特别是在密度分布模式方面,仍未得到充分研究.
研究的目的:
- 在本地CT扫描中使用Hounsfield单位 (HU) 调查脊椎炎是否会导致受影响的脊椎体和脊椎间盘的密度分布显著,可测量的模式.
- 确定HU测量是否可以作为早期诊断脊髓炎的有价值工具.
主要方法:
- 对136名接受脊髓炎治疗的患者进行了回顾性分析.
- 包括患者的脊椎MRI和CT扫描数据.
- 对受影响的脊椎间盘和脊椎体以及未受影响的相邻水平进行了轴心CT平面测量.
主要成果:
- 与未受影响的邻近磁盘相比,受影响的椎间盘的平均HU显著下降26. 0% (p < 0. 001).
- 与未受影响的邻近脊椎相比,受影响的脊椎体显示HU的平均显著增加为33. 77% (p < 0. 001).
- 这些HU变化在不同脊椎区域 (部,胸部,腰部) 均一致,且不依赖于骨损伤程度.
结论:
- 与相邻结构相比,脊椎间盘HU减少约25%和/或脊椎体HU增加约30%,表明脊椎炎.
- 这些定量CT检测结果可以帮助早期诊断脊髓炎,即使没有明显的骨损伤,无论脊髓受影响的位置如何.

Computed Tomography
6.1K
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...

Radiological Investigation I: X-ray and CT
413
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

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.
