- 整形外科手术 整形外科手术
- 医疗成像医学成像
- 生物医学工程 生物医学工程
背景情况:
- 三维 (3D) 打印模型有助于手术规划,允许模拟手术并精确确定植入物尺寸和位置.
- 患者专用仪器 (PSI) 利用先进的成像技术,为骨科的量身定制的外科手术方法提供动力.
研究的目的:
- 评估和比较计算机断层扫描 (CT) 和磁共振成像 (MRI) 的准确性,用于使用PSI进行全膝关节整形术 (TKA) 的手术前规划.
主要方法:
- 从2019年到2022年使用患者特定仪器 (PSI) 对全膝关节关节置换术 (TKAs) 的前性分析.
- 计划与实际骨切除厚度的比较,CT结合估计的软骨厚度和MRI直接可视化软骨.
主要成果:
- 在基于CT和基于MRI的PSI组之间,对于距离股骨和侧切除术的平均计划与实际骨切割厚度没有发现显著差异.
- 计划的远切口厚度为8.5 ± 0.8毫米 (CT) 与8.9 ± 0.5毫米 (MRI),实际厚度为9.8 ± 0.54毫米 (CT) 与8.3 ± 1.1毫米 (MRI).
- 计划的侧切口厚度为2.6 ± 1.1毫米 (CT) 与2.43 ± 1.66毫米 (MRI),实际厚度为2.5 ± 0.6毫米 (CT) 与2.88 ± 1.12毫米 (MRI).
结论:
- 虽然MRI可视化软骨,但基于MRI的PSI系统无法比基于CT的PSI系统更准确地预测TKA中的骨切口厚度.
- CT和MRI都是可行的成像方式,用于在使用PSI的骨科手术中进行术前规划,对骨切除尺寸的预测准确度相似.

Imaging Studies for Cardiovascular System III: X-Ray
193
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

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.

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...
