Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

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 the...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

科学领域:

  • 法医病理学 法医病理学
  • 放射学 放射学是一门学科.
  • 死亡后的影像成像研究

背景情况:

  • 死后计算机断层扫描 (PMCT) 有助于确定死亡原因.
  • 了解自然死后的变化,如肺低位症,对于准确的PMCT解释至关重要.
  • 死后肺部发现的时间演变需要详细的调查.

研究的目的:

  • 为了研究死后胸部CT检测结果在小猪的自然时间变化.
  • 为了将这些CT发现与肺部的病理变化相关联.
  • 建立解释死后成像中的肺部异常的基线.

主要方法:

  • 连续的胸部PMCT扫描在24小时内每小时对4只小猪进行一次.
  • 在最后的CT扫描后立即进行了肺组织的解剖和病理检查.
  • 在死亡后立即从两个额外的猪仔中准备了病理参考标本.

主要成果:

  • 地玻璃衰减 (GGA) 在死后几个小时的肺部出现,并随着时间的推移逐渐增加.
  • 组织学检查证实,GGA与肺相对应.
  • 增加的CT衰减在肺的背部区域更为明显;巩固和肺部溢出不存在.

结论:

  • 肺部的地面玻璃衰减是一种自然的死后过程,表明肺.
  • 将时间依赖的GGA与病理发现区分开来,对于使用PMCT.CT准确确定死亡原因至关重要.
  • 这项研究为死后CT检查中观察到的肺部变化提供了时间参考.
