まとめ
コンピュータートモグラフィーによる死後の肺生検は,肺炎の診断に適しています. この方法は,死後のCTスキャンと血液検査で炎症の発見がない場合に肺炎を特定します.
科学分野:
- 法医病理学
- 放射線科
- 医療診断
背景:
- 死後の肺炎の診断は困難です
- 死後のCT (PMCT) や血液マーカーのような伝統的な方法は,常に肺炎を正確に検出することはできません.
- ヒストパトロジーは 黄金基準のままですが 侵襲的です
研究 の 目的:
- 肺炎を診断するために,コンピュータトモグラフィー (CT) による死後の肺生検の可行性を評価する.
- PMCTと血液分析から得られた診断結果とヒト病理学的結果を比較する.
主な方法:
- 死亡から3日以内にヒト組織病理学的に確認された中性粒子の浸透を患った13人の患者を含む.
- すべての患者はPMCTを受け,その後CTによる死後の肺バイオプシーが行われました.
- 死後の血液サンプルでは,C反応性タンパク質 (CRP) とプレセプシン (P-SEP) を分析した.
主要な成果:
- PMCTは38. 5%の症例で肺低位症を示し,他の症例では様々な異常 (網状,グラス状,斑点状,結節状) を示した.
- すべての測定可能なCRP値は正常範囲を超えたが,P-SEP値は16. 7%の症例で正常であった.
- PMCTと血液マーカーが決定的でない場合でも,CTによる生検は肺炎を成功裏に検出しました.
結論:
- PMCTと血液検査だけで死後の肺炎を診断することは 限界があります
- CTによる死後の肺生検は,他の方法が失敗したときに肺炎を特定するための貴重なツールです.
- この技術により 診断の精度が向上します

01:13Radiological Investigation III: Pulmonary Angiogram and PET Scan
167
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...

204
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

221
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

6.2K
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...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
