概括
肺动脉直径和PA/AO比率可能表明急性肺栓塞 (APE). 然而,总缺陷和右视觉缺陷得分,以及主要肺动脉扩张,更能预测慢性肺血栓栓塞性疾病 (CPTED).
科学领域:
- 放射学和核医学 放射学和核医学
- 心血管成像 - 心血管成像
- 肺部医学 肺部医学
背景情况:
- 急性肺栓塞 (APE) 是一种需要准确诊断的危急疾病.
- 识别患有慢性肺血栓栓塞性疾病 (CPTED) 风险的患者对于长期管理至关重要.
- 肺 perfusion SPECT-CT提供了肺血管和 perfusion 的详细成像.
研究的目的:
- 评估从肺 perfusion SPECT-CT 中的肺动脉直径和半定量视觉评分 (SVS) 是否可以预测APE患者的CPTED.
- 在APE中确定主要肺动脉 (MPA) 直径和MPA/大动脉 (PA/AO) 比率的诊断值.
- 评估输液缺陷得分 (总缺陷 - TD,右视缺陷 - RVD) 的预测能力,用于CPTED开发.
主要方法:
- 一项观察性研究包括142名接受SPECT-CT肺 perfusion的患者,分为APE (+) (n=42) 和APE (-) (n=100) 组.
- 使用CT图像测量MPA,RPA,LPA直径和PA/AO比率.
- 对于APE (+) 组的输液缺陷进行了SVS;17名CPTED患者与已康复的APE患者进行了比较.
主要成果:
- 在APE (+) 和APE (-) 组 (p<0.001) 之间观察到MPA,RPA,LPA直径和PA/AO比率的显著差异.
- 与已康复的APE患者 (p<0.05) 相比,CPTED组的MPA直径 (31.67±15.65毫米),TD (29.88±15.59),RVD (17.65±10.51) 和PA/AO比率 (0.91±0.18) 显著更大,相比之下,CPTED组的MPA直径 (31.67±15.65毫米),TD (29.88±15.59),RVD (17.65±10.51) 和PA/AO比率 (0.91±0.18) 显著更大.
- MPA扩张和高的PA/AO比率与APE有关,而TD和RVD得分表明CPTED风险.
结论:
- 肺动脉直径和PA/AO比率是APE诊断的有用指标.
- 结合MPA扩张和PA/AO比率,TD和RVD得分是识别APE病史患者中CPTED的有价值的预测指标.
- 肺 perfusion SPECT-CT 参数可以帮助分层对急性肺栓塞后慢性并发症的风险.

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

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...

Pulmonary Embolism I: Introduction
7
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

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...
