This study reviews pulmonary embolism (PE) signs on CT angiography and conventional angiography. CT angiography is recommended as a less invasive primary diagnostic tool for thromboembolic disease.
Area of Science:
- Radiology
- Cardiovascular Imaging
- Pulmonary Medicine
Background:
- Pulmonary embolism (PE) is a significant cause of morbidity and mortality.
- Accurate diagnosis relies on identifying characteristic imaging findings.
- Both CT angiography and conventional angiography have been used to diagnose PE.
Purpose of the Study:
- To review classic direct and indirect angiographic signs of acute and chronic PE.
- To correlate these angiographic findings with MDCT (multi-detector computed tomography) findings.
- To compare the diagnostic utility of CT angiography and conventional angiography for PE.
Main Methods:
- Review of direct and indirect angiographic signs of PE.
- Correlation of angiographic findings with MDCT.
- Comparative analysis of CT angiography and conventional angiography in PE diagnosis.
Main Results:
- MDCT demonstrates specific signs correlating with angiographic findings in PE.
- CT angiography and conventional angiography show complementary roles in PE diagnosis.
- CT angiography is identified as a primary diagnostic modality.
Conclusions:
- CT angiography and conventional angiography play complementary roles in diagnosing acute and chronic thromboembolic disease.
- Conventional angiography serves as a problem-solving tool post-CT angiography.
- CT angiography is preferred due to its less invasive nature compared to conventional angiography.

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...
