Summary
Chest X-rays are crucial for diagnosing pulmonary embolism (PE) by revealing signs of PE or other conditions. Careful interpretation of radiologic findings aids in accurate diagnosis and selecting further tests.
Area of Science:
- Radiology
- Pulmonary Medicine
- Diagnostic Imaging
Background:
- Chest radiography is a primary imaging modality for patients with suspected pulmonary embolism (PE).
- It can visualize radiologic signs of PE, with or without pulmonary infarction.
- It also helps detect alternative diagnoses that mimic PE.
Purpose of the Study:
- To highlight the diagnostic role of chest radiography in suspected pulmonary embolism.
- To emphasize the importance of interpreting various radiologic signs for accurate diagnosis.
- To guide the selection of further diagnostic investigations.
Main Methods:
- Review of radiologic signs visualized on chest radiographs in patients with suspected PE.
- Analysis of signs related to vascularization, parenchyma, pleura, and diaphragms.
- Distinguishing between pulmonary embolism with and without infarct based on imaging findings.
Main Results:
- Chest radiography reveals numerous signs indicative of PE, including those related to vascular changes and parenchymal abnormalities.
- Specific signs can differentiate between pulmonary embolism with infarct and without infarct.
- The presence of other diseases mimicking PE can be identified.
Conclusions:
- Chest radiography plays a significant role in the diagnostic workup of suspected pulmonary embolism.
- A global and careful interpretation of radiologic signs is essential for its diagnostic value.
- It serves as a valid support for the overall diagnostic approach, guiding the selection of additional tests.
