How to look at chest CT
Chest CT (computed tomography) is a common medical imaging examination method and is widely used in the diagnosis of lung diseases, heart diseases and thoracic structures. With the popularization of medical technology, more and more people are paying attention to how to interpret chest CT reports. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce you to the interpretation method of chest CT in detail and provide structured data for reference.
1. Basic principles of chest CT
Chest CT uses X-ray beams to scan the human chest from multiple angles, and then uses a computer to reconstruct cross-sectional images. Its resolution is much higher than that of ordinary X-ray films, and it can clearly show subtle changes in the lungs, heart, mediastinum and other structures.
2. Common applications of chest CT
| Application areas | Specific use |
|---|---|
| lung disease | Diagnosis of pneumonia, tuberculosis, lung cancer, emphysema, etc. |
| heart disease | Assessment of coronary heart disease, cardiomyopathy, pericardial effusion, etc. |
| Thoracic Structure | Examination of rib fractures, pleural lesions, mediastinal tumors, etc. |
3. Interpretation method of chest CT report
1.Observe lung structure: Normal lung CT shows a uniform black-gray color. If white shadows (such as ground-glass shadows, consolidation shadows, etc.) appear, it may indicate inflammation, edema or tumors.
2.Analyze heart morphology: Heart size, whether there is pericardial effusion, whether coronary arteries are calcified, etc. are important indicators.
3.Examine the mediastinum and lymph nodes: Mediastinal widening or lymph node enlargement may indicate infection, tumor, or immune disease.
4.Pay attention to the pleura and chest wall: Pleural thickening, effusion, or chest wall mass require further evaluation.
| CT performance | possible disease |
|---|---|
| ground glass shadow | Early pneumonia, pulmonary edema, interstitial lung disease |
| Consolidation shadow | Bacterial pneumonia, lung cancer |
| nodular shadow | Tuberculoma, lung cancer, granuloma |
| hollow shadow | Tuberculosis, lung abscess, lung cancer necrosis |
