What diseases can be detected by CT scan?

Under normal circumstances, CT scans may detect diseases such as pulmonary nodules, lung inflammation, bronchiectasis, coronary artery atherosclerosis, lung cancer, and others. If experiencing any discomfort, it is advisable to seek medical attention promptly. Detailed explanations are as follows:

1. Pulmonary Nodules

Pulmonary nodules refer to round or oval lesions in the lungs with a diameter less than 3 centimeters. CT scans can clearly visualize the lung structure and detect small pulmonary nodules.

2. Pneumonia

Pneumonia is a lung infection caused by bacteria, viruses, or other microorganisms. Patients with pneumonia may experience symptoms such as congestion, edema, and inflammatory exudation in lung tissues. CT scans can reveal the extent, density, and morphology of lung inflammation, aiding in assessing the severity of inflammation and evaluating treatment effectiveness.

3. Bronchiectasis

Bronchiectasis refers to the persistent dilation of bronchial walls due to chronic inflammation or fibrosis. CT scans can clearly display the morphology and structure of the bronchi, identifying the location, severity, and type of bronchiectasis, thus providing a basis for clinical diagnosis and treatment.

4. Coronary Artery Atherosclerosis

Coronary artery atherosclerosis refers to plaque formation in the coronary arteries due to the accumulation of cholesterol and other substances, leading to arterial wall narrowing or occlusion. CT scans can assess the degree of narrowing in the coronary arteries, the nature of the plaques, and the extent of calcification.

5. Lung Cancer

Lung cancer is a malignant tumor occurring in the lungs. CT scans can identify the location, size, shape of the tumor, and its relationship with surrounding tissues, aiding in determining the pathological type and prognosis of lung cancer.

Prior to undergoing the examination, it is important to communicate thoroughly with the physician to select the appropriate diagnostic tests. Additionally, staying relaxed and avoiding excessive anxiety can help ensure the smooth conduct of the examination.
