Chest CT examination can check whether the size and shape of the heart are abnormal, and also help to diagnose pericardial lesions and large vessel lesions. Chest CT is an examination of the chest using X-ray computed tomography, which can diagnose abnormalities in the chest wall, lungs, mediastinum, and other parts of the chest, as well as preliminary diagnosis of abnormalities in the size and shape of the heart. In addition, chest CT can help diagnose pericardial lesions such as fluid accumulation, calcification, and pericardial defects in the pericardium. Some patients can also be diagnosed with aortic aneurysm, aortic coarctation, pulmonary embolism, and other large-vessel disease and coronary atherosclerotic heart disease through chest CT. If you want to clearly diagnose whether the heart is abnormal, you should further choose to do multi-row spiral CT examination, cardiac ultrasound, 24-hour dynamic electrocardiogram and other tests, and combined with the symptoms to diagnose the disease. It is recommended that people with recent cardiac discomfort, such as pain in the precordial region, palpitations, chest tightness, etc., should seek medical attention as soon as possible to prevent accidents.
