CT is more accurate in detecting emphysema.
CT examination is a relatively common imaging examination, which can see the manifestations of small airway lesions of chronic obstructive pulmonary disease and emphysema, but its main significance is to exclude respiratory manifestations with similar symptoms.
Clinical diagnosis of emphysema often needs to be combined with the patient’s clinical symptoms and relevant auxiliary tests, such as pulmonary function tests, bronchodilator test, blood tests, blood gas analysis, etc..
In addition, CT examination is also divided into ordinary CT and enhanced CT, and the accuracy of emphysema examination will be higher if it is enhanced CT.
If emphysema is suspected by CT examination, further examination can be taken according to the doctor’s instruction to confirm the diagnosis and take early treatment.
