Pneumonia, stethoscope. Can you tell?

Usually, if the patient has pneumonia, you can hear the moist rales in the patient's lungs with a stethoscope, but most people still recommend that the patient do a CT scan of the lungs to see if there are any imaging changes of pneumonia. Also, if the patient has cough, expectoration, high fever, and related inflammatory indicators, such as white blood cells, C-reactive protein, and procalcitonin, to judge whether the patient has pneumonia.
