Emphysema
Diagnosis

In making a diagnosis of emphysema, your doctor will start by conducting a thorough medical examination, recording your medical history and asking about any symptoms you are experiencing.

The following tests may then be conducted to make a definite diagnosis:

  • Pulmonary Function Testing (PFT) This test involves a series of breathing maneuvers that measure the airflow and volume of air in your lungs. This allows your doctor to objectively assess the function of your lungs.
  • High Resolution Computed Tomography (HRCT) This is a special type of CT scan that provides your doctor with high-resolution images of your lungs. Having a HRCT is no different than having a regular CT scan; they both are performed on an open-air table and take only a few minutes.
  • Chest X-Ray Chest X-rays can help confirm a diagnosis of emphysema and rule out other lung conditions.
  • Arterial Blood Gases Analysis These blood tests measure how well your lungs transfer oxygen to your bloodstream and remove carbon dioxide.
  • Sputum Examination Analysis of cells in your sputum can help determine the cause of some lung problems.
