Diagnosis

In addition to taking a detailed medical history and performing a physical examination, the patient’s surgeon may order tests to detect pleural diseases, including:

  • Arterial blood gas analysis

    To measure how well your lungs transfer oxygen from the blood and how well the lungs remove carbon dioxide

  • Biopsy

    Any suspicious mass of tissue or tumor is subject to a biopsy, or removal of cells from the mass. This is the only technique that can confirm the presence of cancer cells. The doctor will use a general or local anesthetic depending on the location of the mass, and then remove a sample of tissue to send to the lab. The sample is sent to a pathologist, a physician who is an expert at identifying diseased cells in tissue samples. Very often, a few stiches are used to help the area heal, and tenderness is felt for a short period of time.

  • Blood Tests

    A common tool for disease screening, blood tests provide information about many substances in the body, such as blood cells, hormones, minerals, and proteins.

  • Chest X-ray

    Chest x-rays provide an image of the heart, lungs, airways, blood vessels and bones in the spine and chest area. They can be used to look for broken bones, diseases like pneumonia, abnormalities, or cancer.

  • Computed Tomography (CT) Scan

    CT scans use x-ray equipment and computer processing to produce 2-dimensional images of the body. The patient lies on a table and passes through a machine that looks like a large, squared-off donut. Doctors order CT scans when they want to see a two-dimensional image of the body to look for tumors and examine lymph nodes and bone abnormalities. If contrast dye is used to improve the computer image, the patient may need to avoid eating or drinking for 4 to 6 hours before the test. Patients should tell their provider before the test if they have any allergies or kidney problems.

  • Magnetic Resonance Imaging (MRI)

    This test uses a magnetic field, radiofrequency pulses, and a computer to produce detailed images of body structures in multiple places. You may be asked to drink a contrast solution for better imaging, and you will most likely lie on a moving table as pictures are taken. MRI is a more detailed tool than x-ray and ultrasound and for certain organs or areas of the body, it provides better images than CT. MRI may not be recommended if you have a pacemaker or other metal implant.

  • Positron Emission Tomography (PET) scan

    A PET scan is used to detect cellular reactions to sugar. Abnormal cells tend to react and "light up" on the scan, thus helping physicians diagnose a variety of conditions. For the PET scan, a harmless chemical, called a radiotracer, is injected into your blood stream. Once it has had time to move through your body, you will lie on a table while a scanner follows the radiotracer and sends three-dimensional images to a computer screen. Patients are generally asked to wear comfortable clothing and refrain from eating for 4 hours before the scan. Tell your doctor if you are pregnant or breastfeeding. Patients with diabetes should discuss diet guidelines with their physician for the hours leading up to the scan.

  • Stress Test

    A stress test is used to gain more information about how your heart functions during exercise. Your physician will monitor your heartbeat and blood flow as you walk on a treadmill, and will then be able to diagnose any problems as well as plan treatment.

  • Thoracentesis

    A procedure to remove excess fluid in the space between the lungs and chest wall.

  • Ultrasound

    Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses high-frequency sound waves to produce images of structures within the body. The images can provide valuable information for diagnosing and treating a variety of diseases and conditions. Most ultrasound examinations are done using a sonar device outside the body, though some ultrasound examinations involve placing a device inside the body.
