Mesothelioma Imaging Scans

Doctors use imaging scans, such as X-rays, CT scans, MRIs and others, as noninvasive tools that help detect tumors in the body when a patient experiences symptoms usually associated with an asbestos-related disease like mesothelioma.

Because the symptoms of mesothelioma match those of other diseases, mesothelioma can be difficult to diagnose and locate. The tumors may show up in any part of thin layer that surrounds the organs. They can even be found between organs. For this reason, it is important to use advanced imaging technology to assist with proper diagnosis.
A cancer doctor begins a patient examination with a thorough review of the patient's medical history. As the diagnosis process continues, there may be several tools used simultaneously to get the most accurate results. Along with blood tests and other examinations, a medical professional may use one or more noninvasive body scans to detect any abnormalities.

X-rays

The most basic imaging scan is an X-ray. This scan is limited, but may be able to detect damage or abnormalities in the body. One of the biggest drawbacks of an X-ray is that it can only produce a flat, two-dimensional image. When an X-ray is taken, electromagnetic radiation is sent through the body with a photographic film on the other side. The way the waves, or rays, behave will change as they pass through the body, creating a representative image.

• Only flat, two-dimensional images
• Most common imaging technique
• Radiation level not harmful

Tumors

On standard X-rays, healthy lungs appear black. When a tumor is present on the pleura, doctors will see a wispy white area that indicates tumor growth. Tumors can also distort the normal shape of the lungs, which can be detected on the radiograph. A tumor-encased lung appears compressed and can show an elevated diaphragm.

Radiation

One single chest X-ray exposes patients to the same amount of radiation they would naturally encounter over a period of 10 days. This exposure generally does not cause any serious side effects. However, patients are encouraged to hold on to copies of their results to avoid the need for unnecessary duplicate tests over their lifetime.
