Diaphragm Tumor - Diagnostic Procedures

How are Diaphragm Tumors Diagnosed?

Tests used to detect diaphragm tumors include:

Computed Tomography (CT) Scan

Doctors order CT scans when they want to see a 2-dimensional image of your body, including a view of the lymph nodes. If contrast dye is used to improve the computer image, you may need to avoid eating or drinking for 4 to 6 hours before the test. Be sure to tell your provider prior to the test if you have any allergies or if you have 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.
