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.
This test uses a magnetic field, radiofrequency pulses, and a computer to produce detailed images of body structures in multiple planes. Some people may need an IV put in place so caregivers can inject a contrast solution into their veins. This depends on the exam the doctor has ordered. 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.
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.
To understand how well your lungs are working, your physician may order a series of pulmonary function tests. With each breath you take in and breathe out, information is recorded about how much air your lungs take in, how the air moves through your lungs and how well your lungs deliver oxygen to your bloodstream.
A biopsy is when your doctor removes a small piece of tissue from an organ, muscle, or growth. Biopsies of your organs or muscles can be used for to diagnose various conditions or abnormalities, including cancers, inflammatory diseases, and more. In some cases, a biopsy may remove the entirety of the abnormal tissue.
