Hagerstown Imaging provides a variety of high-quality medical and diagnostic imaging services. Hagerstown Imaging is also involved in brain research projects for funded grant projects with major national institutions.
How does a PET Scan work?A PET Scan integrates two technologies to view your body. Computed Tomography (CT) and a radioactive material (tracer). The tracer is what allows doctors to see how your body tissues absorb and use different chemicals.
PET Scans allow doctors to measure a range of activity, including blood flow, blood volume, oxygen usage, tissue PH (acidity), glucose (sugar) metabolism and drug activity. PET is very useful in watching the activity of cancerous tumors. Due to the fact that the malignant cells grow at such a fast rate, they metabolize more sugar than normal cells and can give your doctor a glimpse into how aggressive a tumor is or how its growth is slowed by treatment therapies.
A specially trained nuclear medicine technologist will perform the test. Our physician will review the images and report the findings.
Other common uses of PET are in field of Neuropsychatric Disorders. For example PET is useful in pre-surgical evaluation of medically uncontrolled seizures. By detecting metabolic changes in the brain, the surgeon can pinpoint the nonfunctioning area of the brain causing seizures.
PET can also help in diagnosing Dementia and to differentiate Alzheimer’s disease from other causes of Dementia. PET can also stage vasious brain tumors and help to differentiate residual or recurrent tumor from radiation necrosis.
How does a CT Scan work?CT rapidly creates detailed pictures of the body, including the brain, chest, spine and abdomen. It is able to detect and localize changes in the body structure or anatomy, such as the size, shape and exact location of an abnormal growth, a sizeable tumor or a musculoskeletal injury.
The test may be used to:
Our physician evaluates damage to the organs from any cancer that has spread (metastasized) from other areas. PET Scans often reveal problems much earlier than typical X-rays and have become a valuable screening study and a tool for assessing response to therapy for cancer that has spread to the organs.
