Valley Imaging is an outpatient diagnostic imaging center, providing the latest imaging technology including the revolutionary Positron Emission Tomography/Computerized Tomography (PET/CT), Magnetic Resonance Imaging (MRI), Computed Tomography (CT), ultrasound, vascular lab, and diagnostic x-ray.
PET/CT, or Positron Emission Tomography/Computed Tomography, is a nuclear medicine procedure that produces images of the body's biological functions. This exam is capable of detecting certain diseases because it is able to capture chemical and physiological changes related to metabolism. This is important since functional changes are often present before structural changes in tissues; therefore, demonstrating pathological changes long before they would be evident with conventional diagnostic imaging methods. The exam takes approximately two hours.
An injection called FDG (fluorodeoxyglucose) is produced specially for each patient and is time sensitive because of its natural decay. This makes it very important that you arrive on time for your study. First an injection is made, followed by a 30 minute resting period. You are then placed on the PET scanner bed with scanning time of approximately one hour.
The PET scanner is doughnut shaped and resembles a CT scanner. The signals emitted by the FDG are recorded and reassembled by the computer into images that contain vital information about tissue function. The test is highly sensitive and allows better diagnosis, staging and follow-up of patients undergoing therapy.
If you have been referred to us for a PET scan, you will be contacted by one of our scheduling staff members to discuss additional instructions for the study.
Computed Tomography (CT) or (CAT) scan uses a combination of very thin rotating x-rays and computer technology to produce detailed images of the body. The computer measures the intensity of x-rays, which are transmitted through the patient, and displays the information as an image on a monitor. A CT scan has the ability to look at an entire area of the body including bones, muscles, fat, and organs. It takes a "stack" of pictures, much like slices in a loaf of bread. CT images maybe 10mm to less than 1mm thick and are more detailed than diagnostic x-rays.
A sophisticated form of diagnostic imaging that uses magnetism, radio waves and computer technology to produce very clear, three dimensional images of the body without using radiation. MRI offers a painless, non-invasive way to obtain information about your body that can lead to early detection and treatment of disease and injury.
Preparing for an MRI
- No preparation is required for most MRI examinations. You may eat, drink or take medication prior to your examination.
- Some examinations require injection of MRI dye in a vein.
- If special preparation is required for your MRI examination, you will be given instructions at the time of scheduling.
For your safety, please tell us if...
- You have a cardiac pacemaker or artificial heart valve
- You have aneurysm clips
- You are pregnant or think you could be
- You have had inner ear surgery
- You have any other metallic medical bioimplant, prosthesis or foreign metal in your body
- You have or have had problems with kidney function
A standard x-ray (radiograph) is a diagnostic imaging test that helps physicians diagnose and treat medical conditions. X-rays are the oldest and most frequently used form of medical imaging involving exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. As the dose of radiation is very small, this is a very safe imaging study. The most common use of standard x-ray is for diagnosis of disease and/or injury to the bones and chest. Memorial's Valley Imaging standard x-rays are made with a digital system storing the images electronically.
Diagnostic ultrasound, which is sometimes called sonography, uses high frequency sound waves and a computer to create images. In addition to the traditional use to assess fetal development during pregnancy, ultrasound is used to examine many parts of the body, including the gallbladder, liver, spleen, kidneys, pancreas, uterus, ovaries, prostate and testicles. Vascular ultrasound can also look at and listen to the blood flow within arteries and veins in the neck, abdomen and legs.
