CT stands for Computed Tomography. CT offers detailed information by taking cross-sectional images throughout the body via a helical scanner. CT scan, like conventional x-ray, uses radiation. Depending on the type of exam your physician orders, you may have to drink a flavored liquid before your exam (oral contrast) and/or receive an injection of contrast material. Contrast allows for better visualization of certain organs within the body. Exams take 5 to 20 minutes.
Fluoroscopy is a form of diagnostic radiology that enables the radiologist, with the aid of a contrast agent, to visualize the organ or area of concern via the x-ray. This contrast agent allows the image to be viewed clearly on a television monitor or screen. The contrast agents may be introduced into the body through injection, swallowing, or an enema.
Mammography is a specific type of imaging that uses a low-dose x-ray system to examine breasts. A mammography exam, called a mammogram, is used to aid in the early detection and diagnosis of breast diseases in women. Mammograms are used as a screening tool to detect early breast cancer in women experiencing no symptoms and to detect and diagnose breast disease in women experiencing symptoms such as a lump, pain or nipple discharge.
MRI stands for Magnetic Resonance Imaging. It is a diagnostic imaging test that uses strong magnet and radio frequency waves to produce images of internal organs and structures. MRI is a non-invasive procedure, however, your physician may request a contrast agent be used to better visualize organs or structures. If this is requested, you will receive an injection of the contrast agent during your examination.
Nuclear Medicine is a radiological field that uses safe and painless techniques to image the body and treat disease. Nuclear Medicine techniques can make it possible to gather information on the function and structure of the organs that may otherwise require surgical intervention or other tests. Nuclear medicine is commonly used to measure or detect hyperthyroidism, heart function, orthopedic injuries, blood clots in the lungs, and liver, and gall bladder functions.
An ultrasound produces sound waves that pass into the body and sends echoes back to produce images of the internal structures of the body. These sound waves are not harmful to the body or a fetus. Ultrasound can also show internal motion such as blood flowing through the veins and the heart beating. The sound waves are produced from a microphone like device that the technologist moves over the area to be examined.
General diagnostic exams may be ordered by your physician to diagnose conditions in the chest, bone, sinuses, skull, or spine. It is the oldest and most frequently used form of medical imaging. X-ray is the fastest and easiest way for a physician to view and assess broken bones. It can also be used to diagnose and monitor the progression of degenerative diseases.
