An arthrogram is a specialized imaging procedure for the joints, utilized as an alternative to standard X-rays. A radiosensitive dye is injected into the joint by means of a needle, and then photographed using X-rays, fluoroscopy, computerized tomography (CT) scanning, or magnetic resonance imaging (MRI). Arthrograms are most often used with major joints, such as the knee, shoulder, hip, elbow, wrist, or ankle.
Barium Enema of the Lower Gastrointestinal (LGI) Exam
A barium enema test is a diagnostic procedure that uses a contrast agent called barium to produce x-ray images of your lower gastrointestinal (GI) tract. If you receive an air contrast (double contrast) barium enema, air will also be used as a second contrast agent to expand the colon and produce a better picture. A fluoroscopy is used to see the contrast dye inside the GI tract. The barium solution highlights the areas of tissue being examined in order to show a clear picture of the colon.
Barium Swallow Test of the Upper Gastrointestinal (G.I.) Exam
An upper G.I. (UGI) examination is a diagnostic procedure that uses a contrast agent, called barium, to produce images of your upper gastrointestinal tract, including the esophagus, stomach and small intestine (small bowel). Using a type of x-ray, called Fluoroscopy, the UGI exam can detect problems with your upper digestive system.
Bone Density Test
Bone density testing is used to detect osteoporosis in order to determine your risk of a fracture. Bone density testing measures the calcium and other minerals in your bone and gives a “score” on two different scales to help your doctor diagnose osteopenia or osteoporosis.
A breast ultrasound, also called sonography, is an imaging technique in which high-frequency sound waves are bounced off tissues and internal organs (in this case, the breast). Their echoes produce a picture called a sonogram. Ultrasound imaging of the breast is sometimes used in conjunction with mammography to evaluate areas of concern.
Comprehensive Metabolic Panel
A comprehensive metabolic panel is a series of blood tests that provides information about your body’s chemical balance and metabolism. These tests measure 14 different substances in your blood, ranging from glucose to the total amount of protein.
CT or CAT Scan
CT or CAT scan stands for computerized axial tomography. This type of imagery uses an X-ray tube that travels 360 degrees around your body while gathering information from multiple views to create cross-sectional images.
A discogram, or discography, is an invasive procedure. During a discogram, dye is injected into the injured discs of your spine. Then, X-rays are used to examine the discs and make a diagnosis. The dye that is injected makes the discs visible on the X-ray. Discograms are used to determine which discs are injured and causing back pain.
An echocardiogram, or echo, is a noninvasive procedure that uses ultrasound to show how your heart muscle and valves are working. During this procedure, moving pictures are created of your heart, capturing its size and shape.
An endoscopy is a minimally invasive procedure that allows doctors to see tissue or organs in detail without having to make a large incision. During an endoscopy procedure, a long thin tube with an attached camera is inserted into an opening in the body, such as the mouth, anus or through a small incision.
Fluoroscopy is a type of imaging that shows a continuous X-ray image on a monitor. Instead of taking one still image, as with a traditional x-ray, fluoroscopy allows the radiologist to see movement of the body by creating an image of an instrument or dye (contrast agent) as it moves in or through the body.
Interventional radiology, or IR, is minimally invasive and often used as an alternative to open or laparoscopic surgery. Doctors use medical imaging including fluoroscopy, MRI, CT, and ultrasound to guide IR procedures.
Ultrasounds are a noninvasive, sound wave technology for producing images of bodily organs and structures. Kidney ultrasounds, also called renal ultrasounds, specifically target the kidneys and bladder. A device known as a transducer is placed on the patient’s skin. It emits sound waves, which penetrate the body, bouncing off organs and generating data that a computer transforms into on-screen images.
For mammogram screening, technicians use digital mammogram screening equipment. This includes flexible paddles that measure breast thickness, examination tables, open MRI machines, and 3D technology for comprehensive and accurate screening and diagnosing.
Magnetic resonance imaging (MRI) uses magnetism 20,000 times stronger than the Earth’s magnetic field to produce remarkably clear and detailed images of your head, spine, knee, shoulder or other parts of your body.
Nuclear medicine uses a small quantity of radioactive material combined with pharmaceuticals to look at the function of the body part rather than the anatomy, as with traditional x-ray. The nuclear medicine gets injected into the body part being scanned and is measured as it moves through that body part.
Radioactive Iodine (RAI) Treatment
Radioactive iodine treatment, or RAI, is a form of nuclear medicine that is proving successful in treating two types of ailments: overactive thyroid, also called hyperthyroidism, and papillary and follicular thyroid cancers. Located in your throat, the thyroid helps to regulate your body’s metabolism through the release of hormones. RAI is effective in killing cancerous or overactive thyroid cells because it is the only organ in the body that absorbs iodine.
A sigmoidoscopy is a minimally invasive test that examines the lower part of the colon, or sigmoid colon. It is conducted by placing a long, thin tube with a light and camera attached to it into the anus. This device is called a sigmoidoscope and it can both capture images and remove samples of tissue from the lower colon for examination.
An Ultrasound scan is a medical test that uses high frequency sound waves to make images or "see" the internal organs in your body. Ultrasound does not use X-rays, or radiation. An ultrasound creates images of soft tissue (showing density and form), it detects tumors (cystic vs. solid) and lesions, gallstones, kidney stones, and it images blood flow. Ultrasound exams are most commonly used to study a developing fetus, abdominal and pelvic organs, thyroid, blood vessels and the heart.
Ventilation-Perfusion (VQ) Scan
A ventilation-perfusion (VQ) scan measures airflow (ventilation) and tracks blood flow (perfusion) in the lungs. A VQ lung scan is considered a single procedure, but involves two separate scans. Both use a very restricted amount of radioactive material to capture images of the lungs. To help capture an image that measures airflow, the radioactive material is inhaled through a nebulizer. To help capture an image that tracks blood flow, the radioactive material is injected through a vein in the arm.
An x-ray is used to diagnose fractured bones or dislocated joints by using a small amount of radiation that is passed through the body, which records an image digitally or on film.
Different body parts absorb radiation differently so bones show up as white, tissue shows up as gray and air shows up as black.
