RADIOLOGY/DIAGNOSTIC IMAGING TERMS (CONTINUED)
Here are some additional terms used in the field of radiology. This glossary may help you understand the tests that have been performed or that your physician are suggesting be performed. These terms may also assist you in reviewing your medical records.
Myelogram
A myelogram is used to evaluate the discs between a patient’s vertebrae. A needle is used to inject contrast fluid into the thecal sac. The thecal sac houses the nerve roots. The needle is placed in the spine with the assistance of fluoroscopy (see “fluoroscopy” in radiology/diagnostic imaging terms). X-rays are then taken to assist in diagnosing pathology associated with one or more discs and/or degenerative changes in the patient’s spine.
Angiogram
An Angiogram is used to visualize issues affecting a patient’s blood vessels. Contrast fluid is injected to an artery and x-rays are then taken of the injected vessel. Angiography is also used in combination with Magnetic Resonance Imaging (MRI) or Computerized Tomography (CT). Occasionally, contrast fluid is not needed. Certain angiography techniques also utilize Doppler Ultrasound (Doppler Duplex Ultrasound).
Diskogram
When a Diskogram is performed, a needle is placed into an intervertebral disk under fluoroscopic guidance. Iodine contrast material is injected. Radiographs or X-rays are obtained. The patient is also involved by confirming whether or not there is a sensation associated with the injection. CT imaging is also used in certain diskogram procedures.
Arthrogram
In an Arthrogram test, a needle is placed into a patient’s joint. Iodine contrast is injected. X-rays are obtained. An arthrogram may help a doctor discover a ligament tear or cartilage pathology. An arthrogram is often effective to assist in evaluating the internal characteristics of a patient’s joint. An arthrogram may be combined with Computerized Tomography (CT) to assist in certain cases where a plain film arthrogram does not give complete enough visualization of the issue affecting the patient’s joint. Arthrograms can be used in conjunction with Magnetic Resonance Imaging (MRI).
Bone Scan
A Bone Scan can also be called Bone Scintigraphy. With this test, a radioactive dye is injected into the bone being studied. Radiographic images are taken of the bone which reveal how the dye travels through the bone. Normal bone function and formation is revealed as is abnormal bone function and formation.
