| -gram | record |
| Angi/o | vessel (blood) |
| Anteroposterior | AP) view. X-rays travel from an anteriorly placed source to a posteriorly placed detector. |
| Computed tomography | Diagnostic x-ray procedure whereby a cross-sectional image of a specific body segment is produced. Newer CT scanners can create 3D images as well. |
| tom/o | to cut |
| -graphy | process of recording |
| echo- | a repeated sound |
| Fluor/o | luminous |
| In vitro | Process, test, or procedure is performed, measured, or observed outside a living organism, often in a test tube. |
| in vivo | Process, test, or procedure is performed, measured, or observed within a living organism. |
| Interventional Radiology | Therapeutic or diagnostic procedures performed by a radiologist. Examples are needle biopsy of a mass and drainage of an abscess, typically under the guidance of CT, ultrasound, or fluoroscopy |
| Lateral decubitus | a position in which a patient lies on his or her side and which is used especially in radiography and in making a lumbar puncture. |
| Myelography | X-ray imaging of the spinal cord (myel/o) after injection of contrast agent into the subarachnoid space surrounding the spinal cord |
| myel/o | spinal cord; bone marrow |
| Recumbent | lying down (may be prone ot supine)) |
| Nuclear Medicine | Nuclear medicine, also known as nucleology, is a medical specialty that uses radioactive substances to diagnose and treat diseases. |
| Oblique | X-rays travel in a slanting direction at an angle from the perpendicular plane. Oblique views show regions or structures ordinarily hidden or superimposed in routine PA and AP views. |
| Posteroanterior | PA) view. In this most commonly requested chest x-ray view, x-rays travel from a posteriorly placed source to an anteriorly placed detector. |
| Pyel/o | renal pelvis |
| -lucent | to shine |
| Radiolucent | Radiolucent (indicating that x-rays pass through easily) areas on x-ray images appear dark |
| -opaque | obscure |
| Radioisotope | Radioactive form of an element substance; radionuclide |
| son/o | sound |
| tom/o | Tom/o means to cut, as in viewing in slices |
| ultra- | beyond |
| Contrast studies | Radiopaque materials (contrast media) are injected to obtain contrast between tissues that would be indistinguishable from one another |
| Radiopharmaceutical | Radioactive drug (radionuclide plus chemical) that is administered safely for diagnostic and therapeutic purposes; a radiotracer. An example is technetium-99m, which combines with albumin (for lung perfusion) and DTPA (for renal imaging). |
| pharmaceut/o | drug |
