Muscular System: Diagnostic Tests & Procedures
| Term | Definition |
|---|---|
| Deep Tendon Reflexes (DTR) | Evaluation of involuntary muscular responses with a reflex hammer. Patients under heavy sedation or in a deep coma do not show these reflexes. |
| Biopsy | The removal of a small piece of living tissue for microscopic examination. |
| Computerized/Computerized Axial/Computed Tomography | Process in which radiographic images of a specific section of the body are taken from multiple angles. A computer analyzes the images to identify muscular injury or disease. CT scans provide more detailed imagery than standard x-rays. |
| Electromyogram (EMG) | A graphic recording of the contraction of a muscle as a result of electrical stimulation. |
| Goniometry | The measurement of range of motion in a joint. |
| Magnetic Resonance Imaging (MRI) | A noninvasive scanning test that involves use of an electromagnetic field and radio waves to visualize soft-tissue structures. |
| Nuclear Medicine Imaging (NMI) | Diagnostic imaging technique in which a radioactive substance and a special camera visualize structures and functions in the body. The radioactive substance is injected into or swallowed by the patient. |
| Radiography | Diagnostic imaging techniques that use electromagnetic waves to create images of the inside of the body. X-rays check for structural abnormality or disease. |
| Range-of-Motion Testing (ROM) | Diagnostic procedure performed to evaluate the extent to which joints can be moved in a variety of directions. |
| Sonography/Diagnostic Sonography/Ultrasound | Diagnostic imaging method involving the use of high-frequency sound waves to generate images of structure in the body, such as muscles, ligaments, & displaced/dislocated structures. |
