Study Notes
- Gallium bone scans help to detect metastatic tumors, locate infection or inflammation, and monitor treatment response.
- Radioactive exposure precautions are unnecessary for Gallium bone scans.
- Gallium and thallium scans are more sensitive than bone scans in detecting bone problems.
- Radioisotopes migrate to tissues of the brain, liver, and breast, which assists in detecting disease in these organs.
- Clients undergoing this scan will receive a radionuclide injection.
- The scan takes 30 to 60 minutes and may require sedation to help the client remain still.
- Repeat scanning occurs at 24, 48, and 72 hours.
DEXA Scan
- Used to screen for early changes in bone density, commonly in the hip or spine.
- A peripheral DEXA scan assesses bone density in the heel, forearm, or finger.
- DEXA scans utilize two beams of radiation.
- Computer analyzes findings, and a radiologist interprets them.
- Clients receive a T score, relating their bone density to that of young, healthy adults.
- A Z score compares the client's bone density to that of age-matched individuals, serving as a control.
- During the scan, the client lies on an X-ray table while a selected area is scanned.
- Clients do not receive contrast material.
- Clothing is generally not removed, but metallic objects that could interfere with the scan should be.
- The scan estimates bone mass density, typically in the hip or spine, to determine the presence and extent of osteoporosis.
- Clients receive a score relating their bone density to others with similar demographics.
- These scores are not sex-specific.
- DEXA scans determine bone mineral content and bone density.
- Clients must remove metallic objects before the test.
EMG Test
- With nerve conduction studies, it can determine whether motor neuron issues or peripheral neuropathies are the cause of nerve issues.
- EMG and nerve conduction studies determine the presence and cause of muscle weakness.
- Clients undergo EMG testing at the bedside or in an EMG lab.
- A technician places thin needles into the muscle under study then electrodes attach to the needles, connecting to an oscilloscope, to record muscle contraction activity.
- Evaluable of muscle weakness and differentiation of muscle diseases from neurological conditions are possible during this test.
- Patients should avoid stimulants or muscle relaxants before the procedure.
