	Radiology (Bone Scan)
		The bone scan involves an injection, in the vein of your arm, of a Technetium-99m containing compound that localizes in the bone.
		Bone scanning is particularly useful because it is possible to evaluate the entire skeleton with a single examination.
		While performing the bone scan, side effects are not common, and when encountered are usually mild, such as nausea and vomiting.

	Bone Scan
		A bone scan is a nuclear scanning test that identifies new areas of bone growth or breakdown.
		For a bone scan, a radioactive tracer substance is injected into a vein in the arm.
		A bone scan may be done initially to help determine the location of an abnormal bone in complex bone structures such as the foot or spine.

	Bone Scan - B2.1
		Definition of Condition: Bone scanning (scintigraphy) is a nuclear study performed to assist in diagnosing pathological conditions as well as complications of bone disease.
		Issue Statement: Bone scans are used for the early identification of bone lesions and identifying the age of fractures.
		A bone scan may be positive as early as 24 hours after the onset of symptoms and may be positive and usually will remain positive until the lesion has healed completely.

	Bone scan: Using nuclear medicine to look for bone abnormalities - OhioHealth (Site not responding. Last check: 2007-10-09)
		A bone scan falls under the category of nuclear medicine, which means that it uses tiny amounts of radioactive materials called tracers (radionuclides).
		During the scan, you'll be asked to lie very still on a table while a machine with an arm-like device supporting the gamma camera passes over your body and records the pattern of tracer absorption in your bones.
		Although a bone scan is very sensitive to abnormalities in bone metabolism, it's less helpful in determining the cause of the abnormality, such as a fracture, infection or bone tumor.

	Bone nuclear medicine scan
		A bone scan is a diagnostic procedure used to evaluate abnormalities involving bones and joints.
		Bone scans are useful in diagnosing early arthritic changes, and monitoring both the progression of the disease and the effectiveness of treatment.
		During the scan, the patient lies on his or her back on a table, but may be repositioned to the stomach or side during the study.

	Bone Scan
		In a nuclear bone scan, the body is emitting the radiation to the surface, where it can be detected by the gamma camera.
		Bone scans are done on pregnant women to avoid radiation exposure to the fetus.
		During the scan itself, you lie still on a table while a machine with an arm holding the gamma camera passes over your body and records the pattern of radiation waves being emitted by your body.

	Secondary Bone Scan Findings
		A bone scintigram was negative for bone metastases.
		CT scan confirmed a mass which proved to be a poorly differentiated adenocarcinoma of Mullerian origin.
		The urinary tract is a major non-skeletal component of the bone scan since 45-50% of the radiopharmaceutical is excreted by the kidneys.

	Bone Densitometry (DXA or DEXA)
		DEXA bone densitometry is most often used to diagnose osteoporosis, a condition that often affects women after menopause but may also be found in men.
		Despite its effectiveness as a method of measuring bone density DEXA is of limited use in people with a spinal deformity or those who have had previous spinal surgery.
		But because bone mass tends to vary from one location to the other, measuring the heel is not as accurate as measuring the spine or hip.

	MedlinePlus Medical Encyclopedia: Bone scan
		A bone scan is a test that detects areas of increased or decreased bone metabolism (turnover).
		If a bone scan is performed to evaluate possible fracture or infection, images will be performed shortly after the radiotracer injection, as well as after a 3-hour delay, when the tracer has collected in the bones.
		Although it is extremely rare with bone scanning agents, a person may develop rash, swelling, or anaphylaxis (severe allergic response).

	Novartis Oncology - Bone Metastasis
		Bone is a type of connective tissue made up of minerals, such as calcium and phosphate, and the protein collagen.
		In a bone scan, the patient is given an injection of a low amount of radioactive material (much lower than that used in radiation therapy).
		Bone metastasis can cause a number of substances, such as calcium and an enzyme called alkaline phosphatase, to be released into the blood in amounts that are higher than normal.

	SPINE-HEALTH \| Diagnostic studies
		A bone scan is sometimes performed to rule out an inflammatory process (such as a tumor or infection) or an occult fracture (small fracture not seen on an x-ray).
		A bone scan is a highly sensitive test to pick up tumors, infections, or very small fractures because these conditions all result in high bone turnover.
		Bone scans, however, cannot distinguish what a lesion represents, and therefore cannot differentiate between a tumor, an infection or a fracture.

		Both bone and gallium scans may be needed for accurate diagnosis of SI joint infection.

		The patient is asked to arrive 3 hours before their actual scan to receive an injection of a small amount of radioactive tracer that is "tagged" to a calcium like material.
		A normal bone scan has symmetrical and uniform uptake of the tracer.
		An abnormal bone scan will appear as increased uptake of the tracer where bone formation is occurring faster than the surrounding bone.

		The reason, he said, was because even if a cancer has left the bone, if it had been eating into the bone and the bone is rebuilding, the new growth will show in the scan.
		Later, when the scan was completed and I was getting up from the miserably hard surface I had to lie on for what seemed like eternity, the technician who was doing the scan and knew my interest was at the computer console where the image appeared.
		She had pulled up the first scan from January and was pointing to some differences in the two images.
