Nuclear Bone Scan
Bone abnormalities: Bone scan involves intravenous injection of radio tracer usually technetium 99m mdp which accumulates in skeleton. Scan may involve early phase(5-10 min) and late phase(2-3 hr) imaging. Increased uptake is seen in fractures, tumors, infection, etc. Decreased activity is seen in metal artifacts, aggressive tumor/infection, & loss of blood supply to bones. Bone scan very sensitive but not specific. ...Read moreSee 2 more doctor answers
Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more

No iodine bone scan: Nuclear medicine bone scans are performed using a radionuclide called tc 99m mdp. It is a radioactive particle tagged to a molecule involved in bone metabolism. Common exam, around for decades. There is now a new scan using a pet/ct scanner and an isotope sodium flouride. It is sensitive and more accruate but also more expensive and less available. ...Read moreSee 1 more doctor answer
PET/CT scan: You need to fast for 4 hours first, then you will recieve an injection of a small amount of radioactive glucose (i.e. Sugar). Next you will sit in a recliner chair for about 70 minutes to allow the glucose to distribute throughout you. Then you will lie on your back on the pet/ct scanner (a tunnel shaped machine) for 20 minutes. There are no side effects from the test or restrictions afterwards. ...Read moreSee 2 more doctor answers
UltraSOUND: I think you mean cardiac ultrasound (also known as echocardiography). They look at different things. Echo sees over all function, wall thickness, chamber dimensions, valves, and can measure blood flow and pressure. Ct is for detecting calcium and looking at the coronary arteries. ...Read more
Quite different: Ct involves xray type radiation with cross sectional imaging in transaxial, sagittal, and coronal projections. Nuclear medicine, internal irradiation either injected intravenously, inhaled, ingested, injected subcutaneously.Ivp uses injection of contrast material for visualization of kidneys and bladder with x-ray. Mr imaging uses no ionizing radiation magnetic fields to generate x-sectional images. ...Read more
Not great: X-RAYs are relatively insensitive in the detection of early or small metastatic lesions. Although CT scans are superior, CT scanning is relatively insensitive in showing small lesions, and it has the disadvantage of limited skeletal coverage. Bone scans are very sensitive (they'll pick up everything) but nonspecific (could be just arthritis). MRI and PET scanning are accurate but very expensive. ...Read moreSee 1 more doctor answer
Very safe: Injection of isotope technetium 99m mdp and visualization of skeleton looking for areas of abnormal uptake. Side effects include sometimes some bleeding from injection site. Isotope usually does not cause any allergic reaction. Lie down on table with cameras taking images of skeleton. Relax. ...Read moreSee 1 more doctor answer
Not quite: The CT of the sinuses focuses in on the sinuses (though the radiation goes through the entire skull) and generally covers the entire set of sinuses (sphenoid, maxillary, frontal, ethmoid). The orbital CT will cover the eye sockets (and those pictures are zoomed in). While the sinuses lies behind the eyes (& so they overlap), the focus & coverage of these scans are slightly different. ...Read moreSee 1 more doctor answer
Sometimes same dose: Background radiation at sea level: 3 msv per year, denver residents get: 6 msv per year, cross country flight: 0.02 msv, x ray chest: 0.06 msv, ct head: 3 msv, ct chest: 5 msv (equivalent to 100 chest xrays) ct abdomen: 5-10, average bone scan 6.5 msv. Radiation depends on size of patient." radiation affects growing body in children more than adults. Doses to children are much less. ...Read more
Different mechanisms: Mri uses magnetic radiation( no x-ray) for anatomic localization and characterization of different parts of body, water and fat constitution of different tissues.Ct uses x-ray to characterize anatomy of body, better for bone than mr.Pet, bone, gallium scans use radio tracers intravenously.Petglucose metabolism of tumors, gallium (infection/tumor), bone scan for fxs, tumors, infection bone metabolism. ...Read more
Osteomalacia: No. A Dexa detects osteoporosis, or decreased amount of bone matrix. Osteomalacia is an abnormal type of bone, soft bones, abnormal building process. You can have both osteoporosis/malacia, so dexa is still done in the workup to measure the amount of bone. Vit D deficiency, GI disorders that cause malabsorption, kidney disease, liver disease, certain drugs... all are part of the differential. ...Read moreSee 1 more doctor answer
Radiology/neurology. Ct scan shows bone, MRI shows soft tissue, so therefore can't indentify disease of skull bones. Intercrainial means misdiagnosis?
Yes: yes unless they use different medicineGet a more detailed answer ›
Not usually: Not usually nuclear medicine affecting ct but the opposite. However ct scan with intravenous iodine contrast materials can affect thyroid scans and thyroid uptake. Renal GFR studies using glofil with i125 are also affected by iodine contrast of ct. ...Read moreSee 2 more doctor answers

CTU and nuclear bone scan report a moderately functionally active right proximal femoral lesion. Associated pain, nausea etc. Should I be worried?
Difficult to know: Needs further detail such as when you have the pain, other associated features etc. I would recommend discussing with the doctor who ordered the test or failing that the GP as if it remains unclear they can examine you to interpret the result and if still not clear they'll be able to refer you to orthopaedics or rheumatology who will give you straight answers on this. All the best. ...Read moreSee 2 more doctor answers
No: Bone scan is a very sensitive way to detect recent bone fractures. However many factors will affect this ability to detect them such as the time interval between the fracture and the scan, the age of the patient, and the location of the fractures. In a young patient, bone metabolism can return to a normal status very quickly. Spect study ( tomography) is also very helpful to detect some lesions. ...Read moreSee 2 more doctor answers
Nuclear bone scan: can pepto bismol (bismuth subsalicylate) cause false positive results? False negative results? How likely @ just normal dose pepto (~1000 mg over 2 hours)?
Yes: Pepto bismol (bismuth subsalicylate) contains bismuth which can block the gamma ray photons which form the bone scan image. As a result bones of the lumbar spine or pelvis can show areas of diminished activity (cold spots) on images acquired from the front (anterior) due to bismuth in the bowel. Routine instructions advise against taking pepto bismol (bismuth subsalicylate) for a week before the bone scan. ...Read moreSee 2 more doctor answers
If impacted wisdom tooth is infected, and sends infection + pain to other parts of body, wud this show on nuclear bone scan + wud pain be severe?
Not normally: An infection usually tries to get out by way of the path with least resistance. Expansion in the area is definitely possible but movement more rare that it would spread. Make sure to see a dentist or Oral surgeon soon to evaluate the extent of the infection and the appropriate treatment. ...Read moreSee 1 more doctor answer
I had a nuclear bone scan and I don't understand the results. Activity in the ankles, the shoulder girdle and spine plate, uptake in thoracic spine?
1) what was the : Reason you had the scan? Where was your issue? Increased uptake can mean many things. A bone scan results must take patient history, clinical findings and not be looked at independently. Increased uptake can mean anything from arthritis, to fracture to infection....what did your doctor tell you? ...Read more

If Ana is negative do I need Ana profile hve joint pain on weight bearing rheumatologist hve noanswer tsh nuclear bone scan normal no swelling in join?
Use of test: The ANA has very limited use as a screening test. Nuclear scans are helpful in distinguishing inflammatory conditions (lupus, rheumatoid arthritis, myositis, etc.) versus non-inflammatory conditions. Pain with weight bearing and the lack of swelling suggest a mechanical cause. X-rays, MRI, and other tests may be more helpful than blood tests. ...Read more
Dull pain on weigh bearing rheumatologist think it's due to chronic vit d deficiency now vit d normal nuclear bone scan ra factor blood test normal can it be osteomalacia my alkaline phosphate normal?
Be patient: Rheumatologist are very knowledgeable, and evaluate this kind of condition several times daily. If your Vit D has been low for several months or years, then thinning of the bones is likely to have taken place. Normalizing the deficient level will not immediately bring about bone density improvement - it will take 1 to 2 years. Hopefully, your symptoms will start to improve within 6 months. ...Read moreSee 1 more doctor answer
