Hi, I had a question. I recently had a whole body Nuclear Medicine bone scan done and the report says "Unremarkable tracer localization is seen in the osseous structures, what does this mean?

Hi, I had a question. I recently had a whole body Nuclear Medicine bone scan done and the report says "Unremarkable tracer localization is seen in the osseous structures, what does this mean?

Bone scan: The fact that the interpreting md. Stated it appears unremarkable is an indication that your scan is normal. The description about the distribution is the regular venacular describing the normal uptake by the bone (osseous means our bony skeleton) of the material that has been injected.

Bone (Definition)

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

On a whole body bone scan what does faint activity seen associated with the manubrial clavicular junction on the right side may be variation of normal?

On a whole body bone scan what does faint activity seen associated with the manubrial clavicular junction on the right side may be variation of normal?

All the scan tells-: -you is there is more bone active in that are, does not tell you why. Can be as simple as this being your dominant extremity. Very dense uptake is something significant & should be investigated.

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?

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.

Autoimmune disease: Despite negative labs, you may still have some type of autoimmune disease. Chronic pain throughout the body is usually due to autoimmune disease. If there is no anatomic distribution of the pain, and it's not related to disease such as infection, cancer, endocrine disease, then it must be autoimmune.

How can you have chronic joint pain. Stiffness, achey, puffy hands& ankles but have a normal nuclear bone scan of entire body? Also have neuropathy.

A bone scan: Will light up in regions of increased bone turnover like in a fracture or infection. Just because there is inflammation in a joint or pain does not mean the scan would light up. Neuropathy, like wise, would not cause a bone scan to light up.

How does nuclear medicine do a bone scan?

How does nuclear medicine do a bone scan?

Tc-99m-MDP Bone Scan: Bone scan often provides an earlier diagnosis and demonstrates more lesions than are found by radiographic procedures. Tc-99m-mdp (methylene diphosphonate) is a bone seeking agent that concentrates in the mineral phase of bone. 2-3 hours after injection, 50%-60% of the activity localizing in bone and the remainder is cleared by the kidneys. F18-naf bone scans are done with pet cameras, r + expensive.

Hello docs, is a full body bone scan like a gallium scan?

No: Gallium scanning involves greater irradiation and is non specific for tumor, infection, and bone abnormalities. Low radiation bone scan is specifically for osseous problems such as fractures, metastatic disease to bone, avascular necrosis, some metabolic bone issues, etc. Patient with unknown source of fever or pain and multifocal disease usually helped by bone scan.

Is it odd that a nuclear bone scan would not detect 2 rib fractures?

Is it odd that a nuclear bone scan would not detect 2 rib fractures?

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.

What exposes the body to more: radiation bone scan or computed tomography?

What exposes the body to more: radiation bone scan or computed tomography?

CT vs bone scan: The amount of CT radiation exposure depends on the type of CT. Average effective radiation dose for bone scan is about 6 mSv. Dose for head CT is 2mSv, for abdomen CT is 8 mSv, and for CT angiogram 16mSv.

Which exposes the body to more radiation bone scan or computed tomography?

Which exposes the body to more radiation bone scan or computed tomography?

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.

Can I have sexual intercouse after I have a bone scan while the nuclear chemicals are still in my blood?

Yes.: A woman who is pregnant or breastfeeding should notify the clinic before receiving the radiotracer injection, but there are no restrictions for sexual intercourse.

Got kidney removed 20 days b4 so the Injection given b4 Bone scan is it safe n whatever given through injection is tht excreated from body easily??

Got kidney removed 20 days b4 so the Injection given b4 Bone scan is it safe n whatever given through injection is tht excreated from body easily??

Yes...: The tracer which is given for bone scan is Technetium 99m MDP and it is excreted by the kidneys. The tracer is a radionuclide and has a physical half life of about 6 hours. This means that even if you had no kidneys, half of the tracer would have decayed by 6 hours. If you have kidney function, this will accelerate washout of tracer from your body and more than half will be gone by 6 hours.

Nature of bone pain with Vit D insufficiency or fibromyalgia - is it diffuse/general or can it be localized? Nuclear bone scan negative 4 osteo issues

Proximal vs general: Fibromyalgia pain is usually a generalized and diffuse muscular distress. Typically in low vitamin D (if severe) you will encounter a condition called osteomalacia which is associated with more localized proximal shoulder/hip girdle muscle achiness.

Do I need to stop taking calcium supplement before full body bone scan?

Do I need to stop taking calcium supplement before full body bone scan?

No it will not--: -effect it, the scan shows areas of bone that are undergoing activities related to arthritis, growth plates, & infection & tumors where bone is remodeling.

Question-results of a total body bone scan- the remainder of the axial and appendicular skeleton is without increase in activity. What is the meaning?

Question-results of a total body bone scan- the remainder of the axial and appendicular skeleton is without increase in activity. What is the meaning?

Rest of bones normal: Wording of "remainder" in report strange unless it initially mentioned in report some abnormality. The entire skeleton consists of appendicular and axial skeleton.

What can a nuclear bone scan show (about my hip bones) that cannot be seen by x-ray?

What can a nuclear bone scan show (about my hip bones) that cannot be seen by x-ray?

Bone scan: A nuclear bone scan may show hairline fractures, bone loss, infection or small tumors not visible on xray. It may also confirm the presence of arthritis that may be suspected on xray.

Tkr, feb.2012. Pain, bone scan, sept 2013, possible infection, loosening, trauma. Nuclear med. Test oct 2013, no infection. No loosening. What now?

TKR: Infection of an indwelling prosthesis will often require removal of the prosthetic knee, placement of a spacer, long term antibiotic therapy, followed by replacement of the prosthesis after assessment of efficacy of treatment, and then continued long term antibiotics. See an infectious diseases expert.

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.
