Isotope Bone Scan Procedure
Can osteomalacia be misdiagnosed I have pain all over body no swelling ra factor ana prof normal isotope bone scan normal CBp tsh normal what to do have extreme pain on weigh bearing everywhere?
Overall body pain: Is classic for osteomalacia. On the other hand, the question is how this diagnosis was established and why you would at a relatively young age have this condition. Are your vitamin D levels low? Do you have in your muscles or only your joints? What is your serous calcium level? Parathyroid hormone? Fibromyalgia? I have more questions than answers. You need to see an MD in person for a diagnosis. ...Read more
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
My dad had a nuclear bone scan. Nuclear bone scan findings: there are several focal areas of isotope accumulation in the region of the sacroiliac joints bilaterally which correspond to lesions noted on the CT pelvis consistent with bony me
Possibly metastases: Nuclear bone scans usually demonstrate areas of increased bone metabolism, the bone reacting to a stimulus, such as tumor, fracture, infection, etc.Bone scan is very sensitive but not specific. Ct and MRI are cross sectional imaging that can more specifically identify the pathology and characterize the abnormalities on bone scan. ...Read more
Imaging of skeleton: Bone scans differ at different institutions. All involve IV injection of radiopharmaceutical usually tc99m mdp, related to phosphorous, deposited in skeleton. Scan one or more phases. Immediate imaging after injection (angiographic phase) for minute, then soft tissue imaging 5 to 15 min after injection. All involve delayed imaging at 2-3 hours after injection. Part or whole body imaged with camera. ...Read more
How am I being determined a candidate for a Fulkerson procedure or not after failed lateral release by my dr ordering a bone scan?
Not likely as B Scan:
Will not help in making that determination. He will take a proper HX and do a clinical Exam to ensure the Dx is in keeping with your symptoms. He might have to repeat LR again, by open means (if the first time it
was done arthroscopically).
Generally a Bony procedure is indicated if the soft tissue procedures failed or if the cause is bone-related.
Good Luck. ...Read more
After failed lateral release, my surgeon is thinking about doing a Fulkerson procedure, but wants to do bone scan 1st. Purpose of bone scan?
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
What is the purpose of having a bone scan for my knee before my dr making a final decision about doing a Fulkerson procedure?
To see if damage: It may be to look for damage of the bone and joint including the patella. Your physicians can clarify what the bone status is before surgery. I assume your slipping patella is the reason for the surgery I would expect you have done a lot of physical therapy before the decision for surgery is to be made. A strong quadricepes muscle is important for the patella strength and stabilization ...Read more
Images calcium metab: Usually in adults the bone scan is used to detect metastatic cancer. It also is frequently used to evaluate for possible stress fractures in people with bone pain. There are many additional uses. It works by injecting a tracer that is taken up in bone similar to calcium. The small amount of radioactivity is then imaged with a camera (gamma or pet) utilizing fluorescence from the crystal. ...Read more
New bone matrix: The injection is something that your body uses like a phosphate (methylene diphosphonate). In general when your body makes new bone, it will "grab" some of this. In young people we see more uptake near the ends of bones where they are growing. All bones will pick a little up since we are always making new and loosing some of the old. Kidneys filter out the rest. ...Read more
Bone metabolism: 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 more

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 more
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. ...Read more
Increased activity: Strong uptake on bone scan means increased metabolic bone activity. This could indicate inflammation, fracture, infection, and/or bone tumor. These results usually are considered in the face of plain x-rays and exam to determine the diagnosis. Sometimes mri/ct scan are also needed. ...Read more
Yes: Tc-mdp is a common tracer used for bone scans. The delivery / localization of tracer relies on blood flow. Therefore areas of increased blood flow have higher delivery of tracer. In addition, any actively calcifying process can show tracer uptake. Liver metastases from colon cancer are often seen on bone scan. ...Read more

Both radiation: Nuclear medicine radiation is given internally via IV injection, ingestion, or inhalation for determination of function of organs of body. Isotopes have different half lives and decay at different rates. Ct/xray is external radiation for visualization of anatiomy and pathology. Both contribute to radiation dose. Both are ionizing radiation. Ultrasound and MRI do not involve irradiation. ...Read more
Depends type of scan: It depends on type of scan and the reason it is being ordered. And the reason you can not handle the IV contrast. Discuss the issues with your doctor. ...Read more
Usual venous access: Intravenous injection of radiotracer tc 99m mdp in vein most of time at elbow, hand, etc. Usual sites of blood withdrawal. Lie on table with gamma camera positioned over areas of interest. Sometimes camera will go 360 degrees around patient to get tomography of spine. ...Read more
Depends: Bone scan will usually show bone metastases (spread) from certain cancers that often spread to bone (for example prostate, breast cancer). Primary cancer in the soft tissues will usually not show on bone scan. Other things that will show up on bone scan include areas of bony degeneration or fractures. ...Read more
Normal: It means there are no abnormalities. That is good news. All the best. ...Read more
It depends: Bone scans are used to evaluate for bone infections, recent fractures, and bone cancer, and are not used to check for osteoporosis. Most people never need one. Bone density testing should start when there is a reasonable probability of increased fracture risk that would require treatment. So it depends on risk factors. A common age to start would be 50 for women or 70 for men. ...Read more
<10 yrs and 1-2 yrs: Generally, you should have a discussion with your endocrinologist after being on fosamaz for >6-7 years- they can review your progress and assess your risk to discuss whether continuing further will bring anymore benefit. Generally, many dr's consider ~ 10 yrs sufficient duration. No consensus on frequency of DEXA scans to check progress, but bone changes slowly...If high copayment, 2 years. ...Read more
I have been having pain in my bones all over. Dr ordered bone scan what is she looking for. She just said what processes might be going on.
Anatomy vs Physiolog:
X-rays look at the structure of the body, the anatomy.
Bone scans look at the physiology, or how the skeleton uses phosphate, a chemical in building bone.
Your doctor may be looking for signs of abnormal bone metabolism or arthritis. The bone scan may help determine what body part (s) may require more imaging (xrays, ct or mr) or further medical evaluation. ...Read more
