Bone Scan Hot Spots White Or Black
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
Ca br, infiltr ductal 2b, er-pr+, her2-ve, since 4yr, tamo1yr&exemes3yr, on bone scan hot spots rt femur, left parietal, sacral, L5 but all xray normal-advice?
Bone scan normal except tracer uptake hot spots in both big toes. No pain here, labs neg for osteo + RA. Don't exercise, what else could explain this?
Had full body bone scan had mottled white spots on hands wrists and feet legs black on my upper spine and a big black spot on the side of my face?
Need more info...:
And I advise waiting for the official radiologist or nuclear physician report. What is seen on the technologist screen is not of the same quality as the physician interprets.
Also, some physicians read them where lighter means more radioactivity, and others where black does, so your description cannot be accurately commented on. ...Read more
Unable to answer: T1 images will show water, air, and cortical bone as dark. T2 images will show air, cortical bone, and other hydrophobic substances as dark. So depends on image acquisition and anatomy. ...Read more
Will lytic lesions light up on bone scan? Doesn't it just show osteoblastic activity, not -clastic? Or do osteoclastic maybe show up as "cold spots"?
Osteoclastic - cold: Lytic lesions can be cold (photogenic) on bone scan if host bone does not react or tumor growing too fast to allow host response with reparative bone. Some times bone infection will be under pressure and not allow blood to to deliver isotope to area and it will be cold. Osteoblastic or repair activity usually shows as increased uptake. Myeloma can induce osteoclastic activity, cold lesions in bone. ...Read more
Bone scan to check if a 6mm hemangioma in my T1. During the scan I saw white spots in my kidneys - one in each kidney. Is there hope it’s nothing?
Had bone scan today, showed white spots lower back and hips, why is this? Had bc 2005, stress fracture showed on normal xray
Degenerative changes: I assume the image you saw was white on black, which means that the white areas are where there is "uptake" of the radiopharmaceutical. If that is true, based on the locations you mention, most likely white dots are due to spurs (benign bony overgrowths, facet joint arthritis, etc.). ...Read more
Maybe not: Areas if increased uptake can be caused by a number of different things. Fractures can do this as well as arthritis (if near a joint), infection and yes cancer can do this also...But other bone lesions that are not considered malignant can also do this. This is why it is so important to see your doctor, who can put this information together with your history, symptoms and results from other tests. ...Read more
I had chemo for breast cancer and a bone scan indicated a spot on my clavicle. My br cancer is gone but not the spot on the clavicle. What is it?
Hard to answer: Without seeing the images its difficult to answer this question. Where in the clavicle (i.E mid vs at sternoclavicular joint), morphology of the lesion and correlation to cross sectional imaging like ct/mri are important in further delineating the possible etiology of the "spot" (increased uptake in radiology lingo). It's also important to mention if you had trauma to the area. Talk to your doc! ...Read more
Can enthesopathy (on bone scan) at the achilles' tendon insertion; indicate both an old allusion injury and "new" rejury in the same spot.
Yes and no: Bone scintigraphy is a very sensitive way to detect this type of enthesopathy. However, the lesion can be seen for several months and sometimes many years after the initial inflammation. It depends on several factors such as repeated trauma or overuse of the lower limbs. The intensity of radiotracer uptake may also vary. If it is mild, it is likely to be an "old" injury. Good luck. ...Read more
The hospital found a dark spot on my left lung, was too have a biopsy but they changed to a bone scan whitch I will have in a few days. Why.?
Bonds scan?: While I can see reasons were a bone scan might be useful, I would usually order a pet scan in such a situation. If your doctors are concerned for lung cancer, then they are looking for evidence that it has spread. If it has spread, then biopsy of the metastasis is more important than biopsy of the lung nodule. ...Read more
Painful spot on spine @ thoraco-lumbar junction. No radiating or deferred pain, or numbness. MRI & Bone Scan results normal. Myofascial trigger point?
I have a known bone tumor it was found in a MRI. .. I had a bone scan done and the tumor showed up HOT. .. does that mean it's malignant? Would a. Benign tumor ever show up hot in bone scan. .. everything I read online says benign would show up cold
Possibly: A bone scan is a very sensitive test but it is not very specific. It will simply "light up" anywhere there is increased bone activity. Fractures, infection, cancers, and benign bone processes can light up on a bone scan. Osteoid Osteoma and Paget's disease are just two examples of benign processes that can light up on a bone scan. Discuss with your doctor, if any question, may need biopsy. ...Read more
normal uptake: Bone scan involves intravenous injection of radiotracer 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 uptake is seen in metal artifacts, aggressive tumor/infection, & loss of blood supply to bones. No abnormal uptake in skeleton is normal. ...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
