Quick Answer: What Do Dark Spots On Bone Scan Mean?

Why would my dr order a bone scan?

Your doctor may order a bone scan if you have unexplained skeletal pain, a bone infection or a bone injury that can’t be seen on a standard X-ray.

A bone scan can also be an important tool for detecting cancer that has spread (metastasized) to the bone from the tumor’s original location, such as the breast or prostate..

Can degenerative disc disease cause neuropathy?

Answer: Yes—in some severe cases, degenerative disc disease (DDD) can cause nerve problems in the feet. Degenerative disc disease, specifically of the lumbar spine, can actually cause nerve pain to radiate into the feet from your spine.

Is a bone lesion a tumor?

Causes of bone lesions include infections, fractures, or tumors. When cells within the bone start to divide uncontrollably, they are sometimes called bone tumors. Most bone lesions are benign, meaning they are not cancerous. Some bone lesions are cancerous, however, and these are known as malignant bone tumors.

What does a cold spot on a bone scan mean?

Areas that absorb little or no amount of tracer appear as dark or “cold” spots. This could show a lack of blood supply to the bone or certain types of cancer. Areas of fast bone growth or repair absorb more tracer and show up as bright or “hot” spots in the pictures.

Does a bone scan show inflammation?

Bone scan is one of the most common and oldest examinations among all nuclear medicine procedures. It is used in the evaluation of benign bone disease like infection/inflammation and also is the standard of care for evaluating metastatic disease in the breast, prostate, and lung cancer.

Is a bone scan the same as an MRI?

A bone scan is just one imaging tool used to identify bone conditions in an individual. MRIs are also effective in producing internal images of the body that can be used to make proper diagnoses.

Are bone biopsies painful?

Summary. A bone marrow biopsy is a quick procedure that doctors use to extract and examine a bone marrow sample. This sample can help them diagnose a range of blood diseases, including certain cancers. The procedure often causes pain, but this pain is manageable in the correct medically guided way.

What is the difference between a bone scan and a CT scan?

CT scans of the bones can provide more detailed information about the bone tissue and bone structure than standard X-rays of the bone, thus providing more information related to injuries and/or diseases of the bone.

What does a spot on a bone scan mean?

The areas where the radionuclide collects are called “hot spots,” and may indicate the presence of conditions such as arthritis , malignant (cancerous) bone tumors , metastatic bone cancer (cancer which has spread from another site, such as the lungs), bone infections , bone trauma not seen on ordinary X-rays, and …

Will a bone scan show disc problems?

Making a degenerative disc disease diagnosis can require additional tests. Bone scan: To help your surgeon detect spinal problems such as osteoarthritis, fractures, or infections (which can all be related to DDD), you may have a bone scan.

Does a bone scan show arthritis?

Many changes that show up on a bone scan are not cancer. With arthritis, the radioactive material tends to show up on the bone surfaces of joints, not inside the bone. But it can be hard to tell the difference between arthritis and cancer — especially in the spine.

How do I read my bone scan results?

Understanding Bone Density Test ResultsA T-score of -1.0 or above is normal bone density. Examples are 0.9, 0 and -0.9.A T-score between -1.0 and -2.5 means you have low bone density or osteopenia. … A T-score of -2.5 or below is a diagnosis of osteoporosis. … The lower a person’s T-score, the lower the bone density.

What are the side effects of radioactive dye?

RisksAllergic reaction. Though rare, you could be allergic to the radioactive dye that’s injected during a nuclear stress test.Abnormal heart rhythms (arrhythmias). … Heart attack (myocardial infarction). … Dizziness or chest pain. … Low blood pressure.

How long does it take to get the results of a bone scan?

A radiologist will interpret the images, write a report, and deliver the results to your doctor via the internal computer system. This process usually takes less than 24 hours.

What type of machine is used for a bone scan?

The special camera and imaging techniques used in nuclear medicine include the gamma camera and single-photon emission-computed tomography (SPECT). The gamma camera, also called a scintillation camera, detects radioactive energy that is emitted from the patient’s body and converts it into an image.

What does bone turnover mean?

Bone turnover is the process of resorption followed by replacement by new bone with little change in shape, and it occurs throughout a person’s life. … Osteoblasts are mature bone cells responsible for bone formation and ossification.

What does increased activity in bone scan mean?

Other possible mechanisms of increased activity on bone scans include increased blood flow, increased mineralisation of osteoid and interrupted sympathetic nerve supply.

Can you eat before a bone scan?

Preparing for a Nuclear Bone Scan You can eat and drink as you usually would before your scan. You don’t have to do anything special to prepare. But certain things can interfere with the tracer, so tell your doctor if you have: Taken an over-the-counter medication containing bismuth (such as Pepto-Bismol)

What do black spots on bone scan mean?

Radionuclide bone scans Bone scans also can show how much damage the cancer has caused in the bone. Areas of diseased bone will be seen on the bone scan as dense, gray to black areas, called “hot spots.” These areas suggest cancer is present, but arthritis, infection, or other bone diseases can also cause hot spots.

What does an abnormal bone scan look like?

Results are considered abnormal when the scan shows darker “hot spots” or lighter “cold spots” in the bones. Hot spots describe places where an excess of radioactive substance has collected. Cold spots, on the other hand, are areas where it didn’t collect at all.

Can a bone scan detect osteoporosis?

A bone density scan can detect thinning bones at an early stage. If you already have osteoporosis, bone scans can also tell you how fast the disease is progressing. But an abnormal bone scan can create as many questions as it answers.
