What does an abnormal bone scan mean?
Abnormal results can indicate that you have a bone disorder, such as cancer or arthritis or infection in the bone.
What does an abnormal bone scan look like?
An abnormal scan will show “hot spots” and/or “cold spots” as compared to surrounding bone. Hot spots are areas where there is an increased collection of the radioactive material. Cold spots are areas that have taken up less of the radioactive material.
Can a bone scan show infection?
Areas which take up more radiopharmaceutical show up as “hot” spots, indicating increased blood flow or bone turnover, and could point to problems like arthritis, a tumour, a fracture, or an infection. Depending on the area of concern, a bone scan can image the entire body or pay particular attention to certain parts.
What causes increased uptake on bone scan?
Thus, increased radiotracer uptake occurs with multiple pathologic processes such as fractures, infection, malignant disease and less commonly encountered osseous diseases like Paget disease, fibrous dysplasia, osteoid osteoma, and complex regional pain syndrome.
What does a positive bone scan mean?
Scan B shows numerous bone hot spots, a result of cancer that has spread to multiple locations. A bone scan might help determine the cause of unexplained bone pain. The test is sensitive to differences in bone metabolism, which are highlighted in the body by the radioactive tracer.
How does arthritis show up on a bone scan?
Areas of extra bone activity (common in both cancer and arthritis) will show up on the scan because the radioactive substance collects in areas of new bone formation. These areas appear as dark patches on the film.
Does a bone scan show arthritis?
Bone scans are used to detect arthritis, neoplasm, fractures and sports injuries, tumors and metastatic disease, as well as to evaluate unexplained bone pain.
How accurate are bone scans?
Results: The sensitivity, specificity, and accuracy for detecting skeletal metastatic disease of FDG PET/CT were 97%, 98%, and 98%, respectively, and of bone scan were 83%, 98%, and 93%, respectively. The lesions that bone scan most commonly missed were located in the pelvis, spine, and sacrum.
Can 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.
Will osteoarthritis show up on bone scan?
It was concluded from this study that bone scans may help to diagnose osteoarthritis when increased uptake ratios are observed.
Can a bone scan detect inflammation?
Does a bone scan show osteoporosis?
Bone density scans, also known as DEXA scans, help to work out your risk of breaking a bone. They’re often used to help diagnose bone-related health problems, such as osteoporosis, or to assess the risk of getting them.
Can a bone scan show arthritis?
Does a bone scan show tumors?
Bone scans are used primarily to detect the spread of metastatic cancer. Because cancer cells multiply rapidly, they will appear as a hot spot on a bone scan. This is due to the increased bone metabolism and bone repair in the area of the cancer cells.
Can you see arthritis on a bone scan?
What are the stages of osteoarthritis of the hip?
Stages of Osteoarthritis of the Hip Stage 1: Minor wear and tear of the hip joints and minor bone spurs, often with little to no pain. Stage 2: The cartilage begins to break down, and bone spur growths are often visible on X-rays. Symptoms include pain, discomfort and stiffness in the hip.
What does abnormal bone scan results mean?
Common diagnoses that stem from abnormal bone scan results include: osteoporosis, bone fractures, bone cancer, bone infection, arthritis, Paget’s disease (a bone disorder involving thickening and softening of bones) and avascular necrosis (death of bone due to lack of blood supply. [9]
Which radiographic findings are characteristic of atypical fractures of the femur?
A corresponding AP radiograph (2e) reveals similar periosteal and endosteal cortical thickening with intracortical transverse fracture lucency (arrow). Atypical fracture of the proximal left femoral shaft. Atypical femur fractures (AFFs) are the result of an uncommon stress reaction developing in the lateral cortex of the femoral shaft.
What are the common indications for a bone scan?
Table 1. Common indications for bone scan 1 Figure 2. A) Multiple skeletal metastases; B) Fibrous dysplasia of the right first rib When might a bone scan be positive when the X-ray is negative?
Can a bone scan show infection in the hip?
If the bone scan suggests infection, then a labelled white cell scan should be performed for confirmation. Infection may be excluded if the bone scan is suggestive but the white cell scan is negative (Figure 5). Figure 5. Increased activity associated with the hip prosthesis in (A) blood pool and (B) delayed phases.
