A bone scan or bone scintigraphy / s ɪ n ˈ t ɪ ɡ r ə f i / is a nuclear medicine imaging technique used to help diagnose and assess different bone diseases. These include cancer of the bone or metastasis, location of bone inflammation and fractures (that may not be visible in traditional X-ray images), and bone infection (osteomyelitis).
English: 3D rendered CT scan of bone metastases of the hip bone, in a 60 year old woman with parotid gland cancer. Large lesions are seen on the ilum on the more distant side. Involvement of the vertebral column has caused a compression fracture.
Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1] It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), [2] but is able to provide true 3D information. This information is typically ...
Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones. Bone-originating primary tumors such as osteosarcoma, chondrosarcoma, and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [1] Bone metastases can be classified as osteolytic, osteoblastic ...
Bone cancer: bone metastases located in the spine, pelvis and long bones can be treated with image-guided ablative techniques (RFA, MWA, cryoablation, electrocorporation) with or without injection of cement (cementoplasty) to stabilize the bone. These treatments may be palliatively for bone metastases pain, or for some cases such as osteoid ...
The study is particularly helpful in differentiating conditions such as osteomyelitis from decubitus ulcers for assessment of route and duration of antibiotic therapy. [1] [2] In imaging of infections, the gallium scan has a sensitivity advantage over the indium white blood cell scan in imaging osteomyelitis (bone infection [3]) of the spine ...
A skeletal survey (also called a bone survey [1]) is a series of X-rays of all the bones in the body, or at least the axial skeleton and the large cortical bones. A very common use is the diagnosis of multiple myeloma , where tumour deposits appear as "punched-out" lesions.
The trabecular bone has much higher metabolic activity than the cortical bone and so is affected by age, disease and therapy-related changes earlier and to a greater degree than cortical bone. This means that QCT of the spine has an advantage compared to other bone density tests because earlier changes in bone mineral density may be detected .
