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).
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.
DXA is only able to provide the areal bone mineral density. High-resolution peripheral quantitative computed tomography (HR-pQCT) is better than DXA at detecting bone microarchitecture, modeling whole-bone geometry using 3-dimensional information from scans. This method allows estimation of bone strength and other mechanical properties. [20]

The lesion may arise de novo or may arise secondarily within a pre-existing bone tumor, because the abnormal bone causes changes in hemodynamics. An aneurysmal bone cyst can arise from a pre-existing chondroblastoma, a chondromyxoid fibroma, an osteoblastoma, a giant cell tumor, or fibrous dysplasia. A giant cell tumor is the most common cause ...
Unicameral bone cysts can be classified into two categories: active and latent. [4] An active cyst is adjacent to the epiphyseal plate and tends to grow until it fills the entire diaphysis , the shaft, of the bone; depending on the invasiveness of the cyst, it can cause a pathological fracture or even destroy the epiphyseal plate leading to the ...
The operator then uses an ultrasound probe to examine the baby's brain, viewing the images on a computer screen and recording them as necessary. [ citation needed ] A standard cranial ultrasound examination usually involves recording of approximately 11 views of the brain from different angles, six in the coronal plane and five in the sagittal ...
