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). [1]
The intercondylar fossa of femur (intercondyloid fossa of femur, intercondylar notch of femur) is a deep notch between the rear surfaces of the medial and lateral epicondyle of the femur, two protrusions on the distal end of the femur (thigh bone) that joins the knee.
The standard set of X-rays for a skeletal survey includes X-rays of the skull, entire spine, pelvis, ribs, both humeri and femora (proximal long bones). It is more effective than isotope scans at detecting bone involvement in multiple myeloma. Although significantly less sensitive than MRI, it is easier to include more bones. A study found that ...
REMS processes the raw, unfiltered ultrasound signals acquired during an echographic scan of the axial sites, femur and spine. The analysis is performed in the frequency domain. Bone mineral density is estimated by comparing the results against reference models. The accuracy has been tested by comparing it against to DXA technology. [1] [2] [3] [4]
Teenagers who are active in sports often complain of pain in the lower femur, or immediately below the knee. If the tumor is large, it can present as overt localised swelling. Sometimes a sudden fracture is the first symptom because the affected bone is not as strong as normal bone and may fracture abnormally with minor trauma. In cases of more ...
Schematic diagram of a conventional MRI scanner. Not shown are the electronic control systems and service plant (chillers, etc.) these are usually installed in a seperate room. 19:42, 6 January 2007: 2,980 × 4,213 (34 KB) ChumpusRex: Schematic diagram of a conventional MRI scanner.
The neck is flattened from before backward, contracted in the middle, and broader laterally than medially. The vertical diameter of the lateral half is increased by the obliquity of the lower edge, which slopes downward to join the body at the level of the lesser trochanter , so that it measures one-third more than the antero-posterior diameter.
DEXA assessment of bone mineral density of the femoral neck (A) and the lumbar spine (B): T scores of - 4.2 and - 4.3 were found at the hip (A) and lumbar spine (B), respectively in a 53-year-old male patient affected with Fabry disease. The World Health Organization has defined the following categories based on bone density in white women:
