Bone scintiscanning in Orthopedics

diagnosis: stated earlier, bone scan is quite non specific and exceptions prove the rule. Regional pain that aggravates at Radionuclide imaging is perhaps the only means to image night in a young patient is quite typical of osteoid osteoma. the physiology of skeletal system. About 30% of mineral Osteoid osteoma and fibrous dysplasia are two entities loss must take place before an abnormality be...

Renal scintiscanning. A review.

Bone scintiscanning in osteolytic lesions.

Osteolytic lesions seen on plain radiographs can be caused by various disorders of the bones such as simple bone cyst, aneurysmal bone cyst, plasmacytoma, giant cell tumor, eosinophilic granuloma and tuberculosis. We studied prospectively Tc-99m-methylene diphosphonate bone scan findings in osteolytic lesions seen radiologically and followed them to histopathology. Interestingly, the scans in t...

Significance of increased "splenic uptake" on liver scintiscanning.

Peak activity over the spleen as a percentage of peak activity over the liver was measured in 265 (99m)Technetium sulphur colloid liver scintiscans. The value exceeded 70% in 50 cases. In 32 of these cirrhosis was present; the other 18 scans were from patients with a wide variety of conditions, including secondary deposits, hepatitis, and diseases involving the reticuloendothelial system. A mea...

Imaging of hepatic low density lipoprotein receptors by radionuclide scintiscanning in vivo.

The low density lipoprotein (LDL) receptor mediates the cellular uptake of plasma lipoproteins that are derived from very low density lipoproteins (VLDL). Most of the functional LDL receptors in the body are located in the liver. Here, we describe a radionuclide scintiscanning technique that permits the measurement of LDL receptors in the livers of intact rabbits. 123I-labeled VLDL were adminis...
