Monitoring of bone scintigraphy with bone transplantation
Shape, and can reflect the local blood supply and metabolic bone conditions .... Is to determine the efficacy of graft survival and a better way. Data and Methods, study after flap with vascularized iliac bone graft transverse process of the sacrum in patients with 5 feeding, feeding women l men and 4 feed; respectively after 2 weeks and 3 to 4 months after the nuclear tangled bone scintigraphy. Second, the imaging method uses the U.S. production Ⅱ EsYs300o type SpF ~ 'T-a three-phase dynamic bone scintigraphy. Lying by the person picking up the probe aligned lumbosacral view, the elbow vein lumbosacral blood flow and blood pool phase-phase dynamic imaging, the matrix is too small 64 × 64; underwent the same site in 3 hours delayed static imaging, matrix size 256 × 256, were collected l5OOK count. The same rectangular region of interest analysis using the computer program calculated the corresponding area contralateral graft area and the time radioactivity curve and the ratio of radioactive counts. Third, the results of graft survival with metabolic activity, showed radioactivity brigade set; graft survival is not the amount of radioactive concentration is very low, or is not trip set. This 5 patients 2 weeks and 3 to 4 months after bone graft in the area in the normal bone tissue were significantly similar to the radioactive brigade set, bone area and corresponding contralateral areas were significantly higher radioactive count, time radioactivity curve graft area showed good blood flow. The image can be seen after 2 weeks. Bone area blood flow and blood pool phase, the phase distribution of radioactive zone was significantly higher than the corresponding contralateral uptake; delayed the distribution of radioactive bone area than the contralateral area and the surrounding bone tissue was significantly journey together, show a clear form of bone flap. 3 to 4 months after bone graft area, see the map imaging blood flow and blood pool phase relative to the radioactive distribution and no significant contralateral corresponding area of the unit: 230001 Hefei, Anhui Provincial Hospital DOCTOR subject 61P7,;} {hesitant dispute between sea turtle, still delayed contralateral corresponding area of radioactive trip distribution set, but similar to the surrounding bone tissue. 2 weeks after X-ray examination is difficult to identify bone flap, 3 to 4 months after x-ray see the phenomenon of bone fusion graft area. Early understanding of the discussion after transplantation of bone graft bone and osteogenic activity of the blood supply is very useful, in the x-ray examination is difficult because of early assessment of bone mineral density did not change significantly the success of bone graft. Nuclear tangled radionuclide bone imaging is marked on the Bo orderly (phosphine) compounds, the role of salts as imaging agents, which can be bone inorganic (hydroxyapatite) adsorption, and mainly within the immature collagen and bone combined, and can be compounds containing phosphoric acid tissue uptake. Whatever the result of orderly activity of osteoblasts, to accelerate new bone formation, may therefore lead to increased uptake of imaging agent, radionuclide bone imaging in the distribution of tangled bones can indirectly reflect the local blood supply,[link widoczny dla zalogowanych], bone metabolism and regeneration [ ,],[Even the early changes in bone imaging can also be accurately detected. Our results show that 2 weeks after transplantation of bone orderly nuclear bone scan to see significant bone uptake in area,[link widoczny dla zalogowanych], and delayed phase significant radioactive bone flap trip together, reflecting the rich blood supply transplantation. Active bone formation, while the x-ray before 3 months after surgery showed obvious bone to change this with the reported results consistent with J,[link widoczny dla zalogowanych], that edge can be more orderly bone scan earlier on x ray imaging bone graft survival and to make correct evaluation of clinical practical value
