静脉注射 33mTc-MDP 20 mCi，4 小时后行前位、后位全身

Intravenous injection of 33mTc-MDP 20 mCi, anterior and posterior whole-body bone imaging 4 hours later, + SPECT/CT tomographic imaging: the <br>whole body bone collection is complete, the drug is well marked, the image is clear, the ribs are arranged neatly, and the skull is visible in the posterior position Localized nuclide concentration, higher strength than adjacent bone, clear boundary, uniform nuclide distribution; localized nuclide concentration, less uniform nuclide distribution, and less clear boundary can be seen in the L3-5 vertebral body. <br>The remaining bones and joints showed no obvious abnormalities. <br>SPECT/CT tomographic imaging: L3-5 vertebral bodies can be seen with enhanced heterogeneous nuclide distribution, and CT with corresponding parts can be seen with enhanced heterogeneity.

Intravenous injection of 33mTc MDP 20 mCi, followed by anterior and posterior whole body bone imaging and SPECT/CT tomography after 4 hours:<br>Whole body bone collection is complete, drug labeling is good, images are clear, ribs are arranged neatly, localized nuclide concentration can be seen in the posterior position of the skull, with higher intensity than adjacent bones, clear boundaries, and even distribution of nuclides; Localized nuclide concentration can be observed in the L3-5 vertebral body, with uneven distribution of nuclides and unclear boundaries.<br>No obvious abnormalities were found in the bones and joints imaged by the remaining organs.<br>SPECT/CT tomography: local nuclide inhomogeneity distribution enhancement can be seen in L3-5 vertebral body, and inhomogeneity enhancement can be seen in corresponding CT.

Intravenous injection of 33mTc-MDP 20 mCi, 4 hours later, anterior and posterior whole body bone imaging,+SPECT/CT tomography:<br> Whole-body bone collection is complete, drug labeling is good, images are clear, ribs are arranged neatly, localized nuclide concentration can be seen at the back of skull, the intensity is higher than that of adjacent bones, the boundary is clear, and the nuclide distribution is even; In L3-5 vertebral body, localized nuclide concentration, uneven nuclide distribution and poor boundary can be seen.<br> No obvious abnormality was found in the other bones and joints.<br> SPECT/CT tomographic imaging: L3-5 vertebral body can be seen with enhanced heterogeneous distribution of localized nuclides, and the corresponding parts can be seen with enhanced heterogeneous CT.
