Early diagnosis of disk space infection with 67Ga in an experimental model

Both 67Ga and 99mTc scans become positive in experimental disk space infection, but 67Ga does so earlier than 99mTc. The radiologic features of experimental disk infection are similar to those seen clinically. Disk infection commences primarily in the disk and not in the vertebral body. Gallium-67 is useful in diagnosis of the disease under circumstances when the diagnosis is in doubt.
