Spinal tuberculosis is curable disease, and early diagnosis is mandatory for early treatment . We reviewed conventional radiographies and computed tomograms(CT) from Histopathologically confirmed 30 cases of spinal tuberculosis, and compared these findings with raidiologic findings from 2 cases of pyogenic spondylitis and 4 cases of metastasis. The results were as follows : 1. The frequent site of involvement were thoracolumbar junction and low lumbar vertebrae, and the most frequent type is multisegmented subligamentous type(93.3%). 2. CT was not of great use in the differential diagnosis of the tuberculosis. Dominant CT findings of tuberculous spondylitis were anterior vertebral body destruction , paravertebral soft-tissue mass and thick walled abscess formation occasionally containing calcification and disc space narrowing in the setting of an indolent or relatively benign course. 3. CT is the best modality for imaging the extent and anatomy of the destructive process, the egree of canal encroachment, and the change of adjacent vital structures. So CT was particularily useful in pre-operative planning of debridement and stabilizaton surgery. 4. The most common causes of neurologic manifestations in tuberculous spondylitis were the compressin of spinal cord by sequestrated bony fragments and disc material , granulation tissue or abscess in the spinal canal.

Cytogenetic effects of radiation exposure and ionic contrast media were evaluated in peripheral lymphocytes. Accentric chromosome fragments produced n cells by radiation exposure or othe agents give rise to imcronuclei in daughter cells. The micronuclei could be counted readily in larger number of cell which provided a sensitive measure of radiation exposure and contrast media induced chromosome aberration. Radiation exposure and contrast media induced microunclei formations in human lymphocytes were counted in vitro and in vivo. Results were as follows: 1. Micronuclei in lymphocytes were produced by exposure to contrast media and/or radiation. 2. Numbers of micronuclei formation in peripheral lymphocytes after enhanced CT were more increased than inert condition. 3. Lymphocytes of micronuclei formation were increased in number of the plate prepared with contrast media only, but the number of lymphocyte of microniclei formation was not proportional to the concentration of contrast media. 4. The number of lymphocytes of radiation exposure and contrast media induced micronuclei formation was increased than te preparation with contrast media only. 5. The number of lymphocyte of radiation exposure and contrast media induced micronuclei formation in vitro was more increased than enhanced CT in vivo.
