[MRI in the early diagnosis of spinal metastases of bronchial cancer].
MRI of the whole spine and radionuclide bone scan were performed prospectively on 50 consecutive patients with newly diagnosed non small-cell lung carcinoma. The final diagnosis of vertebral metastasis was made by means of follow-up studies. The prevalence of vertebral metastasis was 24% (12/50 patients). The sensitivity of MR imaging (92%) was superior to that of radionuclide bone scan (67%) in the detection of vertebral involvement, the specificity was the same (94%). MRI of the spine was not useful as a screening procedure before treatment, but offered advantages over radionuclide bone scan in patients with symptoms and when bone scintigraphy detected abnormal foci, including identification of additional vertebral metastatic foci and better analysis of the extent of metastatic involvement within vertebrae.
