[Quantitative evaluation of the suitability of magnetic resonance sequences for the detection of spinal bone marrow metastases of solid tumors].
OBJECTIVE
To compare MR sequences for the examination of the bone marrow of the spine in the detection of skeletal metastases.


METHODS
20 standardised prospective studies of the cervical, thoracic or lumbar spine in patients with known skeletal metastases were evaluated quantitatively. Studies included T1w SE with and without intravenous contrast medium (CM) administration of Gd-DTPA, T2w TSE with and without frequence selective fat saturation (SPIR), opposed phase gradient echo (opGE) with and without intravenous CM administration of Gd-DTPA and T1w SE CM SPIR sequences. The quantitative parameters signal/noise ratio (SNR), contrast/noise ratio (CNR) and contrast were evaluated.


RESULTS
OpGE with contrast showed the best results in SNR, CNR and C. Results were statistically significant. Good SNR and C also was found for T1w SE native. SPIR and T2w sequences were less sensitive.


CONCLUSIONS
OpGE sequences are recommended for the detection of skeletal metastases of the spine.
