9 patients with 85 spinal lesions were evaluated. 1 patient had colon cancer, 2 patients had hepatocellular carcinoma, 2 patients had non small cell lung cancer, 2 patients had breast cancer, 1 had bladder cancer and 1 had poorly differentiated adenocarcinoma
In terms of conspicuity on diffusion weighted imaging compared to conventional imaging: 23/85 were deemed similar or unchanged, 40/85 were more conspicuous on the diffusion sequence and 16/85 were more conspicuous on conventional sequences.
In addition, 6 lesions that were identified on the DWI sequence were intitially missed on conventional sequence evaluation.
In terms of confidence in diagnosing lesions - 26/85 lesions that were deemed probably metastasis (score of 3) on conventional sequences were upstaged to definitely a metastasis (score of 4) by reviewing the DWI sequence. 7 lesions that were deemed equivocal (2) were upgraded to confident (4). 4 lesions that were deemed equivocal (2) were not seen on DWI and presumed to be benign (score of 1).
