To determine whether the signal changes on magnetic resonance imaging (MRI), including fluid attenuated inversion recovery (FLAIR), T2*-weighted gradient echo (GE) imaging, and diffusion-weighted imaging (DWI) in diffuse axonal injury (DAI) patients correlate with the clinical outcome. ⋯ DWI cannot detect all DAI-related lesions, but is a potentially useful imaging modality for both diagnosing and assessing patients with DAI.

To evaluate the success of a new guidance device for sacroiliac joint puncture. ⋯ The new guidance device makes sacroiliac joint injection easier and prevents unnecessary exposure to radiation during the procedure.

Case Reports
Magnetic resonance imaging and diffusion tensor analysis of lymphomatoid granulomatosis of the brain.
We present the case of a 56-year-old man suffering from acquired immune deficiency syndrome associated with lymphomatoid granulomatosis. Magnetic resonance imaging performed because of convulsions revealed an ill-defined frontal mass showing hypointense on T1WI and slightly hypointense on T2WI with surrounding edema. ⋯ However, the apparent diffusion coefficient ratio calculated from diffusion-tensor acquisitions was 1.53 and was higher than that of lymphomas in previous reports. Stereotactic brain biopsy was performed and lymphomatoid granulomatosis was confirmed.

A 23-year-old woman was transferred to our department with loss of consciousness 6 h after undergoing rod placement for thoracolumbar scoliosis. Both computed tomography and magnetic resonance imaging of the brain revealed diffuse pneumocephalus and infra- and supratentorial hemorrhages. ⋯ The patient was re-operated and the dural tear was repaired. To our knowledge, this is the first description of these uncommon complications in one patient after spine surgery.
