A 42-year-old woman with subarachnoid and intracerebral hemorrhage was investigated with diagnostic angiography, disclosing an occlusion of the left internal carotid artery and the middle cerebral artery. CT examination immediately after the angiography revealed a 12-h-old infarct of the left middle cerebral artery territory. ⋯ Air had most probably been introduced during the angiography and had consequently been "trapped" in the cortical arteries of the ischemic brain. In the non-ischemic parts of the brain air may have passed through the vessels leaving no trace.

To determine the long-term outcome after fusion for adolescent idiopathic scoliosis in terms of degenerative disc findings diagnosed using MR imaging and to elucidate the clinical consequences. ⋯ There were significantly more degenerative disc changes (p<0.0001), disc height reduction (p=0.0010) and end-plate changes (p<0.0001 for both upper and lower end-plates) in the lowest unfused disc in the patient group compared with the control group. The MR findings in the lowest unfused disc, but not the one above, in the patient group correlated to lumbar pain intensity as well as to the diminished lumbar lordosis.

Comparative Study
Perfusion-related parameters in intravoxel incoherent motion MR imaging compared with CBV and CBF measured by dynamic susceptibility-contrast MR technique.
Perfusion-related parameters obtained by intravoxel incoherent motion (IVIM) MR imaging (MRI) were compared with cerebral blood volume and flow (CBV and CBF), retrieved by dynamic susceptibility-contrast (DSC) MRI. ⋯ The IVIM concept provided results that agreed reasonably with conventional CBV and CBF. The non-linear fitting to noisy signal data was problematic, in accordance with previously presented simulations.
