We evaluated the use of three-dimensional (spiral) computed tomography (CT) to assess widening of the bony cervical spinal canal following en bloc open-door C3-C7 laminoplasty in 31 patients. Measurements were performed using a computerised image processing system. The increment in the anteroposterior spinal canal axis and volume of the bony spinal canal(More)
BACKGROUND Epilepsy is the most common neurological disease in veterinary practice. However, contrary to human medicine, epilepsy classification in veterinary medicine had not been clearly defined until recently. A number of reports on canine epilepsy have been published, reflecting in part updated proposals from the human epilepsy organization, the(More)
A 12-year-old spayed female Labrador retriever was presented with forebrain signs. Brain MRI revealed a huge cystic lesion with the thickened falx in the frontal region. The brain parenchyma surrounding the lesion showed significant signs of a mass effect and also increased intracranial pressure. However, the dog suddenly became lucid after about two weeks,(More)
The purpose of this study was to compare short-TE-long-TR images with T1-weighted images in knee MR examinations. Sagittal MR images of the knee were obtained in 31 patients with knee pain. T1-weighted images were obtained by the spin-echo technique (TR/TE = 350/15), and short-TE-long-TR images by fast spin-echo (TR/TE = 1300/15) with an echo-train length(More)
FLAIR (fluid-attenuated inversion recovery) images are MR images obtained with an inversion recovery sequence having a long inversion time (TI) and a long echo time (TE). We examined 47 cases (56 graphics) of lacunar infarction (LI), 28 cases (32 graphics) of cortical infarction (CI) and 16 cases (23 graphics) of stem infarction (SI) with a FLAIR sequence(More)
FLAIR (fluid-attenuated inversion recovery) images are MR images obtained with an inversion recovery sequence, which has a long inversion time (TI) and a long echo time (TE). We examined 29 cases (49 graphics) of cerebral contusion, 11 cases (22 graphics) of diffuse axonal injury (DAI) and 11 cases (11 graphics) of traumatic subarachnoid hemorrhage (t-SAH)(More)
A case of ruptured distal anterior cerebral artery aneurysm presenting with diagnostic dyspraxia is presented. A 54-year-old female was referred to our hospital with the complaint of sudden onset of headache followed by disturbance of consciousness. CT and MRI revealed subarachnoid hemorrhage with hematomas in the interhemispheric fissure and the(More)
