  • PICA
  • The mean visual score by MBIR was 3.0 or higher for all those arteries except the AICA assessed by reader 1 (2.6 ± 0.7).CONCLUSIONS:With 3D brain CTA, contrast-to-noise ratio and arterial delineation of the VA, SCA, AICA, and PICA in the posterior fossa are better with MBIR than FBP.

  • lesion
  • Preoperative imaging demonstrated a 2.1-cm intradural lesion abutting the pons and basilar artery and extending through the dura mater.A gross total resection was successfully achieved endoscopically without neurovascular compromise or additional complications. (stanford.edu)
  • cistern
  • B , T1-weighted image shows the patent herniated basilar artery within the sphenoid sinus and a small amount of hyperintense subarachnoid hemorrhage in the prepontine cistern ( arrowhead ). (ajnr.org)
  • basal
  • The vertebral and internal carotid arteries are visible as they reach the basal surface of the brain to enter into the formation of the arterial circle of Willis. (stanford.edu)
  • vessel
  • Increased PComA vessel luminal size is directly proportional to improved patient outcome after basilar artery and first segmental PCA occlusions [ 15 ]. (hindawi.com)
  • outcome
  • OBJECTIVES: To describe clinical, radiological findings, and outcome in a multiethnic population of stroke survivors with basilar artery occlusive disease (BAOC). (biomedsearch.com)
  • region
  • B , CT section at soft tissue window setting demonstrates hemorrhage in the sphenoid sinus, with a small hypoattenuated region posteromedially representing the patent basilar artery. (ajnr.org)
