Abstract
The following questions for SVU-CME examination are based on the article entitled “Cerebral Blood Flow Volume in Posterior Circulation Ischemic Disorders.”
Both true/false and multiple-choice questions are included. There is only one (1) correct answer for the multiple-choice test items. Answer all the questions as listed below. One-half (1/2) CME credit will be awarded for successful completion of this test with a grade of 80% or more.
Which of the following imaging modalities was the principal method used in this study to assess blood flow volume in the posterior circulation? Computed tomography angiography Color-duplex ultrasound Magnetic resonance imaging Positron emission tomography
In comparing patients with vertebrobasilar insufficiency and healthy volunteers, no significant differences were found in measurements of:
Blood flow volume in each of the internal carotid arteries Aggregated blood flow volume in the internal carotid arteries Aggregated blood flow volume in the vertebral arteries Total blood flow volume to the brain
For patients with posterior circulation ischemic stroke, a decrease in blood flow volume in the posterior circulation was associated with the presence of steno-occlusive disease.
True False
Which artery was affected significantly more often with steno-occlusive disease in patients with posterior circulation ischemic stroke?
Basilar artery Left vertebral artery Right vertebral artery Ophthalmic artery
There was no significant difference between the aggregated blood flow volume in the internal carotid arteries in the younger and older subgroups of healthy volunteers.
True False
Aggregated blood flow volume in the vertebral arteries did not vary significantly with age. True False
Instructions: CME tests are offered only online at www.svu.org. SVU Members can complete the tests and earn CME for free. Nonmembers will be charged $20 per one-half (1/2) CME test taken. All exams for SVU CME must be completed by November 30, 2024.
