  • The anterior cerebellar artery distribution and the contralateral side of the body
  • The middle cerebral artery distribution and the contralateral side of the body Answer - The middle cerebral artery distribution and the contralateral side of the body
  1. The most prevalent type of stroke is
  • Aneurysmal
  • Hemorrhagic
  • Septic embolic
  • Venous thrombotic
  • Ischemic Answer - Ischemic
  1. Among the chief limitations of continuous-wave Doppler is (are)
  • Depth information is not possible; precise location of flow pattern cannot be determined
  • The sample volume is too small to interrogate deeper vessels Answer - Depth information is not possible; precise location of flow pattern cannot be determined
  1. Which of the following determinants dictate(s) transducer frequency selec- tion for optimal carotid B-mode imaging?
  • Desired beam width
  • The average and extreme depths of carotid vessels in most subjects to be studied
  • Desired axial resolution
  • Cost
  • A, B, and C Answer - A, B, and C
  1. The term hemiparesis means
  • Paralysis of one side
  • Weakness of one side
  • Numbness/tingling on one side
  • Spasm of voluntary muscle on one side
  • Dizziness Answer - Weakness of one side

  • Resolves within 72 hours
  • Resolves after 24 hours
  • Resolves in one week Answer - Resolves within 24 hours
  1. To optimize carotid vessel image data, lateral resolution should be
  • As small as possible, to differentiate calcified lesions from fresh thrombus
  • As small as possible, to resolve side-by-side lesions
