  1. 1.
    Anatomic and functional cardiovascular magnetic resonance imaging (CMR) requires:
    1. A.

      Ability to perform long breath-holds (>15 s)

       
    2. B.

      Weight <100 kg (220 lbs)

       
    3. C.

      Sinus rhythm

       
    4. D.

      Absence of coronary stents

       
    5. E.

      Claustrophobia management

       

    Correct answer is E.

    CMR imaging no longer requires prolonged breath holding [1]. Patients of up to 230 kg (400 lb) may be imaged, although image quality may be suboptimal in the morbidly obese [2]. The presence of regular sinus rhythm is desirable for cardiac imaging but not mandatory. Stents cause local image artifacts but are not contraindication for CMR [3, 4, 5]. Claustrophobia management is essential before CMR is attempted.

     
  2. 2.
    In comparing CMR with other noninvasive imaging modalities, which of the following statements is correct?
    1. A.

      The exposure to ionizing radiation with CMR is more than with a single chest X-ray, but considerably less than that of a chest computed tomography (CT) scan

       
    2. B.

      The exposure to ionizing radiation with CMR...
