Reversed mismatch on PET (Positron Emission Tomography) scan is seen in:<\/strong><\/span><\/p>\n

    \n
  1. Left bundle branch block<\/li>\n
  2. Right ventricular pacing<\/li>\n
  3. Non ischemic cardiomyopathy<\/li>\n
  4. All of the above<\/li>\n<\/ol>\n

    Correct answer: 4) All of the above<\/strong>
    \n‘Reversed mismatch’ means normal perfusion, with reduced uptake of 18-fluoro-deoxy-glucose (FDG).
    \nIn addition to the above conditions, this situation can also be seen in the setting of revascularization early after myocardial infarction and sometimes in diabetes mellitus.
    \nUsual perfusion-metabolism mismatch is reduced myocardial perfusion and contractile function in with\u00a0relatively preserved or increased FDG uptake. It may be noted that ischemic myocardium switches over to glucose utilization instead of the usual fatty acid metabolism as glucose metabolism gives more ATP (adenosine tri phosphate) per oxygen molecule used. Tracers used to assess perfusion during PET scan include rubidium 82 and N-13 ammonia.
