Findings negative for cardiac amyloidosis by NM imaging criteria.
Thoracic scan in the anterior view performed 1 hour after administration of 99m-technetium pyrophosphate.
Semi quantitative cardiac Perugini grading scale is 0.
There is no intense radiotracer accumulation in the myocardium. Region of interest markers placed over the myocardium and contralateral right lung for quantification of radiotracer activity. The total counts within the myocardial region of interest divided by the contralateral counts were used to calculate the heart-to-contralateral ratio.
Ratio is > 1.5 is abnormal.
Here it is < 1.5. So normal.
