ABSTRACT

In conclusion, visualization of myocardial infarcts with ¹³¹Cs appears to be a promising method. Studies of the phantom heart have shown the following: (1) lesions can be well visualized if they are on the anterior wall, (2) attenuation from bony structures of the overlying chest wall has little effect upon scan quality if scan time is increased to maintain good statistics and (3) the use of low-energy collimators aids in obtaining scans of good quality. Although studies of the effects of respiration and cardiac contraction were not included in this experiment, it is felt that these factors would not significantly alter the scan image. The effect of biological distribution of ¹³¹Cs in the intercostal muscles was not determined. Further evaluation of the effectiveness of this radionucide will be pursued in future patient studies.
