In this work 99mTc-MIBI cardiac scintigraphs are quantitively analyzed with the aim to determine the radiopharmaceutical uptake in the heart (organ of interest) and in the liver. The impact of the radioactivity distribution in the diagnostic quality of the images is discussed.

This work analyzes the reliability of the radiochemical purity control method of99mTc-MIBI used in nuclear medicine services and the influence of the greater presence of radiochemical impurities in the diagnostic quality of the obtained images.
