MCQ : Nuclear-01
52 year old male with hypercholesterolemia and dyspnea on exertion. he was submitted o a stress/rest SPECT with regadenoson.
What is the best interpretation of these images?
1 – LAD Ischemia
2 – LCX ischemia
3 – LAD and LCX ischemia
4 – Three vessels ischemia


Right answer is: Ischemia in three territories
In the stress images, there is a moderate defect involving: anterior wall (medium and distal portion, antero-lateral wall (medium and distal portion), inferior wall (proximal portion).
In the rest images, there is a homogeneous perfusion in the whole ventricle.
The dynamic acquisition, obtained by CZT camera, allows the quantitation of the absolute MBF: the absolute values, as well as the CFR indicates an impaired CFR in the three territories
