We have had a number of false positive studies in the lateral wall on our sestamibi SPECT studies. We are using a single head camera, patient supine and left arm up positioning. Floods and bars look good. Any ideas why this could be happening?

Things to consider:
1. Were the stress tests pharmacological or exercise?
2. The lateral wall seen on the raw data?
3. Was the lateral wall defect was seen on rest and stress images? were the ekgs correlate with the findings? was ekg normal during imaging?
4. Were the patients properly aligned to the camera? Is the same tech was imaging rest and stress images? Were the patients reimaged on prone imaging to see if the lateral wall visualized?
5. Any similiarites among the patients with lateral wall artifacts, for example, obese or certain body habitus, male or female, history of hiatal hernia?
6. is it from overprocessing the images?
7. are you an snmmi member, try the snmmi connect on their website, maybe you can find if other centers have similiar issues and what did they do to fix the issue
