Since stress injection images performed first there is radio nuclide decay seen over the heart on rest imaging here.

If rest images done first and there was infiltration of radio nuclide, there would have been no cardiac uptake and even more photon deprivation artifact.

Since stress test results were showing no ischemia or infarct. We did not repeat the rest imaging.

We were able to review the stress gated imaging adequately.

Another thing to keep in mind when there is an inpatient with multiple IV lines the technologist must be aware of the mechanisms of using T shaped valves and turning in the correct direction while injecting and using the flush adequately. Not to inject into long IV lines and inject as close to vein as possible to avoid injection related fallacies and artifacts.
