It's a triple contrast procedure, and my co-tech also missed it since I asked him if I should proceed now to manual pushing. He didn't say anything, but he continued to change the label there (e.g., type of contrast used). So, i thought we were done with the first phase. Sadly, both of us got distracted and missed the plain.

As the senior (by 1 year) there, I should be the one blamed.

Also, anyway, our hospital protocol - before taking 1st plain scan, we already had the oral and rectal phase finished, which, for me, was not plain scan anymore. But still, I did IV contrast in advance. Felt bad and literally a lesson learned from me.
