1) Using the term "if clinically consistent or if clinically indicated"
2) Further evaluation is "advisable", advisable often gives an unsure interpretation of the findings, and creates the confusion whether added investigation is required or not. Ideal practise should have a note justifying your choice for the further investigation
3) Where "impression is as long as the findings description". Good report will have a long description with a brief impression.
4) Being judgemental like using the words "poorly aligned fracture"
5) Not comparing with previous films or not going through old films. Mammograms especially, cannot be read without comparison and error rates for people who dont compare are very high.
6) Not communicating urgent findings to the referring physician.
7) Never refusing a study even when you feel it is totally irrelevant. Debatable!
8) Not reading.
