Cognitive Biases, Heuristics and error in Radiology

Interested attached article.
I believe a heuristic or a mental shortcut is extremely valuable in diagnosis as long as we recognize it is a method of discovery, not as a method of evidence. It merely makes us suspect a disease, not confirm a disease. In the example of enlarged pancreatic head seen by a radiologist, the correct approach would be, in my view, to suspect pancreatic carcinoma based on the heuristic of resemblance, not diagnose it definitively which can be only be done after a biopsy. Perhaps a differential diagnosis listing pancreatic carcinoma, autoimmune pancreatitis and any other pancreatic diseases would be the right way to report this finding.
I attach 3 papers regarding heuristics that I posted on Listserv in the last few months that have a bearing on the issue being discussed.
Thanks.

Hi Everybody -

I thought there might be interest in this brief article in the Rad Business Journal, which cites the attached peer-reviewed article-in-press, which is actually from next month's AJR:
