Though I am inclined to agree, and most of the times I see buzzwords I look for the 'gotcha' aspects of the question, radiology would be an exception. If they were to show you a bird's beak oesophagus and then call it scleroderma, that would be a poorly worded if not outright incorrect question stem. Radiology buzzwords are useful even today, unlike clinical buzzwords which oftentimes only describe the classical manifestation rather than the common manifestation of a condition.
