The term “is evidence of...” should only be used for findings which are inferred and not directly observed. E.g., “No evidence of portal venous hypertension”. Conversely, it is inappropriate to say “no evidence of pleural effusion”, since the phrase “no pleural effusion” is preferable.
Avoid the adjective “significant”. E.g., “No significant adenopathy” – does this mean there is insignificant adenopathy?
Use the active rather than the passive tense. E.g., “The pancreatic head mass obstructs the common bile duct”, rather than “The pancreatic head masses causes obstruction of the common bile duct”.
The phrase “cannot be excluded” should be avoided as far as possible; it is a grammatically undesirable double negative, and is used differently by radiologists. E.g., stating “spiculated 4 cm lung mass, bronchogenic carcinomas cannot be excluded” when the actual intended meaning is “spiculated 4 cm lung mass, bronchogenic carcinoma is likely”. When a diagnosis is mentioned, but considered unlikely, other options are to state “x is a remote possibility/consideration” – this expresses the intended meaning without using an unwieldy double negative.
