This is an article from the radiology literature that essentially tries to say that CT is not the imaging modality of choice for upper abdominal pain.<\/p>\n
It’s a retrospective review of 235 patients over a four-year period who had CTs of the abdomen reported as “normal” or “non-diagnostic” in the setting of upper abdominal pain. They determine false-negative studies if another diagnostic modality eventually provided a definitive diagnosis for the patient’s symptoms. Out of the 235, 81 were lost to follow-up and 27 were excluded for other reasons. Of the remaining 127, 46 were classified as false-negative and 81 were classified as true-negative.<\/p>\n
The misses? 23 cases of pancreaticobiliary disease (biliary colic, cholecystitis, choledocholithiasis), 12 cases of gastritis\/gastric ulcer disease, and 6 miscellaneous cases that included Mediterranean fever and prosthetic valve endocarditis.<\/p>\n
So, yes, there is some inkling that CT of the upper abdomen is going to miss a segment of pathology. On the other hand, this paper presents incomplete data regarding the true positives and false positives – making evaluation of this specific imaging indication incomplete other than to remind clinicians that the evaluation may need to continue in the setting of a negative CT.<\/p>\n
“Negative predictive value of intravenous contrast-enhanced CT of the abdomen for patients presenting to the emergency department with undifferentiated upper abdominal pain” This is an article from the radiology literature that essentially tries to say that CT is not the imaging modality of choice for upper abdominal pain.
