Abstract
To assess prospective accuracy and clarify indications for diagnostic study, 45 patients suspected clinically of having pancreatic disease were studied by conventional barium examination of the upper gastrointestinal tract, hypotonic duodenography, selective angiography and selenomethionine isotope scanning. Duodenography achieved 78 per cent, isotope scanning 72 per cent, conventional upper gastrointestinal examination 57 per cent, and angiography 55 per cent correct prospective diagnoses. Isotope scanning produced most (19 per cent) false-positive and angiography most (38 per cent) false-negative interpretations (most of those falsely negative on angiography occurred in patients with pancreatitis).
