ABSTRACT
PURPOSE:
To perform an activity-based cost analysis of the inclusion of contrast-enhanced ultrasound (CEUS) in the diagnostic pathway of newly detected focal pancreatic lesions revealed by abdominal ultrasound (US) in comparison to computed tomography (CT) and magnetic resonance imaging (MRI). MATERIALS ANDMETHODS:
Over a 14-year period, 977 patients with newly detected focal pancreatic lesions on US and subsequently studied with CEUS and/or CT and MRI were included. The cost of equipment, materials and human resources for every imaging method was calculated. We analyzed the costs in different scenarios considering whether or not CT or MRI was required in the diagnostic pathway. The savings (R) were calculated by subtracting the differential cost of CEUS from the eliminated third-level exam (CCEUS CEUS cost; CCT CT cost; CMRI MRI cost) compared to conventional ultrasound (CCEUS-CUS) Râ=âCCT-(CCEUS-CUS) or Râ=âCMRI-(CCEUS-CUS).RESULTS:
Total costs were US 28.39â; CEUS 70.50â; CT 106.23â; MRI 219.61â. In 388/563 patients CEUS characterized the pancreatic lesion as solid, with only CT being performed as a second-level investigation the savings were 68â870.36â. In 266/414 patients CEUS diagnosed lesions as cystic, with only MRI being performed as a second-level examination the savings were 16â825.07â. Considering the whole diagnostic pathway of the patients, the cost savings were 76â809.35â for solid lesions and 26â242.49â for cystic lesions, with overall savings of 103â051.84â.CONCLUSION:
CEUS represents a cost-effective imaging method for the differentiation of focal pancreatic lesions and could guide the selection of the best imaging modality for preoperative assessment, thereby optimizing resources and securing the diagnostic pathway.
