Is magnetic resonance diffusion-weighted imaging superior in the diagnosis of pancreatic adenocarcinoma and does it have a prognostic value?

摘要

AimTo assess how beneficial is adding Magnetic Resonance Diffusion-Weighted Imaging (DWI) to conventional MRI in the identification, characterization, and prognostic assessment of pancreatic duct adenocarcinoma (PDAC).Materials and MethodsWe included 34 consecutive patients with pancreatic malignancies who had conventional MRI and DWI performed and were followed up after treatment.ResultsThe apparent diffusion coefficient (ADC) values of malignant pancreatic mass lesions ranged from 0.9 to 1.5?×?10?3s/mm2at b-1000, with a mean of 1.2?±?0.18093. For the surrounding parenchyma, the ADC values were from 1.8 to 2.9?×?10?3s/mm2at b-1000, with a mean of 2.3?±?0.35506. These values showed a statistically significant difference (P?
