Abstract

To assess the accuracy of magnetic resonance (MR) with Mangafodipir (Mn-DPDP) in the identification of focal solid pancreatic lesions. The possibility of lesion characterisation based on quantification of Mn uptake was also investigated. Thirty-four patients (11 females, 23 males, aged 21-75, mean age 57) selected at sonography (US) and spiral CT (SCT) for clinically suspected focal solid pancreatic lesion, were studied between June 2000 and July 2001. Patients eligible for surgery underwent MR imaging (1.5 T) before and after infusion of 5 micromol/kg of Mn-DPDP (0.5 ml/kg Teslascan, Nycomed Amersham Health, Oslo, Norway). The baseline examination included FSE T2-weighted sequences and fat-saturated and non fat-saturated breath-hold gradient-echo T1-weighted sequences (FMP SPGR). After Teslascan infusion, fat-saturated and non fat-saturated FMP SPGR sequences were repeated. Thirty of the 34 patients had a definitive diagnosis provided by reference standards such as post-operative histology (22 cases), cytology (FNAB) and/or a follow-up period of at least 6 months (8 patients). As regards lesion characterisation, the signal-to-noise ratio (S/N ratio) and contrast-to-noise ratio (C/N ratio) of lesions compared to the pancreatic ...Continue Reading
