Assessment of extra-pancreatic perineural invasion in resectable cancer of pancreatic head with pathomorphological correlation E. Kasatkina, V. Lyadov, I. Shrainer, S. Bogomazova, E. Mershina, V. Sinitsyn; Moscow/RU
Purpose: Identification of small and isodense tumors in the pancreatic parenchyma is still a diagnostic challenge; functional imaging techniques may have the potential to overcome today’s limitations; to evaluate a feasibility study for dual energy perfusion-CT (DE-CT) in patients with small pancreatic carcinomas. Material and Methods: 25 patients with pancreatic cancer were examined with a multidetector-CT (Siemens Definition Flash) using a dynamic perfusion protocol of 34 dual-energy acquisitions every 1.5s and a range of 1.5 cm (80 ml of iodinated contrast (370 mg/ml, 5ml/s)). Analysis of the perfusion images were performed with a multimodality workplace and the Body-PCT-tool (MMWP, Siemens Medical Solutions) using the Patlak-model. Color-coded parameter maps have been generated and perfusion, permeability and blood volume values were calculated. Results: All 25 carcinomas could clearly differentiated from normal tissue in the color-coded parameter maps; n= 5/25 (20%) carcinomas appeared isodense. Using the 80 kV(p)-data mean perfusion, permeability and blood volume of malignant tissue was significantly lower with 27.23 ± 21.89 ml/100 ml/min, 42.96 ± 21.91 x 0.5 ml/100 ml/min and 38.64 ± 20.21 ml/100 ml than healthy tissue with 91,12 ± 19,93 ml/100 ml/min, 74.78 ± 15.88 x 0.5 ml/100 ml/min and 119.52 ± 52.76 ml/100 ml (p< 0.0001). Using the weighted-average 120 kV(p)-equivalent perfusion-, permeability- and blood volume-values determined from DE image data standard-deviation is distinctly smaller. Conclusion: 4D-imaging with DE-CT is feasible in pancreatic carcinomas and could be helpful for defining the carcinomas even though they are not visible in contrast-enhanced CT.

Pancreatic neuroendocrine tumor (PNET): staging accuracy and diagnostic performance of MDCT for differentiate atypical PNET from pancreatic adenocarcinoma J.H. Kim, H.W. Eun, J.M. Lee, J.K. Han, B.I. Choi; Seoul/KR Purpose: Our study investigated staging accuracy of MDCT for pancreatic neuroendocrine tumor (PNET). We also assessed diagnostic performance to differentiate atypical PNET from pancreatic adenocarcinoma. Material and Methods: Our study consisted of 109 patients with surgically proven PNET (T1=33, T2=37, T3=39, N1=20; NETG1=66, NETG2=31, NEC=12) who underwent preoperative MDCT. Two reviewers independently and retrospectively accessed T-stage, N-metastasis. They evaluated the presence or absence of predefined findings of the PNET on CT. We analyzed the typical finding and relationship between CT findings and tumor grade. Using atypical PNET, they also estimated the possibility of atypical PNET or pancreatic adenocarcinoma (n=29) using a five-point scale. ROC curve analysis, kappa statistics, Fisher’s exact test, Chi-square test were used for statistical analysis. Results: Diagnostic accuracy for T-stage was T1=92%-97%, T2= 91%-93%, T3=86%- 88% with excellent agreement (κ=0.847). Accuracy for N-metastasis was 83%-89% with moderate agreement (κ=0.614). Typical CT findings included well circumscribed, homogeneous enhanced, hypervascular on arterial and venous phase, which were more common in lower grade tumor (p

Material and Methods: 25 patients with pancreatic cancer were examined with a multidetector-CT (Siemens Definition Flash) using a dynamic perfusion protocol of 34 dual-energy acquisitions every 1.5s and a range of 1.5 cm (80 ml of iodinated contrast (370 mg/ml, 5ml/s)). Analysis of the perfusion images were performed with a multimodality workplace and the Body-PCT-tool (MMWP, Siemens Medical Solutions) using the Patlak-model. Color-coded parameter maps have been generated and perfusion, permeability and blood volume values were calculated. Results: All 25 carcinomas could clearly differentiated from normal tissue in the color-coded parameter maps; n= 5/25 (20%) carcinomas appeared isodense. Using the 80 kV(p)-data mean perfusion, permeability and blood volume of malignant tissue was significantly lower with 27.23 ± 21.89 ml/100 ml/min, 42.96 ± 21.91 x 0.5 ml/100 ml/min and 38.64 ± 20.21 ml/100 ml than healthy tissue with 91,12 ± 19,93 ml/100 ml/min, 74.78 ± 15.88 x 0.5 ml/100 ml/min and 119.52 ± 52.76 ml/100 ml (p< 0.0001). Using the weighted-average 120 kV(p)-equivalent perfusion-, permeability- and blood volume-values determined from DE image data standard-deviation is distinctly smaller. Conclusion: 4D-imaging with DE-CT is feasible in pancreatic carcinomas and could be helpful for defining the carcinomas even though they are not visible in contrast-enhanced CT.

Pancreatic neuroendocrine tumor (PNET): staging accuracy and diagnostic performance of MDCT for differentiate atypical PNET from pancreatic adenocarcinoma J.H. Kim, H.W. Eun, J.M. Lee, J.K. Han, B.I. Choi; Seoul/KR Purpose: Our study investigated staging accuracy of MDCT for pancreatic neuroendocrine tumor (PNET). We also assessed diagnostic performance to differentiate atypical PNET from pancreatic adenocarcinoma. Material and Methods: Our study consisted of 109 patients with surgically proven PNET (T1=33, T2=37, T3=39, N1=20; NETG1=66, NETG2=31, NEC=12) who underwent preoperative MDCT. Two reviewers independently and retrospectively accessed T-stage, N-metastasis. They evaluated the presence or absence of predefined findings of the PNET on CT. We analyzed the typical finding and relationship between CT findings and tumor grade. Using atypical PNET, they also estimated the possibility of atypical PNET or pancreatic adenocarcinoma (n=29) using a five-point scale. ROC curve analysis, kappa statistics, Fisher’s exact test, Chi-square test were used for statistical analysis. Results: Diagnostic accuracy for T-stage was T1=92%-97%, T2= 91%-93%, T3=86%- 88% with excellent agreement (κ=0.847). Accuracy for N-metastasis was 83%-89% with moderate agreement (κ=0.614). Typical CT findings included well circumscribed, homogeneous enhanced, hypervascular on arterial and venous phase, which were more common in lower grade tumor (p
