64-row mdCt perfusion of the pancreas: first results of the use of time-density curve morphology in discriminating between normal parenchyma, adenocarcinoma, chronic pancreatitis and endocrine tumors G.A. Zamboni, L. Bernardin, M. Contini, R. Pozzi Mucelli; Verona/IT purpose: The purpose of our study is to evaluate the use of time-density curves obtained from MDCT perfusion scans of the pancreas for the characterization of normal parenchyma, adenocarcinoma, chronic pancreatitis and endocrine tumors. material and methods: In this IRB-approved prospective study, 37 patients underwent a 90-second perfusion 64-row MDCT scan of the pancreas after injection of 70 cc of a 350 mgI/ml solution at 5 cc/s. 52 time-density curves were
Comparison of free breathing versus breathhold in perfusion imaging using dynamic volume Ct S. Kandel1, H. Meyer2, P. Rogalla1; 1Toronto, ON/CA, 2Berlin/DE purpose: To compare two scanning protocols (free breathing versus breathhold) using dynamic volume CT scanning and to evaluate their effects on manual rigid image registration. material and methods: 40 patients (mean age 65 years; 29 men; 11 women) underwent dynamic volume CT for perfusion analysis of focal pancreatic lesion and were randomly assigned to either free breathing (I) or multiple breathhold (II) group. CT scanning was performed using a 320-slice dynamic volume scanner after administration of contrast media. Patients were prepared with oxygen hyperventilation through a mask. Both dynamic CT protocols consisted of 15 intermittent low dose scans which were applied within 90 seconds. Group I was instructed to breathe as shallowly as possible during the entire examination. The longest breathhold sequence for group II lasted for 40 seconds. During post-processing, the scan with the highest contrast was determined as reference for manual rigid registration and every image was visually matched focused on the target lesion in the pancreas. The image mismatch per patient was calculated as the median of the 3D vector lengths of the registration offset. Statistic analysis was performed using the Wilcoxon rank sum test with continuity correction. results: In all 40 patients, focused rigid image registration was feasible. 8% of the scans in group I and 14% in group II did not require manual registration. The median registration shift for group I and II was 2.61 and 4.95 mm, respectively (p< 0.005). Conclusion: Free breathing during dynamic volume CT scanning reduces the required amount of motion correction necessitating less overall user interaction.
SS 1.05
First results of 64-row mdCt perfusion in the characterization of focal solid pancreatic lesions G.A. Zamboni, L. Bernardin, M. Contini, N. Faccioli, M. D’Onofrio, R. Pozzi Mucelli; Verona/IT purpose: To evaluate the use of MDCT perfusion of the pancreas for the characterization of solid focal pancreatic lesions. material and methods: 25 patients (12 males, 13 females; mean age, 61.2 years) with solid focal pancreatic lesions were prospectively enrolled and underwent a 120-second perfusion 64-row MDCT examination after injection of 70 cc of a 350 mgI/ml solution at 5 cc/s. 21 patients were diagnosed with adenocarcinoma and 4 with endocrine tumors: all diagnoses were confirmed at pathology of the resected specimen or at fine needle aspiration cytology. Mean diameter was 3 cm for adenocarcinomas and 4.2 cm for endocrine tumors. Tumor perfusion, positive-enhancement-integral (PEI), time-to-peak (TTP) and blood-volume (BV) were determined on a commercially available workstation (Brilliance Workspace 2.0, Philips Medical Systems), analyzing the slice with the largest tumor diameter. The perfusion parameters for the two tumors were compared using an unpaired t-test. results: MDCT perfusion was performed successfully, providing datasets that could be analyzed in all patients. A very significant difference was observed between adenocarcinomas and endocrine tumors for perfusion (17.3 vs 135.2; p
