3D-Quantitated Single Photon Emission Computed Tomography/Computed Tomography: Impact on intended Management Compared to Lung Perfusion Scan in Marginal Candidates for Pulmonary Resection.

Objectives: Based on previous studies, single-photon emission computed tomography/computed tomography (SPECT/CT) has been proven more accurate and reproducible than planar lung perfusion scintigraphy to assess lobar perfusion. However, the impact of 3D-quantitated SPECT/CT on intended management in functionally marginal candidates for pulmonary resection is unknown. The evaluation of this impact was the main aim of this study.

Simplified dual time point FDG-PET/computed tomography for determining dignity of pancreatic lesions.

Background: Predicting the dignity of pancreatic lesions is still a diagnostic challenge. The differentiation between benign changes in chronic pancreatitis from pancreatic cancer remains difficult. Therefore, the aim of this study was to evaluate whether early dual time point kinetics of pancreatic lesions in 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) may be helpful to differentiate pancreatic lesions.
