Chemotherapy response evaluation with 18F-FDG PET in patients with non-small cell lung cancer.

Unlabelled: The aim of this prospective study was to evaluate the value of (18)F-FDG PET for the assessment of chemotherapy response in patients with non-small cell lung cancer. Furthermore, part of the objective of this study was to compare 2 methods to quantify changes in glucose metabolism.

Methods: In 51 patients, dynamic (18)F-FDG PET was performed before and at 5-8 wk into treatment.

The outcome of a long-term follow-up of pancreatic function after recovery from acute pancreatitis.

Context: It is generally assumed that pancreatic function recovers completely after mild but not after severe acute pancreatitis.

Objective: To evaluate both pancreatic function and quality of life in patients who had recovered from acute pancreatitis in a long-term follow-up study.

Participants: Thirty-four patients (mean age: 56 years) who had recovered from biliary (n=26) or post ERCP (n=8) acute pancreatitis.

Comparison of image-derived and arterial input functions for estimating the rate of glucose metabolism in therapy-monitoring 18F-FDG PET studies.

Unlabelled: The use of dynamic (18)F-FDG PET to determine changes in tumor metabolism requires tumor and plasma time-activity curves. Because arterial sampling is invasive and laborious, our aim was to validate noninvasive image-derived input functions (IDIFs).

Methods: We obtained 136 dynamic (18)F-FDG PET scans of 76 oncologic patients.
