Comparison of Different Methods for Delineation of 18F-FDG PET–Positive Tissue for Target Volume Definition in Radiotherapy of Patients with Non–Small Cell Lung Cancer
Ursula Nestle,Stephanie Kremp,Andrea Schaefer-Schuler,Christiane Sebastian-Welsch,Dirk Hellwig,Christian Rübe,Carl-Martin Kirsch +6 more
TL;DR: The different techniques of tumor contour definition by (18)F-FDG PET in radiotherapy planning lead to substantially different volumes, especially in patients with inhomogeneous tumors.
Journal ArticleDOI
18F-deoxyglucose positron emission tomography (FDG-PET) for the planning of radiotherapy in lung cancer: high impact in patients with atelectasis.
Ursula Nestle,K. Walter,Sylvia Schmidt,Norbert Licht,C Nieder,Babak Motaref,Dirk Hellwig,Marcus Niewald,Dieter Ukena,Carl M. Kirsch,Gerhard W. Sybrecht,Klaus Schnabel +11 more
TL;DR: In this retrospective analysis, the information provided by FDG-PET would have contributed to a substantial reduction of the size of radiotherapy portals, particularly for patients with tumor-associated dys- or atelectasis.
Journal ArticleDOI
F-18 fluorodeoxyglucose PET in vivo evaluation of pancreatic glucose metabolism for detection of pancreatic cancer.
R. Bares,P. Klever,S Hauptmann,Dirk Hellwig,J. Fass,U. Cremerius,V. Schumpelick,C. Mittermayer,U. Büll +8 more
TL;DR: FDG PET has the potential to improve the detection of lymphadenopathy and the differential diagnosis of pancreatic masses and was superior to CT and US in detection of node metastases.
Journal ArticleDOI
18F-FDG PET for Mediastinal Staging of Lung Cancer: Which SUV Threshold Makes Sense?
Dirk Hellwig,Thomas P Graeter,Dieter Ukena,Andreas Groeschel,Gerhard W. Sybrecht,Hans-Joachim Schaefers,Carl-Martin Kirsch +6 more
TL;DR: For mediastinal staging, the choice of an SUV of 2.5 as the threshold is justified because FNR + FPR is minimized, and the resulting high negative predictive value of 96% allows the omission of mediastinoscopy in patients with negative mediastsinal findings on 18F-FDG PET images.
