Combined PET/CT-perfusion in patients with head and neck cancers


Veit-Haibach, P; Schmid, D; Strobel, K; Soyka, J D; Schaefer, N G; Haerle, S K; Huber, G F; Studer, G; Seifert, Burkhardt; Hany, T F (2013). Combined PET/CT-perfusion in patients with head and neck cancers. European Radiology, 23(1):163-173.

Abstract

OBJECTIVES: Computed tomography perfusion (CTP) can provide information about angiogenesis and blood-flow characteristics in tumours. [18F]Fluoro-2-deoxy-D: -glucose-positron emission tomography/computed tomography (FDG-PET/CT) is one of the major oncological imaging techniques which provides information about viability of the tumour cell and partly also about its aggressiveness. The aim of the study was to investigate the relationship between FDG and CTP data in patients with head and neck cancers. MATERIALS AND METHODS: Forty-one patients with a clinically suspected head and neck cancer were prospectively included. All patients underwent a combined PET/CT with an integrated CTP examination in the area of the head and neck tumour. CTP data (BF, BV and MTT) and PET data (SUVmax, SUVmean, TLG, PETvol) were compared between tumours and (1) healthy contralateral tissue, (2) inflammatory lesions, (3) metastatic lymph nodes, and CTP data and PET data were correlated in tumours. RESULTS: Thirty-five patients had a head and neck cancer. All CTP data were statistically different between tumours, inflammatory lesions, healthy tissue and metastatic lymph nodes; PET/CT data were in part significantly different. CTP and PET parameters were not significantly correlated. CONCLUSION: CTP and PET parameters were not significantly correlated; thus, the additional CTP values provide additional insights into tumour behaviour and their glycolytic status. KEY POINTS : • Computed tomography perfusion (CTP) can be performed in combined positron emission tomography (PET)/CT. • CTP in addition to PET provides additional insights into tumour behaviour. • CTP can possibly differentiate between head and neck tumours and inflammatory lesions. • PET/CT with integrated CTP is possible without additional contrast media.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
