Comparison of PET/CT and CT-based tumor delineation and its effects on the radiation treatment planning for non-small cell lung cancer
Introduction: Tumor volume delineation is the most important step in the radiation treatment planning. In this study the impact of PET/CT data on the tumor delineation precision of non-small cell lung cancer (NSCLC) was investigated. Methods: PET/CT images of 20 patients with primary NSCLC were obtained and imported to the treatment planning system for im...
متن کاملEvaluation and comparison of New 4DCT based strategies for proton treatment planning for lung tumors
PURPOSE To evaluate different strategies for proton lung treatment planning based on four-dimensional CT (4DCT) scans. METHODS AND MATERIALS Twelve cases, involving only gross tumor volumes (GTV), were evaluated. Single image sets of (1) maximum intensity projection (MIP3) of end inhale (EI), middle exhale (ME) and end exhale (EE) images; (2) average intensity projection (AVG) of all phase im...
متن کاملCT and PET/CT fusion for lung cancer biopsy planning.
Cherkashin M, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-221972 Description A 79-year-old man presented with colorectal cancer T4aN0M0 (surgery at 2016) and a newly diagnosed (by chest CT scan) left lung tumour (77×35×51 mm) with hydrothorax in March 2017. Initially, case was suspected as metastatic and 18-fluorodeoxyglucose whole body positron emission tomography (PET)/ CT for staging was ...
متن کاملComparative evaluation of CT-based and PET/4DCT-based planning target volumes in the radiation of primary esophageal cancer.
PURPOSE To compare planning target volume (PTV) defined by PET combined with 4DCT to 3DCT and 4DCT. METHODS Eighteen (18/30) esophageal cancer patients who underwent 3DCT, 4DCT and (18)F-FDG PET-CT thoracic simulation with SUVmax≥2.0 of the primary volume were enrolled. CTV3D was formed on 3DCT by adding a margin of 30 mm in cranial-caudal direction and 5 mm in transversal direction. PTV3D wa...
متن کاملComparison of biological target volume metrics based on FDG PET-CT and 4DCT for primary non-small-cell lung cancer
Fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) and four-dimensional CT (4DCT) are used in several methods for defining the biological target volume (BTV) in primary non-small cell lung cancer (NSCLC). Disagreements between the assessments using these methodologies make the use of BTV for radiotherapy planning controversial. In this study, we compared existing metho...
