Geometrical differences in gross target volumes between 3DCT and 4DCT imaging in radiotherapy for non-small-cell lung cancer
The aim of this study was to explore the characteristic of 3DCT scanning phases and estimate the comparative amount of respiration motion information included in 3DCT and 4DCT by comparing the volumetric and positional difference between the volumes from 3DCT and 4DCT for the radiotherapy of non-small-cell lung cancer (NSCLC). A total of 28 patients with NSCLC sequentially underwent 3DCT and 4D...
متن کاملImpact of PET - CT motion correction in minimising the gross tumour volume in non-small cell lung cancer
AbstractObjective: To investigate the impact of respiratory motion on localization, and quantification lung lesions for the Gross Tumour Volume utilizing an in-house developed Auto3Dreg programme and dynamic NURBS-based cardiac-torso digitised phantom (NCAT). Methods: Respiratory motion may result in more than 30% underestimation of the SUV values of lung, liver and kidney tumour lesions. The m...
متن کامل(18)F-FDG avid volumes on pre-radiotherapy FDG PET as boost target delineation in non-small cell lung cancer.
BACKGROUND To investigate whether during/post-radiotherapy FDG uptake locations within tumors is likely identified using a pre-radiotherapy scan for non-small cell lung cancer (NSCLC), ultimately enabling confirm that a suitable metabolically active sub-volume pre-radiotherapy of the primary tumor for radiation boosting target. METHODS Patients with a pathologically proven inoperable stage II...
متن کاملConcurrent chemoradiotherapy in locally advanced non-small cell lung cancer: a retrospective analysis of the correlation between radiotherapy-related factors and tumor response
Background: To determine which radiotherapy parameters are associated with the tumor response of locally advanced non-small cell lung cancer (NSCLC) patients undergoing concurrent chemoradiotherapy. Materials and Methods: Thirty one patients with IIIA/IIIB NSCLC underwent chemoradiotherapy with a median dose of 63 Gy. On our actual treatments, we made radiotherapy planning to cover the planning...
متن کاملA Prospective Study Comparing Functional Imaging (18F-FDG PET) Versus Anatomical Imaging (Contrast Enhanced CT) in Dosimetric Planning for Non-small Cell Lung Cancer.
Objective(s): 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET-CT) is a well-used and established technique for lung cancer staging. Radiation therapy requires accurate target volume delineation, which is difficult in most cases due to coexisting atelectasis. The present study was performed to compare the 18F-FDG PET-CT with contrast enhanced computed tomogr...
