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 کاملTumour radiobiology beyond fractionation
Historically it has been shown repeatedly that single high doses of radiation do not allow a therapeutic differential between tumor and critical normal tissues but dose fractionation does. The purpose of conventional dose fractionation is to increase dose to the tumor while preserving normal tissue function. Tumors are generally irradiated with 2Gy dose per fraction delivered daily to a more or...
متن کاملCongruency of tumour volume delineated by FET PET and MRSI.
Institute of Neuroscience and Medicine, Forschungszentrum Jülich, Germany In addition to MR imaging, PET imaging of O-(2-[18F]Fluorethyl)-L-Tyrosine (FET) uptake provides information on brain tumour extent and metabolic activity. Similarly, MRS has been shown to be of value for distinguishing highfrom low-grade gliomas. Based on 2D spatially resolved MRSI, an overlap between 18FET uptake and th...
متن کاملTumour volume and lung metastasis in patients with osteosarcoma.
PURPOSE To assess the association between tumour volume and occurrence of lung metastasis in patients with osteosarcoma and to determine the cut-off value. METHODS Records of 70 patients with histopathologically confirmed primary osteosarcoma in the extremities who had magnetic resonance imaging and computed tomography of the thorax less than one month before treatment were reviewed, with ref...
