Dosimetric and Radiobiological Evaluation of Multiparametric MRI-guided Dose Painting in radiotherapy of Prostate Cancer
Introduction: Radiotherapy is one of the treatment options for locally advanced prostate cancer, however with standard radiation doses it is not always very effective. One of the strategies to improve the efficiency of radiotherapy is increasing the dose. In this study to increase tumor local control rates a new radiotherapy method, known as dose painting (DP) was investigated....
متن کاملIntegration method of 3D MR spectroscopy into treatment planning system for glioblastoma IMRT dose painting with integrated simultaneous boost
BACKGROUND To integrate 3D MR spectroscopy imaging (MRSI) in the treatment planning system (TPS) for glioblastoma dose painting to guide simultaneous integrated boost (SIB) in intensity-modulated radiation therapy (IMRT). METHODS For sixteen glioblastoma patients, we have simulated three types of dosimetry plans, one conventional plan of 60-Gy in 3D conformational radiotherapy (3D-CRT), one 6...
متن کاملMetabolic and electrophysiological validation of functional MRI.
OBJECTIVES Although functional MRI is widely used for preoperative planning and intraoperative neuronavigation, its accuracy to depict the site of neuronal activity is not exactly known. Experience with methods that may validate fMRI data and the results obtained when coregistering fMRI with different preoperative and intraoperative mapping modalities including metabolically based (18)F-fluorod...
متن کاملIntegration of Functional MRI, Structural MRI, EEG, and MEG
The combination of functional Magnetic Resonance Imaging (fMRI) with Electroencephalography (EEG) and Magnetoencephalography (MEG) source reconstruction techniques promises to add temporal resolution in the [ms] range to fMRI activation maps. Depending on the available information, different co-registration methods for merging structural Magnetic Resonance Imaging (sMRI) and fMRI coordinate sys...
متن کاملTheragnostic imaging for radiation oncology : dose - painting
112 http://oncology.thelancet.com Vol 6 February 2005 Diagnostic imaging, from radiographs to CT, has been used throughout the history of radiotherapy to define the site to which the radiation should be delivered for patients with cancer. Theragnostic imaging is a method by which the radiation dose can be delivered in the four dimensions of space and time to achieve the optimum outcome after ra...
