Mavroidis, P.; Vlachopoulou, A.; Kostopoulos, S.; Ninos, C.; Glotsos, D.; Bakas, A.; Oikonomou, G.; Roka, V.; Kapsalaki, E.; Tsirika, A.; Papanikolaou, N.; Stathakis, S.; Lavdas, E. (2015) -
Comparison of BLADE and conventional T2-TSE sequences for the sagittal visualization of the cervical spinal cord in multiple sclerosis patients - A case report
Lavdas, E.; Mavroidis, P.; Topaltzikis, T.; Slatinopoulos, V.; Roka, V.; Vlachopoulou, A.; Papanikolaou, N.; Stathakis, S.; Kapsalaki, E.; Batsikas, G. (2013)The purpose of this study is to report the significant differences found in the identification of lesions in cervical spinal cord of two patients with multiple sclerosis when using the BLADE T2-TSE and BLADE T2-TIRM sequences ... -
A comparison of Monte Carlo simulation with experimental dosimetric techniques for a 6 MV stereotactic radiotherapy unit
Tsougos, I. M.; Theodorou, K.; Bazioglou, M. A.; Stathakis, S.; Kappas, C. (2004)Purpose: To compare Monte Carlo simulation with conventional dosimetry techniques for stereotactic radiotherapy (SRT), since accurate dosimetry of narrow photon beams is very complicated and has often been questioned, ... -
Comparison of PD BLADE with fat saturation (FS), PD FS and T2 3D DESS with water excitation (WE) in detecting articular knee cartilage defects
Lavdas, E.; Topalzikis, T.; Mavroidis, P.; Kyriakis, I.; Roka, V.; Kostopoulos, S.; Glotsos, D.; Zilidis, C.; Stathakis, S.; Tsagkalis, A.; Papanikolaou, N.; Batsikas, G.; Arvanitis, D. L.; Vassiou, K. (2013)The purpose of this study, is to compare the sequences: 1) proton density (PD) BLADE (BLADE is a PROPELLER-equivalent implementation of the Siemens Medical System) with fat saturation (FS) coronal (COR), 2) PD FS COR, 3) ... -
Dosimetric and radiobiological evaluation of dose distribution perturbation due to head heterogeneities for Linac and Gamma Knife stereotactic radiotherapy
Theodorou, K.; Stathakis, S.; Lind, B.; Kappas, C. (2008)Introduction. In SRT/SRS, dedicated treatment planning systems are used for the calculation of the dose distribution. The majority of these systems utilize the standard TMR/OAR formalism for dose calculation as well as ... -
Elimination of motion, pulsatile flow and cross-talk artifacts using blade sequences in lumbar spine MR imaging
Lavdas, E.; Mavroidis, P.; Kostopoulos, S.; Glotsos, D.; Roka, V.; Koutsiaris, A. G.; Batsikas, G.; Sakkas, G. K.; Tsagkalis, A.; Notaras, I.; Stathakis, S.; Papanikolaou, N.; Vassiou, K. (2013)The purpose of this study is to evaluate the ability of T2 turbo spin echo (TSE) axial and sagittal BLADE sequences in reducing or even eliminating motion, pulsatile flow and cross-talk artifacts in lumbar spine MRI ... -
An inhomogeneity correction algorithm for irregular fields of high-energy photon beams based on Clarkson integration and the 3D beam subtraction method
Stathakis, S.; Kappas, C.; Theodorou, K.; Papanikolaou, N.; Rosenwald, J. C. (2006)A number of treatment-planning systems still use conventional correction methods for body inhomogeneities. Most of these methods (power law method, tissue-air ratio (TAR), etc.) consider only on-axis points, rectangular ... -
Monte Carlo dosimetric evaluation of high energy vs low energy photon beams in low density tissues
Tsiakalos, M. F.; Stathakis, S.; Plataniotis, G. A.; Kappas, C.; Theodorou, K. (2006)Background and purpose: Low megavoltage photon beams are often the treatment choice in radiotherapy when low density heterogeneities are involved, because higher energies show some undesirable dosimetric effects. This work ... -
Monte Carlo dosimetric evaluation of using high energy vs low energy beams in low density materials
Stathakis, S.; Tsiakalos, M.; Plataniotis, G.; Kappas, K.; Theodorou, K. (2004)
