Arachnoid Cysts: The Role of the BLADE Technique
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) -
Changes in pituitary response to gonadotropin releasing hormone following bilateral ovariectomy in women treated with follicle-stimulating hormone
Messinis, I. E.; Milingos, S.; Kollios, G.; Seferiadis, K.; Papanikolaou, N.; Lolis, D. (1996)Superovulation induction in women attenuates the pituitary response to gonadotropin-releasing hormone (GnRH). The aim of this study was to assess the duration of the suppressing activity of the ovaries on the pituitary. ... -
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 ... -
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) ... -
Cyclopia and exadactyly: CT and MRI findings
Karantanas, A. H.; Papanikolaou, N.; Danos, A.; Antonakopoulos, G. (1999)Cyclopia is a congenital abnormality consisting of fused orbits and a single eye and is the most extreme form of alobar holoprosencephaly. The present case describes the CT and MRI findings in the skull of a 33-week-old ... -

(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 ...
