UMRAM Researcher Davud İbrahim Mahçiçek leaves UMRAM to work on his Ph.D. degree in Middle East Technical University.

Funda Yıldırım is working towards her Ph.D.degree in Groningen University where she has been granted acceptance, Gizem Küçük is now in University of New York with the same purpose.

Our Post Doctoral Fellow Özgür Yılmaz starts in ASELSAN as an engineer.

Aslıhan Ors who also worked in UMRAM in a postdoc position, is to continue her academic carrier in Bilecik University as an Assistant Professor.

Begüm Erten also choose to leave UMRAM to concentrate more on her master degree in METU. 

We would like to thank them for their contributions to UMRAM and we wish them all good luck on their chosen path.

We celebrated their achievements and farewell them with a cosy party.

Prof. Dr Kader Karlı Oğuz of Hacettepe University, Department of Radiologyis to work in UMRAMfor a year to conduct researches on Neuroradiology together with the other researchersin the Centre . This studies are expected to be highlybenefical for both theengineers and the students alike.

Dr.Oguz has been specialized on MR imaging in the fields of inherited metabolic, and neurodegenerative diseases, epilepsy, congenital anomalies, stroke and advanced clinical applications in these issues.

 

A new method was intoduced to solve for the induced  currents on leads inside a bodily tissue. 

Researchers of UNAM and researchers of UMRAM of BIlkent University joined forced with researchers of TUBITAK-UME (National Metrology Institute) to propose a new contrast agent. Article entitled "Peptide functionalized superparamagnetic iron oxide nanoparticles as MRI contrast agents" has been published in Journal of Material Chemistry online with DOI: 10.1039/c1jm11387a. The authors of the manuscript are Selim Sulek, Busra Mammadov, Davut I. Mahcicek, Huseyin Sozeri, Ergin Atalar, Ayse B. Tekinay and Mustafa O. Guler.

Ergin Atalar has been nominated to the executive board of European Society of Magnetic Resonance in Medicine and Biology by its board.

Oktay Algin of Ataturk Hospital authored an American Journal of Neuroradiology article using the resourses at UMRAM facilities. The citation of the article is "Algin O., Turkbey B.

Abstract: Diffusion MRI is a magnetic resonance imaging (MRI) method that provides information about random microscopic motion of water molecules in biological tissues. In addition to providing a higher sensitivity for the diagnosis of white matter related diseases such as stroke and multiple sclerosis, and producing connectivity maps of the brain, it is a promising prognostic tool in the assessment and treatment response monitoring of cancer in the body.

 

While high in-plane resolution is desirable for all diffusion MRI applications, it is particularly essential for the diffusion-weighted imaging (DWI) of small structures. In the first part of this talk, I will present advanced pulse sequence methods to overcome the problems associated with and enable high-resolution diffusion MRI of targeted regions. In addition to validating the performance of the proposed methods outside the central nervous system, example cases from an extensive clinical evaluation of the high-resolution diffusion MRI of spinal cord will be presented.

 

In the second part of my talk, I will introduce magnetic particle imaging (MPI): a new and powerful imaging modality with high contrast, high resolution and high sensitivity in detecting the spatial distribution of magnetic tracers in animals and human body. MPI exploits the nonlinear response of super-paramagnetic iron oxide nanoparticles to oscillating magnetic fields. With application ranging from in vivo stem cell tracking to angiography, MPI promises superior contrast and sensitivity over existing medical imaging modalities.

 

BIO: Emine Ülkü Sarıtaş graduated with a B.S. degree in Electrical & Electronics Engineering from Bilkent University in 2002. She received her Ph.D. degree in Electrical Engineering at Stanford University in 2009, working under the supervision of Prof. Dwight Nishimura on high-resolution diffusion magnetic resonance imaging. She is currently a postdoctoral fellow in Prof. Steven Conolly’s Imaging Systems Lab in the Department of Bioengineering at the University of California, Berkeley. Her current research focuses on the development of magnetic particle imaging techniques, as well as their safety and image reconstruction algorithms.
