We propose a method for the automated identification of key white matter fiber tracts for neurosurgical planning, and we apply the method in a retrospective study of 18 consecutive neurosurgical patients with brain tumors. Our method is designed to b

Image Registration to Compensate for EPI Distortion in Patients with Brain Tumors: An Evaluation of Tract-Specific Effects

Autor: Walid Ibn Essayed, Laura Rigolo, Pelin Aksit Ciris, Fan Zhang, Yogesh Rathi, Olutayo Olubiyi, Pegah Kahali, Isaiah Norton, Chantal M. W. Tax, Prashin Unadkat, Alexandra J. Golby, Angela Albi, Lauren J. O'Donnell, Antonio Meola

Publikováno v: Journal of Neuroimaging. 28:173-182

BACKGROUND AND PURPOSE Diffusion magnetic resonance imaging (dMRI) provides preoperative maps of neurosurgical patients’ white matter tracts, but these maps suffer from echo-planar imaging (EPI) distortions caused by magnetic field inhomogeneities.

Characterization of gradient echo signal decays in healthy and cancerous prostate at 3T improves with a Gaussian augmentation of the mono-exponential (GAME) model

Autor: Junichi Tokuda, Robert V. Mulkern, Kemal Tuncali, Clare M. Tempany-Afdhal, Tobias Penzkofer, Ravi Teja Seethamraju, Fiona M. Fennessy, Jonathan Scalera, Mukund Balasubramanian, Pelin Aksit Ciris

Publikováno v: NMR in Biomedicine. 29:999-1009

A biomarker of cancer aggressiveness, such as hypoxia, could substantially impact treatment decisions in the prostate, especially radiation therapy, by balancing treatment morbidity (urinary incontinence, erectile dysfunction, etc.) against mortality

Characterizing gradient echo signal decays in gynecologic cancers at 3T using a Gaussian augmentation of the monoexponential (GAME) model

Autor: Pelin Aksit Ciris, Antonio L. Damato, Mukund Balasubramanian, Ravi Teja Seethamraju, Akila N. Viswanathan, Clare M. Tempany-Afdhal, Robert V. Mulkern

Publikováno v: Journal of Magnetic Resonance Imaging. 44:1020-1030

Purpose To assess whether R2* mapping with a standard Mono-Exponential (ME) or a Gaussian Augmentation of the Mono-Exponential (GAME) decay model better characterizes gradient-echo signal decays in gynecological cancers after external beam radiation

Dual-Pathway sequences for MR thermometry: When and where to use them

Autor: Lawrence P. Panych, Cheng-Chieh Cheng, Pelin Aksit Ciris, Chang-Sheng Mei, Bruno Madore

Publikováno v: Magnetic Resonance in Medicine. 77:1193-1200

Purpose Dual-pathway sequences have been proposed to help improve the temperature-to-noise ratio (TNR) in MR thermometry. The present work establishes how much of an improvement these so-called "PSIF-FISP" sequences may bring in various organs and ti

Non-invasive quantification of absolute cerebral blood volume during functional activation applicable to the whole human brain

Autor: Maolin Qiu, Robert Todd Constable, Pelin Aksit Ciris

Publikováno v: Magnetic Resonance in Medicine. 71:580-590

Purpose Cerebral blood volume (CBV) changes in many diverse pathologic conditions, and in response to functional challenges along with changes in blood flow, blood oxygenation, and the cerebral metabolic rate of oxygen. The feasibility of a new metho

O ‐space imaging: Highly efficient parallel imaging using second‐order nonlinear fields as encoding gradients with no phase encoding

Autor: Jason P. Stockmann, Gigi Galiana, Leo Tam, Pelin Aksit Ciris, R. Todd Constable

Publikováno v: Magnetic Resonance in Medicine. 64:447-456

Recent improvements in parallel imaging have been driven by the use of greater numbers of independent surface coils placed so as to minimize aliasing along the phase-encode direction(s). However, gains from increasing the number of coils diminish as
