Performance of Magnetic Resonance Imaging-based Permeability Indices for Preoperative Glioma Grading [PDF]
Journal of Basic Research in Medical SciencesIntroduction: Due to the inherent limitations of histopathology as the gold standard method for glioma grading, in recent years, alternative methods, including methods based on imaging data, have been proposed for better glioma grading.

Application of histogram analysis for the evaluation of vascular permeability in glioma by the K2 parameter obtained with the dynamic susceptibility contrast method: Comparisons with Ktrans obtained with the dynamic contrast enhance method and cerebral blood volume [PDF]
Purpose: The “K2” value is a factor that represents the vascular permeability of tumors and can be calculated from datasets obtained with the dynamic susceptibility contrast (DSC) method.

Immune cell identity behind the Ktrans mapping of mouse glioblastoma
Magnetic Resonance Imaging, 2023Dynamic contrast-enhanced MR imaging (DCE-MRI) can assess the integrity of the blood brain barrier (BBB) and has been used in GBM patients to determine glioma grade, predict prognosis, evaluate treatment response, and differentiate treatment-induced effect from recurrence.

Correlation Between Ktrans and Microvessel Density in Different Tumors: A Meta-analysis [PDF]
Anticancer Research, 2018 Dynamic contrast-enhanced magnetic resonance imaging (DCE MRI) is a technique based on the measurement of the signal intensity of the investigated tissue before, during, and after administration of an intravenous contrast agent. DCE MRI parameters can reflect tumor angiogenesis and, therefore, can provide information about tumor behavior.

Improved Quantification of Ktrans with Cardiac Output Based Correction of Arterial Input Function
ISMRM Annual Meeting, 2023The arterial signal in DCE MRI often suffers from the inflow effect, which may cause large errors in the arterial concentration and compartmental model analysis. We implemented a constrained signal-to-concentration conversion using the subject’s cardiac output based on the Stewart-Hamilton principle, which limits the area under the arterial ...
