Grading of gliomas using transfer learning on MRI images
DiscussionIt was demonstrated that developing Computer-aided Diagnosis (CAD) systems using pre-trained CNNs and classification algorithms is a functional approach to automatically specify the grade of glioma brain tumours in MRI images. Using these models is an excellent alternative to invasive methods and helps doctors diagnose more accurately before treatment. (Source: Magnetic Resonance Materials in Physics, Biology and Medicine)

Reliability of velocity pulsatility in small vessels on 3Tesla MRI in the basal ganglia: a test –retest study
This study assessed the test–retest reliability of 3T MRI blood flow velocity measurements in perforating arteries in the BG.Materials and methodsTwo-dimensional phase-contrast cardiac gated (2D-PC) images were acquired for 35 healthy controls and repeated with and without repositioning. 2D-PC images were processed and analyzed, to assess the number of detected perforating arteries (Ndetected), mean blood flow velocity (Vmean), and velocity pulsatility index (vPI). Pairedt-tests and Bland –Altman plots were used to compare variance in outcome parameters with and without repositioning, and limits of agreement (LoA) were...

Effects of bolus injection duration on perfusion estimates in dynamic CT and dynamic susceptibility contrast MRI
This study investigates whether these discrepancies regarding CBF and MTT between CTP and DSC-MRI can be attributed to the different injection durations of these techniques. Five subjects were scanned using CTP and DSC-MRI. Region-wise estimates of CBF, MTT, and cerebral blood volume (CBV) were derived based on oscillatory index regularized singular value decomposition. A parametric model that reproduced the shape of measured time curves and characteristics of resulting perfusion parameter estimates was developed and used to simulate data with injection durations typical for CTP and DSC-MRI for a clinically relevant set of...
