Article Synopsis
- - The study investigates the reliability of Diffusion Kurtosis Imaging (DKI) parameters by comparing them with perfusion metrics from Dynamic Contrast Enhanced (DCE) and Dynamic Susceptibility Contrast (DSC) MRI techniques in primary central nervous system lymphoma (PCNSL) patients.
- - Analysis of 15 lesions from patients with Epstein-Barr Virus negative PCNSL showed significant correlations, notably between DKI parameters and both DCE/DSC metrics, suggesting that DKI adds valuable insights beyond traditional diffusion models.
- - The findings indicate a strong inverse correlation between several DKI parameters and perfusion metrics, pointing to DKI's potential to enhance understanding of tumor characteristics and inform clinical practices.
Article Synopsis
- The study evaluated the effectiveness of MRI sequences (T1-TSE, T2-TSE, and 3D FLAIR) with and without the Compressed-SENSE technique by measuring contrast, contrast-to-noise ratio (CNR), and signal-to-noise ratio (SNR).
- A total of 142 MRI images were analyzed, with regions of interest marked by radiologists to assess differences in CNS structures (white matter, grey matter, cerebrospinal fluid).
- Results showed that while Compressed-SENSE improved image quality in specific T1-TSE sequences, it had mixed effects on contrast values in other sequences, ultimately demonstrating its potential for faster MRI scans without compromising essential diagnostic information.
Peliosis hepatis (PH) is a rare benign pathological entity characterised by dilatation of the hepatic sinusoids. It has been reported to be associated with infection or malignancy, but the aetiology of PH remains unknown. Distinguishing PH from other malignancies can be difficult on imaging studies.

For this reason, acquisition times of <10 min may cause inaccurate estimation of pharmacokinetic parameters. Since no studies have been conducted on the influence of long scan times on DCE-MRI parameters in brain tumors, the aim of this study is to investigate the variation of DCE-MRI-derived kinetic parameters as a function of acquisition time, from 5 to 10 min in brain tumors.

It is classically associated with structural and functional changes in the optic nerve head and retinal nerve fiber layer, but the damage is not limited to the eye. The involvement of the central visual pathways and disruption of brain network organization have been reported using advanced neuroimaging techniques.
