Modeling the Intermediate Flow Regime in Flow‐Compensated Intravoxel Incoherent Motion MRI

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3476-3487, June 2026.
ABSTRACT Purpose The intravoxel incoherent motion (IVIM) model is commonly used to separate the effects of motion related to diffusion and blood microcirculation (perfusion) on the MR signal. Depending on the encoding time (T), it is possible to probe the different temporal regimes of blood motion, which resemble a ballistic flow at short T and a ...

On‐Scanner Correction of Gradient Nonlinearity Bias for Accurate Assessment of Diffusion Heterogeneity Across Bone Sites in Myelofibrosis Patients

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3386-3395, June 2026.
ABSTRACT Purpose To improve accuracy of apparent diffusion coefficient (ADC) measurement across different bone‐marrow (BM) sites for myelofibrosis (MF) patients. Methods Vendor‐provided ADC gradient nonlinearity correction (GNC) was implemented for 41 MF study subjects on a 3T clinical scanner.

Toward Optimized Intravoxel Incoherent Motion (IVIM) and Compartmental T2 Mapping in Abdominal Organs

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3161-3175, June 2026.
ABSTRACT Purpose To quantitatively assess the bias in the intravoxel incoherent motions (IVIM)–derived pseudo‐diffusion volume fraction (f) caused by the differences in relaxation times between the tissue and fluid compartments, and to develop a two‐dimensional (b‐value‐TE) fitting approach for simultaneous T2 and IVIM parameter estimation along with ...

Automated Coregistered Segmentation for Volumetric Analysis of Multiparametric Renal MRI

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3519-3535, June 2026.
ABSTRACT Purpose This study aims to develop and evaluate a fully automated deep learning‐driven postprocessing pipeline for multiparametric renal MRI, enabling accurate kidney alignment, segmentation, and quantitative feature extraction within a single efficient workflow. Methods Our method has three main stages.

The importance of longitudinal evaluation using DAT‐SPECT in organophosphate‐induced toxic parkinsonism

Psychiatry and Clinical Neurosciences Reports, Volume 5, Issue 2, June 2026.
We performed longitudinal evaluation using magnetic resonance imaging (MRI) and dopamine transporter single‐photon emission computed tomography (DAT‐SPECT) in a case of organophosphate‐induced toxic parkinsonism. Fluid‐attenuated inversion recovery (FLAIR) images showed bilateral striatal hyperintensity in the acute phase, followed by reduction of ...
