Research progress on application of diffusion weighted imaging and introvoxel incoherent motion in the diagnosis of diabetic nephropathy

Linchuang shenzangbing zazhi, 2020
Diabetic nephropathy(DN)is one of main chronic microvascular complications of diabetes mellitus(DM).Previous early diagnosis of DN mainly relied on medical history,laboratory examination and renal biopsy,but laboratory examination was easily affected by ...

Empirical noise mapping guides optimal region‐of‐interest selection for accurate noise estimation in prostate DWI

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Signal‐to‐noise ratio (SNR) measurements are important for quality assurance, especially when quantitative MRI markers or new hardware are being developed or evaluated. Regions of low signal or assumed uniform signal are used for SNR estimation in a variety of MR image types, but this is unreliable due to spatial heterogeneity of ...

Self‐Supervised Deep Learning Framework for Rician Distribution Based Denoising and Modeling of Multi‐b Prostate Diffusion MRI

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 928-942, August 2026.
ABSTRACT Purpose Convolutional neural networks (CNNs) are evaluated for improved and accelerated denoising and Rician bias correction in multi‐b DW images with simultaneous signal modeling. Methods Prostate diffusion images from 46 individuals acquired at 20 linearly distributed b‐values (bmax=2000s/mm2) without averaging were used for self‐supervised ...

Real‐Time, Inline Quantitative MRI Enabled by Scanner‐Integrated Machine Learning: A Proof of Principle With NODDI

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 986-995, August 2026.
ABSTRACT Purpose The clinical feasibility and translation of many advanced quantitative MRI (qMRI) techniques are inhibited by their restriction to ‘research mode’, due to resource‐intensive, offline parameter estimation. This work aimed to achieve ‘clinical mode’ qMRI, by real‐time, inline parameter estimation with a trained neural network (NN) fully ...

Estimating the Sodium Content: A Case Series of Benign and Malignant Renal Tumours Using 23Na‐MRI at 3 T

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
23Na‐MRI at 3 T was applied to estimate TSC in patients with kidney tumours of different pathologies, which are indistinguishable on conventional imaging methods. The apparent TSC was significantly higher in renal oncocytomas (benign) compared to chromophobe renal cell carcinomas (malignant): 162 ± 58 mM vs. 71 ± 2 mM (p < 0.05).

Hyperpolarized MRI Detects Increased [1‐13C]Pyruvate Metabolism in Early Liver Regeneration

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Hyperpolarized [1‐13C]pyruvate MRI detected increased pyruvate‐to‐lactate and pyruvate‐to‐alanine exchange during early liver regeneration following 70% partial hepatectomy in rats. These findings support the use of hyperpolarized MRI for noninvasive assessment of regenerative metabolism.

In Vivo Assessment of Placental Structure and Perfusion in Late‐Gestation Pregnancies and Their Association With Fetal Growth

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Multiparametric 3T MRI combining structural imaging and pCASL quantified placental structure and perfusion in late gestation. Mean placental‐blood‐flow (PBF) and arterial‐transit‐time (ATT) values were higher than previously reported at earlier gestational‐ages (GA).
