Non-invasive MR assessment of the microstructure and microcirculation in regional lymph nodes for rectal cancer: a study of intravoxel incoherent motion imaging

Cancer Imaging, 2019
Background The aim of this study is to evaluate the microstructure and microcirculation of regional lymph nodes (LNs) in rectal cancer by using non-invasive intravoxel incoherent motion MRI (IVIM-MRI), and to distinguish metastatic from non-metastatic ...

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).
