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).

Enhancing pancreatic adenocarcinoma delineation in diffusion derived intravoxel incoherent motion f-maps through automatic vessel and duct segmentation

, 2011
Diffusion-based intravoxel incoherent motion imaging has recently gained interest as a method to detect and characterize pancreatic lesions, especially as it could provide a radiation- and contrast agent-free alternative to existing diagnostic methods ...

Intravoxel incoherent motion imaging for assessment of bone marrow infiltration of monoclonal plasma cell diseases

, 2013
Modern imaging techniques have demonstrated that monoclonal plasma cell diseases infiltrate the bone marrow in a diffuse, focal, mixed pattern. While focal lesions can be easily counted and measured, the diffuse lesions of the infiltration are hard to ...
