AbstractOverexpression of epidermal growth factor receptor (EGFR) is closely associated with a poor prognosis in non-small cell lung cancer (NSCLC), thus making it a promising biomarker for NSCLC diagnosis. Here, we conjugated a single-chain antibody (scFv) targeting EGFR with Fe3O4/Au nanoparticles to form an EGFR-specific molecular MRI bioprobe (scFv@Fe3O4/Au) to better detect EGFR-positive NSCLC tumors in vivo. In vitro, we demonstrated that the EGFR-specific scFv could specifically deliver Fe3O4/Au to EGFR-positive NSCLC cells. In vivo experiments showed that the accumulation of scFv@Fe3O4/Au in tumor tissue was detect...

3T MEGA-PRESS study of N-acetyl aspartyl glutamate and N-acetyl aspartate in activated visual cortex
ConclusionThe MEGA-PRESS pulse sequence together with the spectral preprocessing techniques allowed to demonstrate that the concentrations of NAAG and NAA in the visual cortex remain constant during continuous visual stimulation within the margin of error. An increase in the lactate signal intensity signifies the activation of the anaerobic glycolysis in activated visual cortex. (Source: Magnetic Resonance Materials in Physics, Biology and Medicine)

Effects of low-dose oxygen administration on renal blood oxygenation level-dependent MRI in children with glomerulonephritis
DiscussionLow-dose oxygen administration affects the results of BOLD MRI. We suggest that understanding the fluctuations due to oxygen administration is useful in monitoring the disease activity of glomerulonephritis. (Source: Magnetic Resonance Materials in Physics, Biology and Medicine)

Comparative analysis of SINC-shaped and SLR pulses performance for contiguous multi-slice fast spin-echo imaging using metamaterial-based MRI
Discussion and conclusionSLR-based FSE together with the metadevice allowed to increase the slice selectivity while still being within the safe SAR limits. The “slice cross-talk” effects were conditioned by the number of echoes in the echo train, the repetition time, and T1 relaxation times. The approach was more beneficial for T1-weighted SLR-based FSE as compared to PD-weighted. The combination of the metadevice and SLR-based FSE offers a promising a lternative for MR investigations that require scanning in a “Low-SAR” regime such as those for children, pregnant women, and patients with implanted devices.

Motion correction of free-breathing magnetic resonance renography using model-driven registration
In this study, we investigate whether MDR can effectively correct the motion in free-breathing MR renography (MRR).Materials and methodsMDR was generalised to linear tracer-kinetic models and implemented using 2D or 3D free-form deformations (FFD) with multi-resolution and gradient descent optimization. MDR was evaluated using a kidney-mimicking digital reference object (DRO) and free-breathing patient data acquired at high temporal resolution in multi-slice 2D (5 patients) and 3D acquisitions (8 patients). Registration accuracy was assessed using comparison to ground truth DRO, calculating the Hausdorff distance (HD) betw...
