Article Abstract
Purpose: To harmonize the use of color for MR relaxometry maps and therefore recommend the use of specific color-maps for representing , , and maps and their inverses.
Methods: Perceptually linearized color-maps were chosen to have similar color settings as those proposed by Griswold et al. in 2018. A Delphi process, polling the opinion of a panel of 81 experts, was used to generate consensus on the suitability of these maps.
Results: Consensus was reached on the suitability of the logarithm-processed Lipari color-map for and the logarithm-processed Navia color-map for and . There was consensus on color bars being mandatory and on the use of a specific value indicating "invalidity." There was no consensus on whether the ranges should be fixed per anatomy.
Conclusion: The authors recommend the use of the logarithm-processed Lipari color-map for displaying quantitative maps and maps; likewise, the authors recommend the logarithm-processed Navia color-map for displaying , , , and maps. This work originated with the Quantitative MR Study Group of the International Society of Magnetic Resonance in Medicine (ISMRM); it has the approval of the Publication Committee and of the Board of the ISMRM.

Pulmonary T2* quantification of fetuses with congenital diaphragmatic hernia: a retrospective, case-controlled, MRI pilot study.
Pediatr Res

Department of Women and Children's Health, King's College London, London, United Kingdom.
Background: Advanced MRI techniques, motion-correction and T2*-relaxometry, may provide information regarding functional properties of pulmonary tissue. We assessed whether lung volumes and pulmonary T2* values in fetuses with congenital diaphragmatic hernia (CDH) were lower than controls and differed between survivors and non-survivors.
Methods: Women with uncomplicated pregnancies (controls) and those with a CDH had a fetal MRI on a 1.
Utility of MR fingerprinting in differentiating epileptogenic from non-epileptogenic cortical malformations.

Objective: This study investigates the potential of magnetic resonance fingerprinting (MRF) as a non-invasive method to differentiate epileptogenic from non-epileptogenic cortical malformations.
Methods: Sixty-nine subjects were included: four patients with complex cortical malformations who underwent detailed pre-surgical assessments including Stereo-EEG (SEEG) and/or subsequent surgery, 17 with histopathologically confirmed FCD II, and 48 healthy controls (HC). All subjects underwent a whole-brain 3 T MRF acquisition, the reconstruction of which generated T1 and T2 relaxometry maps.
Storage and Ripening Monitoring of Pecorino Cheese Through 2D H-NMR Relaxation and ANOVA Simultaneous Component Analysis (ASCA): A Comparison with DSC and ATR-FTIR Characterization.

In food processing, non-destructive and non-invasive characterization is a powerful tool for monitoring processes and controlling quality. Cheeses consist of a large variety of products whose nutritional and sensory properties depend on the source materials, cheesemaking procedures, and biochemical transformations occurring during maturation and storage. In this study, proton magnetic resonance relaxation time correlation maps (2D H-NMR T-T) are used to investigate the effect of the ripening degree on Pecorino cheese and evaluate its evolution during storage in a refrigerator under vacuum-packaging conditions.

Objectives: To evaluate the feasibility of a prototype MRF sequence in an automated pipeline for T2 extraction of knee cartilage, and to compare it to the same procedure with a conventional T2 mapping sequence.
Materials And Methods: Seventeen healthy volunteers and twenty patients with a focal cartilage damage ICRS grade I-III diagnosed via morphological MRI underwent knee MRI examination, including a prototype MRF sequence, a conventional multi-slice multi-echo (MSME) T2 mapping sequence and double-echo steady-state sequence (DESS). Automated cartilage segmentation with a subsequent automated pipeline for T2 extraction from both T2 maps was performed.

Background: SyntheticMR has the capability of generating quantitative relaxometry maps and synthetic contrast-weighted MRI images in rapid acquisition times. Recently, it has gained attention in the diagnostic community, however, no studies have investigated its feasibility on the MR-Simulation or MR-Linac systems, especially as part of the head and neck adaptive radiation oncology workflow.
Purpose: Demonstrating its feasibility will facilitate rapid quantitative biomarker extraction, which can be leveraged to guide adaptive radiation therapy decision making.
