space Low-Field (64 mT) Portable MRI for Rapid Point-of-Care Diagnosis of Dissemination in Space in Patients Presenting with Optic Neuritis [CLINICAL PRACTICE] By www.ajnr.org Published On :: 2024-11-07T15:14:12-08:00 BACKGROUND AND PURPOSE: Low-field 64 mT portable brain MRI has recently shown diagnostic promise for MS. This study aimed to evaluate the utility of portable MRI (pMRI) in assessing dissemination in space (DIS) in patients presenting with optic neuritis and determine whether deploying pMRI in the MS clinic can shorten the time from symptom onset to MRI. MATERIALS AND METHODS: Newly diagnosed patients with optic neuritis referred to a tertiary academic MS center from July 2022 to January 2024 underwent both point-of-care pMRI and subsequent 3T conventional MRI (cMRI). Images were evaluated for periventricular (PV), juxtacortical (JC), and infratentorial (IT) lesions. DIS was determined on brain MRI per 2017 McDonald criteria. Test characteristics were computed by using cMRI as the reference. Interrater and intermodality agreement between pMRI and cMRI were evaluated by using the Cohen . Time from symptom onset to pMRI and cMRI during the study period was compared with the preceding 1.5 years before pMRI implementation by using Kruskal-Wallis with post hoc Dunn tests. RESULTS: Twenty patients (median age: 32.5 years [interquartile range {IQR}, 28–40]; 80% women) were included, of whom 9 (45%) and 5 (25%) had DIS on cMRI and pMRI, respectively. Median time interval between pMRI and cMRI was 7 days (IQR, 3.5–12.5). Interrater agreement was very good for PV (95%, = 0.89), and good for JC and IT lesions (90%, = 0.69 for both). Intermodality agreement was good for PV (90%, = 0.80) and JC (85%, = 0.63), and moderate for IT lesions (75%, = 0.42) and DIS (80%, = 0.58). pMRI had a sensitivity of 56% and specificity of 100% for DIS. The median time from symptom onset to pMRI was significantly shorter (8.5 days [IQR 7–12]) compared with the interval to cMRI before pMRI deployment (21 days [IQR 8–49], n = 50) and after pMRI deployment (15 days [IQR 12–29], n = 30) (both P < .01). Time from symptom onset to cMRI in those periods was not significantly different (P = .29). CONCLUSIONS: In patients with optic neuritis, pMRI exhibited moderate concordance, moderate sensitivity, and high specificity for DIS compared with cMRI. Its integration into the MS clinic reduced the time from symptom onset to MRI. Further studies are warranted to evaluate the role of pMRI in expediting early MS diagnosis and as an imaging tool in resource-limited settings. Full Article
space Deep Learning-Based Reconstruction of 3D T1 SPACE Vessel Wall Imaging Provides Improved Image Quality with Reduced Scan Times: A Preliminary Study [ARTIFICIAL INTELLIGENCE] By www.ajnr.org Published On :: 2024-11-07T15:14:12-08:00 BACKGROUND AND PURPOSE: Intracranial vessel wall imaging is technically challenging to implement, given the simultaneous requirements of high spatial resolution, excellent blood and CSF signal suppression, and clinically acceptable gradient times. Herein, we present our preliminary findings on the evaluation of a deep learning–optimized sequence using T1-weighted imaging. MATERIALS AND METHODS: Clinical and optimized deep learning–based image reconstruction T1 3D Sampling Perfection with Application optimized Contrast using different flip angle Evolution (SPACE) were evaluated, comparing noncontrast sequences in 10 healthy controls and postcontrast sequences in 5 consecutive patients. Images were reviewed on a Likert-like scale by 4 fellowship-trained neuroradiologists. Scores (range, 1–4) were separately assigned for 11 vessel segments in terms of vessel wall and lumen delineation. Additionally, images were evaluated in terms of overall background noise, image sharpness, and homogeneous CSF signal. Segment-wise scores were compared using paired samples t tests. RESULTS: The scan time for the clinical and deep learning–based image reconstruction sequences were 7:26 minutes and 5:23 minutes respectively. Deep learning–based image reconstruction images showed consistently higher wall signal and lumen visualization scores, with the differences being statistically significant in most vessel segments on both pre- and postcontrast images. Deep learning–based image reconstruction had lower background noise, higher image sharpness, and uniform CSF signal. Depiction of intracranial pathologies was better or similar on the deep learning–based image reconstruction. CONCLUSIONS: Our preliminary findings suggest that deep learning–based image reconstruction–optimized intracranial vessel wall imaging sequences may be helpful in achieving shorter gradient times with improved vessel wall visualization and overall image quality. These improvements may help with wider adoption of intracranial vessel wall imaging in clinical practice and should be further validated on a larger cohort. Full Article

space Factorio: Space Age review: a stellar expansion produces a masterful final form By www.rockpapershotgun.com Published On :: Tue, 05 Nov 2024 15:00:00 +0000 To say that Factorio: Space Age throws out the rulebook is an understatement. It'd be more fitting to say it's somehow automated the whole process: an inserter plucked out the rulebook from my brain and deposited it in hot magma, while a new rulebook was churned out in a nearby machine and plopped into my brain from the other side - only for that to be immediately plucked out and incinerated as well. With each new planet and each new phase, Space Age reinvents itself. I'm battling hyperbole here, but ah hell, I admit defeat. Factorio: Space Age is a masterpiece, the final form of perhaps the most well-crafted building game I'll ever play.

space The co-creator of magic puzzler Hidden Folks is making a sumptuous, spaced-out tower defender By www.rockpapershotgun.com Published On :: Fri, 08 Nov 2024 11:06:29 +0000 Could tower defence be the ultimate "it's Friday and I am here in body only" genre? I haven't really thought about it before, but Rift Riff's effusively laidback crowd control has me pondering those optimal moments in any tower defender when the incoming horde hits the flamer-MG triangle just right, and you can settle back comfortably into the role of clockwatcher. Rift Riff encourages this behaviour by being nice to look at. Created by a trio of developers including Hidden Folks designer Adriaan de Jongh, it's a world of spacey, sun-carved mountains, forests and monoliths. The towers resemble the sacred architecture of Monument Valley, and the colour scheme and general ambience remind me of Cocoon. There's a demo, if you fancy it.

space Warhammer 40,000: Space Marine 2 patch adds a new weapon, plus some tweaks for the existing arsenal By www.rockpapershotgun.com Published On :: Tue, 12 Nov 2024 15:08:03 +0000 "Where’s my Neo-Volkite pistol, Warhammer 40,000: Space Marine 2?" was my perhaps slightly ungrateful reaction upon booting the action game up after the previous patch. "I didn’t even know what a Neo-Volkite pistol was until five minutes ago, but now this whole game is trash until I get one!." As promised in the roadmap, the last big update added a whole new Operations map, complete with a gargantuan new pseudo-boss in the form of a hierophant bio-titan. It did not, however, give me my beloved pistol. It’s fine. It’s in now, along with a few, less Neo-Volkite updates to other weapons.
