Whole-body ferromagnetic detector systems in clinical MRI.

[Whole-body ferromagnetic detector systems in clinical MRI]. Radiologe. 2015 Aug 7; Authors: Güttler FV, Heinrich A, Teichgräber UK Abstract CLINICAL/METHODICAL ISSUE: In spite of technical and organizational measures, ferromagnetic objects still find their way into the magnetic resonance imaging (MRI) room and can cause severe injuries. STANDARD RADIOLOGICAL METHODS: A detailed patient education and MRI safety training for personnel are necessary to avoid MRI incidents with ferromagnetic objects. METHODICAL INNOVATIONS: Whole body ferromagnetic detection systems should increase patient safety and minimize risks for personnel and MRI equipment in the clinical routine. PERFORMANCE: In a clinical MRI setting, a screener system used for outpatients and inpatients (n = 400) identified unknown ferrous objects in 2 % of the cases. In two of these cases patients were found to be in possession of unknown foreign ferrous objects. Furthermore, a door guard system only used for outpatients (n = 2500) detected unknown ferromagnetic objects in 0.3 % of the cases. ACHIEVEMENTS: The number of ferrous objects that are unknowingly brought into the scanner room can be reduced with a whole body ferromagnetic detection system. For an optimal benefit of the system a ferrous-free environment and perfectly ferrous-free clothing for the medical personnel are necessary. In the clinical routine, the benefit o...

Conclusion: The development of LRSS pneumatization affects the removal rate of CS tumors in PAs. Preoperative analysis of LRSS development should be considered when planning EES against PA with CS invasion. PMID: 31819816 [PubMed]

We describe an extremely rare case of SFT in the left preauricular region. The tumor lesion had gradually grown without pain or facial paralysis. Magnetic resonance imaging scan showed a circumscribed mass with high signal intensity on Gd-DTPA-enhanced T1-weighted images measuring approximately 3.0 cm in diameter. The tumor lesion was excised completely. Histological examination of the surgical specimen revealed proliferation of spindle tumor cells with a patternless pattern. Various amounts of collagen bundles intervened in the spindle tumor cells. The cellular atypia of the tumor cells was weak. Immunohistochemical studi...

Publication date: Available online 11 December 2019Source: NeuroImageAuthor(s): Kenneth Wengler, Xiang He, Anissa Abi-Dargham, Guillermo HorgaAbstractNeuromelanin-sensitive MRI (NM-MRI) provides a noninvasive measure of the content of neuromelanin (NM), a product of dopamine metabolism that accumulates with age in dopamine neurons of the substantia nigra (SN). NM-MRI has been validated as a measure of both dopamine neuron loss, with applications in neurodegenerative disease, and dopamine function, with applications in psychiatric disease. Furthermore, a voxelwise-analysis approach has been validated to resolve substructure...

Thomas Yeo, César Caballero-Gaudes, Dimitri Van De VilleAbstractThe impact of in-scanner motion on functional magnetic resonance imaging (fMRI) data has a notorious reputation in the neuroimaging community. State-of-the-art guidelines advise to scrub out excessively corrupted frames as assessed by a composite framewise displacement (FD) score, to regress out models of nuisance variables, and to include average FD as a covariate in group-level analys...

This study was approved by the institutional review board. Sixty patients diagnosed with cervical cancer by pathology were prospectively included. Female pelvic magnetic resonance imaging was performed using a 3 T magnetic resonance scanner; B1 and B2 images were obtained for evaluation. Two radiologists blinded to the scan parameters evaluated the images for signal loss in the background, spatial distortion, image ghosting, confidence in the lesion delineation, and overall image quality using a 5-point scoring system. The scores were compared using a paired Wilcoxon test. SI was measured in the B1 and B2 images for...

GravesAbstractAutomatic identification of brain lesions from magnetic resonance imaging (MRI) scans of stroke survivors would be a useful aid in patient diagnosis and treatment planning. It would also greatly facilitate the study of brain-behavior relationships by eliminating the laborious step of having a human expert manually segment the lesion on each brain scan. We propose a multi-modal multi-path convolutional neural network sys...

ConclusionsThis study provides information about Aβ plaque burden, tau tangle burden, and neurodegeneration in cognitively unimpaired persons at three levels of genetic risk for AD. Unimpaired APOE ϵ4 HMs can be studied before their 70s to evaluate the understanding of factors, processes, and interventions involved in the predisposition to and prevention of AD, and after their 70s, to discover factors, processes, and interventions involved in the resilience or resistance to and prevention of AD.

Ann Yeh, Brenda Banwell, Amit Bar-Or, Douglas L. Arnold, Canadian Pediatric Demyelinating Disease NetworkAbstractIn conventional non-quantitative magnetic resonance imaging, image contrast is consistent within images, but absolute intensity can vary arbitrarily between scans. For quantitative analysis of intensity data, images are typically normalized to a consistent reference. The most convenient reference is a tissue that is always present in th...

AbstractObjectiveTo assess interobserver reproducibility of different regions of interest (ROIs) on multi-parametric renal MRI using commercially available software.Materials and methodsHealthy volunteers (HV), patients with heart failure (HF) and renal transplant recipients (Tx) were recruited. Localiser scans, T1 mapping and pseudo-continuous arterial spin labelling (pCASL) were performed. HV and Tx also underwent diffusion-weighted imaging to allow calculation of apparent diffusion coefficient (ADC). For T1, pCASL and ADC, ROIs were drawn for whole kidney (WK), cortex (Cx), user-defined representative cortex (rep-Cx) an...
