The human lung and its functions are extremely sensitive to gravity; however, the conventional high-field magnets used for most laser-polarized (3)He MRI of the human lung restrict subjects to lying horizontally. Imaging of human lungs using inhaled laser-polarized (3)He gas is demonstrated in an open-access very-low-magnetic-field (<5 mT) MRI instrument. This prototype device employs a simple,...

UNLABELLED ICMA, a software framework to create 3D finite element models of the left ventricle from cardiac ultrasound or magnetic resonance imaging (MRI) data, has been made available as an open-source code. The framework is hardware vendor independent and uses speckle tracking (endocardial border detection) on ultrasound (MRI) imaging data in the form of DICOM. Standard American Heart Associa...

Abstract Background The diagnosis of newly detected liver nodules in patients with colorectal cancer (CRC) is crucial for determining prognosis and treatment. Accurate identification benign can help avoid unnecessary therapy. aim our study was to retrospectively review CRC who underwent resection institution. Methods We went over all a history CRC, from January 2012 December 2019 specifically f...

Real-time magnetic resonance imaging (RT-MRI) of human speech production is enabling significant advances in science, linguistics, bio-inspired technology development, and clinical applications. Easy access to RT-MRI however limited, comprehensive datasets with broad are needed catalyze research across numerous domains. The the rapidly moving articulators dynamic airway shaping during demands h...

The objective of the present study is to make a comparison between various free and open-source software used for medical image processing, such as 3D Slicer (version 4.11), ITK-Snap 3.8), Invesalius 3.1) in its application calculation solitary fibrous tumor volumes. Knowing size, shape, volume mesothelioma decisive clinical decision-making by health personnel when performing surgery; currently...

introduction the use of cut-outs in electron applicators make changes on output, isodose, and percentage depth dose (pdd) curves. these changes and electron beam dose distribution in the form of three-dimensional (3d) can be measured by gel dosimeters. materials and methods dosimetry was performed with and without a square shield (6×6 cm2 field). the energies were 4, 9, and 16 mev and phantom w...

PURPOSE To assess if 3T MRI can be further improved by adding surface coil imaging, in the context of detection and characterization of cerebral lesions in patients with drug-resistant epilepsy. METHODS Twenty five patients with drug-resistant epilepsy undergoing evaluation for epilepsy surgery were examined with high resolution 3T MRI. The patients were MRI-negative (n = 15), or had unclear ...

background & aim: conjoined nerve root is defined as two adjacent nerve roots that share a common dural envelope at some points during their course from the thecal sac. this study reports our experience of conjoined roots involving three cases in dakar. methods & materials/patients: this is a consecutive study from 2013 to 2015 involving patients supported for disc herniation and who have prese...
