Hyperpolarized 129 Xe gas magnetic resonance imaging is a medical imaging technique used to visualize the anatomy and physiology of body regions that are difficult to image with standard proton MRI. In particular, the lung, which lacks substantial density of protons, is particularly useful to be visualized with 129 Xe gas MRI. This technique ...
Hyperpolarized gas MRI, also known as hyperpolarized helium-3 MRI or HPHe-3 MRI, is a medical imaging technique that uses hyperpolarized gases to improve the sensitivity and spatial resolution of magnetic resonance imaging (MRI). This technique has many potential applications in medicine, including the imaging of the lungs and other areas of ...
DURHAM, NC and LONDON, Jan. 28, 2025 (GLOBE NEWSWIRE) -- Polarean Imaging plc (AIM: POLX) (“Polarean” or the “Company”), a commercial-stage leader in advanced medical imaging focused on functional Magnetic Resonance Imaging ("MRI") of the lungs, announces a strategic collaboration with SimonMed Imaging, one of the largest outpatient medical imaging providers in the United States, to ...
Zhou has experience in magnetic resonance imaging (MRI) and spectroscopy, focusing on ultrasensitive MRI instruments, techniques, and biosensors for medical imaging. [3] He developed the clinically approved Human Lung Gas MRI Instrument, which was applied in the Jinyintan Hospital (Wuhan, China) and the Tongji Hospital for evaluating pulmonary injuries caused by viruses in discharged patients.

Traditional MRI generates poor images of lung tissue because there are fewer water molecules with protons that can be excited by the magnetic field. Using hyperpolarized gas an MRI scan can identify ventilation defects in the lungs. Before the scan, a patient is asked to inhale hyperpolarized xenon mixed with a buffer gas of helium or nitrogen ...
MIP is used for the detection of lung nodules in lung cancer screening programs which use computed tomography scans. MIP enhances the 3D nature of these nodules, making them stand out from pulmonary bronchi and vasculature.
Chest x-ray of infant showing CPAM in the left lung causing a mediastinal shift towards the right. The cysts appear as bubbles in the left lung. Congenital pulmonary airway malformation (CPAM) is a rare disease in which the lung airways develop abnormally in the fetus. This leads to infants having pockets of air and cystic masses in their lungs.
