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 ...
129 Xe MRI has largely begun to replace 3 He gas MRI, a very similar technology that uses hyperpolarized 3 He molecules instead of 129 Xe. Grossman et al. began human clinical trials for 3 He MRI in 1996. 3 He was originally touted as the better gas for hyperpolarized gas MRI because it is more polarizable and has no effects on the body.

A lung nodule or pulmonary nodule is a relatively small focal density in the lung. A solitary pulmonary nodule ( SPN ) or coin lesion , [ 1 ] is a mass in the lung smaller than three centimeters in diameter.
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.
Percussion is performed in a systematic matter, from the upper chest to the lower ribs, and resonance is compared between the left and right sides of the chest. This is done from the front and back of the thorax. [14] Percussion over different body tissues results in five common "notes". [14] Resonance: Loud and low pitched. Normal lung sound. [15]
Most importantly, using interventional imaging in video-assisted thoracoscopic surgery can substitute for the loss of tactile sensing. This approach also delivers the potential to spare healthy lung tissue by knowing the exact position of the nodule which increases the quality of life for the patient after the operation.

Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...
A lobectomy is the surgical removal of one of the five lung lobes (right upper, right middle, right lower, left upper and left lower lobes). [24] Lobectomies are the most common type of lung surgery and the standard operation for most NSCLC patients. [25] Though specific surgical techniques vary for each lobe, the general workflow is identical.
