Physiological Lung Testing in the MRI to Find Damage from Military Deployments

Our military veterans who served overseas in the middle east often come home with scars both seen and unseen. For some vets, unfortunately, these scars can take the form of lung damage sustained due to sandstorms, burn pits, and other high toxicity situations apparent in wartime in a symptom known as War Lung Injury (WLI). North Carolinian researchers from Duke University and the Durham VA Med Center utilized pulmonary transducers developed for the MRI to measure lung capacity during normal use.

Diaphragm Imaging Comparison in Healthy and Sick Subjects

In the interest of advancing new medical treatments, a study was taken on a novel means to image human diaphragms called Tissue Doppler Imaging. The study measured the effectiveness of this new imaging system by comparing diaphragm action with healthy and ill patients in a subject group. A magnetic resonance compatible pneumatograph from BIOPAC helped record Pdi during the experiment.

Measuring Blood Flow in the MRI to Monitor Alzheimer’s

Magnetic Resonance Imagers are a diagnostician’s best tool to view transdermal functions in the human body. To the extreme benefit of scientists everywhere, MRIs have become slightly cheaper as technology improves, and they are put to use in novel means to help us understand more about how the human body works. Here, cerebral hemodynamics (blood flow in the brain) were measured with an MRI in a study of Alzheimer’s Disease, and particularly how several indicators of flow compared between patients with the disease. A BIOPAC MP-Series Data Acquisition unit connected to a wireless BioNomadix Pulse Transducer recorded photoplethysmyography during the study.
