Summary

This trial will study how aging affects the lungs by testing elderly subjects with MRI, lung function, and exercise tests.

Who is the study for?
This trial is for healthy older adults, both men and women aged 60-90, who have smoked less than half a pack of cigarettes in their lifetime. Participants must be able to hold their breath for 16 seconds, have a BMI between 18-30, and perform consistent lung function tests. They should understand the study and consent to participate.
What is being tested?
The trial involves using Hyperpolarized Helium-3 gas during an MRI scan to develop tools that can measure changes in the lungs as people age. It includes MRI scans along with lung function and exercise testing on stationary bicycles.
What are the potential side effects?
There are minimal side effects expected from this trial since it involves non-invasive imaging techniques like MRI scans with Hyperpolarized Helium-3 gas. However, some individuals may experience discomfort or claustrophobia inside the MRI machine.
