MRI scans could replace invasive heart tests

New research shows they can accurately measure pressures in the heart

A new study has shown that MRI scans can accurately measure pressures in the heart, which could replace the need for invasive heart tests.

The study, which was published in the journal JAMA Cardiology, involved more than 39,000 participants from the UK Biobank.

The researchers found that MRI scans were able to accurately measure pulmonary capillary wedge pressure (PCWP), which is a measure of the pressure in the heart's left atrium.

PCWP is an important measure of heart function, and it can be used to diagnose and manage heart failure.

The researchers say that their findings suggest that MRI scans could be used to replace invasive heart tests, such as right heart catheterization, which are currently used to measure PCWP.

This would be a significant advance, as MRI scans are less invasive and more widely available than right heart catheterization.
