COPD Clinical Trial
Official title:
Non-contrast-enhanced Perfusion Imaging of the Lung Using Fourier Decomposition Magnetic Resonance Imaging (FD MRI): Assessment of Feasibility in Patients With COPD in Correlation With Perfusion Scintigraphy, SPECT/CT and DCE MRI
In the recent years a novel method for functional lung imaging called Fourier decomposition MRI (FD MRI) has been introduced that allows for simultaneous assessment of regional lung perfusion and ventilation-related information without exposure to ionizing radiation or administration of intravenous or inhalational contrast agent. In this project, the investigators plan to investigate whether Fourier decomposition (FD) MRI is able to provide similar clinical information on regional lung perfusion as the standard methods SPECT/CT and DCE MRI in patients with COPD.
In the recent years a novel method for functional lung imaging called Fourier decomposition
MRI (FD MRI) has been introduced that allows for simultaneous assessment of regional lung
perfusion and ventilation-related information without exposure to ionizing radiation or
administration of intravenous or inhalational contrast agent.
In this project, the investigators plan to investigate whether Fourier decomposition (FD) MRI
is able to provide similar clinical information on regional lung perfusion as the standard
methods SPECT/CT and DCE MRI in patients with COPD. As MRI in patients with COPD is
particularly challenging due to the rarefication of lung parenchyma, the FD MRI technique
will be combined with an ultra-fast Steady-State Free Precession (ufSSFP) acquisition method
for improved signal efficiency. The investigators ultimate goal is to provide a mean to
predict and monitor the outcome of different therapies, such as medication, valves and
surgery in COPD patients without requiring ionizing radiation or administration of contrast
agents.
In the framework of this study, 30 patients with COPD will be enrolled prospectively. The
study participants will be recruited by the clinic for thoracic surgery at the University
Hospital Basel among all patients undergoing lung perfusion scintigraphy with SPECT/CT for
surgery planning. Each participant will undergo one MRI examination of 30 min containing
non-contrast-enhanced (FD MRI) and contrast-enhanced (DCE MRI) imaging studies of regional
lung perfusion.
