Magnetic Resonance (MR) in Asthmatic Patients
Asthma is a disease of small airways. Affected areas have reduced lung ventilation causing reflex vasoconstriction. MR perfusion imaging of the lungs is a sensitive method of imaging zonal lung perfusion.
|Study Design:||Allocation: Non-Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
|Official Title:||MR Perfusion Imaging in Asthmatic Patients|
- The correlation of MR lung perfusion analysis with computed tomography (CT) findings and pulmonary function tests
|Study Start Date:||September 2005|
|Estimated Study Completion Date:||December 2005|
A cohort of 70 Asthmatic Patients and 10 controls, both sets of subjects have HRCT, MRI/A of the Thorax, and Pulmonary Function Tests to correlate the degree of pulmonary dysfunction with findings on imaging tests.
