Purpose

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.

Condition	Intervention	Phase
Asthma	Device: magnetic resonance imaging (MRI) of the thorax	Phase 1


Study Type:	Interventional
Study Design:	Allocation: Non-Randomized Intervention Model: Single Group Assignment Masking: None (Open Label) Primary Purpose: Diagnostic
Official Title:	MR Perfusion Imaging in Asthmatic Patients

Further study details as provided by University Health Network, Toronto:

Primary Outcome Measures:

The correlation of MR lung perfusion analysis with computed tomography (CT) findings and pulmonary function tests


Estimated Enrollment:	80
Study Start Date:	September 2005
Estimated Study Completion Date:	December 2005

Detailed Description:

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.
