Comparative Study
Magnetic resonance scanning in cystic fibrosis: comparison with computed tomography.
Comparison has been made between two different spin-echo sequence MR scans and CT scans of the lungs in 17 patients with cystic fibrosis. Scans were assessed for bronchial dilation, bronchial wall thickening and mucus plugging. ⋯ Stronger background lung signal and less artefact was seen on TE7 ms scans compared with TE30 ms scans. MR is a developing technology that does not involve ionizing radiation which, with further refinement, may prove to be useful in imaging lung pathology in cystic fibrosis.
