Challenges of Using 3 T MR Systems and Whole-Body MRI for Lung Imaging

摘要: Ever since the clinical application of magnetic resonance (MR) imaging became an essential diagnostic tool, lung has been a challenging area. Although many physicists and radiologists tried to assess different diseases as well mediastinal cardiac by means MR during 1980s early 1990s, they could neither produce convincing image quality within reasonable examination time nor demonstrate that serve substitute for computed tomography (CT), pulmonary angiography, and/or nuclear medicine studies. However, improvement 1.5-tesla (T) system sequences, new techniques such parallel imaging, utilization more effective contrast media have continued late 1990s. These developments made it possible apply not only oncologic but also other diseases, morphological functional assessment various cardiopulmonary diseases. Moreover, these improvements continuing, resulting in gradual shifting use higher strength field (≥3 T) 2000s.
