Although it has many advantages and clinical utility, most radiologists are unfamiliar with this technique because of its novelty. This review aims to (1) explain the basic principles of lung perfusion assessment using DCR, (2) discuss the advantages of DCR over other imaging modalities, and (3) review multiple specific clinical applications of DCR for pulmonary vascular diseases and compare them with other imaging modalities..

Koji Sagiyama, Masateru Kawakubo, Ryohei Funatsu, Takeshi Kamitani, Yuzo Yamasaki, Tomoyuki Hida, Yuko Matsuura, Yuriko Murayama, and Hidetake Yabuuchi, Detecting regional differences of lung motion by optical flow analysis combined with rapid cine MRI using compressed sensing, ISMRM & SMRT VIRTUAL CONFERENCE & EXHIBITION, 2020.08, [URL], The application of cine MRI to lung disease has been technically challenging. In this study, we exploited optical flow analysis combined with rapid acquisition of cine MRI using compressed sensing to detect differences in regional lung motion. The high spatial and temporal resolution and higher signal-to-noise ratio of cine MRI enabled optical flow analysis to visualize regional differences between five lung segments. It also differentiated between chest and diaphragm breathing patterns in volunteers. In the future, this non-invasive method could be applied to assess and follow lung diseases, such as interstitial pneumonia or chronic obstructive pulmonary disease..
