[Abstract] Objective: To investigate the expression of non-enhanced magnetic resonance angiography (MRA) in central lung cancer and its relationship with mediastinal vessels.Materials and Methods: Sixty patients who did not receive chemoradiotherapy and any other adjuvant anti-tumor therapy were enrolled in the study. The patients who underwent surgical pathology or bronchoscopy biopsy were included in the study. All patients underwent two-dimensional free-breathing TrueFISP sequence before surgery. Two-dimensional breath-holding TrueFISP Sequence and 3D respiration trigger SPACE sequence check. Image quality evaluation of the three imaging sequences included quantitative evaluation and qualitative evaluation. Finally, the morphological types of tumor-vessel relationships were classified into 1—6 types, and the type of morphological relationship between tumors and major blood vessels in each non-enhanced MRA method was evaluated and recorded.Results: There was no significant difference in CNR for the three non-enhanced MRA techniques. The VTR (P=0.000) and image quality (P=0.000) scores of the two TrueFISP techniques were higher than those of the SPACE technique. Three MRA techniques and enhanced MDCT were consistent in the evaluation of lung cancer and vascular relationship.Conclusions: Both TrueFISP and SPACE techniques can satisfactorily display the hilar and mediastinal vessels and accurately evaluate the relationship between lung cancer and large vessels, and have good consistency with enhanced MDCT results. The image quality and VTR of the TrueFISP sequence are slightly better than the SPACE sequence. In the evaluation of the relationship between lung cancer and the hilar and mediastinal vessels, the consistency with the enhanced MDCT results is slightly better.
