Abstract
Lung cancer is the leading cause of cancer death worldwide. Only an accurate assessment of the stage of lung cancer can determine the most appropriate treatment. Due to the physiological activities of lung and mediastinum, MRI has not been routinely used in clinical staging, diagnosis and treatment of lung cancer (1,2). With the emergence of ultra-low dose CT (ULDCT) and low-dose CT (LDCT), the radiation dose of CT used for screening pulmonary nodules is gradually reduced (3). However, benign and malignant pulmonary lesions sometimes have similar characteristics on CT. Pet-CT is often needed for diagnosis or puncture biopsy (4,5). Therefore, thoracic MRI assisted LDCT to evaluate the benign and malignant pulmonary nodules was born (3). In this review, we will explore the use of thoracic MR imaging to assist LDCT in the assessment of benign and malignant pulmonary lesions and the stage of lung cancer.
