Parents and family background cast important influence on children's attachment style. Studies have consistently showed positive relations between maternal sensitivity and infant attachment security. Warm and harmonious family was also found to be an important factor. On the contrary, parents' poor marital status and high level of stress in family would result in insecure attachment style in children.

Magnetic resonance imaging (MRI),a commonly used imaging technique,has been extensively investigated in lung cancer diagnosis and staging.Many studies have demonstrated that MRI can be used for the differential diagnosis of benign and malignant pulmonary nodules and for the screening of lung cancer; it also has important value in TNM staging of non-small cell lung cancer (NSCLC),with equivalent sensitivity and specificity to 18F-fluorodeoxyglucose (18F-FDG) PET-CT,which suggests that MRI can be used as an alternative imaging modality in noninvasive diagnosis and staging of NSCLC.
