Objective To discuss the correlation between MSCT morphological index of emphysema and pulmonary function test (PFT) indexes. Methods We randomly selected 33 cases with chronic obstructive pulmonary disease (COPD),and conducted CT and PFT in a week. The whole lung was scanned by MSCT at the end of deep aspiration,and the post-processing workstation was used for quantitative determination of a total of 12 morphological indexes,including the density of lung, pulmonary diameter line,lung volume,and etc,then their correlation with lung function index was analyzed.Results FEV1.0%had correlation with upper right lung density ( =0.391, =0.391), lower right lung density ( =0.465, =0.038),the mean lung density ( =0.576,=0.576), and total lung capacity (=0.471, =0.471),upper right lung volume ( =0.413, =0.049) . FEV1.0/FVC had correlation with left lower lung density ( =0.392, =0.024), the mean lung density ( =0.703, = 0.000), total lung transverse diameter ( = 0.521, = 0.521), upper right lung maximum transverse diameter ( =0.627, =0.627), and total lung capacity ( =0.549, =0.549) correlation. FVC had correlation with upper right lung maximum transverse diameter ( = 0.378, = 0.378), characterized by maximum transverse diameter (=0.349, =0.037) . TLC had correlation with mean lung density (=0.523,=0.523), upper right lung maximum transverse diameter ( =0.454, =0.454), and total lung capacity (= 0.001), the right lung volume ( = 0.492, = 0.492) . Conclusion MSCT lung morphology quantitative indicators have good clinical application value in the diagnosis and assessment of emphysema patients.

With the increasingly strengthening of economic globalization and higher education internationalization,medical imageology as an important intersecting science in life sciences has more and more international communion and cooperation.In China many hospitals and medical colleges require large quantities of medical imageology professionals,and it is very necessary and important to develop the bilingual education in medical imageology,though a series of problems appear in the process.

The developing situation of "big image" makes the medical imaging become an increasingly huge and complicated system.It offers higher request to the medical imaging teaching.The internship of last term is always influenced by attending the graduate student's entrance examination and looking for job,the effect of teaching can't be assured,and it especially important to do well in field trip,thus it can reduce or avoid the phenomenon of "practice after graduate".

With development of medical imaging,traditional picture has been replaced by digital information.To apply information-based education to medical imaging and enhance the teaching quality,the article explored the teaching methods of information-based education.
