Objective To make a futher understanding of the CT features of primary carcinoma of vagina and to explore the clinical value of CT diagnosis of it.Methods Sixteen cases of primary cacinoma of vagina with clinical and CT data confirmed by pathology were analyzed retrospectively. The CT findings were observed in a double blind method by three experienced radiologists together and formed a consensus interpretation. Results The accurate rate of CT diagnosis for primary carcinoma of vagina was 81.3% in the 16 cases. There were 2 stage I, 6 stage II, 4 stage III and 4 stage IV lesions which were diagnosed by CT. The numbers of cases of the elevated type, ulcerative type and infiltrative type were 11, 3, and 2,respectively. The transcatherter internal pudendal arterial chemoembolization were successfully performed in 2 patients with vaginal carcinoma. Conclusion CT is not only a non-invasive method of detecting primary carcinoma of vagina,but also play an important role in differentiating the clinlcal phase and type of it. In more advanced stages of vaginal carcinoma, interventional therapy is chosen as the useful treatment to avoid exenterative surgery, preserve anatomy and function.

Oleic acid was injected intravenously into 29 dogs to induce the experimental 'Respiratory Distress Syndrome'. The chest x-ray manifestations of RDS were observed and analyzed. Correlating the x-ray findings with the findings of patho-anatomical examination, which was done on the killed dogs, the authors tried to investigate the pathogenesis of RDS. Meanwhile the diameter of the first branch of either inferior pulmonary artery was measured to determine the variations of the contractions of the pulmonary arteries.Finally the therapeutic effect of anisodamine and dexamethasone was compared. It seemed that the effect of the former was better than that of the latter from our preliminary trial.

This paper discusses the conception of multimedia courseware in the teaching of medical imaging technology, and meaning, features and requirements. It is concluded multimedia courseware can play an important role in the teaching of medical imaging technology. Also, some problems existing in the application are analysed in this article.

Objective To assess the examinational value of tissue equalization (TE)technique in DR thoracolumbar vertebral body photography. Methods 48 cases were reformed using the conventional DR method in the thoracolumbar vertebral body photography,compared with the TE technique in DR thoracolumbar vertebral body photography. Results The details in different thickness area of body could be revealed clearly in the same image produced by TE technique. The visualization of image details could be obviously improved by using the TE technique. Conclusion It is important to apply the TE technique in DR thoracolumbar vertebral body photography.
