ABSTRACT
Objective To analyze the mammographic findings of ductal carcinoma in situ,and to improve DCIS diagnosis.Methods 1 58 cases of infiltrating ductal carcinomas,27 cases of DCIS and 14 cases of DCIS with microinvasion identified by postoperative pathological were collected,and their mammographic data were analyzed etrospectively.Results There were significantly more calci-fication and pure calcification in DCIS group than in IDC group(both P 0.05),both of them mostly showed granula and punctate calcification.There were statistically significant difference those two diseases for the distribution of calcification (P <0.05),the linearity and V-shaped segmental distribution occupies a relatively high percentage in DCIS while the cluster-like calcification occupies a relatively high percentage in IDC.Conclusion Pure calcification is mainly mammographic feature of DCIS.The characteristic of calcification is distribute along duct.
ABSTRACT
Objective To study the value of double contrast barium enema(DCBE),colonoscopy and spiral CT in examination of colonic disease.Methods 325 cases with colonic disease underwent DCBE,colonoscope and CT examinations.The detecting rates and the accurate rates in localizing the lesions were compared among these three examinations.Results The detecting rate of lesions by DCBE,colonoscope and CT were 91.1,89.8 and 64.6,respectively,there was no statistical difference between the former two,but there was difference between the former and CT(P
ABSTRACT
Objective To evaluate the value of breast molybdenum target radiography in evaluating the enlarged axillary lymph nodes in breast diseases.Methods 79 patients underwent breast molybdenum target radiography,including conventional laxial and oblique projection. Some of them were examine furtheremore in compress projection in axillary fossa. The X-ray findings were analysis. And radiologic-pathologic correlation were carried out.Results There were 46 cases of brease carcinoma, 20 cases of hyperplasia,7cases of fibroadenoma,2 cases of plasmacytic mammitis,2cases of lipoma and 2 cases of papilloma in 79 patients. In the 33 cases of breast benign lesion , the enlarged axillary lymph nodes were seen bilaterally in 12 cases, sum was 1 to 5 in each case, smaller than 2 cm in diameter in 31 cases and uneven density in 13 cases were showed. In the 46 cases of brease carcinoma, the enlarged lymph nodes were seen laterally in 43cases, sum was 1 to 4 in each cases, larger than 2 cm in diameter was showed in 17 cases, and all were even density. There were statistical differences in number, diameter and density of enlarged lymph nodes between two groups. Conclusion The enlarged axillary lymph nodes are of different X-ray features in breast benign lesion and malignant lesion,it is helpful in differential diagnosis of breast diseases.
ABSTRACT
Objective To study the relationship between X-ray features and pathologic infiltration of early gastric cancer.Methods 19 cases of early gastric cancer were analyzed, which were proved by pneumobarium double-contrast examination, operation and pathology. Results There were 9 cases of mucosa cancer and 10 cases of submucosa cancer in 19 patients of early gastric cancer certified by operation. The main X-ray features of mucosa cancer were: a lessened flexibility of local wall, indistinct outline, small trivialities became small nodes and small ditches became indistinct, they looked like pomegranate seeds. The main X-ray features of submucosa cancer were: the local wall was stiff, the density was high, there were small filling defects and small irregular niches, the rugae in the zone involved by the tumour became stiff, large even disappear, small trivialities and small ditches were destroyed. The X-ray findings of early gastric cancer had functional changes, abnormal contraction, more liquid in stomach.Conclusion Pneumobarium double-contrast examination is a voluable method for the diagnosis of early gastric cancer.
ABSTRACT
Objective To investigate the value of galactography in the diagnosis with nipple discharge.Methods 40 cases of galactography with nipple discharge proved by clinic and pathology were analyzed retrospectively.Results There were normal ducts in 7 cases, simple duct dilatation in 17 cases, breast duct dilatation accompanied chronic mastitis in 4 cases, breast duct dilatation accompanied hyperplasia in 2 cases, intraductal papilloma in 8 cases, ductal carcinoma in 1 case and abscess of the breast in 1 case.Conclusion Breast galactography plays important roles in diagnosis and differentiation of the breast disease with nipple discharge, and provides significant information for clinical department.
ABSTRACT
Objective To improve the diagnosis of multiple tuberculosis of bone and joints by analyzing its radiologic findings respectively .Methods 5 cases with multiple tuberculosis of bone and joints were all proved by pathology of them, there were 1 male and 4 female, the age ranged from 15 to 56 years old. X-ray films were all taken in 5 cases. Vertebral canal iodolography was performed in 1 case, 2 cases were undergone biopsy, and operation was done in 3 cases.Results Multiple bones in 5 cases were involved, including 3～5 bones. Of all cases, long bone and short bone were involved together in 3 cases, plat bone and vertebra were involved together in 1 case, long bone, plat bone and vertebra were simultaneously involved in 1 case. And 3 cases involved long bone and short bone simultaneously had pathosis in unilateral limbs, 2 cases involved plat bone had pathosis in bilateral. X-ray plain films demonstrated osteolytic destruction with slight sclerosis at the margin of partial destructive areas, which were round, oval or irregularity. There were soft tissue masses around the involved bones.Conclusion The multiple tuberculosis of bone and joint is of some clinic symptoms and X-ray features, but the confirmed diagnosis of which is entertained by biopsy and pathology.
