ABSTRACT
Objective To analyze the mammographic features and pathological characteristics among different molecular subtypes of breast cancer.Methods The results of 210 cases breast cancer identified by postoperative pathology were collected and classified to three groups;Luminal,HER-2(+)and TNBC(triple negative breast cancer)by molecular subtypes.Three groups'mammograph-ic features and pathological characteristics were compared.Results 210 cases included 147 Luminal cases,30 HER-2 (+)cases and 33 TNBC cases.There were statistically significant difference between tumor grading and lymph node metastasis (P 0.05).The mammographic features of Luminal molecules subtypes showed more mass with burr,HER-2(+)molecules subtypes showed no fixed features but more calcification incidence than other groups,TNBC molecules subtypes showed merely mass with clear margin and less calcification.Conclusion The mammographic fea-tures and pathological characteristics of different molecular subtypes of breast cancer are significant differences.
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 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.
