ABSTRACT
Objective To evaluate the correlation of epicardial adipose tissue volume (EATV)with coronary plaques in patients with a coronary artery calcium score of zero.Methods 183 patients with a coronary artery calcium score of zero were selected.They were divided into plaque group and control group according to the findings of CT coronary angiography.Independent t test was used to analyze the difference of EATV between two groups.Results ①EATV was significant higher in plaque group than that in control group (P 0.05), while it was significant higher in plaque group than that in control group for male individuals (P <0.05).③EATV was significant higher in plaque group than that in control group for the individuals with age< 50 years (P <0.05 ),meanwhile it was significant higher in plaque group than that in control group in age≥50 years(P <0.05).Conclusion EATV is correlated with coronary plaques in male patients with a coronary artery calcium score of zero while there is no correlation with female patients.EATV is correlated with coronary plaques in different age patients with a coronary artery calcium score of zero.
ABSTRACT
Objective To evaluate the diagnostic value of spiral CT and all kinds of 3D reconstruction in pulmonary tuberculosis .Methods 145 cases of pulmonary tuberculosis confirmed by clinical study and histopathology were analyzed retrospectively. All cases weregiven to helical scan and different cases were given to different 3D reconstruction (CTVE, MPR and CPR) .Results Spiral CT (HRCTespecially) could find many signs of pulmonary tuberculosis, such as centrilobular distribution nodules, tree-in-bud, cavitations,tuberculous pneumonia, miliary nodules, branchogenic dissemination, endobranchial tuberculosis, lymph node enlargement and calcification. The accuracy of spiral CT in the diagnosis of pulmonary tuberculosis was 96.6%, The accuracy of spiral CT with 3Dreconstruction in the diagnosis of pulmonary tuberculosis was 99.31%.Conclusion Pulmonary tuberculosis can be diagnosed accurately by spiral CT with all kinds of 3D reconstruction.
ABSTRACT
Objective To evaluate spiral CT scanning and CT virtual endoscopy(CTVE) in the clinical diagnosis of gastric carcinoma.Methods Spiral CT scan was performed in 28 patients with pathologically-proved gastric cancer . The CT scan parameters were : collimating width 5 mm , Pitch 1 . The volumetric data were acquired using a spiral CT scanner and transferred to computer workstation . CTVE was performed by navigator smooth function . The results were compared with the findings of fiberoptic endoscopy and/or surgery .Results Spiral CT scan could demonstrate the location ,size,extension of lesions and the relation with organs around .In 28 patients,CT findings included omentum involvement(n=7),pancreatic ivolvement (n=4),hepatic involvement (n=3),lymph node metastasis(n=3). CTVE could clearly demonstrate the three-dimensional image of normal wall stomach and the lesions , size and extension of lesions . The appearances of the inner lesions and normal wall of stomach on CTVE were similar to those on fiberoptic endoscopy and/or surgery . The accuracy in detecting lesion by CTVE was 92.8% in 28 patients . Conclusion CTVE combination with spiral CT scan is of great value in clinical diagnosis of gastric carcinoma .
