ABSTRACT
Objective To evaluate the application of STIC with segmented analytical method in the diagnosis of fetal atrial septal defect. Method Review the 6600 high-risk pregnant women who accepted PHILIPS iE33 Echocardio graphy examination in our hospital , twelve cases by two-dimensional echocardiographicas atrial septal defect then using real-time STIC method to collect data and offline playback compared with sonography after birth. Results Compared with two-dimensional gray-scale ultrasonography , in the diagnosis of fetal atrial septal defect the coincidence rate of STIC with segmented analytical method was 96.5% and 96.7% respectively , no statistically difference between them (P > 0.03). However, the operating time in STIC with segmented analytical method is shorter, and with the statistically significant (P < 0.03). Conclusion Compared with gray-scale ultrasound , STIC technique combined with segmented analytical method can obtain more valuable information and improve the diagnosis coincidence rate , which is a valuable new technology.
ABSTRACT
Objective To evaluate the value of the application of ultrasonic elastography and ultrasound contrast imaging on thyroid microcarcinoma(TMC). Methods The in-patients with thyroid lesions admitted in the Second People's Hospital of Foshan City from January 2013 to April 2014 were enrolled. Two-dimensional ultrasonography was used to screen the 162 solid thyroid nodules with a diameter ≤10 mm;they were examined by ultrasonic elastography and ultrasound contrast imaging respectively,and the result of pathological examination was regarded as the golden standard to compare the sensitivity and specificity between ultrasonic elastography and ultrasound contrast imaging for the diagnosis of TMC. Results The pathological results showed there were benign nodules 118 and malignant nodules 44 in number. The sensitivity,specificity,incidence of accuracy,positive predictive value and negative predictive value of the diagnosis of TMC by ultrasonic elasticity imaging,ultrasound imaging,and elasticity imaging combined with ultrasound imaging were much higher than those by two-dimensional ultrasonography〔sensitivity:88.64%(39/44),90.91%(40/44),95.45%(42/44)vs. 81.82%(36/44);specificity:91.53%(108/118),92.37%(109/118),95.76%(113/118)vs. 85.59%(101/118);accuracy:90.74%(147/162), 91.97%(149/162),93.26%(151/162)vs. 84.56(137/162);positive predictive value:79.59%(39/49),81.63%(40/49),83.67%(41/49)vs. 67.92%(36/53);negative predictive value:95.58%(108/113),96.46%(109/113), 97.35%(110/113)vs. 92.66%(101/109),all P<0.05〕. Conclusion For the diagnosis of TMC,both ultrasonic elastography and ultrasound contrast imaging have rather high value,and when they are combined together to be applied for the diagnosis,the result is the best.
ABSTRACT
In light of the spread and establishment of hospital information systems in the Shanghai area,the paper argues that government departments in charge ought to start in good time research on digitalized hospitals so as to better standardize how hospitals should promote in an active and steady manner a new round of development of hospital information systems.It also gives a detailed account of the content and methods of research on digitalized hospitals as well as development strategies in Shanghai.
