Abstract

OBJECTIVES:This study aims to investigate the usability and reliability of our new axis in a three-dimensional modelling work and demonstrate if it is a reproducible method for anteversion measurement that sufficiently correlates with other computed tomography (CT)-derived gold standards including trans- epicondylar axis (TEA) and posterior condylar axis (PCA). PATIENTS AND METHODS:Three-dimensional solid models were derived from left femoral CT data of 100 participants (50 males, 50 females; mean age 57 years; range, 21 to 86). The newly proposed popliteal surface axis (PSA) was compared with TEA and PCA in terms of anteversion measurement on these solid models. RESULTS:Popliteal surface axis was found as a reproducible reference axis in our study as it could be measured in 99% of our sample. The mean value of PSA based anteversion was (-) 1.8° which was 10.7° and 4.4° for PCA and TEA, respectively. Popliteal surface axis was perfectly correlated with PCA and TEA for anteversion measurements (p<0.001, r=0.92 for both). CONCLUSION:Our findings suggest that the newly defined PSA may be used as an alternative method for determination of anteversion.

摘要

目的: 本研究旨在调查我们的新轴在三维建模工作中的可用性和可靠性,并证明它是否是一种与其他计算机断层扫描 (CT) 衍生的金标准 (包括跨上髁轴 (TEA)) 充分相关的前倾角测量的可重复方法和后髁轴 (PCA)。 患者和方法: 三维实体模型来自100名参与者的左股骨CT数据 (50名男性,50名女性; 平均年龄57岁; 范围,21至86)。在这些实体模型的前倾测量方面,将新提出的popl面轴 (PSA) 与TEA和PCA进行比较。 结果: 在我们的研究中,发现腘面轴是可重复的参考轴,因为它可以在我们的99% 样品中测量。基于PSA的前倾角的平均值为 (-) 1.8 °,PCA和TEA分别为10.7 ° 和4.4 °。对于前倾测量,popl面轴与PCA和TEA完全相关 (p<0.001,两者的r = 0.92)。 结论: 我们的研究结果表明,新定义的PSA可作为测定前倾的替代方法。

METHODS:OBJECTIVES:The aim was to evaluate the image quality and sensitivity to artifacts of compressed sensing (CS) acceleration technique, applied to 3D or breath-hold sequences in different clinical applications from brain to knee. METHODS:CS with an acceleration from 30 to 60% and conventional MRI sequences were performed in 10 different applications in 107 patients, leading to 120 comparisons. Readers were blinded to the technique for quantitative (contrast-to-noise ratio or functional measurements for cardiac cine) and qualitative (image quality, artifacts, diagnostic findings, and preference) image analyses. RESULTS:No statistically significant difference in image quality or artifacts was found for each sequence except for the cardiac cine CS for one of both readers and for the wrist 3D proton density (PD)-weighted CS sequence which showed less motion artifacts due to the reduced acquisition time. The contrast-to-noise ratio was lower for the elbow CS sequence but not statistically different in all other applications. Diagnostic findings were similar between conventional and CS sequence for all the comparisons except for four cases where motion artifacts corrupted either the conventional or the CS sequence. CONCLUSIONS:The evaluated CS sequences are ready to be used in clinical daily practice except for the elbow application which requires a lower acceleration. The CS factor should be tuned for each organ and sequence to obtain good image quality. It leads to 30% to 60% acceleration in the applications evaluated in this study which has a significant impact on clinical workflow. KEY POINTS:• Clinical implementation of compressed sensing (CS) reduced scan times of at least 30% with only minor penalty in image quality and no change in diagnostic findings. • The CS acceleration factor has to be tuned separately for each organ and sequence to guarantee similar image quality than conventional acquisition. • At least 30% and up to 60% acceleration is feasible in specific sequences in clinical routine.

METHODS:BACKGROUND:The main surgical techniques for spontaneous basal ganglia hemorrhage include stereotactic aspiration, endoscopic aspiration, and craniotomy. However, credible evidence is still needed to validate the effect of these techniques. OBJECTIVE:To explore the long-term outcomes of the three surgical techniques in the treatment of spontaneous basal ganglia hemorrhage. METHODS:Five hundred and sixteen patients with spontaneous basal ganglia hemorrhage who received stereotactic aspiration, endoscopic aspiration, or craniotomy were reviewed retrospectively. Six-month mortality and the modified Rankin Scale score were the primary and secondary outcomes, respectively. A multivariate logistic regression model was used to assess the effects of different surgical techniques on patient outcomes. RESULTS:For the entire cohort, the 6-month mortality in the endoscopic aspiration group was significantly lower than that in the stereotactic aspiration group (odds ratio (OR) 4.280, 95% CI 2.186 to 8.380); the 6-month mortality in the endoscopic aspiration group was lower than that in the craniotomy group, but the difference was not significant (OR=1.930, 95% CI 0.835 to 4.465). A further subgroup analysis was stratified by hematoma volume. The mortality in the endoscopic aspiration group was significantly lower than in the stereotactic aspiration group in the medium (≥40-<80 mL) (OR=2.438, 95% CI 1.101 to 5.402) and large hematoma subgroup (≥80 mL) (OR=66.532, 95% CI 6.345 to 697.675). Compared with the endoscopic aspiration group, a trend towards increased mortality was observed in the large hematoma subgroup of the craniotomy group (OR=8.721, 95% CI 0.933 to 81.551). CONCLUSION:Endoscopic aspiration can decrease the 6-month mortality of spontaneous basal ganglia hemorrhage, especially in patients with a hematoma volume ≥40 mL.

METHODS:OBJECTIVE:The primary purpose of this study was to evaluate the effectiveness of a three-dimensional (3D) software tool (smart planes) for displaying fetal brain planes, and the secondary purpose was to evaluate its accuracy in performing automatic measurements. MATERIAL AND METHODS:This prospective study included singleton fetuses with a gestational age (GA) greater than 18 weeks. Transabdominal two-dimensional ultrasound (2DUS) and 3D smart planes images were respectively used to obtain the basic planes of the fetal brain, with five parameters measured. The images, by either two-dimensional (2D) manual or 3D automatic operation, were reviewed by two experienced sonographers. The agreements between two measurements were analyzed. RESULTS:A total of 226 cases were included. The rates of successful detection by automatic display were as high as 80%. There was substantial agreement between the measurements of the biparietal diameter, head circumference and transcerebellar diameter, but poor agreement between the measurements of cisterna magna and lateral ventricle width. CONCLUSIONS:Smart Planes might be valuable for the rapid evaluation of fetal brain, because it simplifies the evaluation process. However, the technology requires improvement. In addition, this technology cannot replace the conventional manual US scans; it can only be used as an additional approach.
