Abstract

:Simultaneous biplanar radiographic scanning technique (EOS) (EOS Imaging, Paris, France) variability has previously been evaluated for spinal parameters, however limited EOS data exist regarding accuracy of 3-dimensional (3D) rib cage reconstruction. The purpose of this study was to compare the evaluation of ribcage parameter between EOS 3D images and 3D computed tomography (CT) images from adolescent idiopathic scoliosis (AIS) patients, and validate the accuracy of EOS 3D ribcage reconstruction images. In total, 31 AIS patients (27 females, 4 males; mean age 14.4 years) with Lenke types 1 or 2 who underwent corrective surgery were enrolled. EOS 3D images were assessed preoperatively for all patients. Rib cage parameters were measured, including surface spinal penetration index (sSPI), endothoracic hump ratio (EHR), vertebra-sternum angle (VSA), rib-vertebral angle difference (RVAD) at apex and vertebral lateral decentering (VLD). Measurements were subsequently compared with CT images. No significant differences were observed in sSPI or EHR measurements between EOS and CT images. Measured VSA values from EOS and CT were -28.1 degrees and -26.1 degrees, respectively. Measured RVAD values from EOS and CT were 13.0 degrees and 12.0 degrees, respectively. No significant differences were observed for measured VSA or RVAD values between EOS and CT images. Measured VLD values from EOS and CT were 68.5% and 67.5%, respectively, representing similar values. The accuracy of rib cage parameters measured with EOS software is similar to the measurements obtained with CT. The results of this study provide surgeons with important evidence pertaining to this novel imaging technology.

摘要

: 同步双平面射线照相扫描技术 (EOS) (EOS Imaging,Paris,France) 以前已经评估了脊柱参数的变异性,但是关于三维 (3D) 胸腔重建的准确性存在有限的EOS数据。本研究的目的是比较青少年特发性脊柱侧凸 (AIS) 患者EOS 3D图像和3D计算机断层扫描 (CT) 图像之间的肋骨参数评估,并验证EOS 3D肋骨重建图像的准确性。共纳入31例接受矫正手术的Lenke 1型或2型AIS患者 (27例女性,4例男性; 平均年龄14.4岁)。术前评估所有患者的EOS 3D图像。测量胸廓参数,包括表面脊柱穿透指数 (sSPI) 、胸内驼峰比 (EHR) 、椎骨-胸骨角 (VSA) 、脊柱-椎骨角差 (RVAD) 和椎骨侧弯 (VLD)。随后将测量结果与CT图像进行比较。在EOS和CT图像之间的sSPI或EHR测量中没有观察到显著差异。从EOS和CT测得的VSA值分别为-28.1度和-26.1度。从EOS和CT测得的RVAD值分别为13.0度和12.0度。在EOS和CT图像之间未观察到测量的VSA或RVAD值的显著差异。从EOS和CT测得的VLD值分别为68.5% 和67.5%,代表相似的值。用EOS软件测量的肋骨参数的准确性与用CT获得的测量结果相似。这项研究的结果为外科医生提供了关于这种新型成像技术的重要证据。

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.
