“…The presentation of volume data instead of slices of data has proved to be clarifying and of additional value, especially in obstetrics. 13 More recently, evidence has become available showing the advantages of 3D sonography in gynecology. In these studies, 3D sonography allowed improved classification of ovarian tumors 14 as well as improved evaluation of the postmenopausal endometrium.…”

Objective. To evaluate the clinical relevance of 3-dimensional saline infusion sonography (3D-SIS) in addition to conventional SIS in women with abnormal uterine bleeding suspected of having intrauterine abnormalities. Methods. All women suspected of having intrauterine abnormalities were eligible. Before 3D-SIS, conventional SIS was performed. The results of these techniques were compared with the "combined method reference standard" (hysteroscopy, endometrial sampling, and clinical followup in cases with normal SIS findings). Diagnostic characteristics (with 95% confidence intervals [CIs]) of 3D-SIS and SIS were calculated as well as their respective accuracy in evaluating the histologic nature, the intrauterine extension, and the location of intrauterine abnormalities. Moreover, the reliability (κ value) and clinical relevance of 3D-SIS were assessed. Results. A total of 49 women were included, and 4 women were excluded. The positive predictive values of 3D-SIS and SIS were, respectively, 1.00 and 0.86 (95% CI, 0.72-0.99; P = .15), and the diagnostic accuracy values were 0.98 (95% CI, 0.94-1.0) and 0.91 (95% CI, 0.83-0.99; P = .08). Saline infusion sonography and 3D-SIS were equally accurate in evaluating the histologic nature, intrauterine extent, and location of intrauterine abnormalities (respective κ values: 0.85 versus 0.93; P = .88; 0.83 versus 0.83; and 0.77 versus 0.80; P = .81). The reliability of 3D-SIS was good: intraobserver and interobserver agreement (κ) were 0.78 and 0.72. Three women (6.7%) had the benefit of additional 3D-SIS: in these women, SIS wrongly led to a diagnosis of intrauterine abnormalities (P = .08). Conclusions. Three-dimensional saline infusion sonography is valid and reliable in women suspected of having intrauterine abnormalities and may indeed have relevant clinical value in addition to conventional SIS.

“…There has been extensive research on the clinical applications of 3DUS, [13][14][15] and recent reports suggest that, when used in conjunction with traditional 2DUS, the enhanced 3DUS images improve several elements of prenatal ultrasonography, including showing fetal defects 13 and allowing a more complete diagnosis. 16 Imaging the fetal face is one of the most widely recognized uses of 3DUS.…”

“…Novel algorithms using the multiplanar display have been proposed for simultaneous display of both outflow tracts 8 , to visualize the aortic and ductal arches 29 and to determine the nature of vascular connections to the fetal heart using the spin technique 30 . The later involves positioning the reference dot in the centre of the structure and "spinning" the volume dataset around the y-axis to determine its spatial relationship with the heart and other vascular structures and to identify its nature.…”

The Role of Spatio-Temporal Imaging Correlation (Stic) in the Prenatal Diagnosis of Congenital Heart Defects

INTRODUCTIONSpatio-temporal image correlation (STIC) is a feature of four-dimensional ultrasonography (4D US) that allows the acquisition of volume datasets akin to blocks of pathological specimens, where all the anatomical information is contained in the block and the information displayed depends on the level at which the block is cut. STIC has the additional advantages that these planes can be assessed in a virtual beating heart, and that rendering techniques can be used to gain additional insight into the structure and function of the fetal heart.With the use of STIC, volume datasets from fetal heart are acquired with a single automated sweep of the transducer, spatial and temporal information are combined to display images that can be extracted from volume datasets. Thus, standard planes for fetal echocardiography, including the four-chamber view, left and right outflow tracts can be obtained from the volume datasets at the time of the sonographic examination or afterwards and novel planes for fetal echocardiography can also be obtained. In addition to this anatomic information, functional information of the fetal heart can be obtained, including the direction of blood flow if the volume dataset was obtained with color Doppler or high definition (HD) power Doppler.Accumulating evidence indicates that 4D US facilitates examination of the fetal heart 1-12 . Thus, 4D fetal echocardiography has the potential to reduce the operator dependency of two-dimensional (2D) US. Prenatal diagnosis of Congenital Heart Diseases (CHDs) is challenging because of the complexity of the fetal heart and the expertise required in performing fetal echocardiography. In addition, fetal and maternal motion, maternal body mass index, gestational age, adequacy of the amniotic fluid volume and fetal position are important factors that can affect image quality. Prenatal diagnosis of CHDs is important because unrecognized CHDs may be associated with worse neonatal outcome. This paper reviews some technical aspects of 4D US, including volume acquisition and rendering, displays modalities in 4D US and summarizes the evidence evaluating the accuracy and reproducibility of 4D US in the prenatal diagnosis of CHDs. ACQUISITION OF VOLUME DATASETS WITH 4D US AND STIC Volume acquisition with mechanical transducersThis is performed with an automated sweep of the transducer, acquiring sequential frames at a rapid rate. Acquisition time ranges from 5 to 15 sec; the longer the acquisition time, the better the spatial resolution. During acquisition, on the basis of changes in the cardiac motion, the STIC algorithm detects the fetal heart rate and synchronizes 2D images. Frames acquired during the same phase in the cardiac cycle are merged into one volume dataset representing approximately 40 volumes. After analysis and rearrangement, the dynamic images are displayed on the screen in three planes that are orthogonal to each other 8 .The image quality contained in an STIC volume dataset can be improved by optimizing the settings before acquisition.
