Abstract Two-dimensional ultrasound is commonly used in gynecologic patients. It has been shown to be very useful for diagnosing pelvic pathology in both asymptomatic and symptomatic patients. Three-dimensional ultrasound is a new imaging modality, which is being introduced into clinical practice. Although this technique will not probably replace two-dimensional ultrasound, it is being increasingly used. It has been reported that 3DUS is a very high reproducible technique that may have applications in the field of gynecology. These applications include imaging of the uterus, uterine cavity, adnexa and pelvic floor, as well as very interesting applications using three-dimensional power-Doppler ultrasound. The aim of this paper is addressing some technical features of three-dimensional ultrasound and reviewing its current status in clinical practice.

Ovarian Pathology

Abstract Three-dimensional Power Doppler ultrasound is a new imaging modality for assessing tissue vascularization, which is being introduced into clinical practice and it is being increasingly used. In the last years a number of papers assessing the role of this method for assessing adnexal masses vascularization have been published. The aim of this work is to address some technical aspects of 3D US, to review critically its current status in clinical practice and to address future perspectives of its use.

Mitral stenosis is an important cause of heart valve disease globally. Echocardiography is the main imaging modality used to diagnose and assess the severity and hemodynamic consequences of mitral stenosis as well as valve morphology. Transthoracic echocardiography (TTE) is sufficient for the management of most patients. The focus of this review is the role of current two-dimensional (2D) and three-dimensional (3D) echocardiographic imaging for the evaluation of mitral stenosis.

Reliable Methods

Dear Editor, Two-dimensional (2D) echocardiography is a powerful tool for assessment of mitral regurgitation (MR) [1]. However, it bears several major disadvantages. Evidence suggests that measurement of the vena contracta area (VCA) via a three-dimensional (3D) method is significantly more accurate than 2D methods in the quantification of MR since the 2D method is not sufficiently reliable in calculation of VC diameter because of  circular assumption of VC area [2]. VCA direct planimetry (DP) and multiplanar reconstruction (MPR)-derived VCA are direct and reliable methods to quantify MR severity, and their results are comparable with those of 2D integrative method [2, 3]. It is strongly recommended that these methods especially DP can replace 2D methods in the quantification of MR in the clinical practice, as it is more accurate and easy to perform [3].

The Right

Right ventricular (RV) performance is an important predictor of adverse events and mortality in patients with cardiovascular diseases. Echocardiography is the first-choice imaging modality for the assessment of RV systolic function, however conventional two-dimensional echocardiographic parameters have important limitations and under specific conditions poorly correlate with the gold-standard imaging modality, cardiac magnetic resonance. Recent advances in novel echocardiography techniques, including three-dimensional echocardiography and two-dimensional speckle-tracking echocardiography opened new era in RV imaging enabling more accurate and reproducible assessment of RV performance thus providing deeper insight into the pathophysiology of this intriguing cardiac chamber. In this comprehensive review authors summarize the state-of-the-art echocardiographic approach to the assessment of the RV systolic function with specific emphasis on modern techniques, their advantages, limitations and pitfalls in the various clinical settings.

Abstract Although three-dimensional ultrasound (3DUS) has been available for more than 10 years in Indonesia, there was no publishing article from our region which systematically evaluates our experiences in this most recent ultrasound technologies and its application to obstetric. 3DUS is revolving into a technology with various range of applications in numerous fields because it helps overcome some of the key limitations related to two-dimensional imaging. It is through this review that we attempt to develop a continuous line of understanding the current diagnostic benefits of 3D and 4DUS in diagnosis of fetal abnormalities and consider the utility and role of this type of imaging in the routine clinical practice.

Preliminary Research

In biological tissue, there are different kinds of endogenous chromophores. Their absorption spectra in the optical range are sensitive to the physiological change of the animal body. In the near-infrared region (700-1200 nm wavelength), hemoglobin has a characteristic absorption spectrum which is dependent on its redox state. Therefore, the functional information inside the animal body could be obtained noninvasively by measuring the transmitted light. By detecting the change of the absorption characteristics of the animal body, the functional change inside the body can be detected in a two-dimensional transillumination image. In this paper, we propose preliminary research on developing a novel imaging modality of biological body parts. Using the two-dimensional images obtained in many different orientations, three-dimensional physiological function imaging of the biological body by transillumination could be expected. This paper presents a preliminary result in the experiment to show the feasibility of this technique.
