Three-dimensional ultrasound experience in obstetrics.

Abstract: Purpose of review Three-dimensional (3D) ultrasound is a natural development of the imaging technology. Fast computers are essential to enable 3D and four-dimensional (4D) ultrasound pictures. A short review of the technical points and clinical aspects is presented. Our purpose is to acquaint the reader with the possibilities of this new technology and to increase awareness of its present clinical usefulness. A short review of technical information is provided. Recent findings The advantages of 3D and 4D ultrasound in certain areas are unequivocal. Its use in the workup of fetal anomalies involving the face, limbs, thorax, spine and the central nervous system are already applied by most centers. Recent findings The use of this technology in applying color Doppler, in guiding needles for different puncture procedures as well in evaluating the fetal heart are under close research scrutiny. The bonding effect between the parents and their future offspring is becoming evident as 3D ultrasound is used. Consulting specialists understand fetal pathology better and can better plan postnatal interventions. 4D or real time 3D ultrasound was developed and is expected to achieve new meaning with the planned introduction of electronic transducer multilinear arrays. Summary 3D ultrasound is an extremely promising imaging tool to image the fetus. In spite of the scant outcome studies the potential of 3D ultrasound is understood by a large number of obstetricians, maternal fetal specialists and imaging specialists.

Multimodality imaging in nanomedicine and nanotheranostics.

Abstract: Accurate diagnosis of tumors needs much detailed information. However, available single imaging modality cannot providecomplete or comprehensive data. Nanomedicine is the application of nanotechnology to medicine, and multimodality imagingbased on nanoparticles has been receiving extensive attention. This new hybrid imaging technology could provide complementaryinformation from different imaging modalities using only a single injection of contrast agent. In this review, we introduce recentdevelopments in multifunctional nanoparticles and their biomedical applications to multimodal imaging and theragnosis asnanomedicine. Most of the reviewed studies are based on the intrinsic properties of nanoparticles and their application in clinicalimaging technology. The imaging techniques include positron emission tomography, single-photon emission computedtomography, computerized tomography, magnetic resonance imaging, optical imaging, and ultrasound imaging.

Study Design for Concurrent Development, Assessment, and Implementation of New Diagnostic Imaging Technology

Abstract: With current constraints on health care resources and emphasis on value for money, new diagnostic imaging technologies must be assessed and their value demonstrated. The state of the art in the field of diagnostic imaging technology assessment advocates a hierarchical step-by-step approach. Although rigorous, such a hierarchical assessment is time-consuming, and, given the current rapid advances in technology, results are often too late to influence management and policy decisions. The purpose of this article is to discuss a study design in which development, assessment, and implementation of new diagnostic imaging technology take place concurrently in one integrated process. An empirically based pragmatic study design is proposed for imaging technology assessment. To minimize bias and enable comparison with current technology, a randomized controlled design is used whenever feasible and ethical. Outcome measures should reflect the clinical decision-making process based on imaging information and acceptan...
