Quantification of the complex breast region can be helpful in breast surgery, which is shaped by subjective influences. However, there is no generally recognized method for breast volume calculation. Three-dimensional (3D) body surface imaging represents a new alternative for breast volume computation. The aim of this work was to compare breast volume(More)
Precise and objective calculation of breast volume is helpful to evaluate the aesthetic result of breast surgery, but traditional methods are unsatisfactory. Three-dimensional (3D) scanning of the body surface allows reproducible and objective assessment of the complex breast region but requires further investigation before clinical application. The main(More)
Differences in breast volume and contour are subjectively estimated by surgeons. 3D surface imaging using 3D scanners provides objective breast volume quantification, but precision and accuracy of the method requires verification. Breast volumes of five test individuals were assessed using a 3D surface scanner. Magnetic resonance imaging (MRI) reference(More)

For the speech ability assessment of glossectomee patients, dynamic MRT was used in order to obtain real time imaging of articulatory movements. At the present state, the method is best suited for continuous consonants, but it can be used for the evaluation of any speech sound. In this study, preand postoperative consonant articulation of eight patients(More)
OBJECTIVES Abdominal aortic aneurysm (AAA) wall is characterized by degradation of extracellular matrix through matrix metalloproteinases (MMPs), chronic inflammatory cell infiltration and extensive neovascularization. So far, MMP expression within AAA wall in association with infiltrates and neovascularization has not yet been studied. METHODS Vessel(More)
Three-dimensional (3-D) recording of the surface of the human body or anatomical areas has gained importance in many medical specialties. Thus, it is important to determine scanner precision and accuracy in defined medical applications and to establish standards for the recording procedure. Here we evaluated the precision and accuracy of 3-D assessment of(More)
Currently, postoperative outcome analysis in breast augmentation is essentially subjective, and objective evaluation of treatment efficacy is lacking. This study evaluates the influence of anatomic and round implant parameters on breast contour changes after subpectoral breast augmentation using three-dimensional (3D) surface imaging. 3D surface breast(More)
BACKGROUND Most atherosclerotic lesions are vascularized, so neovessels may also contribute to plaque progression and vulnerability, but their precise role of neovessels in atherosclerosis is still unknown. The aim of this study was to analyze the possible relationships among neovascularization, relevant angiogenic factors, and plaque vulnerability in(More)
