There is presently a lack of instruments that measure the haptic-perceptive component of body-image distortion – a central criterion for the eating disorders anorexia nervosa and bulimia nervosa. We present a differential analysis for the Test for Body Image Distortion in Children and Adolescents (BID-CA, German: TEK-KJ) using a large child and adolescents sample, including for the first time male participants. We analyze convergent validity with the Contour Drawing Rating Scale (CDRS) as well as differences between children and adolescents from different type of schools and different BMI percentile groups...

Multiple strategies have previously been described for atrial region (i.e. atrial bodies and aortic tract) segmentation. Although these techniques have proven their accuracy, inadequate results in the mid atrial walls are common, restricting their application for specific cardiac interventions. In this work, we introduce a novel competitive strategy to perform atrial region segmentation with correct delineation of the thin mid walls, and integrated it into the B-spline Explicit Active Surfaces framework. A double-stage segmentation process is used, which starts with a fast contour growing followed by a refinement stage with local descriptors...

In addition to cosmetic use, filler materials are frequently employed for reconstruction of contour defects. Scars and tissue defects after accidents, surgery and irradiation are also ideal indications for injectables. The ideal filler should be easy to inject, easy to form, and should remain in the body as long as possible. It should neither be allergenic or carcinogenic nor susceptible to infections or biofilms, but still potentially reversible, temperature-stable, and cheap. There is still no augmentation material that fulfils all of these criteria...

Pierino G Bonanni
PURPOSE: A method for measuring spinal curvature that provides a useful analog to the Cobb angle and is tolerant of degraded image quality is proposed. Conventional methods require a higher standard of discernibility for vertebra features and suffer high variability. METHODS: Assumption is made that the natural representation of the spine for the purpose of scoliosis monitoring is that of a continuous curved contour rather than a series of discrete vertebral bodies with individual orientations...

BACKGROUND: Radiation-related lymphopenia has been associated with poor patient outcome. Our aim was to identify predictors of lymphopenia after palliative radiotherapy, with a focus on dose-volume parameters. PATIENTS AND METHODS: To retrospectively assess patients with various cancers who had undergone palliative radiotherapy, we delineated three organs at risk: the volume enclosed by the body surface contour (body A), the volume left after excluding air, pleural effusion, ascites, bile, urine, and intestinal content (body B), and the volume of the bone marrow (BM)...

INTRODUCTION: The reconstruction of the body shape after post-bariatric surgery or high-grade gynecomastia involves, besides skin tightening, the repositioning of anatomical, apparent landmarks. The surgeon usually defines these during the preoperative planning. In particular, the positions of the nipple-areola complexes (NAC) should contribute to the gender-appropriate appearance. While in the female breast numerous methods have been developed to determine the optimal position of the NACs, there are only a few, metric and often impractical algorithms for positioning the nipples and areoles in the male...

In a previous study, the authors examined the elastic and short-term anelastic springback of Ti6Al4V, CoCrMoC and A316L stainless steel spine rods to observe how the rods mechanically respond in OR contouring. In that study rods were 200 mm long and only the movement at the tip was recorded. The implication of that work was that rods will straighten in-vivo, however, in order for the mechanism of straightening to be determined, the movement of individual bends over time must first be elucidated. Spine rods used were, commercially pure titanium (CP Ti) a primarily α-phase; Ti-6Al-4V; α/β-phase titanium alloy from two different suppliers (denoted by, Ti-6Al-4V (L) and Ti-6Al-4V); β-phase titanium (TNTZ) and CoCrMoC...

BACKGROUND: Massive weight loss (MWL) patients who undergo body contouring plastic surgery (BCPS) display superior long-term weight maintenance. The effect of the number of anatomical areas contoured on weight dynamics is undetermined. OBJECTIVES: To determine whether body mass index (BMI) dynamics following BCPS are associated with the number of anatomical areas operated. METHODS: A retrospective cohort study was conducted. Study groups were defined by the number of anatomical areas operated (1, 2, and 3+)...

PURPOSE: The objective of this study was to introduce and evaluate a method for MR-based attenuation and truncation correction in phantom and patient measurements to improve PET quantification in PET/MR hybrid imaging. METHODS: The fully MR-based method HUGE (B0 Homogenization using gradient enhancement) provides field-of-view extension in MR imaging, which can be used for truncation correction and improved PET quantification in PET/MR hybrid imaging. The HUGE method in this recent implementation is combined with continuously moving table data acquisition to provide a seamless non-truncated whole-body data set of the outer patient contours to complete the established standard MR-based Dixon-VIBE data for attenuation correction...

INTRODUCTION: Body contour surgery (BCS) is a combination of soft tissue resections that have proven to be an effective treatment for the aesthetic and functional problems related to massive weight loss (MWL). There are no studies analyzing the metabolic effect of large volume adipose tissue flap resection in patients with MWL after bariatric surgery. METHODS: This study was a retrospective review of adults who underwent BCS after gastric bypass. Preoperative clinical and laboratory data were compared with 1- and 2-year postoperative follow-up...

PURPOSE: Bolus-tracked multiphasic contrast computed tomography (CT) is often used in diagnostic radiology to enhance the visibility of pancreas tumors, but is uncommon in radiation therapy pancreas CT simulation, and its impact on gross tumor volume (GTV) delineation is unknown. This study evaluates the lesion conspicuity and consistency of pancreas stereotactic body radiation therapy (SBRT) GTVs contoured in the different contrast phases of triphasic CT simulation scans. METHODS AND MATERIALS: Triphasic, bolus-tracked planning CT simulation scans of 10 consecutive pancreas SBRT patients were acquired, yielding images of the pancreas during the late arterial (LA), portal venous (PV), and either the early arterial or delayed phase...

Functional MRI studies in primates have demonstrated cortical regions that are strongly activated by visual images of bodies. The presence of such body patches in macaques allows characterization of the stimulus selectivity of their single neurons. Middle superior temporal sulcus body (MSB) patch neurons showed similar stimulus selectivity for natural, shaded, and textured images compared with their silhouettes, suggesting that shape is an important determinant of MSB responses. Here, we examined and modeled the shape selectivity of single MSB neurons...
