Does gamma-glutamyltransferase correlate with liver tumor burden in neuroendocrine tumors?

Purpose: In patients with neuroendocrine tumors (NETs) and liver metastases, increased gamma-glutamyltransferase (GGT) is commonly assumed as an indicator for progressive disease. To date, however, empirical data are lacking. This study aimed to investigate associations between GGT and liver tumor burden.

Diagnostic Imaging of Patellofemoral Instability.

Background:  Throughout the literature, patellofemoral instability (PI) is defined as an increased risk of re-/luxation of the patella within the patellofemoral joint (PFJ). In most patients it is caused by traumatic patella luxation or the existence of a range of predisposing anatomic risk factors leading to an unphysiological movement sequence within the PFJ also known as patellofemoral maltracking. In order to provide an individualized therapy approach, clinical and radiological evaluation of those risk factors of variable magnitude becomes essential.

Magnetic resonance imaging of midtarsal sprain: Prevalence and impact on the time of return to play in professional soccer players.

Background: Ankle sprain is a common injury in professional soccer, but to date midtarsal sprain has not been investigated in this context. The purpose of this study was to determine the prevalence of midtarsal sprain by MRI and to assess its impact on the time of return to play in professional soccer players.

Methods: We included 52 professional soccer players who underwent 59 MRI examinations after acute ankle trauma between January 2012 and September 2019.

Dual-Energy Computed Tomography for Fat Quantification in the Liver and Bone Marrow: A Literature Review.

Background:  With dual-energy computed tomography (DECT) it is possible to quantify certain elements and tissues by their specific attenuation, which is dependent on the X-ray spectrum. This systematic review provides an overview of the suitability of DECT for fat quantification in clinical diagnostics compared to established methods, such as histology, magnetic resonance imaging (MRI) and single-energy computed tomography (SECT).

Method:  Following a systematic literature search, studies which validated DECT fat quantification by other modalities were included.

[Diagnostic imaging and classification of proximal femoral and tibia fractures in adults].

Background: A confident diagnosis and classification of proximal femoral and tibia fractures are crucial to determine further therapeutic procedures.

Materials And Methods: In this article the current standards regarding diagnostic imaging of proximal femoral and tibia fractures are presented and the different classification systems are discussed.

Conclusions: Plain radiography in two planes remains the initial investigation of choice for suspected osseous injury.

Maximum tensile stress and strain of skin of the domestic pig-differences concerning pigs from organic and non-organic farming.

The purpose of this work has been to determine differences in biomechanical properties of porcine skin from organic and non-organic farming as porcine skin is widely used as a model for human skin. A test apparatus was used, using gravity to stretch and finally tear a dumbbell-shaped specimen of prepared abdominal skin with a testing surface area of 25 × 4 mm. A total of 32 specimens were taken from seven individual pigs, three from organic and four from non-organic farming, in different orientations with respect to the Langer's lines.
