Ziel: Ziel der Studie war, den diagnostischen Stellenwert Kontrastmittelsonografie in Differenzialdiagnose von Leberläsionen im klinischen Alltag einem multizentrischen Ansatz zu evaluieren. Material und Methoden: 1349 Patienten (Männer n = 677, Frauen 672) mit B-Bild Farb-Doppler unklaren Lebertumor wurden Mai 2004 – Dezember 2006 24 Krankenhäusern nach standardisierten Protokoll (Pulsinversionstechnik, mechanischer Index < 0,4) untersucht. Tumortypische Vaskularisationsmuster das...
AIM:To evaluate in a multicenter study whether the sonographic characterization of focal liver lesions can be improved using SonoVue ® -enhancement; and to compare this method with computed tomography (CT) magnetic resonance imaging (MRI).
Ziel: In der prospektiven Studie wurde diagnostische Stellenwert CEUS bei neu festgestellten fokalen Leberläsionen im klinischen Routinebetrieb evaluiert. Ein wichtiger Aspekt ist Vergleich mit Kernspintomografie (MRI). Material und Methoden: 1349 Patienten fundamentalen Ultraschall entdeckten wurden von 05 / 2004 bis 12 2006 prospektiv einer standardisierten untersucht. Ziel war die Bestimmung Tumordignität -entität. 269 nach standardisiert MRI Die definitive Diagnose stützte sich typischem...
Ultrasound contrast agents contain tiny gas-filled microbubbles which on intravenous injection are transported like red blood cells by the bloodstream. They distributed to entire macro- and microvascular system without extravasation (blood-pool tracer). Contrast-specific ultrasound modalities allow selective imaging of these microbubble in real time, with excellent separation from underlying tissue signals. The dynamic wash-in wash-out a bolus allows detection quantitative assessment...
<b>Purpose:</b> The aim of the study was comparison tumor vascularization and contrast enhancement in contrast-enhanced ultrasound (CEUS) for characterization hepatocellular carcinoma (HCC) intrahepatic cholangiocellular (ICC). We present data subpopulations HCC ICC examined DEGUM multicenter trial focal liver lesions clinical practice. <b>Materials Methods:</b> Based on (1349 patients), all patients with histologically proven (n = 278) 42) were analyzed. vascularity pattern during arterial,...
Zusammenfassung Hintergrund: Evaluierung der diagnostischen Treffsicherheit Kontrastmittelsonografie in Differenzialdiagnose kleiner Leberläsionen. Material und Methoden: 1349 Patienten mit im B-Bild Power Doppler unklarem Lebertumor wurden prospektiv mittels KM-Sono multizentrisch standardisiertem Protokoll (mechanischer Index < 0,4, Phase/Puls-Inversion-Technik, Sonovue-Bolus-Injektion) untersucht. Die basierte auf tumortypischen Vaskularisationsmustern arteriellen, portalvenösen Phase...
Ultrasound contrast agents have substantially extended the clinical value of ultrasound, allowing assessment blood flow and distribution in real-time down to microcapillary level. Selective imaging agent signals requires a
Zusammenfassung Ziel: Untersuchung der Häufigkeit von verschiedenen soliden fokalen Leberläsionen (SFLL) in nicht zirrhotischen und Lebern unter besonderer Berücksichtigung Metastasierung Zirrhoselebern.

Objectives As life expectancy rises and the population continues to age, physicians will be faced with an increasing number of elderly patients keratinocyte cancer (KC). This study aims better characterize KC surgery in over 80 years a particular focus on incidence postoperative complications.
Background/Objectives: Pruritus is a prominent symptom of chronic inflammatory skin diseases and significantly affects quality life. Psychological stress can exacerbate pruritus worsen conditions, yet psychological aspects are often insufficiently addressed in clinical routine. While psychodermatological treatments becoming more available German-speaking countries, they mostly confined to specialized clinics, limiting access for many patients. This study aims explore the unmet needs patients...
<sec> <title>BACKGROUND</title> The growing prevalence of allergic diseases, alongside a shortage trained allergists, creates significant challenges in delivering timely care, especially for underserved populations. Telemedicine presents promising solution, offering remote care through digital tools. While telemedicine has been widely adopted other fields, its use allergy remains underexplored. </sec> <title>OBJECTIVE</title> This study aims to assess the potential managing diseases by...
Detection of prostate cancer lesions using transrectal contrast enhanced ultrasound (CEUS) the utilizing quantitative perfusion analysis.20 patients (mean age 63 years, 47-71) with biopsy proven underwent (TRUS) prior to radical prostatectomy by 2 experienced examiners a multifrequency endocavitary probe (5-9 MHZ, LOGIQ E9, GE Healthcare, Chalfont St Giles, UK) detect cancer-suspect lesions. CEUS was performed dynamically up 3 Min after bolus injections 2.4 ml SonoVue® (BRACCO, Italy)....
Impaired gastric emptying is common in critically ill patients. Intestinal dysmotility, a major cause of feed intolerance, may foster infectious complications due to mucosal barrier disruption. However, little known about gut-directed immune activation, intestinal function and its association with impaired patients at ICU admission.We conducted prospective observational study two tertiary care medical ICUs. Fifty consecutive needing invasive mechanical ventilation were recruited within 24 h...
Harmonic imaging increases the signal‐to‐noise ratio in greyscale imaging. With use of ultrasound contrast agents (UCA), brain perfusion seems possible. The authors used an system connection with a 1.8/3.6‐MHz harmonic sector transducer and acoustic densitometry unit for quantification intensity thalamus (THAL), temporoparietal white matter (TPWM), lateral fissure (LF). Ten milliliters BY963, spherosome‐air‐based UCA, was injected intravenously 12 healthy volunteers. Timeintensity curves...
Digital health services are rapidly gaining acceptance in healthcare systems. Dermatology as an image-centric specialty is particularly well suited for telemedical services. However, dermatology patients' demands of electronic remain largely unexplored.This study investigated views primary, secondary, and tertiary referral centers. In August 2017, 841 questionnaires were filled by patients.76.34% expressed interest using digital part medical consultations. 84.41% all patients would complete...
