Patient Centered Radiology - An Introduction in Form of a Narrative Review.

Background: Patient centered radiology represents a crucial aspect for modern sustainable radiology. The definition of patient-centered consists of a focus on patients' individual values and wishes with a respectful integration in medical decisions. In this narrative review we try to give a practical introduction into this complex topic with the extension to a person-centered radiology, which additionally encompasses values and wishes of radiological and other medical colleagues.

Structured Reporting of Whole-Body Trauma CT Scans Using Checklists: Diagnostic Accuracy of Reporting Radiologists Depending on Their Level of Experience.

Purpose:  Evaluation of the diagnostic accuracy of a checklist-style structured reporting template in the setting of whole-body multislice computed tomography in major trauma patients depending on the level of experience of the reporting radiologist.

Materials And Methods:  A total of 140 major trauma scans with the same protocol were included in this retrospective study. In a purely trial-intended reading, the trauma scans were analyzed by three radiologists with different levels of experience (resident, radiologist with 3 years of experience after board certification, and radiologist with 7 years of experience after board certification).

Risk to Radiology Staff for Occupational COVID-19 Infection in a High-Risk and a Low-Risk Region in Germany: Lessons from the "First Wave".

Purpose: The recent COVID-19 pandemic has resulted in an increasing overload of the medical system. Healthcare workers (HCW) in radiology departments are exposed to a high infection risk similar to HCWs in the ICU or dedicated COVID wards. The goal of our paper is to evaluate the prevalence of IgG antibody against SARS-CoV-2 among radiology HCWs in two different hospitals and regions in Germany with a low and high COVID-19 prevalence and to compare it to the prevalence in other clinical personnel.

Clinical Value of CT for Differentiation between Ascites and Hemorrhage: An Experimental In-Vitro Study.

Background: Abdominal trauma, leading to intra-abdominal bleeding, is a life-threatening condition that might need emergency surgical intervention. Sonography and Computed Tomography (CT) are most commonly used to detect free intra-abdominal fluid. This study investigates the accuracy of CT to distinguish between ascites and intra-abdominal hemorrhage.

Dynamic contrast-enhanced computed tomography for the diagnosis of solitary pulmonary nodules: a systematic review and meta-analysis.

Introduction: A systematic review and meta-analysis were performed to determine the diagnostic performance of dynamic contrast-enhanced computed tomography (DCE-CT) for the differentiation between malignant and benign pulmonary nodules.

Methods: Ovid MEDLINE and EMBASE were searched for studies published up to October 2018 on the diagnostic accuracy of DCE-CT for the characterisation of pulmonary nodules. For the index test, studies with a minimum of a pre- and post-contrast computed tomography scan were evaluated.

Fat suppression in magnetic resonance imaging of the head and neck region: is the two-point DIXON technique superior to spectral fat suppression?

Objective: The aim of our study was to systematically compare two-point Dixon fat suppression (FS) and spectral FS techniques in contrast enhanced imaging of the head and neck region.

Methods: Three independent readers analysed coronal T weighted images recorded after contrast medium injection with Dixon and spectral FS techniques with regard to FS homogeneity, motion artefacts, lesion contrast, image sharpness and overall image quality.

Results: 85 patients were prospectively enrolled in the study.

Incidence of traumatic carotid and vertebral artery dissections: results of cervical vessel computed tomography angiogram as a mandatory scan component in severely injured patients.

Purpose: The aim of this study was to evaluate the true incidence of cervical artery dissections (CeADs) in trauma patients with an Injury Severity Score (ISS) of ≥16, since head-and-neck computed tomography angiogram (CTA) is not a compulsory component of whole-body trauma computed tomography (CT) protocols.

Patients And Methods: A total of 230 consecutive trauma patients with an ISS of ≥16 admitted to our Level I trauma center during a 24-month period were prospectively included. Standardized whole-body CT in a 256-detector row scanner included a head-and-neck CTA.

Clinical Value of Contrast Enema Prior to Ileostomy Closure.

 To determine the value of routine contrast enema of loop ileostomy before elective ileostomy closure regarding the influence on the clinical decision-making.  Retrospective analysis of contrast enemas at a tertiary care center between 2005 und 2011. Patients were divided into two groups: Group I with ileostomy reversal, group II without ileostomy closure.

Vascular geometry as a risk factor for non-penetrating traumatic injuries of the aortic arch.

Purpose: To assess biomechanical factors in aortic arch geometry contributing to the development of non-penetrating aortic arch injury (NAAI) in multiply injured patients with an Injury Severity Score (ISS) ≥ 16.

Material And Methods: 230 consecutive multiply injured trauma patients with an ISS ≥ 16 admitted to our Level-I trauma center during a consecutive 24-month period were prospectively included of whom 13 presented with NAAI (5.7%).

Non-penetrating traumatic injuries of the aortic arch.

Background In severely injured trauma patients, non-penetrating aortic arch injuries (NAAI) have a remarkable incidence and mortality. Both diagnostics and therapy of NAAI recently underwent significant changes. Purpose To assess mortality, morbidity, and the risk factors associated with NAAI in severely injured patients (Injury Severity Score [ISS] ≥16) under the light of recent technical and procedural advances in trauma care.

Analysis of Radiological Case Presentations and their Impact on Therapy and Treatment Concepts in Internal Medicine.

 Evaluation of clinical impact regarding diagnostic and therapeutic changes influenced by interdisciplinary radiological case presentations.  Prospective evaluation of radiological-gastrointestinal clinical case conferences over a 1-year period at a tertiary care center. We documented the preparation (phase 1) and clinical case conference (phase 2) regarding their impact on the radiology report and further diagnostic work-up and therapy.

Leukocyte-Reduced Platelet-Rich Plasma Treatment of Basal Thumb Arthritis: A Pilot Study.

A positive effect of intra-articular platelet-rich plasma (PRP) injection has been discussed for osteoarthritic joint conditions in the last years. The purpose of this study was to evaluate PRP injection into the trapeziometacarpal (TMC) joint. We report about ten patients with TMC joint osteoarthritis (OA) that were treated with 2 intra-articular PRP injections 4 weeks apart.

Retrograde stapling of a free cervical jejunal interposition graft: a technical innovation and case report.

Background: Free jejunal interposition is a useful technique for reconstruction of the cervical esophagus. However, the distal anastomosis between the graft and the remaining thoracic esophagus or a gastric conduit can be technically challenging when located very low in the thoracic aperture. We here describe a modified technique for retrograde stapling of a jejunal graft to a failed gastric conduit using a circular stapler on a delivery system.

Assessment of disease behavior in patients with Crohn's disease by MR enterography.

Background: Magnetic resonance imaging (MRI) of the bowel is an increasingly used modality to evaluate patients with Crohn's disease. The Montreal classification of the disease behavior is considered as an excellent prognostic and therapeutic parameter for these patients. In our study, we correlated the behavior assessment performed by a radiologist based on MRI with the surgeons' clinical assessment based on the assessment during abdominal surgery.

Diagnostic value of a hand-carried ultrasound device for free intra-abdominal fluid and organ lacerations in major trauma patients.

Background: Technological progress has led to the introduction of hand-carried ultrasound (HCU) imagers in clinical workflow. The aim of this study is to analyse whether examination with a HCU device is a rapid and reliable alternative to contrast-enhanced multidetector CT (MDCT) scans in diagnosis of free intra-abdominal fluid and organ lacerations in major trauma patients.

Methods: 31 major trauma patients with an injury severity score >15 and the necessity of a MDCT scan (standard of reference) were enrolled prospectively to this study, and additionally examined with a HCU, according to 'focused assessment with sonography for trauma' principles for the assessment of organ lacerations and free intra-abdominal fluid.
