Evaluation of a Deep Learning Denoising Algorithm for Dose Reduction in Whole-Body Photon-Counting CT Imaging: A Cadaveric Study.

Acad Radiol

January 2025

Department of Radiology, University Hospital Tuebingen, Hoppe-Seyler-Str. 3, 72076 Tuebingen, Germany (R.D., J.M.B., B.S., J.M., S.G., P.K., S.W., J.H., K.N., S.A., A.B.).

Rationale And Objectives: Photon Counting CT (PCCT) offers advanced imaging capabilities with potential for substantial radiation dose reduction; however, achieving this without compromising image quality remains a challenge due to increased noise at lower doses. This study aims to evaluate the effectiveness of a deep learning (DL)-based denoising algorithm in maintaining diagnostic image quality in whole-body PCCT imaging at reduced radiation levels, using real intraindividual cadaveric scans.

Materials And Methods: Twenty-four cadaveric human bodies underwent whole-body CT scans on a PCCT scanner (NAEOTOM Alpha, Siemens Healthineers) at four different dose levels (100%, 50%, 25%, and 10% mAs).

Background: Surgical treatment of therapy-resistant radiculopathy associated with lumbar herniated discs in patients with extreme obesity is a challenge for neurosurgeons. In addition to technical problems in surgery due to the abundant subcutaneous adipose tissue and perioperative risks, there are significant anesthetic risks when anesthesia is performed with a patient in the prone position. A surgical procedure should preferably be minimally traumatic and quick with minimal risks of complications.

Background: Since patients with congenital heart defects (CHD) frequently require life-long medical care and repeat invasive treatment, radiation exposure during interventional procedures is a relevant issue concerning potential radiation related risks. Therefore, an analysis on radiation data from the German Registry for Cardiac Operations and Interventions in patients with CHD was performed.

Methods: From January 2012 until December 2020 a total of 28,374 cardiac catheter interventions were recorded.

A 65-year-old woman with a history of ductal mammary carcinoma and recent autonomic dysfunction underwent a Rb-82 chloride (RbCl) cardiac PET/CT scan that showed no ischemia or scarring, but significantly reduced myocardial flow reserve (MFR) (global: 1.5) and a CAC-Score of 0. The patient's chemotherapy history (paclitaxel, carboplatin, epirubicin, pembrolizumab 2 years before) with elevated Troponin T and NT-pro-BNP levels at that time, and now reduced MFR with 0 CAC suggests cancer-therapy-related cardiotoxicity.

Health care systems are confronted with an increasing burden of (multi-)morbidity and a shortfall of healthcare providers. Coordination and continuity of care in chronic and multi-morbid patient is especially important. As qualitative patient experience data within care processes is scarce, we aim to increase the understanding of chronically ill patient's perspectives by assessing patient experiences in different health systems while treated in primary care.

Article Synopsis
  • Variance in optical mesoscopic probes limits applications, especially as smaller probes show greater relative variance.
  • Specific viral protein cages, like the murine polyoma virus, can assemble efficiently and accurately, minimizing statistical fluctuations due to quality control.
  • An approach leveraging this assembly results in multichromophore particles that produce brighter, more consistent fluorescence than existing fluorescent nanosphere probes, validated by mass spectrometry and fluorescence microscopy.

Background: Up to now, the optimal duration of immune checkpoint inhibitors (ICI) has not been evaluated in prospective studies. However, current clinical practice requires decisions to be made regarding the duration of ICI in complete responders.

Material And Methods: A survey was sent to 80 DeCOG skin cancer centers to assess how decisions are made on treatment duration of ICI in melanoma after having reached complete response, and staging intervals after ICI discontinuation.

Department of Internal Medicine II, Hematology, Oncology, Clinical Immunology and Rheumatology, University Hospital Tübingen, Tübingen, Germany.

Introduction: Multiple myeloma (MM) is an uncontrolled plasma cell proliferation in the bone marrow, leading to immune dysregulation with impaired humoral immune responses. Conversely, cellular-based responses play a vital role in MM patients. However, the extent and duration of cellular-induced protection remain unclear to date.

Clinical characteristics of dengue virus infections in Karachi from 2019 to 2023: a cross-sectional study.

Sci Rep

December 2024

National Institute of Virology, Dr. Panjwani Center for Molecular Medicine and Drug Research, International Center for Chemical and Biological Sciences, University of Karachi, Karachi, 75270, Pakistan.

Dengue fever is a vector-borne, acute, febrile, and self-limiting systemic viral infection that affects tropical and subtropical regions, including Pakistan. Karachi has a significant burden of Aedes aegypti and Aedes albopictus due to suitable breeding sites, weather, and rapid and unplanned urbanization of squatter areas. The country has limited surveillance studies on circulating serotypes of the dengue virus and the patient's clinical features evolving over temporal changes.

: Current guidelines recommend Cisplatin/Gemcitabine/Durvalumab as first-line treatment for inoperable or recurrent cholangiocarcinoma (CCA). Molecular tumor boards (MTB) have the expertise to support organ-specific tumor boards with evidence-based treatment recommendations for subsequent lines of treatment, based on genomic tumor data and scientific evidence. This study evaluates the adoption of an MTB at a comprehensive cancer center in Germany and whether actionable genetic alterations are associated with specific imaging phenotypes.

Adequate post-ischemic reperfusion of the mouse brain requires endothelial NFAT5.

Acta Neuropathol Commun

December 2024

Institute of Physiology and Pathophysiology, Department of Cardiovascular Physiology, Heidelberg University, Heidelberg, Germany.

Severity and outcome of strokes following cerebral hypoperfusion are significantly influenced by stress responses of the blood vessels. In this context, brain endothelial cells (BEC) regulate inflammation, angiogenesis and the vascular resistance to rapidly restore perfusion. Despite the relevance of these responses for infarct volume and tissue recovery, their transcriptional control in BEC is not well characterized.

Institute of Pathology and Neuropathology, Eberhard Karls University of Tuebingen and Comprehensive Cancer Center, University Hospital Tuebingen, Liebermeisterstr. 8, 72076, Tuebingen, Germany.

Only 10% of new lymphoma diagnoses in the USA occur in children < 15 years. Although the same diagnostic criteria apply to both adult and pediatric lymphomas, there are important differences in some lymphoma subtypes. These differences are recognized by the World Health Organization (WHO) with the recent 2022 classification of pediatric tumors including pediatric hematopoietic tumors.

Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare but serious prothrombotic adverse event following vaccination with adenovector-based COVID-19 vaccines. Laboratory findings indicate that anti-platelet factor 4 (PF4) immunoglobulin G antibodies are the causing factor for the onset of thromboembolic events in VITT. However, molecular mechanisms of cellular interactions, signaling pathways and involvement of different cell types in VITT antibody-mediated thrombosis are not fully understood.

  • The study aimed to evaluate how a personalized integrative medicine (IM) intervention affects healthcare providers (HCPs) with war-related emotional/spiritual and physical concerns.
  • HCPs from five hospital departments in northern Israel received IM treatments, with improvements measured using a specific questionnaire before and after the intervention, and post-treatment narratives were analyzed for emotional/spiritual keywords.
  • Results showed that HCPs who expressed emotional/spiritual keywords experienced significantly greater improvements in their quality of life concerns compared to those who did not, highlighting the need for further research on integrating IM with mental health support during crises.
