Expert Perspectives: Defining and Managing Progressive Pulmonary Fibrosis in Systemic Sclerosis

Arthritis &Rheumatology, EarlyView.
Systemic sclerosis–associated interstitial lung disease (SSc‐ILD) is one of the leading causes of morbidity and mortality in SSc, affecting up to three‐quarters of patients. The disease course is highly heterogeneous, ranging from indolent, nonprogressive forms to rapidly progressive pulmonary fibrosis (PPF).

Paediatric development of radiopharmaceutical imaging agents and radioligand therapeutics

British Journal of Clinical Pharmacology, EarlyView.
Abstract This review focuses on the development of radiopharmaceutical imaging agents and radioligand therapeutics for paediatric use. Nuclear medicine plays an important role in the diagnosis and treatment of various childhood conditions, including cancers, infections and brain disorders.

Caveolin‐1 enriched apoptotic bodies derived from oral hard palate orchestrate bone remodeling to treat heterotopic ossification

BMEMat, EarlyView.
Downregulated CAV1 in HO is restored via apoptotic bodies from PMSCs, which reprogram bone remodeling by delivering CAV1 to target cells, highlighting the therapeutic role of EV subtypes in heterotopic ossification. Abstract Heterotopic ossification (HO) is a pathological process characterized by ectopic bone formation in non‐osseous tissues, with an ...

Influence of virtual monoenergetic reconstructions on coronary CT angiography-based fractional flow reserve with photon-counting detector CT: intra-individual comparison with energy-integrating detector CT

Insights into Imaging
Objectives This study aimed to assess the impact of the photon-counting detector (PCD)-CT-based virtual monoenergetic image (VMI) reconstruction keV levels on CT-based fractional flow reserve (CT-FFR), compared to the energy-integrating detector (EID)-CT.

Validation of an Automated Artificial Intelligence‐Driven Planner for Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Preprocedural planning with multislice computed tomography (MSCT) is an essential prerequisite for successful transcatheter aortic valve replacement (TAVR). However, preprocedural planning is time‐consuming and may contain clinically meaningful interobserver variability.

Thermally Activated Delayed Fluorescence: An Extended Study of Peripherally Substituted DMAC‐TRZ Analogues

Chemistry – A European Journal, EarlyView.
A comprehensive experimental and theoretical study is presented of a family of TADF dyes. Comparing the behavior of structurally related dyes, we uncover the subtle and somewhat unexpected role of conformational degrees of freedom associated with peripheral groups that affect the delicate interplay of excited states that governs spin–orbit coupling ...

An Image-Based Prior Knowledge-Free Approach for a Multi-Material Decomposition in Photon-Counting Computed Tomography

Diagnostics
Photon-counting CT systems generally allow for acquiring multiple spectral datasets and thus for decomposing CT images into multiple materials. We introduce a prior knowledge-free deterministic material decomposition approach for quantifying three ...

Nonenhanced photon counting CT of the head

, 2023
\(\bf Purpose\) Nonenhanced computed tomography (CT) of the head is among the most commonly performed CT examinations. The spectral information acquired by photon counting CT (PCCT) allows generation of virtual monoenergetic images (VMI). At the same time, image noise can be reduced using quantum iterative reconstruction (QIR). In this study, the image
