Despite all progress in molecular imaging methods, the actual number of validated new markers is still limited. The breakthrough of individual efforts is often hampered by lack of critical mass of resources. To overcome these shortcomings a "network" of multidisciplinary experts is indispensable. Focusing on cancer therapy, molecular imaging has a high potential impact in (a) early therapy monitoring and (b) prediction of therapeutic response. Novel molecular markers with high diagnostic potential reflecting apoptosis, proliferation and glucose metabolism are currently used in clinical trials for monitoring of tumor response to therapy. A further innovative approach for supporting individualized cancer therapy may be the application of radio-labelled therapeutic drugs at tracer concentrations in order to estimate their individual uptake in the tumor tissue. To meet this challenge, our group initiated a research project focusing on radio-labelling of selected molecules with proven therapeutic potential.

Background: Interstitial lung abnormalities (ILA) are a proposed imaging concept. Fibrous ILA have a higher risk of progression and death. Clinically, computed tomography (CT) examination is a frequently used and convenient method compared with pulmonary function tests.

Cardiomyocytes can be implanted to remuscularize the failing heart. Challenges include sufficient cardiomyocyte retention for a sustainable therapeutic impact without intolerable side effects, such as arrhythmia and tumour growth. We investigated the hypothesis that epicardial engineered heart muscle (EHM) allografts from induced pluripotent stem cell-derived cardiomyocytes and stromal cells structurally and functionally remuscularize the chronically failing heart without limiting side effects in rhesus macaques.

Acoustically probing biological tissues with light or sound, photoacoustic and ultrasound imaging can provide anatomical, functional, and/or molecular information at depths far beyond the optical diffusion limit. However, most photoacoustic and ultrasound imaging systems rely on linear-array transducers with elevational focusing and are limited to two-dimensional imaging with anisotropic resolutions. Here, we present three-dimensional diffractive acoustic tomography (3D-DAT), which uses an off-the-shelf linear-array transducer with single-slit acoustic diffraction.

In recent decades, the diagnosis of thyroid cancer, especially the papillary type, has increased significantly due to the use of imaging techniques such as ultrasound. For this reason, it is essential to rationalize diagnosis and treatment, since the behavior of thyroid cancer varies from slow-progressing tumors to highly aggressive ones. The application of risk assessment systems for ultrasound images and the optimization of cytology incorporating molecular studies allows cases to be stratified in order to select therapy on an individual basis.

Purpose: Posterior fossa ring-enhancing lesions (PFREL) in the adult immunocompetent hosts pose a diagnostic challenge. We aimed to evaluate the spectrum of PFREL etiologies and propose a diagnostic algorithm.
Methods: This study involved a retrospective analysis of PFREL cases from our institution (January 2023 to April 2024) and a systematic literature review conducted using Embase and PubMed databases following the PRISMA 2020 guidelines.
