Cardiac Lymph Flow Features and New Opportunities for Their Experimental Visualization.
Dokl Biochem Biophys
January 2025
Laboratory of Microangiopathic Mechanisms of Atherogenesis, St. Petersburg State University, St. Petersburg, Russia.
The aim of this study was to describe the features of myocardial lymph flow using a new combined method of visualization of the lymphatic system. The study was performed on pig hearts harvested from a local slaughterhouse. The original dye, consisting of lipid-soluble chlorophyll and lipiodol, was injected stepwise into the lymphatic vessels.

Objective: The purpose of this study was to explore microvascular function impairment using first-pass cardiovascular magnetic resonance (CMR) in patients with Takotsubo syndrome (TS). Moreover, we explored myocardial microcirculation in patients with TS and related this to demographic data, cardiovascular risk factors, clinical parameters, cardiac biomarkers, and cardiac function.
Methods: This retrospective study performed CMR first-pass perfusion scans in 42 consecutive patients with TS (37 females, 70.
Serial assessment of coronary artery inflammation using cardiac CT in anthracycline chemotherapy for breast cancer.

Department of Diagnostic Radiology, Graduate School of Medical Sciences, Kumamoto University, 1-1-1 Honjo, Chuo-ku, Kumamoto, 860-8556, Japan.
Objectives: There is limited evidence of the pericoronary fat attenuation index (FAI) as an imaging marker to assess cancer therapy-related cardiovascular toxicity. We aimed to measure FAI in four consecutive coronary CT angiography (CTA) scans before and 3, 6, and 12 months after anthracycline treatment in patients with breast cancer to determine trends in dynamic changes in FAI after treatment.
Methods: We performed a post hoc analysis of a prospective study (between August 2019 and July 2020) in which anthracycline-induced myocardial injury was evaluated using cardiac CT.
On the Effect of the Patient Table on Attenuation in Myocardial Perfusion Imaging SPECT.

Institute of Radiology, Nuclear Medicine and Molecular Imaging, Heart and Diabetes Center North Rhine-Westphalia, University Hospital (Ruhr University Bochum), Medical Faculty OWL (Bielefeld University), Bad Oeynhausen, Germany.
Background: The topic of the effect of the patient table on attenuation in myocardial perfusion imaging (MPI) SPECT is gaining new relevance due to deep learning methods. Existing studies on this effect are old, rare and only consider phantom measurements, not patient studies. This study investigates the effect of the patient table on attenuation based on the difference between reconstructions of phantom scans and polar maps of patient studies.

Department of Radiology, Azienda Ospedaliero Universitaria (A.O.U.), di Cagliari - Polo di Monserrato s.s. 554 Monserrato (Cagliari), Monserrato, 09045, Italy.
The purpose of this study was to explore the impact of papillary muscle (PPM) infarction on left atrial and ventricular strain parameters in patients with non-anterior ST-segment elevation myocardial infarction (NA-STEMI) using cardiovascular magnetic resonance (CMR). This retrospective study performed CMR scans on 88 consecutive patients with NA-STEMI (68 males, 65 ± 10.05 years).
