Hyperacute Incidental Late Myocardial Enhancement in Ischemic Stroke Using Chest Spectral CT: Relationship with Etiology
CONCLUSIONS: In this study, hyperacute cardiac imaging of AIS with DESCT identified a high prevalence of incidental cardiac disease predominantly involving LIE of ischemic etiology and mostly not related to the stroke etiology.PMID:35345260 | DOI:10.31083/j.rcm2303093

3D fusion imaging assisted carotid artery stenting is safe and feasible.
CONCLUSIONS: Carotid stenting with 3D fusion in this pilot study was safe and feasible. 3D fusion techniques using either CTA or MRA allowed a significant reduction of contrast volume but did not reduce radiation dose or exposure time. Larger prospective studies of CAS with 3D fusion imaging in patients with renal insufficiency or mild allergy to contrast are warranted. PMID: 31203597 [PubMed - as supplied by publisher]

Experimental cardiac radiation exposure induces ventricular diastolic dysfunction with preserved ejection fraction
Breast cancer radiotherapy increases the risk of heart failure with preserved ejection fraction (HFpEF). Cardiomyocytes are highly radioresistant, but radiation specifically affects coronary microvascular endothelial cells, with subsequent microvascular inflammation and rarefaction. The effects of radiation on left ventricular (LV) diastolic function are poorly characterized. We hypothesized that cardiac radiation exposure may result in diastolic dysfunction without reduced EF. Global cardiac expression of the sodium-iodide symporter (NIS) was induced by cardiotropic gene (adeno-associated virus serotype 9) delivery to 5-w...
