PET/MRI Assessment of Acute Cardiac Inflammation 1 Month After Left-Sided Breast Cancer Radiation Therapy
Conclusion: Myocardial 18F-FDG uptake and functional MRI, including stroke volume and ECVs, were sensitive to changes at 1 mo after breast cancer RT, with findings suggesting an acute cardiac inflammatory response to RT.PMID:37192822 | DOI:10.2967/jnmt.122.264960

The role of intracranial artery calcification (IAC) in stroke subtype and risk of vascular events
CONCLUSION: In these multiethnic populations, IAC is associated with symptomatic and asymptomatic ILAS as well as higher mortality. IAC may be a useful marker of higher mortality, the role of IAC as an imaging marker of risk of stroke is less certain.PMID:37186970 | DOI:10.1016/j.jstrokecerebrovasdis.2023.107185

A systematic review examining the effect of vitamin D supplementation on functional outcomes post-stroke
CONCLUSIONS: The majority of studies showed a statistical improvement in motor function, mobility, and stroke impairment with vitamin D supplementation; however, the evidence did not support an improvement in activities of daily living with treatment. Despite this, there may not be clinical significance. Strong, methodologically sound, randomized controlled trials are required to verify these findings.PMID:37166229 | DOI:10.1177/02692155231174599

Dual-Layer Detector Cone-Beam CT Angiography for Stroke Assessment: First-in-Human Results (the Next Generation X-ray Imaging System Trial) INTERVENTIONAL
CONCLUSIONS:
In a single-center stroke setting, dual-layer detector cone-beam CTA virtual monoenergetic images are noninferior to CTA under certain conditions. Notably, the prototype is hampered by a long scan time and is not capable of contrast media bolus tracking. After excluding examinations with such scan issues, readers considered dual-layer detector cone-beam CTA noninferior to CTA, despite more artifacts.

Systemic arterial calcium burden in patients with chronic limb-threatening ischemia
CONCLUSIONS: In CLTI patients nearly all arterial territories are severely calcified, suggesting that systemic calcification plays an important role in the poor outcome of this disease.PMID:37150661 | DOI:10.1016/j.jcct.2023.03.003

Tumor Genomic Profile Is Associated With Arterial Thromboembolism Risk in Patients With Solid Cancer
CONCLUSIONS: In a large genomic tumor-profiling registry of patients with solid cancers, alterations in KRAS and STK11 were associated with an increased risk for ATE independent of cancer type. Further investigation is needed to elucidate the mechanism by which these mutations contribute to ATE in this high-risk population.PMID:37144118 | PMC:PMC10152200 | DOI:10.1016/j.jaccao.2023.01.009

The prognostic role of right ventricular dysfunction in patients with hypertrophic cardiomyopathy
AbstractHypertrophic cardiomyopathy (HCM) primarily affects the left ventricle (LV) sparing the right ventricle (RV) in vast majority of cases. However, several studies employing CMR have revealed that myocardial hypertrophy may also involve the RV. To assess RV size and function in a large prospectively cohort of HCM patients and to evaluate whether these parameters in association with other MR findings can predict cardiac events. Two participating centers prospectively included patients with known or suspected HCM between 2011 and 2017. CMR studies were performed with three different scanners. Outcome measures were a com...

Scientists use AI to decipher words and sentences from brain scans
A technique based on artificial intelligence (AI) can translate brain scans into words and sentences, a team of computational neuroscientists reports. Although in the early stages and far from perfect, the new technology might eventually help individuals with brain injuries or paralysis regain the ability to communicate, researchers say.
The study “shows that, using the right methods and better models, we can actually decode what the subject is thinking,” says Martin Schrimpf, a computational neuroscientist at the Massachusetts Institute of Technology who was not involved in the work.
Other research teams hav...
