What a wonderful time presenting at #ACC25. -No difference in outcomes btw Stress Only Spect Imaging V Stress/Rest Imaging if first scan is normal. Thankful to my mentor Mouaz Al-Mallah, M.D MSc for the constant support and guidance, and my team alwan maria Ahmad El Yaman Ahmed Sayed

How have HCM mortality rates changed before and after COVID ❓ 1⃣ Prior to COVID, mortality rates declined by ~ half📉 2⃣ After COVID, mortality rates increased by ~30%, partially undoing some of the prior reductions in HCM mortality.📈 Open access📜: ahajournals.org/doi/full/10.11…

For ASNC Society PET Workshop: James Chase & Mouaz Al-Mallah (Mouaz Al-Mallah, M.D MSc) compared Rb-82 & Flurpiridaz for myocardial perfusion. Flurpiridaz shines with ~94% extraction fraction & better image resolution, promising enhanced cardiac PET imaging. #CvNuc #ThinkPET #Flurpiridaz

💡Flurpiridaz PET From ASNC Society PET Workshop: Start the scanner before injecting the 2nd dose to capture residual activity. ✅Enables residual subtraction → accurate MBF Left: No subtraction = overestimated MBF Right: With subtraction = true MBF Mouaz Al-Mallah, M.D MSc Edward Miller, MD PhD

#EHJCVI 🧱 What’s the interplay between CAC, MFR and cardiovascular events? CAC density is inversely associated with outcomes, while CAC volume is positively associated 📈 Were these significant after adjusting for MFR and other factors? Read more 👉 doi.org/10.1093/ehjci/…

🔥New data: In 2022, only 14.2% of cardiac imagers were women—up from 10.5% in 2013. 📉 Representation remains low in: •PET: 10.5% •SPECT: 12.6% •Interventional echo: 6.5% 🧠 More women are entering imaging—but gender gaps persist, especially in multimodality & leadership

ICYMI: Cardiac PET & PET/CT have earned 🆕 indications in recently published guidelines from the ACC/AHA, European Society of Cardiology, & the The ISHLT. To help you translate these recommendations into practice, Journal of Nuclear Cardiology published a State-of-the-Art Review article documenting where PET is now
