In a study of 8,357 patients, an automated machine learning model that integrated clinical and PET MPI data discriminated risk more accurately than logistic regression or a deep neural network. @fares_alahdab @mumedicine @drAhmedIA @YaleMed @almallahmo @MethodistHosp @DeBakeyCVedu Read now👉bit.ly/4rTyJiC

In a study of 498 patients from the 18F-flurpiridaz phase III clinical trial, incorporating deep learning calcium scoring enhanced diagnostic accuracy. @aakash_shanbhag @robertjhmiller @piotr_jslomka @smidtheart. Editorial by @attilafehermd @yalecardiology Read now👉bit.ly/4kS2K0w

#JACCIMG asks: In patients without sarcoidosis with prior normal #whyCMR, what non-specific FDG PET/CT #cvPET patterns are commonly present? jacc.org/doi/10.1016/j.… #cvImaging @True_EP @RonBlankstein @sanjaydivakaran

In older adults (>70 yrs old), exercise-stress MPI using CZT cameras shows reduced diagnostic accuracy for CAD due to lower exercise capacity. Vasodilator-stress MPI maintains better performance. Ischemic burden (SDS) remains a strong predictor of future cardiac events. Read now👉bit.ly/4aMYhsk @RiccardoLiga7 @alessia_gimelli @AoupPisana

Elevated microvascular resistance may be responsible for the pathophysiology of reverse redistribution in perfusion SPECT imaging. Read now 👉 bit.ly/4rOpUY1

Dynamic CZT-#SPECT enables quantification of myocardial blood flow—a cost-effective, widely available alternative to PET. It enhances CAD diagnosis, detects balanced ischemia & microvascular dysfunction, & refines risk stratification. #cvnuc Read now👉bit.ly/3ZmyTn1

Challenges to multimodality imaging training include prolonged length of training, onerous board certification process, and lack of effective collaboration between radiology and cardiology. Tackling these challenges will allow us to recruit the next generation of cardiovascular imagers. Read now👉bit.ly/49ZTu6M

Morning teaching session with the best of the best, doesn’t get better than this! 🌟🙌

95% of Medicare pts live < 16 miles from an echo, but CMR, CT & PET access much more limited. While distance = less CV Imaging in rural areas, those closest to imaging in urban areas had lowest receipt, suggesting distance is insufficient for access. bit.ly/48sAhbH

Our study highlights how cac 0 can identify a large number of low risk patients among those with mildly abnormal stress perfusion who may not need rest imaging

@AmitRPatelMD Thanks @AmitRPatelMD. Underscores the importance of 1. identifying perfusion defects and FDG-avid extracardiac disease, 2. incorporating beta hydroxybutyrate testing, and 3. a multimodality approach with CMR.

Patterns of Nonspecific Myocardial FDG Uptake in Patients Without Sarcoidosis With Normal CMR — Beware, not all FDG uptake on CardiacPET is cardiac sarcoidosis. jacc.org/doi/10.1016/j.…

📢 ATTENTION 🇺🇸Cardiac Imagers->Help us 🙏 understand the contemporary practice of Cardiac Imaging! Complete&Repost➡️Short ACC Imaging Council Survey forms.gle/MuWnGbqNbMbcPG… TOTALLY ANONYMOUS @danilorenzatti @RonBlankstein @ChrisKramerMD #ACCimaging @MyASNC @Heart_SCCT @SCMRorg

*ACC Imaging Council Survey: Define what the job market looks like* - forms.gle/MuWnGbqNbMbcPG… Hi everyone, if you have just a few minutes today, the ACC Imaging Council would love if it you could fill out the following brief survey. We are aiming to gather *anonymized* data on how advanced cardiac imagers jobs are: 1. Structured (# clinic days, # imaging days, call etc.) 2. Valued (MGMA, Doximity, MedAxiom data does not stratify by advanced imaging vs general rads/cards) We hope to share the results with everyone in the community to help you understand your local and national market and empower you to better advocate for yourself in any new or retention contracts to come. The amount of value this survey will add will completely depend on participation, so please share widely with your colleagues and friends in advanced cardiac imaging! I would appreciate a RETWEET Best, Your friends on the ACC Imaging Council #ACCImaging @ACCinTouch @RonBlankstein @WilliamZoghbi @mdicarli docs.google.com/forms/d/e/1FAI… #ACCImaging pic for the attention @mmamas1973 @DrMarthaGulati @iamritu @onco_cardiology @OKhaliqueMD @rooshaparikh @Doc_Tiger

Does correcting MFR for rate-pressure product improve risk prediction? In a study of 4464 patients referred for stress PET MPI, uncorrected MFR < 2 was associated with a higher CV risk, even when corrected MFR was >=2. @almallahmo @MethodistHosp.

Important work from @sanjaydivakaran and the team. #EPeeps

If you are considering inflammatory cardiomyopathy like sarcoidosis and order a PET/CT, you are on to something. Maybe not always cardiac sarcoidosis, but something. Keep looking. @utedrow @RonBlankstein
