"Don't give nitrates to right-sided 🫀myocardial infarctions" This is a myth that continues to get taught due to the theory that right-sided MIs are sensitive to preload, which nitrates reduce. A recent systematic review (n=1113) failed to substantiate this purported risk. #emergency #emergencymedicine #foam #foamed #foamcc #army #armymedicine #armyemdoc #meded #icu #criticalcare #meded #science #research #data #medx #medtwitter

PLAX- PARASTERNAL long axis. One of my favs . . . Here’s a great animation of the anatomy we can assess in the parasternal long axis view (PLAX). This is one of my favorite views (because it’s pretty easy to get) and can help you assess multiple structures in a pinch. . . To obtain this view put your probe on the 3rd-4th rib space with the probe marker facing the right shoulder. From there you can make a quick adjustment (turning the probe marker to the left shoulder) to get the parasternal short axis view (PSAX). Both of these views are great for assessment of wall thickness, the mitral valve, as well as for effusions (among many other things). . . . Even though I’m an interventional cardiologist echo remains one of my most favorite things about cardiology. It’s amazing to me that I can get all of these images myself with a probe and my phone. I encourage all cardiology fellows out there to embrace echo because once you start enjoying it many parts of cardiology become easy! . . . What’s your favorite echo view? . .

How the 🆅🅴🅽🆃🆁🅸🅲🅻🅴 contracts.. . . . 💗Another great thing I picked up from Cardiothoracic surgery was understanding how the ventricles contract. The ventricle Is such a complex structure that we are learning more and more about. One thing that has helped us understand this complex structure is strain imaging and 3D echocardiography. We have learned that the ventricle contracts in 4 ways: contraction (radial) motion but it also has a twisting (torsional and circumferential) and shortening (longitudinal) motion. . . . 👐🏽The surgeon I always work with often described the hearts motion as “wringing of a towel.” This can be seen in the video above. The understanding of the multiple different motions of the heart has allowed us to better understand intrinsic myocardial disease and pick up disease earlier in its process allowing us to add disease modifying agents to slow and sometimes reverse the negative remodeling of the heart. . . . 💓So next time you think of your heart pumping don’t think of it in one motion (squeeze) but rather a Towel being wrung of water. The heart is such an amazing organ and we are just now really beginning to understand it’s truly complex physiology! . . . Have a great day! . . . . #Medicalschool #medschool #cardiologia #doctors #cardiotwitter #meded #EKG #Medstudent #cardiology #internalmedicine #patient #hospital #radiology #physiology #paschool #foamed #echo #physicalexam #anatomy #scrubs #surgery #pastudent #nursingstudent #nursing #PA #DO #Echocardiogram #MD #USMLE

PHOTON COUNTING CT AND A NEW CONCEPT OF NORMAL CORONARY ARTERIES For more than 2 decades we have been performing Cardiac CT with constant improvements in all parameters (spatial, temporal and contrast resolution). The improvements were progressive in certain fields and steep in other (e.g.: the introduction of Dual Source CT that completely changed the range of temporal resolution achievable basically overnight and still is the most important source of flexibility in Cardiac CT scanning after almost 20 years). Spatial resolution instead was improved in a slow and progressive way until the test EID CT generations that achieved a spatial resolution of 250 microns. This allowed us to assess a coronary artery tree and define it as normal when no apprentice changes were visibile up to that value. But we know that the normal thickness of coronary artery walls is quite below that threshold. It is more in the range of 80-200 microns. Therefore, the very early changes in coronary artery wall thickness could not be picked up by EID CT technology. With the introduction of PCCT we can constantly achieve 100 microns spatial resolution which means that we work extol in range in which coronary artery disease starts. It also means that we don't see any thickening of the the coronary artery walls we have a much higher specificity and reliability. This concept is a transformative one because it allows us to shift earlier and earlier the beginning of atherosclerosis in our patients and think even more precisely in terms of cardiovascular prevention and monitoring. Movie: example of normal coronary artery tree with PCCT. A new era is coming into practice and it is the age of Photon Counting CT which pushes this boundaries further away. PCCT is a NEW Imaging Modality. PCCT is changing the game, the field, the language, the priorities and in the end it will change the entire infrastructure of diagnostic medicine. PS: note that PCCT images have to be reduced in resolution when uploaded in social media. #CardiacImaging #MedicalInnovation #StentAssessment #Radiology #PCCT #photoncounting #QuantumHD #CT #computedtomography #yesCCT #coronaryarterydisease #ischemia #naeotomalpha #Peak #Pro #Prime #speed #cardiac #highresolution #siemenshealthinners #CardiacCT #PhotonCountingCT #MedicalImaging #HeartHealth #CardiovascularInnovation #Radiology #AIInMedicine

If you are interested in ego-centric data capture, no need to get a headset or smart glasses. Get a $10 head strap mount and put one of these cameras on it. You get RGB, stereo, depth, 3D point clouds, and camera trajectory. Visualization powered by Rerun. Pretty cool!

Here is a 3D visualization of the coming solar storm using model parameters from NASA's run, NOAA's run (shown below), and the coronagraph views from STEREO-A/COR2 and SOHO/LASCO. The storm is expected to hit Earth early December 9. The 3D visualization clearly shows the low inclination orientation of the solar slinky core inside the larger storm envelope. Of course, the earlier eruption that erupted to the northeast, might deflect this structure a little bit, but likely that will only make the structure move more towards the ecliptic plane, which will give us a larger chance of crossing through the solar slinky core. One nice thing about low inclination flux rope cores is that they almost ALWAYS have southward field in them at some point. So this is good news for aurora photographers-- as long as this solar storm stays true to its launch trajectory and inclination, we could see some organized southward pointed magnetic field. Considering this solar storm is fast-- that usually indicates the storm will not deviate much from its original launch trajectory! Here is the link to a static frame of the 3D frame visualization so you can fly around it yourself:

🔬 Why Perfect Visualization of Stents and Calcified Plaques Requires the Highest Spatial, Temporal and Contrast Resolution: The Case for Ultra-High-Resolution with Photon Counting CT Image: a close look at a RCA stent with very mild intimal hyperplasia. Seeing is everything in coronary imaging. Yet when it comes to stents and heavily calcified plaques, even the best conventional CT systems hit their physical limits — blooming, partial volume effects, and metal artifacts blur what truly matters. That’s where Ultra-High-Resolution Photon Counting CT (PCCT) changes the game. 🧠 Why it matters: Conventional CT often overestimates stenosis in calcified vessels and hides in-stent lumen due to blooming and noise. This leads to diagnostic uncertainty, unnecessary invasive testing, and poor evaluation of stent patency or neo-atherosclerosis. ⚡ What PCCT adds: Ultra-high spatial resolution (0.1 mm voxels) sharply delineates stent struts, plaque borders, and residual lumen. True spectral resolution minimizes blooming and metal artifacts, enhancing visualization even in highly calcified segments. Improved contrast-to-noise enables clear lumen assessment at lower doses. Quantitative, energy-resolved data provide material differentiation between calcium, metal, and contrast — something previously unthinkable in CT. In short, accurate visualization of stents and calcified plaques demands Photon Counting CT — not just for sharper images, but for better diagnostic confidence and patient management. The era of artifact-free coronary imaging has begun — and it’s photon-counting powered. ⚡❤️ #PCCT #CardiacImaging #CoronaryCT #StentImaging #CalciumScore #PhotonCountingCT #PrecisionImaging #CardiovascularImaging #RadiologyInnovation #yesCCT
