🫀 4D Dual-Source Photon-Counting CT in GUCH Patients From Anatomy to True Morpho-Functional Assessment In grown-up congenital heart (GUCH) patients, imaging is rarely simple. Complex anatomy, prior surgeries, devices, and altered hemodynamics require more than static snapshots. Conventional CT gives excellent morphology—but limited function. Other modalities add function—but often at the cost of resolution or accessibility. 4D dual-source Photon-Counting CT (PCCT) brings both together. 🧠 Where conventional imaging struggles - Complex post-surgical anatomy difficult to fully map - Limited temporal resolution for dynamic assessment - Fragmented evaluation across multiple modalities 👉 Result: partial understanding of a complex system ⚡ What 4D dual-source PCCT enables - Ultra-high spatial resolution → precise anatomy, even in complex repairs - High temporal resolution (dual-source) → true cardiac dynamics - 4D datasets → valve motion, ventricular function, flow-related changes - High contrast resolution (with strong iodine signal) → clear chamber and vessel opacification - Spectral capability → added tissue and flow characterization 🎯 The shift From: Static anatomy To: Integrated morph-functional imaging In GUCH patients, understanding structure is not enough. You need to see how it works—beat by beat. That’s where 4D dual-source PCCT redefines cardiac imaging. ⚡🫀 #PhotonCountingCT #PCCT #CardiacCT #GUCH #CongenitalHeartDisease #4DCT #DualSourceCT #CardiacImaging #RadiologyInnovation #yesCCT

DUAL SOURCE PHOTON COUNTING CT AND CARDIAC IMAGING Spatial Temporal Spectral Resolution at their best The temporal resolution of Dual Source scanners is the highest achievable in clinical practice (66ms) and it does not rely on magic tricks and algorithms to show you static Cardiac images. When more than 25 years I started doing Cardiac CT we need very low heart rates (native or induced by negative chronotropic drugs, mostly beta-blockers). Then rotation times of the gantry/detector systems increased and we have better results even at slightly higher heart rates. The real step forward, however, happened when Dual Source CT was introduced drastically cutting in half the time required to acquire one single image (slabs of images). There have been 3 major generations of Dual Source CT and the current benchmark for temporal resolution is 66ms with the 3rd generation of Dual Source CT (FORCE) that is already available since 2014 (!!! 12 years ago). With this technology I personally stopped using IV beta-blockers which was a very common practice for non dual source CT (and still is). I could scan all patients coming in every day regardless the heart rate (high, irregular, and so forth). Arrhythmia is never a contraindication to Cardiac CT in my clinical practice on Dual Source CTs. With Photon Counting that is the starting point. In addition you put on top the outstanding performance of the new detector in terms of noise reduction, spatial resolution, and spectral capabilities; all massively increased. When I say PCCT it's a new imaging modality, I mean it. It generates a new semeiology for Coronary Atherosclerosis and Cardiovascular imaging in general, both because it massively improves the power of your electronic microscope and because it gives you many more imaging tools for tissue imaging making of CT a multiparametric imaging modality. We are entering a phase of great modifications around the Cardiovascular field because of Photon Counting CT. And as it happened with previous leaps all this innovation and improvements will fallout into all the other applications. #PhotonCountingCT #PCCT #DualSourceCT #CoronaryStents #BifurcationImaging #InStentRestenosis #SpectralCT #CoronaryCTA #CardiacImaging #PrecisionCardiology #InnovationInImaging

Photon-Counting CT for Cardiovascular imaging: the new imaging modality 🚀 For years we’ve been pushing energy-integrating detector (EiD) CT to its limits. Even the best-in-class system — the 3rd-generation Dual Source CT (Siemens SOMATOM Force) — has shown how far you can go with high temporal resolution, low kV, Tin filtration, and smart IR/AI recon. It’s an extraordinary scanner. But Photon-Counting CT (PCCT) changes the game because it changes the detector. Here’s why it’s a quantum leap ⬇️ 1. Detector physics, not just better software EiD CT sums all incoming X-ray energy into one signal. PCCT counts and bins individual photons according to their energy. 2. Coronary arteries finally at their native size Coronary imaging is all about small, moving, high-contrast structures. PCCT brings: - ultra-high spatial resolution - minimized blooming - perfect lumen assessment 3. Spectral always-on = better plaque characterization With PCCT you don’t need to choose “dual-energy mode” — it’s intrinsic. 4. Dose–IQ decoupling 5. Beyond what Force can do SOMATOM Force is still the benchmark for EiD CT …but Force still integrates energy. So the message is simple 👇 Force showed us the ceiling of EiD CT. Photon-Counting CT removes that ceiling. 📌 Take-home for coronary imaging Better diagnostic confidence in calcified/stented segments More consistent image quality across patient sizes Native spectral information for smarter, physiology-oriented CT reports A platform ready for AI that works on richer, cleaner data 🚨 If you want to learn, understand, discover the clinical potential of Photon Counting CT register and attend my online course 🚨 17 - 19 Dec 2025 ⏳ Limited spots—secure yours NOW! 🔬 What’s in it for you? ✅ Hands-on training with the latest PCCT tech ✅ CME credits for continued professional growth ✅ Real clinical cases to immediately apply to your practice ✅ Expert-led guidance from industry leaders ✅ Interactive virtual labs to sharpen your skills Why Join Now?

🩻 Dual-Source Photon-Counting CT for In-Stent and Bifurcation Imaging: Bridging the Gap with Intravascular Modalities Assessing coronary stents and adjacent bifurcations has traditionally required invasive intravascular imaging such as IVUS or OCT to overcome the limitations of conventional CT in spatial resolution, blooming, and metal artifact suppression. With dual-source Photon-Counting CT (PCCT), this gap is narrowing rapidly. PCCT enables: 🔬 Ultra-high spatial resolution (voxel 0.1 mm) and minimal blooming artifacts, allowing clear visualization of stent struts, neointimal coverage, and in-stent lumen patency. ⚡ High temporal resolution (~66 ms) with dual-source acquisition, minimizing motion artifacts even in distal or tortuous segments. 🌈 Spectral and quantitative imaging that differentiates iodine from metal, enhancing lumen visualization and supporting iodine-density mapping for neointimal or peristent tissue characterization. 🌿 Accurate assessment of bifurcation anatomy and flow-limiting geometries, including side-branch ostiaemerging from stented segments — a scenario previously accessible only to invasive techniques. By integrating morphological, spectral, and temporal precision, PCCT approaches intravascular-level insight non-invasively, redefining how we evaluate stent integrity, restenosis, and bifurcation hemodynamics.

🔬 Dual-Source Photon-Counting CT for Morphological and Functional Assessment of Myocardial Bridging The evaluation of myocardial bridging (MB) has traditionally relied on morphological imaging, often underestimating its dynamic systolic behavior and potential hemodynamic impact. With the advent of dual-source Photon-Counting CT (PCCT), both morphological and functional characterizationof MB can now be approached within a single non-invasive acquisition. Key enabling features include: ⚙️ Ultra-high spatial resolution (0.1 mm) for accurate delineation of the intramyocardial segment and perivascular tissue interface. ⚡ High temporal resolution (~66 ms) through dual-source acquisition, allowing visualization of systolic compression (“milking”) and diastolic decompression across the cardiac cycle. 🌈 Spectral quantification capabilities, enabling iodine mapping and potentially dynamic perfusion analysis, to correlate luminal narrowing with downstream myocardial enhancement patterns. This integration of temporal, spatial, and spectral information positions PCCT as a unique tool for quantitative, phase-resolved assessment of myocardial bridging — offering insights previously limited to invasive or functional imaging modalities. #PhotonCountingCT #PCCT #DualSourceCT #MyocardialBridging #FunctionalCardiacImaging #SpectralImaging #CardiacCT #PrecisionCardiology #AdvancedImaging

TIME TO MAKE ROOM FOR NEW HIGH PERFORMANCE CT SCANNER IN NAPLES - IRCCS SYNLAB SDN COMPUTED TOMOGRAPHY is the cornerstone of advanced diagnostic imaging. When something gets relevant/serious or complex you usually need a good CT examination. This technology comes from 50 years of development, research and discoveries. In Naples where I've been working for many years now, the work has started. In the picture the glorious Siemens SOMATOM Force (one of the first installed in Italy in early 2017) that I've been using in Naples over the past 8 years to build the Cardiovascular CT program in the city of Naples. We had several thousands of patients undergoing Cardiac and Vascular CT on this scanner every year beside the many thousands of CT in every field of diagnostic imaging on this workhorse. But innovation never stops and we are making room for a newer technology that very soon will push the boundaries of what we can do and offer to our patients further and further.

ECG-Gated Aortic Root & Valve Assessment Type: Prospective ECG-triggered or retrospective ECG-gated Coverage: From tracheal bifurcation to diaphragm (include the entire aortic root and annulus) Phases: Typically 30–75% R-R interval (for dynamic analysis) kVp: 100–120 depending on patient size Slice thickness: 0.5/0.6 mm, overlapping reconstructions Contrast: 60–90 mL at 4 mL/s saline flush Bolus tracking: ROI in ascending aorta, trigger at 120 HU 🔹 B. Non-ECG-Gated Thoracic/Aortoiliofemoral CTA Purpose: Evaluate access route (calcification, tortuosity, vessel diameter) Slice thickness: 1 mm Reconstruction: MPR, MIP, curved MPR for iliofemoral vessels 🧠 Essential Information Extracted ✔️ Annulus diameter, perimeter, area (best measured in systole) ✔️ Sinotubular junction and coronary ostia heights ✔️ Leaflet morphology & calcification burden ✔️ LVOT characteristics ✔️ Aortic angulation ✔️ Access vessel diameters, calcifications, kinks ✔️ Tortuosity score (access route planning) 🚀 Why Dual Source CT Makes a Difference DSCT systems provide critical advantages in pre-TAVI assessment: ✅ High temporal resolution: Up to 66 ms – ideal for imaging aortic root without motion artifacts, even at higher heart rates ✅ Lower contrast dose: Thanks to faster acquisition and dual-energy capability ✅ Robust image quality: Even in arrhythmic or tachycardic patients ✅ Reduced radiation dose: With high-pitch spiral and prospective ECG triggering ✅ Simultaneous evaluation of calcium, lumen, and access with dual-energy imaging ✅ Reliable systolic phase acquisition for annular sizing (typically 30–40% R-R) 📊 Takeaway A well-structured pre-TAVI CT not only reduces procedural risks (e.g. coronary obstruction, annular rupture, vascular complications), but also improves device selection, sizing, and patient outcomes. 💬 Do you routinely use DSCT for TAVI planning? Share your protocol tips or any challenges you’ve encountered below ⬇️ #TAVI #CardiacCT #DualSourceCT #Radiology #StructuralHeart #AorticStenosis #CardiovascularImaging #ImagingProtocols #CTPlanning #StructuralIntervention #HeartTeam📌 CT Protocol for Pre-TAVI Planning using Dual Source CT: A Quick Refresher By Filippo Cademartiri, MD, PhD – Cardiovascular Imaging Transcatheter Aortic Valve Implantation (TAVI) has become a cornerstone treatment for aortic stenosis. DSCT CT imaging plays a crucial role in pre-procedural planning, ensuring optimal outcomes and minimizing complications. 🧭 Pre-TAVI CT Protocol 1. Patient Preparation IV access: 18–20G cannula, preferably antecubital Heart rate control: Not mandatory, but <75 bpm preferred for motion-free aortic root imaging.
