PHOTON COUNTING CT is NOT a better CT It is a NEW imaging modality Photon Counting CT (PCCT) represents a transformative leap in medical imaging, not only as a molecular imaging modality but also as a technology offering ultra-high resolution and functional imaging capabilities. It is fundamentally more than...

Other than the high resolution and the dose benefits what justifies the very high cost and operational challenges over a spectral CT?

Are all of these non contrast?! And how long does it take to acquire that angiogram and wall motion stuff

It's without and with contrast. The examination is all the same (3-5 min between entering and exiting the scan room).

Absolutely agree with this @FCademartiri . It's like going from black-and-white to colour photography. We started working with him in September at our hospital. Still so much to explore!

Exactly!

Indeed, Photon Counting CT is quite revolutionary. While it introduces new capabilities, particularly in resolution and functional imaging, it also raises interesting questions about its integration into clinical practice. How might this affect diagnostic approaches or patient outcomes compared to traditional CT? For those delving deeper into the biomedical implications of such innovations, is a valuable resource, capable of generating comprehensive biomedical reviews. #Medicine #ImagingInnovation

I don't think so; I have compared the two many times when examining the temporal bone, and there was almost no difference in daily routine 😑

Did you check the quality of the images of the mid and inner ear?

IMO, very useful for heavily calcified coronaries & smaller diameter stents. Makes little difference in the vast majority of CTCAs. Hard to justify the large increase in capital & operating costs. Will be interesting to see how it evolves, particularly functional imaging?

Not really. The point is that it is not a CT. It works as CT with the highest performance, it is an MR in several fields and in the next future it will be a PET as well. This is how you should frame the topic.

🫀 Why Photon-Counting CT Is the New Standard for Non-Invasive Stent Imaging Because “Uninterpretable” Should No Longer Be Acceptable For years, coronary stent evaluation by CTA was often dismissed: “Too much blooming.” “Too much metal artifact.” “Just send the patient to invasive angiography.” That paradigm belongs to the past. Photon-Counting CT (PCCT) is changing non-invasive stent imaging from a limitation into a true diagnostic tool. 🧠 Why conventional CT struggles With standard EID-CT: - Metallic struts create significant blooming - Partial volume effects obscure the intrastent lumen - Small stents become nearly unreadable - Motion artifacts worsen proximal and ostial evaluation The result? 👉 Many stents are labeled “non-diagnostic” 👉 Patients are sent to unnecessary invasive angiography ⚡ Why PCCT changes everything -Ultra-high spatial resolution - Sharper visualization of stent struts - Clear assessment of the true intrastent lumen Reduced blooming artifacts - Metal appears closer to reality - Less artificial lumen narrowing High temporal resolution - Better imaging of proximal, ostial, and fast-moving segments - Reduced motion blur around the stent High iodine concentration contrast (400 mg I/mL) - Strong intraluminal enhancement - Better contrast between lumen and metal - Spectral capability Additional confidence separating iodine signal from stent artifact 🎯 The clinical shift From: “Can we read this stent?” To: “We can characterize it with confidence.” - Restenosis - Stent patency - Aneurysm repair - Complex proximal LAD interventions - Left main and bifurcation stents >>>> all become more reliably assessable. From invasive default to non-invasive confidence and convenience. From metallic blur to diagnostic clarity. That’s why PCCT is becoming the new standard for coronary stent imaging. ⚡🫀 #PhotonCountingCT #PCCT #CoronaryCTA #StentImaging #CardiacCT #CoronaryStent #UltraHighResolution #RadiologyInnovation #yesCCT

🫀 Detecting Diffuse Non-Calcified Coronary Atherosclerosis with Photon Counting CT: Seeing What Conventional CT Often Misses In coronary CTA, the hardest disease to detect is not focal stenosis. It’s diffuse, non-calcified atherosclerosis. No obvious narrowing. No calcium. Just subtle, continuous vessel wall involvement. This is where Photon-Counting CT (PCCT) changes the rules. 🧠 Why it’s difficult Diffuse non-calcified disease presents as: ✔️ Mild, long-segment wall thickening ✔️ Subtle attenuation differences vs lumen ✔️ Positive remodeling without clear stenosis With conventional CT: ✔️ Limited spatial resolution blurs the wall ✔️ Low contrast resolution hides soft plaque ✔️ Motion and noise mask continuity 👉 Result: disease is underestimated or missed ⚡ What PCCT enables ✔️ Ultra-high spatial resolution Clear visualization of the vessel wall along its entire course Detection of subtle, diffuse thickening ✔️ High iodine concentration (400 mg I/mL) Strong intraluminal signal Higher contrast between lumen and vessel wall Diffuse disease becomes visible as a pattern, not noise ✔️ High temporal resolution Reduced motion blur Stable assessment of long coronary segments ✔️ Spectral capability Cleaner iodine–tissue separation Additional confidence in identifying non-calcified plaque 🎯 The shift We move from: Detecting focal stenosis To: Recognizing diffuse atherosclerotic burden From: “Is there a blockage?” To: “How diseased is the artery overall?” Diffuse coronary disease is real. It has always been there. Now we can see it. That’s the power of Photon-Counting CT in coronary atherosclerosis. ⚡🫀 #PhotonCountingCT #PCCT #CoronaryCTA #Atherosclerosis #NonCalcifiedPlaque #PreventiveCardiology #CardiacCT #RadiologyInnovation #yesCCT
