Bei 58 Säuglingen <10 kg lieferte die kardiale PCCT bei 70 kV und 120 kV vergleichbare Bildqualität, mit ähnlichem aortalen CNR und medianen subjektiven Bildqualitätswerten von 5/5 in beiden Gruppen. 70 kV reduzierte die Strahlendosis um fast 50 %, wobei der CTDI von 0,25 mGy bei 120 kV auf 0,13 mGy bei 70 kV sank…
PCCT achieved lower radiation dose and higher signal-to-noise ratio (SNR) than energy-integrating CT across pediatric head phantom models, demonstrating improved dose efficiency for neuroimaging. The greatest radiation dose reduction was observed in the 10-year-old phantom (9% lower CTDIvol at clinically relevant IQL 200),…
mCTA as the default decision tool: Multiphase CTA replaces binary CTA/CTP thinking by providing sufficient flow dynamics and collateral information for most stroke patients, enabling fast, confident triage without routine perfusion imaging. Head‑to‑heart imaging in the acute phase: Extending the first arterial mCTA phase…
For routine pediatric abdomen PCCT, start with Quantum mode at 70 kV and low-keV VMI rather than defaulting to QuantumPlus. Based on their phantom work, the authors favor the lowest tube voltage as the ALARA-oriented starting point, and for their standard protocol they selected 70 kV Quantum mode with VMI 53 keV. Optimize…
Compared to conventional EID-CT, PCCT enabled a reduction in effective dose of around 90%. PCCT provided noticeably sharper delineation of lung nodules and masses. Overall image quality and visualization of lung nodules were superior with PCCT compared to standard CT. Access full publication Figure 4. Matched axial CT…
