(2025) Hartung | Ultra-hochauflösende vs Standardauflösende PCCT-Angiographie zur Bildgebung von Femoralstents
Ultra-hochauflösende (UHR) PCCT lieferte eine bessere subjektive Bildqualität als standardauflösende (SR) PCCT für die Femoralstent-CTA, während die Sichtbarkeit des Stentlumens selbst zwischen den Modi vergleichbar blieb. Die Studie verwendete ein perfundiertes menschliches Kadaver-Oberbeinmodell mit 7 oberflächlichen…

(2024) Augustin | Sharp-kernel PCCT verbessert die CTA der unteren Extremitäten im Vergleich zu DSA
Bei 39 Patienten mit 45 Untersuchungen des Abflusses der unteren Extremitäten wurde die PCCT-Angiographie direkt mit der digitalen Subtraktionsangiographie (DSA) bei peripherer arterieller Verschlusskrankheit verglichen. Die Kohorte war herausfordernd, da 77,8 % der Studien die Fontaine-Stufe IV darstellten, was schwere…

(2026) Huflage | Comparison of IMAR presets for UHR angiography for total kneeendoprosthesis
* Among all seven available iterative metal artifact reduction (IMAR) presets, the IMARDental preset unexpectedly provided the strongest reduction of metal artifacts around total knee endoprostheses during ultra-high-resolution photon-counting CT angiography. * IMARDental significantly improved objective artifact reduction…

(2026) Abel | Tin-filtered PCCT improves metal artifact reduction after ACDF
Combining 120 keV virtual monoenergetic imaging (VMI120) with iterative metal artifact reduction (iMAR) achieved the strongest reduction of metal artifacts after anterior cervical discectomy and fusion (ACDF), particularly around titanium implants. Despite superior artifact suppression, standard polychromatic PCCT images…

(2026) Steenbeek | PCCT improves interrater agreement in COCD vs CT
PCCT showed higher interrater agreement than conventional CT for key structural features in capitellar osteochondritis dissecans. The number of loose bodies and the presence of an osseous bridge demonstrated significantly improved agreement with PCCT compared to conventional CT. Despite higher spatial resolution, several…

(2024) Marth | PCCT vs EID-CT of the lumbar spine
Use tin-prefiltered PCCT to reduce lumbar spine dose while preserving subjective image quality. The authors found markedly lower dose with PCCT, while overall subjective image quality remained unchanged versus tin-filtered EID-CT. Expect higher bone-to-fat contrast efficiency with PCCT. Compared with EID-CT, PCCT showed…

(2023) Schreck | Metal artifact reduction in THR with PCCT VMIs
Select ~110 keV VMI for optimal artifact reduction. The authors identified 110 keV as the best balance, achieving strongest reduction of hypo- and hyperdense artifacts without overcorrection. Use 110 keV specifically to improve peri-prosthetic bone assessment. Qualitative ratings showed significantly improved evaluation of…

(2023) Rau | PCCT of the spine improves confidence and lowers dose
PCCT of the spine provided higher sharpness and lower image noise than EID-CT at a clearly lower radiation dose. In patients with metallic implants, 130 keV monoenergetic reconstructions further improved image quality, artifact reduction, and diagnostic confidence compared with standard PCCT reconstructions. PCCT appears…

(2023) Rau | PCD-CT verbessert die Bildqualität und senkt die Dosis bei Multiplen Myelom
Ganzkörper-PCCT lieferte bei Patienten mit Multiplem Myelom eine signifikant bessere subjektive und objektive Bildqualität als die Standard-EID-CT. Die Bildqualität verbesserte sich in Bezug auf die Gesamtbildqualität, Kantenschärfe, Bildrauschen, Läsionssichtbarkeit und diagnostische Sicherheit, während die Strahlendosis…
