Journal ArticleDOI
Photon-counting CT: Technical Principles and Clinical Prospects.
TL;DR: The authors will explain the technical principles of photon-counting CT in nonmathematical terms for radiologists and clinicians to create opportunities for quantitative imaging relative to current CT technology.
Journal ArticleDOI
Abdominal Imaging with Contrast-enhanced Photon-counting CT: First Human Experience
Amir Pourmorteza,Rolf Symons,Veit Sandfort,Marissa Mallek,Matthew K. Fuld,Gregory Henderson,Elizabeth C. Jones,Ashkan A. Malayeri,Les R. Folio,David A. Bluemke +9 more
TL;DR: The performance of PCD showed no statistically significant difference compared with EID when the abdomen was evaluated in a conventional scan mode, and PCD provides spectral information, which may be used for material decomposition.
Journal ArticleDOI
Photon-counting CT for simultaneous imaging of multiple contrast agents in the abdomen: An in vivo study
Rolf Symons,Bernhard Krauss,Pooyan Sahbaee,Tyler E. Cork,Manu N. Lakshmanan,David A. Bluemke,Amir Pourmorteza +6 more
TL;DR: Photon‐counting spectral CT allowed simultaneous material decomposition of multiple contrast agents in vivo and tissue enhancement at multiple phases was observed in a single CT acquisition, potentially obviating the need for multiphase CT scans and thus reducing radiation dose.
Journal ArticleDOI
Feasibility of Dose-reduced Chest CT with Photon-counting Detectors: Initial Results in Humans.
Rolf Symons,Amir Pourmorteza,Veit Sandfort,Mark A. Ahlman,Tracy Cropper,Marissa Mallek,Steffen Kappler,Stefan Ulzheimer,Mahadevappa Mahesh,Elizabeth C. Jones,Ashkan A. Malayeri,Les R. Folio,David A. Bluemke +12 more
TL;DR: Initial human experience with dose-reduced PCD chest CT demonstrated lower image noise compared with conventional EID CT, with better diagnostic quality and lung nodule CNR.
Journal ArticleDOI
Photon-Counting Computed Tomography for Vascular Imaging of the Head and Neck: First In Vivo Human Results
Rolf Symons,Daniel S. Reich,Mohammadhadi Bagheri,Tyler E. Cork,Bernhard Krauss,Stefan Ulzheimer,Steffen Kappler,David A. Bluemke,Amir Pourmorteza +8 more
TL;DR: Image quality of a spectral photon-counting detector (PCD) computed tomography (CT) system for evaluation of major arteries of the head and neck compared with conventional single-energy CT scans using energy-integrating detectors was evaluated.
