“…131 Advantages of BCT are full 3D capability, increased accuracy (especially with dense breasts), higher spatial resolution, shorter examination time and costs compared with MRI, 132 and improved patient comfort (no compression), at a radiation exposure comparable to mammography. [133][134][135][136] Typically, patients are scanned in prone position, and the targeted breast is placed through a tabletop opening into a cylindrical cavity. The ipsilateral arm is alongside the body and the contralateral arm up at head level.…”

“…The first studies with a prototype from GE dating back to the late 1970s, but it took until 2015 for the Food and Drug Administration to approve BCT for non–contrast-enhanced breast imaging 131 .

“…The ipsilateral arm is alongside the body and the contralateral arm up at head level. To optimize patient positioning, a leg support can be added, a sandbag placed on the shoulder of the side of the breast to examine, and the ipsilateral arm positioned along the body, palm facing down, while the contralateral arm is elevated to the head 135 . To image the contralateral breast, repositioning of the patient is necessary.…”

Computed tomography (CT) dramatically improved the capabilities of diagnostic and interventional radiology. Starting in the early 1970s, this imaging modality is still evolving, although tremendous improvements in scan speed, volume coverage, spatial and soft tissue resolution, as well as dose reduction have been achieved. Tube current modulation, automated exposure control, anatomy-based tube voltage (kV) selection, advanced x-ray beam filtration, and iterative image reconstruction techniques improved image quality and decreased radiation exposure. Cardiac imaging triggered the demand for high temporal resolution, volume acquisition, and high pitch modes with electrocardiogram synchronization. Plaque imaging in cardiac CT as well as lung and bone imaging demand for high spatial resolution. Today, we see a transition of photon-counting detectors from experimental and research prototype setups into commercially available systems integrated in patient care. Moreover, with respect to CT technology and CT image formation, artificial intelligence is increasingly used in patient positioning, protocol adjustment, and image reconstruction, but also in image preprocessing or postprocessing. The aim of this article is to give an overview of the technical specifications of up-to-date available whole-body and dedicated CT systems, as well as hardware and software innovations for CT systems in the near future.

“…Auf diese Weise können Mammakarzinome besser erkannt, hinsichtlich ihrer Ausdehnung beurteilt und charakterisiert werden, ähnlich wie dies bereits für das Dual-Energy EID-CT berichtet wurde [14,26,27]. Schlussendlich ist im Vergleich zur Mammographie keine Kompression der Brust erforderlich und dementsprechend ein deutlich höherer Patientenkomfort gegeben [28]. Auch wenn die Mammographie weiterhin als Standard-Diagnostik in der Mammabildgebung anerkennt ist, bietet die PCD-CT dennoch vielversprechende neue Möglichkeiten (z.…”

“…In this way, breast carcinomas can be better recognized, assessed, and characterized in terms of their extent, similar to what has already been reported for the Dual-Energy EID CT 14 26 27 . Finally, no compression of the breast is required compared to mammography and, accordingly, a significantly higher level of patient comfort is provided 28 . Even though mammography is still recognized as the standard diagnosis in breast imaging, PCD CT still offers promising new possibilities (e. g., in staging examinations) that should be evaluated in further clinical trials.…”

Background Photon-counting detector computed tomography (PCD-CT) is a promising new technology with the potential to fundamentally change workflows in the daily routine and provide new quantitative imaging information to improve clinical decision-making and patient management. Method The contents of this review are based on an unrestricted literature search of PubMed and Google Scholar using the search terms “photon-counting CT”, “photon-counting detector”, “spectral CT”, “computed tomography” as well as on the authors’ own experience. Results The fundamental difference with respect to the currently established energy-integrating CT detectors is that PCD-CT allows for the counting of every single photon at the detector level. Based on the identified literature, PCD-CT phantom measurements and initial clinical studies have demonstrated that the new technology allows for improved spatial resolution, reduced image noise, and new possibilities for advanced quantitative image postprocessing. Conclusion For clinical practice, the potential benefits include fewer beam hardening artifacts, a radiation dose reduction, and the use of new or combinations of contrast agents. In particular, critical patient groups such as oncological, cardiovascular, lung, and head & neck as well as pediatric patient collectives benefit from the clinical advantages.
