This review aims to provide a comprehensive overview of the current state of knowledge and the growing body of research literature, illustrating innovative applications and perspectives through case examples.We conducted a structured literature review, identifying relevant studies via Google Scholar and PubMed, using the keywords \"photon-counting detector\", \"cardiovascular CT\", \"cardiac CT\", and \"ultra-high-resolution CT\". We analyzed studies published since January 2015. Additionally, we integrated our own clinical experiences and case examples.In addition to the well-known benefit of increased temporal resolution offered by dual-source scanners, dual-source PCD-CT provides three key advantages: 1) Optimized geometric dose efficiency with an improved contrast-to-noise ratio, 2) intrinsic spectral sensitivity, and 3) the ability for ultrahigh-resolution CT. This technology enables improved image quality or radiation dose reduction in established cardiovascular protocols. Its use in non-invasive cardiac diagnostics for obese patients, those with a high plaque burden, or after stent implantation appears technically feasible, potentially expanding the scope of CT. The spectral sensitivity also allows tailored image acquisition, reducing metallic artifacts and contrast agent doses in patients with renal impairment. Early studies and clinical experience support these potential applications of PCD-CT in cardiovascular diagnostics, suggesting workflow optimization and improved patient management.However, challenges remain, including high costs, large data volumes, somewhat longer reconstruction times, and technical difficulties in combining spectral sensitivity with ultra-high resolution. Prospective randomized studies with clinical endpoints are lacking to confirm the clear advantage over conventional scanners. Future research should focus on endpoint-based studies and robust cost-benefit analyses to evaluate the potential of this technology and facilitate its evidence-based integration in clinical practice. · Photon-counting detector CT represents a technological advancement in computed tomography.. · Spectral sensitivity enhances iodine signal and minimizes artifacts.. · Ultra-high-resolution CT allows precise imaging, even in stents and advanced sclerosis.. · This technology must be validated through endpoint-based, randomized studies.. · Hagar MT, Schlett CL, Oechsner T et al.

{"title":"Performance of fast and ultrafast T2-weighted MRI sequences for common cerebral lesions in children.","authors":"Daniel Gräfe, Rebecca Anders, Jens Frahm, Dirk Voit, Stefan-Horia Simion, Andreas Merkenschlager, Franz Wolfgang Hirsch","doi":"10.1055/a-2404-8674","DOIUrl":"10.1055/a-2404-8674","url":null,"abstract":"<p><p>The use of fast and ultrafast T2-weighted sequences allows for low-motion-artifact imaging of the cerebrospinal fluid spaces and can thus avoid sedation in young children for cranial MRI (cMRI). It is still unclear to what extent these sequences can also depict other common cerebral findings in children. The aim of the study was to compare the potential delineation of common intracranial findings in pediatric cMRI with two fast and one ultrafast T2-weighted sequences.Children who had undergone a single-shot spin-echo and gradient echo sequence, as well as an ultrafast volume coverage (VC) sequence, in addition to a standard T2-weighted fast spin-echo (FSE) sequence as reference were retrospectively included. Visualization of findings was assessed using a Likert scale from 0 to 3. Differences between groups of findings were quantified using a Kruskal-Wallis test.284 findings in 126 patients (median age: 10.6 years, interquartile range: 5.1 to 15.0 years) were analyzed. Overall, in fast T2-weighted sequences, the percentage of visible (score 2 or 3) findings was between 60% and 100%. There was little difference between the two fast sequences and the ultrafast VC.Ultrafast VC as compared to conventional fast sequences allows for almost the same discrimination of common neuropediatric pathologies but at seven times the speed. Although not an equivalent substitute for T2 FSE in parenchymal findings, it can contribute to triage at little expense and thus reduce the burden on both patients and staff. · Fast T2-weighted sequences can depict many types of neuropediatric findings. · They cannot fully replace a T2 fast spin-echo sequence. · An ultrafast volume coverage sequence shows similar quality to conventional fast sequences. · Gräfe D, Anders R, Frahm J et al.
