Photon-counting CT (PCCT) offers advantages in terms of noise reduction, higher spatial resolution, and inherent spectral information. PCCT available today allows NCCT to be performed with tube voltage of 120 or 140 kVp. This study evaluates the impact of tube voltage on image quality at an equivalent dose.Methods76 patients with an NCCT with 120 kVp, 76 with 140 kVp, and 56 patients with slightly different effective tube current per group were included. Signal, noise, signal-to-noise ratio, gray-white contrast, and contrast-to-noise ratio were determined using several regions of interest for different virtual monoenergetic image (VMI) levels and compared between dose-equivalent groups. An image quality rating of the clinically used virtual monoenergetic images (VMIs) 65 keV was performed.ResultsThe VMI 65 keV images at 120 kVp exhibited reduced noise, improved gray-white contrast, and improved contrast-to-noise ratio compared to 140 kVp (<i>p</i> < .001). The density differences between cortical gray matter at different distances from calvaria were also lower with 120 kVp (<i>p</i> < .001). The rating of image quality showed no difference between 120 kVp and 140 kVp.ConclusionsCurrently, NCCT with a tube voltage of 120 kVp versus 140 kVp seems to achieve better image quality. However, further studies are required to evaluate possible advantages of 140 kVp, for example artifact reduction in the case of dense foreign materials or enhanced spectral possibilities, and regarding imaging of special intracranial pathologies.</p>","PeriodicalId":47358,"journal":{"name":"Neuroradiology Journal","volume":" ","pages":"19714009251339079"},"PeriodicalIF":1.3,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12037531/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144024489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Timely intervention is crucial, especially in cases involving distal vertebral artery stenosis. <b>Case Report:</b> A 65-year-old male presented with acute vertigo, dizziness, and visual disturbances, along with ipsilateral sixth cranial nerve palsy. His medical history included a treated abdominal aortic aneurysm, hypercholesterolemia, and hypertension. CT angiography (CTA) revealed an occlusion in the V4 segment of the right vertebral artery. CT perfusion imaging showed minimal perfusion delay in the right brainstem. The patient received intravenous thrombolysis (IVT) with tenecteplase, followed by mechanical thrombectomy (MT), partial recanalization was achieved. However, digital subtraction angiography (DSA) identified a critical stenosis (>90%) responsible for the occlusion, consistent with arteriosclerotic disease. Following intravenous administration of 500 mg acetylsalicylic acid, a Biotronik Orsiro 2.25 × 9 mm drug-eluting stent was placed, achieving complete recanalization (eTICI 3). Neurologic symptoms resolved completely post-intervention, and the patient received 300 mg clopidogrel. He was discharged with an MRS score of 0 within 3 days. <b>Conclusion:</b> This case highlights the effectiveness of a multimodal approach (IVT, MT, and stenting) in treating distal vertebral artery occlusion (Mori Type C). Early diagnosis and timely endovascular intervention led to rapid symptom resolution and complete neurological recovery. Follow-up ultrasound at 4 months confirmed good bilateral vertebral artery perfusion without restenosis, supporting the potential long-term benefits of this multimodal treatment approach.

Data were gathered from CT scans performed at the time of admission and 6 hours later, and subsequently analyzed. The data was divided into three cohorts: all cases, adults, and pediatrics.

Through a rigorous process of parameter optimization and K-fold cross-validation, focusing on the area under the receiving operating curve (AUROC), we identified the best models in all cohorts.
