High resolution imaging of craniofacial bone specimens by flat-panel volumetric computed tomography
چکیده انگلیسی

SummaryIntroductionThe prototype flat-panel volumetric computed tomograph (fpvCT) provides a new 3D imaging technology with detailed high resolution by using large-area flat-panel X-ray detectors. The object of this study was to evaluate the benefit of high resolution imaging using the experimental fpvCT to visualise different types of human craniofacial bone pathology. The study proved the feasibility of performing an intraoperative evaluation of free margins in bone malignancies using fpvCT.Material and methodsIn this study, 35 bone specimens of various pathological types were examined by fpvCT. fpvCT data were compared with pre-operative multislice clinical CT images as well as with post-operative histological findings.ResultsBone tumours can be visualised with their specific pathological architecture and infiltration structure faster and more precisely by fpvCT than by multislice CT. The analysis of the resection margins supports the surgical procedure intraoperatively, especially when an immediate reconstruction with bone transplantation is carried out.DiscussionThe fpvCT has a superior image quality when compared with clinical CT systems. The imaging of the bone structure itself has been shown to be useful for the interpretation of osseous resection borders. Furthermore, it can facilitate the diagnosis of tumour progression, especially in areas that are difficult to access, such as the base of the skull.
