In recent years, Photon-counting detector CT (PCD CT) has emerged as a new and groundbreaking technology in clinical radiology. While clinical research and practical applications of PCD-CT are constantly evolving, it has not yet been integrated into post-mortem CT (PMCT) imaging. Documented research into the potential applications of PCD CT in the field of post-mortem human forensic pathology and anatomical pathology is scarce in literature. This is despite the fact that PCD CT shows promise in expanding PMCT imaging diagnostic due to features such as ultra-high resolution and intrinsic spectral multienergy imaging. The authors have recently started scanning forensic corpses with a PCD CT to explore its possibilities and limits in the post-mortem field. In this technical note, the PCD CT acquisition and reconstruction parameters that resulted in excellent image quality in terms of noise and contrast for a slice thickness up to 0.2 mm in unenhanced whole-body examinations are presented.
近年来,光子计数探测器CT(PCD CT)已成为临床放射学中一项全新的突破性技术。尽管PCD-CT的临床研究和实际应用在不断发展,但其尚未被整合到尸检CT(PMCT)成像中。关于PCD CT在死后人体法医病理学和解剖病理学领域潜在应用的文献研究很少。尽管PCD CT由于超高分辨率和固有光谱多能量成像等特性,在扩展PMCT成像诊断方面显示出前景,但情况依然如此。作者最近开始使用PCD CT扫描法医尸体,以探索其在尸检领域的可能性和局限性。在本技术说明中,介绍了在未增强的全身检查中,对于厚度达0.2毫米的切片,在噪声和对比度方面产生优异图像质量的PCD CT采集和重建参数。
