Flat-panel volume computed tomography (fpVCT) is a recent development in imaging. We discuss some of the musculoskeletal applications of a high-resolution flat-panel CT scanner. FpVCT has four main advantages over conventional multidetector computed tomography (MDCT): high-resolution imaging; volumetric coverage; dynamic imaging; omni-scanning. The overall effective dose of fpVCT is comparable to that of MDCT scanning. Although current fpVCT technology has higher spatial resolution, its contrast resolution is slightly lower than that of MDCT (5-10HU vs. 1-3HU respectively). We discuss the efficacy and potential utility of fpVCT in various applications related to musculoskeletal radiology and review some novel applications for pediatric bones, soft tissues, tumor perfusion, and imaging of tissue-engineered bone growth. We further discuss high-resolution CT and omni-scanning (combines fluoroscopic and tomographic imaging).
平板容积计算机断层扫描（fpVCT）是成像领域的一项最新进展。我们讨论了高分辨率平板CT扫描仪在肌肉骨骼方面的一些应用。与传统多排探测器计算机断层扫描（MDCT）相比，fpVCT有四个主要优点：高分辨率成像；容积覆盖；动态成像；全向扫描。fpVCT的总体有效剂量与MDCT扫描相当。虽然目前的fpVCT技术具有更高的空间分辨率，但其对比分辨率略低于MDCT（分别为5-10HU和1-3HU）。我们讨论了fpVCT在肌肉骨骼放射学相关各种应用中的疗效和潜在用途，并回顾了其在儿科骨骼、软组织、肿瘤灌注以及组织工程骨生长成像方面的一些新应用。我们还进一步讨论了高分辨率CT和全向扫描（结合了荧光透视和断层成像）。
