| 中文摘要: |
| 光子计数探测器(PCD)CT具有优异能谱成像能力和高空间分辨率,逐步用于影像学评估肝脏、胰腺、肾脏及胃肠道等腹部脏器,可在降低碘对比剂用量和辐射剂量的同时显著提高腹部微小病变及低对比度病灶检出率。本文就PCD-CT技术特点、临床应用及其腹部成像进展进行综述。 |
| 英文摘要: |
| With excellent energy spectrum imaging capabilities and high spatial resolution, photon counting detector (PCD)-CT is gradually applied in imaging evaluation on abdominal organs, including livers, pancreas, kidneys, gastrointestinal tract and so on, significantly improve the detection of small abdominal lesions and low-contrast abnormalities while reducing both iodine contrast agents dosage and radiation exposure. The technical characteristics and clinical applications of PCD-CT, as well as its advancements in abdominal imaging were reviewed in this article. |
