主要方法:
- 一项针对89名HCC患者 (94个病变) 的前性研究,这些患者在手术前接受了光谱CT扫描.
- 患者被分为高 (Ki-67>20%) 和低 (Ki-67 ≤20%) 表达组.
- 分析了光谱CT参数,包括CT值,度 (IC),光谱Hounsfield单位 (HU) 曲线 (λHU) 斜率,动脉 (AP) 和门静脉阶段 (PVP) 的正常化度 (NIC) 和细胞外体积 (ECV) 分数.
主要成果:
- 在高基-67组和低基-67组之间发现了内NIC-AP,NIC-PVP,AP斜率,PVP斜率和ECV分数的显著差异.

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...
