量化11C-胆积累的最大标准化吸收值 (SUVmax).
通过免疫染来评估CKα表达强度.

主要成果:

在CKα表达和11C-胆积累之间发现了显著的正相关性 (P < 0.0001).
强的CKα表达与乳腺癌死亡率增加和生存时间缩短有关 (P < 0.0001).
更高的11C-胆积累也与患者的存活率负相关 (P < 0.0001).

结论:

在乳腺癌中,CKα表达与11C-胆积累有很强的相关性.
无论是CKα表达和11C-胆吸收都是乳腺癌的显著预后指标.
这些发现表明,CKα和胆PET成像可以帮助预测瘤活动和患者的结果.

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
