概括
全身2-[18F]-氧葡萄糖-正子发射断层扫描与MRI (WB-2-[18F]FDG-PET/MRI) 结合,在诊断燃烧的多发性骨髓瘤 (SMM) 中显示出有前途. 在MRI上,扩散性骨髓参与是SMM患者无进展生存的关键预测因素.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 燃烧的多发性骨髓瘤 (SMM) 是症状多发性骨髓瘤 (MM) 的无症状前体.
- 准确的风险分层对于管理SMM和预测进展到症状MM至关重要.
- 当前的诊断标准可能无法完全捕捉到所有SMM患者的进展风险.
研究的目的:
- 评估WB-2-[18F]FDG-PET/MRI在SMM中的诊断和预后性能.
- 在SMM中检测MM相关的骨髓或骨髓外疾病.
- 在SMM患者中预测无进展生存期 (PFS).
主要方法:
- 对116名接受WB-2-[18F]FDG-PET/MRI的SMM患者进行前性研究.
- 用PET与MRI检测病变的评估.
- 对98名SMM患者进行随访,以确定PFS.
主要成果:
- 核磁共振检测出明显更多的病变 (20%) 比PET (9%) (p=0.02).
- 扩散性骨髓参与 (BMI) 在MRI (53%) 比PET (20%) (p<10-3) 中更为普遍.
- 在MRI上,分散的BMI是PFS最强的不良预后因素 (HR=4.16,p=0.03),识别了高风险的SMM.
结论:
- WB-2-[18F]FDG-PET/MRI对于SMM工作非常有价值.
- 通过MRI检测到的分散骨髓干扰是进展到症状MM的显著预测因素.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
169
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Positron Emission Tomography
5.6K
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...
