Effect of thyroid shielding during mammography: measurements on phantom and patient as well as estimation with Monte Carlo simulation [0.03%]
乳腺摄影时甲状腺屏护的效果：体模和病人的测量以及蒙特卡罗模拟估算
Miriam Pyka,Patrik Eschle,Christian Sommer et al.
Miriam Pyka et al.
Background: During mammography, the thyroid is exposed to scattered radiation from breast tissue and the device. This may increase the risk of radiation induced thyroid cancer. ...
Cord cross-sectional area at foramen magnum as a correlate of disability in amyotrophic lateral sclerosis [0.03%]
颈椎横截面积作为肌萎缩侧索硬化型残疾的关联因素
Niccolò Piaggio,Matteo Pardini,Luca Roccatagliata et al.
Niccolò Piaggio et al.
Spinal cord atrophy is one of the hallmarks of amyotrophic lateral sclerosis (ALS); however, it is not routinely assessed in routine clinical practice. In the present study, we evaluated whether spinal cord cross-sectional area measured at ...
Radiological findings in ancient Egyptian canopic jars: comparing three standard clinical imaging modalities (x-rays, CT and MRI) [0.03%]
