We study two state of the art deep generative networks, the Introspective Variational Autoencoder and the Style-Based Generative Adversarial Network, for the generation of new diffusion-weighted magnetic resonance images. We show that high ...
Superficial fibromatosis: MRI radiomics and T2 mapping correlate with treatment response [0.03%]
浅表纤维瘤病的MRI影像组学及T2图谱与治疗反应相关性研究
Amrutha Ramachandran,Terry Fox,Aaron Wolfson et al.
Amrutha Ramachandran et al.
Background: Superficial fibromatosis exhibits variable MR signal intensity due to collagenous and fibroproliferative components. Quantifying this signal heterogeneity using image texture analysis and T2-mapping could have...
Tissue characterization using R1rho dispersion imaging at low locking fields [0.03%]
低锁定场R1p散射成像技术在组织特征表征中的应用研究
