Masking and Demasking Agents

3.1K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

Synthesizing medical images improves MRI diagnostics by creating missing contrasts. Our novel multi-stream approach enhances image synthesis, outperforming existing methods for better diagnostic information.

Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Radiology

Background:

  • Multi-contrast MRI protocols offer rich morphological information for diagnosis.
  • Scan time and patient motion limit the number and quality of MRI contrasts.
  • Image synthesis can generate missing contrasts from existing high-quality MRI data.

Purpose of the Study:

  • To develop an advanced multi-stream approach for synthesizing magnetic resonance imaging (MRI) contrasts.
  • To improve the quality and quantity of diagnostic information in MRI by overcoming limitations of current protocols.

Main Methods:

  • Proposed a novel multi-stream deep learning architecture for MRI synthesis.
  • Integrated multiple one-to-one and a many-to-one synthesis streams.
  • Employed an adaptive fusion block to combine complementary and shared feature maps for enhanced performance.
