Diffusion-weighted imaging (DWI) shows promise as an alternative to contrast-enhanced breast MRI for detecting breast cancer. While DWI can visualize lesions and reduce biopsies, its sensitivity is currently lower than contrast-enhanced MRI.
Area of Science:
- Radiology
- Oncology
- Medical Imaging
Background:
- Contrast-enhanced breast magnetic resonance imaging (MRI) is highly sensitive for breast cancer detection.
- Widespread use of breast MRI is hindered by complex procedures and contrast media requirements.
Purpose of the Study:
- To evaluate if diffusion-weighted imaging (DWI) can replace contrast-enhanced sequences for unenhanced breast MRI.
- To assess DWI as a potential standalone or complementary technique in breast MRI protocols.
Main Methods:
- A narrative review of existing literature.
- Meta-analysis of previously published studies on DWI in breast MRI.
Main Results:
- DWI effectively visualizes breast lesions and differentiates benign from malignant findings.
- DWI can serve as a viable alternative to contrast-enhanced sequences and reduce unnecessary biopsies.
- A current disadvantage of DWI is its lower sensitivity compared to contrast-enhanced breast MRI due to robustness issues.
Conclusions:
- DWI is recommended as a component of current clinical breast MRI protocols.
- The use of DWI as a standalone technique in unenhanced breast MRI protocols requires further investigation.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Cell Potential and Free Energy
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...
