Summary
Ultrasonic elastography, using elastography scores and strain rate ratios, shows significant value in diagnosing small breast cancers (less than 10 mm). This imaging technique aids in identifying malignant breast foci.
Area of Science:
- Medical Imaging
- Oncology
- Diagnostic Ultrasound
Background:
- Early detection of small breast cancers is crucial for effective treatment.
- Accurate differentiation between benign and malignant breast lesions remains a clinical challenge.
Purpose of the Study:
- To evaluate the diagnostic utility of elastography score and strain rate ratio for small malignant breast foci (<10 mm).
Main Methods:
- Retrospective analysis of 22 patients with small breast malignant foci.
- Assessment of ultrasound characteristics, including elastography scores and strain rate ratios.
Main Results:
- Elastography scores ranged from 3 to 5, with most malignant foci scoring 4 or 5.
- The average strain rate ratio was 4.76, showing a correlation with elastography scores.
Conclusions:
- Ultrasonic elastography demonstrates significant value in the diagnosis of small breast cancers.
- Elastography parameters can aid in the characterization of small malignant breast lesions.

01:15Relation between Poisson's ratio, Modulus of Elasticity and Modulus of Rigidity
Deformation occurs in axial and transverse directions when an axial load is applied to a slender bar. This deformation impacts the cubic element within the bar, transforming it into either a rectangular parallelepiped or a rhombus, contingent on its orientation. This transformation process induces shearing strain. Axial loading elicits both shearing and normal strains. Applying an axial load instigates equal normal and shearing stresses on elements oriented at a 45° angle to the load axis.
01:15Strain and Elastic Modulus
The quantity that describes the deformation of a body under stress is known as strain. Strain is given as a fractional change in either length, volume, or geometry under tensile, volume (also known as bulk), or shear stress, respectively, and is a dimensionless quantity. The strain experienced by a body under tensile or compressive stress is called tensile or compressive strain, respectively. In contrast, the strain experienced under bulk stress and shear stress is known as volume and shear...
01:10Stress-Strain Diagram
A stress-strain diagram is a crucial tool that graphically displays a material's mechanical characteristics. This diagram is derived from a tensile test performed on a carefully prepared cylindrical specimen. The specimen has two gauge marks inscribed on its central part, and the distance between these marks is known as the gauge length. The cylindrical specimen is placed in a testing machine, which applies an increasing centric load. As this load grows, so does the gauge length. This change in...
01:20Spearman's Rank Correlation Test
Spearman's rank correlation test, also known as Spearman's rho, is a nonparametric method for assessing the strength and direction of association between two variables. This test is particularly valuable when the data distribution is unknown or when the assumption of normality does not hold. Named after the English psychologist and statistician Dr. Charles Edward Spearman, it serves as the nonparametric counterpart to Pearson's correlation coefficient.

01:20Elastic Strain Energy for Shearing Stresses
As discussed in previous lessons, strain energy in a material is the energy stored when it is elastically deformed, a concept crucial in materials science and mechanical engineering. This energy results from the internal work done against the cohesive forces within the material. When a material undergoes shearing stress and corresponding shearing strain, the strain energy density, which is the energy stored per unit volume, is calculated. Within the elastic limit, where the stress is...
01:27Measurements of Strain
Strain quantifies the deformation of a material under force, typically measured as normal strain, which represents the change in length when compared with the original length. Electrical strain gauges are used for enhanced accuracy. These devices consist of a conductive wire mounted on a paper backing that adheres to the material's surface. These gauges operate on the piezoresistive effect, where the wire's electrical resistance changes in response to mechanical deformation. The strain gauge...
