Elastografisk
Elastografisk is an adjective used in Swedish and Norwegian to denote elastography, a medical imaging approach that maps tissue stiffness. Elastography provides information about the mechanical properties of tissue, complementing conventional anatomical imaging and aiding in characterizing lesions and disease.
The main modalities are ultrasound elastography and magnetic resonance elastography. Ultrasound elastography includes strain elastography, which
Elastograms display relative stiffness, often with color coding. Areas of increased stiffness may indicate fibrosis, malignancy,
Applications include liver fibrosis staging, where stiffness correlates with fibrosis level; characterization of breast lesions; evaluation
Limitations include variability in accuracy across techniques and devices, operator dependence for some methods, and susceptibility
Safety and accessibility are favorable: elastography is noninvasive and typically does not require ionizing radiation, and
