Breast MRI provides high sensitivity for cancer detection and extent assessment. It is used for high risk screening problem solving and preoperative planning. MRI complements mammography and ultrasound in comprehensive care.
Indications include high risk screening evaluation of extent of disease and implant assessment. MRI is used when other modalities are inconclusive or in dense breasts. Contrast enhanced protocols improve lesion detection.
Dynamic contrast enhanced sequences and kinetic analysis aid characterization. Background parenchymal enhancement affects sensitivity and specificity. Standardized reporting supports clinical decisions.
MRI is resource intensive and may have limited availability. False positives and cost are considerations in screening use. Shared decision making guides appropriate utilization.
Digital breast tomosynthesis acquires multiple projection images to create a three dimensional dataset. It reduces tissue overlap and improves lesion detection. It is used in screening and diagnostic settings.
Tomosynthesis increases cancer detection and reduces recall rates. It is particularly useful in dense breast tissue. Integration with conventional mammography enhances assessment.
Acquisition parameters and reconstruction affect image quality. Radiologists review slice images to identify subtle findings. Workflow adjustments accommodate additional image review time.
Tomosynthesis may be combined with synthetic mammography and contrast enhanced techniques. Ongoing studies evaluate screening outcomes and cost effectiveness. Adoption continues to grow in many centers.
Cardiac CT provides non invasive assessment of coronary arteries and cardiac structures. It is used for calcium scoring and coronary CT angiography. It aids in risk stratification and procedural planning.
ECG gating and dose modulation optimize cardiac CT studies. Contrast timing and bolus tracking improve coronary opacification. Heart rate control may be used to improve image quality.
Indications include chest pain evaluation and pre procedural planning. Cardiac CT helps assess coronary anomalies and bypass grafts. It complements functional testing and invasive angiography.
Radiation dose and contrast nephropathy are considerations in cardiac CT. Patient selection and protocol optimization mitigate risks. Alternative modalities may be preferred in some patients.
An anti scatter grid reduces scattered radiation reaching the detector to improve image contrast. Grids are used for thicker body parts and higher kV exposures. Proper alignment prevents grid cutoff artifacts.
Linear crossed and focused grids offer different scatter rejection and alignment characteristics. Grid ratio and frequency influence scatter suppression and exposure requirements. Selection depends on clinical application and detector type.
Grids must be handled carefully to avoid bending and damage. Regular inspection for warping and lead strip damage prevents artifacts. Cleaning protocols maintain grid integrity without damaging the structure.
Digital detectors may require specific grid configurations to avoid moire patterns. Grid removal or software based scatter correction are options for certain workflows. Vendor guidance ensures optimal pairing of grid and detector.
