Mammography Guide

Feb

Overview

Mammography uses low dose x rays to image the breast. It is the standard tool for breast cancer screening. It detects early lesions before they are palpable.

Screening Programs

Regular screening reduces mortality from breast cancer. Programs vary by age and risk factors. Patient education improves participation.

Diagnostic Mammography

Diagnostic mammography evaluates symptoms and abnormal screening results. It includes additional views and magnification. It guides biopsy and management decisions.

Tomosynthesis

Digital breast tomosynthesis provides three dimensional imaging. It improves lesion detection and reduces tissue overlap. It is increasingly used in clinical practice.

Mammography Unit

Feb

Overview

A mammography unit acquires high resolution images of the breast for screening and diagnosis. Units support digital mammography and tomosynthesis techniques. Proper positioning and compression are key to image quality.

Tomosynthesis Capability

Tomosynthesis acquires multiple angled projections to create a three dimensional dataset. It reduces tissue overlap and improves lesion detection in dense breasts. Reconstruction algorithms generate slice images for review.

Quality Control

Regular phantom testing and detector calibration maintain image consistency. Compression device checks and detector uniformity tests are part of QA. Accreditation programs require documented QC procedures.

Patient Comfort and Safety

Compression paddles and ergonomic design improve patient comfort during imaging. Radiation dose is minimized through optimized exposure settings. Clear communication reduces anxiety and improves cooperation.

Mammography Screening and Diagnostic
4
Feb

Overview

Mammography uses dedicated low dose x ray systems and compression to visualize breast tissue and detect calcifications and masses.

Technique

Digital mammography and tomosynthesis three dimensional mammography improve lesion detection. Positioning and compression are critical for image quality.

Clinical Uses

Screening and diagnostic mammography assessment of palpable masses and guidance for breast biopsy.

Limitations and Safety

Sensitivity decreases in dense breasts. Supplemental ultrasound or MRI may be indicated for high risk or dense tissue.

Digital Breast Tomosynthesis DBT

Feb

Overview

DBT acquires multiple low dose projections during a sweep to reconstruct thin slices improving lesion conspicuity over two dimensional mammography.

Technique

Reconstruction algorithms and slice thickness affect detection. DBT is often combined with synthetic two dimensional images to reduce dose.

Clinical Uses

Used for screening and diagnostic workup to reduce recall rates and improve cancer detection in dense breasts.

Limitations and Safety

Slightly higher dose than standard two dimensional mammography. Interpretation requires training and workflow adjustments.
