Abstract
Ultrasonography examination of the breast has been found to · be one of the new promising
modalities in the diagnosis of different breast lesions.
The aim of this work was to highlight the current role of , ultrasonography in diagnosis
of different breast lesions in order to reach the proper diagnosis and staging of the
disease, decrease the number of biopsies performed for benign solid masses and making
rapid and early detection of malignant lesions before its dissemination. This helps the
surgeon to deal with different patients according to their urgency.
Ultrasonography has the advantages over mammography in: differentiating cystic from solid
lesions, detection of occult lesions in dense breast which is seen in (adolescents, pregnant
women, lactating females and patients with peau d’orange skin with inability to feel a mass),
detection of peripherally located . lesions in areas that can not be correctly
imaged with mammographic views, diagnosis of inflammatory breast diseases when
adequate compression may not be achieved due to tenderness and distinguishing breast cancer
from benign . breast lesions.
The idea of colour and power Doppler ultrasonography by which differentiation between benign and
malignant breast lesions is achieved by detecting the neovascularization of the tumours which are
typically tortuous and showing the characteristic malignant spectral analysis.
Both show great advantage in detecting masses not seen in mammography and can change the diagnosis
of benign masses on mammography to malignant one.
They are useful in differentiation between a malignant lesion in the breast causing edema of the
upper limb due to obstructive metastasis to the upper limb lymphatic from upper limb edema due to
subclavian vein thrombosis.
Also colour and power Doppler ultrasonography are accurate methods of diagnosing local extension as
well as distant extension in axillary, supraclavicular and internal mammary groups of lymph nodes.
Power Doppler ultrasonography based on total integrated power of the Doppler spectrum is now
considered superior to colour Doppler ultrasonography in the demonstration of vascular flow
because of such advantages as high sensitivity to slow flow, no angle dependency.
Recently, MRI has been investigated as a new method for breast 1magmg. Its role 1s only
complementary to mammography and ultrasonography. Due to its high sensitivity it is of great use
in: detection of very small lesions, differentiation of surgical scar from carcinoma on post
treatment mammograms and investigation of breast implants. However, its inability to detect
calcifications provides strong disadvantage in addition to its high cost.
At last the use of ultrasonography, colour and power Doppler ultrasonography are techniques which
can provide non invasive accurate early detection and staging of cancer breast.
