The role of ultrasound in breast imaging Dr Francien Malan Drs Van Wageningen & Vennote 31 October 2007
How does ultrasound work? High frequency sound wave Crystal probe serves as both transmitter and detector of sound waves Different tissue types Signal coming back translated into real time black and white picture by computer software
Indications the same as for women without implants Also for evaluation of implant complications such as rupture
Ultrasound guided cyst aspiration/ biopsy Aspiration of cysts are done when cyst has atypical features, pain relief, relief of anxiety, cosmetic reasons Biopsy done when after clinical evaluation/ mammography and ultrasound the nature of lesion is still uncertain
What happens? Outpatient Sterilised, anaethetised Needle is guided into cyst under direct ultrasound vision Cells obtained to path lab for evaluation
Ultrasound guided localisation Localisation is done prior to surgical resection of lesion to guide surgeon to the lesion, can be done with u/s or mammogram Inpatient, fasting, sterile conditions, local anaesthetic, localisation needle guided into lesion, wire strapped to arm, patient goes to theatre.
Lesion visible on ultrasound, not clinically palpable; may or may not be visible on mammogram Benefits of real time guidance of wire into lesion; 3D perspective; relatively quick; Why ultrasound for localisation?
Why mammogram for localisation? Microcalcifications Small lesion deeply seated in large breasts Area of suspicion on mammogram not visible on ultrasound
