Optimised compression and exposure techniques have reduced the discomfort and radiation dosage to a minimum. Mammography is recommended as a baseline procedure for all women over 35 years. It should be followed by studies every two years in women between 40-50 years and yearly studies thereafter. Further characterising of these masses is required to avoid unnecessary biopsies and surgery. Towards this end high resolution.
Sonography forms an invaluable and integral part of the examination.
Masses can be separated into solid and cystic types. Cystic masses are less likely to be malignant and more amenable to aspiration and cytology. Other indications are young patients dense breasts, lactating engorged breasts, pregnant patients, acute mastitis, post radiotherapy and surgery and masses which cannot be placed within the field of mammography. However despite its obvious value being operator dependant time consuming and its inability to compare it cannot be used as a screening procedure. It is definitely well placed as a 'trouble shooter'.
