Rad T 275 Mammography

Types of Mammography Diagnostic –Patients with symptoms or risk factors Screening –Asymptomatic patients

Mammography Equipment High frequency generators Target material –Molybdenum –Rhodium –Tungsten FSS –0.1/0.3mm

Mammo Equip cont. Filtration –Inherent 0.1 mm Al eq 23 degree target angle and tube tilt Heel effect –Anode is farthest from the chest wall Compression –Uniform thickness –Reduced OID –Less thickness, less scatter, lower dose

Mammo equip cont. Grids –Moving grids with 4:1 or 5:1 ratios AEC –Necessary due to differences in breast composition

Cyst

Infiltrating duct carcinoma

Duct carcinoma In situ

Cyst

Fibroadenoma Non cancerous

Implant rupture

Invasive ductal and lobular carcinoma PrePost
