For best detection which is best digital mammogram or sonogram?

Mammogram: Mammogram remains the first choice for breast cancer screening. There is a select group of patients for whom screening ultrasound and MRI breast will be added to supplement the mammogram.

Mammogram: A mammogram (preferably digital) is still the best screening imaging tool . Ultrasound is not currently used as a universal screening modality. However, it is an excellen adjunct test if there is a clinical, mammographic or MRI abnormality which needs further evaluation. In addition ultrasound is also very effective in targetting a lesion which may need a biopsy if it can be seen by ultrasound.

Mammo/US: Mammo is the standard of care for screening. Mammo is approximately 80% sensitive for detecting breast cancer. Sensitivity decreases in women with dense breasts, some say to as low as 40-50%. There is some data to support adding screening US as a supplement to mammography in women with dense breasts, which can detect an additional 3-5 cancers per 1000 patients. False positives a problem though
