Sonography
BILATERAL SONOMAMMOGRAPHY images both breasts with ultrasound in the same sitting, rather than focusing on one specific spot. Doctors often use it to look closer at breast tissue that showed up dense on a mammogram, since dense tissue and a tumor can both appear white there and are hard to tell apart. Nearly half of women over 40 getting a mammogram have breast tissue dense enough for this to matter. Ultrasound reads that same tissue differently, using sound waves instead of X-rays, so it can pick out a mass a mammogram missed. Comparing both breasts side by side helps your doctor judge whether a finding on one side is genuinely unusual or simply how your tissue looks.
This scan checks the tissue in both breasts for lumps, cysts, or areas that looked dense or unclear on a mammogram. Your doctor compares one side against the other and notes the size, shape, and texture of anything found, deciding from there whether it needs a biopsy or simply a repeat scan later.
Sonomammography is just the technical name for a breast ultrasound: sono for sound waves, mammo for breast. Bilateral means both breasts get examined in the same visit, not only a side where a concern was already found.
Comparing one breast against the other is genuinely useful information. A patch of tissue that looks slightly irregular on its own can look completely ordinary once your doctor sees the same pattern mirrored on the opposite side. This side-by-side view matters most when the reason for the scan is something general, like dense breast tissue flagged on a mammogram, rather than one specific lump your doctor already felt.
Dense breast tissue and a tumor can both show up as a white area on a mammogram, which makes a tumor hard to spot underneath the surrounding density. Ultrasound builds its image from sound waves bouncing off tissue instead, so it reads that same dense area differently and can catch a mass mammography missed.
A normal result on both sides is reassuring but doesn't replace your regular mammogram schedule. Ask your doctor how the two tests fit together for your own screening plan.
Sonomammography is just another name for breast ultrasound. Sono refers to sound waves and mammo refers to the breast, so the term describes the same kind of test as a breast ultrasound, not a different one.
Comparing both breasts side by side helps your doctor judge whether a finding is genuinely unusual or just how your tissue normally looks. This is especially useful when the reason for the scan is general, like dense tissue on a mammogram, rather than one specific lump.
A mammogram uses low-dose X-rays and reads breast tissue by density. This scan uses sound waves instead, which can pick out a solid mass in tissue that looked uniformly dense on the mammogram.

No. Ultrasound uses sound waves rather than X-rays, so there's no radiation exposure at all.
No. This scan is meant to work alongside your mammogram schedule, not instead of it. Ask your doctor how the two fit together for your own screening plan.
There's no single preparation that applies to every patient. Ask your doctor or the centre directly what they'd like you to do beforehand.
This entry checks both breasts together, often for a general finding like dense tissue on a mammogram. USG BREAST is typically ordered to work up one specific lump or finding already identified on one side.
