Analog vs. Digital Mammography
Analog mammography uses X-ray to record images on film using an X-ray
cassette. Films are then "developed" and produced and put on
a light box and read by the radiologist. With digital mammography the
X-rays produce a digital image on a screen while the patient is still
in position. The technologist has the ability to review these in "real
time" to determine image quality. Once completed the images are sent
to the radiologist electronically at a reading station where they can
manipulate, view and magnify areas of breast tissue. This enhances the
information available for reading and interpretation. From the patient’s
perspective there is little difference because the exam is conducted in
a similar way except that the exam is shorter in length. Compression of
the breast is required for both digital and analog mammography.
Is digital a better technology?
While analog mammography is still a sound and reliable exam, digital mammography
offers a new ability to process and view the images. This results in shorter
exam time for the patient, and greater flexibility for the radiologist
in interpreting the images. Much like a digital photo, the images can
be enhanced, manipulated, and improved by the radiologist, so a digital
mammogram can provide more information for diagnosis. Digital technology
also offers better visibility of the entire breast. The capabilities of
digital mammography result in fewer repeat views, which means less patient
exposure, faster exam times, more comfortable and more convenient.
What if I have dense breasts?
If you have dense breast tissue, it is likely that digital mammography will provide better imaging quality for you with reduced radiation dose. This will be reviewed based upon your history and previous mammograms.
Does my insurance cover digital mammography and digital CAD?
The coding and payment
rates are different for analog and digital mammography. Medicare and most
managed care/HMO plans cover digital mammography.
As with any exam, you are advised to check with your insurance company
prior to coming for your mammogram.
iCAD
iCAD is short for Computer Assisted Diagnosis. It is actually a "second radiologist", this system provides a second, computer-assisted opinion to every mammogram that our radiologists read. iCAD will aide in the detection of more breast cancers at an earlier and more treatable stage and give you greater assurance than ever that your normal mammogram is truly normal. CAD improves early detection rates by as much as 23%. It can alert the physician to take a closer look at subtle warning signs that may be easily missed.
When will I learn the results of my Digital Mammogram?
Once your exam is complete,
a radiologist will carefully evaluate the images and meticulously compare
your current mammogram with prior exams in looking for any slight change.
A written report of your results will be sent to your physician’s
office upon dictation. The patient will also receive a letter from Ardsley
Radiology within seven days of their test. If the patient should require
a follow-up diagnostic examination, the radiologist will ensure that all
necessary studies are performed to develop a conclusion. We will discuss
the findings with the patient before they leave. The results will also
be given to the patient in writing, and the physician will receive an
auto faxed report immediately.
What do you have to do?
The day of the exam,
please do not apply
- Lotions
- Deodorant
- Powder
- Perfume
Wear comfortable two piece clothing. Bring previous mammography studies for comparison.
This exam may not be performed if you are pregnant. Consult your physician prior to your exam.
After your mammogram
is taken at Ardsley Radiology the digital image is reviewed by a Computer
Assisted Diagnosis (CAD) System. Helped by its computer analysis, the
radiologist reads the exam and a report is generated and sent to the referring
physicians office via Autofax. A hard copy of the report is also mailed.
