Breast Imaging in Southwestern Montana
We offer several types of breast imaging in affiliation with Advanced Medical Imaging.
Mammograms are x-ray exams of the breast, used to detect and evaluate breast
changes. Screening mammograms can reveal cancers in very early stages
when they are too small to be felt by hand, greatly improving the chance
for successful treatment. Diagnostic mammograms are used to investigate
possible problems and carefully study an area of concern to determine
if further treatment is needed.
Tomosynthesis, or three-dimensional (3D) digital mammography, converts
two-dimensional digital breast images into stacked, very thin slices,
building a 3D mammogram. Overlapping normal breast tissue, especially
if dense, can prevent physicians from seeing cancer on a 2D image. Tomosynthesis
removes the impact of overlapping tissue, and allows radiologists to look
through the tissue, one millimeter at a time, identifying and characterizing
individual breast structures.
Magnetic resonance imaging (MRI) is an imaging tool that uses radiofrequency
waves to create detailed, cross-sectional pictures of the inside of the
body, providing greater contrast within the soft tissues of the body than
a CT scan. Unlike X-rays and CT scans, an MRI does not use radiation.
MRI systems are able to distinguish between normal and diseased tissue,
pinpointing cancerous cells within the body. MRI helps identify tumors
in the breast that may not be visualized on a mammogram.
Ultrasound imaging technology uses high-frequency sound waves to produce
images of organs and tissues within the body without radiation. It can
be used to precisely locate the position of a tumor in order to guide
a biopsy or aspiration procedure. For example, ultrasound may be used
to mark out the boundaries of a tumor prior to its removal. It can also
be used to administer cancer treatments. Ultrasound technology allows
for detection of slight abnormalities in dense breasts and determination
of whether a lump is a cyst (sac containing fluid) or a solid mass.
