MRI for Breast Cancer Evaluation
Northside
Hospital and Northside Radiology Associates,
P.C. are proud to have one of the few imaging programs
in Georgia to offer MRI for breast cancer evaluation. MRI
uses strong magnets and radio waves to image tissues from
multiple angles and create very detailed images. No radiation
is used.
Recent technical advances have made it possible to focus
MRI on the breast to help detect and stage cancer. Contrast
is injected intravenously to highlight abnormal areas and
calculations of blood flow patters are made to determine if
a tumor is present. MRI is not limited by dense tissue, scars,
implants, and other factors which sometimes can interfere
with seeing cancers on mammograms.
Studies have shown MRI to be almost 100% sensitive for detecting
invasive breast cancers. It is proving to be an excellent
tool for evaluating patients diagnosed with breast cancer
– to help with surgical planning, follow up patients
on chemotherapy, and evaluate for possible recurrence. However,
it also highlights many types of findings which are not cancer.
Because of this, patients may need to have additional tests,
follow up MRI, or even biopsy to clear an area.
So far, little research has been done to evaluate MRI for
cancer screening. It has shown promising results in very high
risk patients such as those with known defects in breast cancer
genes, as a complement to mammography and physical exam. It
has not been evaluated for routine screening of most patients
and is not currently recommended for general screening due
to a lack of research, high cost, the requirement for an IV,
and the number of “false alarms” it can cause.
We perform breast MRI evaluations at the Northside
Hospital main campus using a dedicated breast coil and
high resolution imaging sequences (much higher than those
of most systems). Please feel free to contact Dr.
Lynn D. Baxter or Dr. James
F. Zakem at the Northside Hospital
Breast Care Center for further information.
