MR Breast Examination
Breast cancer has become the most common type of cancer in women in Hong Kong since 1994, and ranks third in mortality among all cancer types in women. Early detection is vital to better clinical outcomes. Magnetic resonance imaging (MRI), which utilizes magnetic field to produce signals for image acquisition, is one of the advanced methods for breast cancer examination. It does not involve ionizing radiation, and researches show that MRI performs better in detection of high grade ductal carcinoma in situ (DCIS) and invasive carcinoma.
MR Breast VS 3D Mammogram
|Abbreviated Breast MRI (AB-MRI) Protocol||Digital Breast Tomosynthesis
(also known as “3D-Mammogram”)
|High sensitivity for biologically aggressive disease||Widely adopted and popular imaging tool for breast cancer screening|
|No ionizing radiation||Small amount of ionizing radiation|
|Intravenous gadolinium-based contrast injection is required||No intravenous contrast medium is required|
|Claustrophobia may be experienced by some people||No claustrophobia|
|No compression of breasts is required during the examination, however mild pain may be experienced during the intravenous injection of contrast medium||Mild discomfort due to breast compression during the examination|
|Not suitable for people who have pacemaker or metallic implants inside body||No such limitation|
|Remarks: Both Abbreviated Breast MRI (AB-MRI) protocol and 3D Mammogram have their own distinct purposes, indications, advantages and limitations.
Your doctor will choose the imaging modality, single or in combination, that would be most suitable to you.
