MRI of Breast Lymphoma: A Report of Two Cases with Emphasis on Diffusion Weighted Imaging and Apparent Diffusion Coefficient Value
Breast lymphoma is a rare neoplasm that accounts for approximately 0.04-0.5% of
breast malignancies. Most breast lymphomas are B-cell type non-Hodgkin lymphomas.
The imaging features of breast lymphoma on mammography and ultrasound are nonspecific.
There have been several reports on magnetic resonance imaging characteristics
of breast lymphoma but only few have described features on diffusion weighted
imaging. Herein, we describe the magnetic resonance imaging findings, with emphasis
on diffusion weighted imaging and the apparent diffusion coefficient sequences, of two
cases of breast lymphoma and compare them with the magnetic resonance imaging
features reported in the literature
Comparison of Image Quality Criteria between Digital Storage Phosphor Plate in Mammography and Full-Field Digital Mammography in the Detection of Breast Cancer
Background: Digital mammography is slowly replacing screen film
mammography. In digital mammography, 2 methods are available in
acquiring images: digital storage phosphor plate and full-field digital
mammography. The aim of this study was to compare the image quality
acquired from the 2 methods of digital mammography in the detection of
breast cancer. Methods: The study took place at the National Cancer
Society, Kuala Lumpur, and followed 150 asymptomatic women for the
duration of 1 year. Participating women gave informed consent and were
exposed to 4 views from each system. Two radiologists independently
evaluated the printed images based on the image quality criteria in
mammography. McNemar’s test was used to compare the image quality
criteria between the systems. Results: The agreement between the
radiologists for the digital storage phosphor plate was ĸ = 0.551
and for full-field digital mammography was, ĸ = 0.523. Full-field
digital mammography was significantly better compared with the digital
storage phosphor plate in right and left mediolateral oblique views (P
< 0.05) in the detection of microcalcifications, which are early
signs of breast cancer. However, both systems were comparable in all
other aspects of image quality. Conclusion: Digital mammography is a
useful screening tool for the detection of early breast cancer and
ensures better prognosis and quality of life
