“…It has been suggested that MRI is useful for: (1) detecting cancers that are occult clinically and mammographically; (2) assessing lesion size and spread; and (3) differentiating between malignant and benign lesions. [1][2][3][4][5][6][7] Diffusion-weighted imaging has become a common investigation tool and is used extensively in the central nervous system (e.g., for the diagnosis of acute cerebral infarction). 14,15 Recently, DWI has been increasingly applied to breast imaging following development of the parallel imaging technique.…”

“…Previous studies reported that MRI enabled the detection of breast cancer that was occult on mammography and US. [1][2][3][4][5][6][7] Recently, diffusion-weighted imaging (DWI) has been applied increasingly to the body as well the central nervous system. DWI of the breast is expected to have clinical potential because of its high sensitivity.…”

Our need to create a program for individuals at high risk for breast cancer development led us to research the available data on such programs. In this paper, we summarize our findings and our thinking process as we developed our own program.Breast cancer incidence is increasing worldwide. Even though there are known risk factors for breast cancer development, approximately 60% of patients with breast cancer have no known risk factor, although this situation will probably change with further research, especially in genetics. For patients with risk factors based on personal or family history, different models are available for assessing and quantifying risk. Assignment of risk levels permits tailored screening and risk reduction strategies. Potential benefits of specialized programs for women with high breast cancer risk include more cost -effective interventions as a result of patient stratification on the basis of risk; generation of valuable data to advance science; and differentiation of breast programs from other breast cancer units, which can result in increased revenue that can be directed to further improvements in patient care.Guidelines for care of patients at high risk for breast cancer are available from various groups. However, running a high-risk breast program involves much more than applying a guideline. Each high-risk program needs to be designed by its institution with consideration of local resources and country legislation, especially related to genetic issues. Development of a successful high-risk program includes identifying strengths, weaknesses, opportunities, and threats; developing a promotion plan; choosing a risk assessment tool; defining “high risk”; and planning screening and risk reduction strategies for the specific population served by the program. The information in this article may be useful for other institutions considering creation of programs for patients with high breast cancer risk.

This study included thirty three patients with suspicious breast lesions. For every patient; Mammography, Ultrasonography and Dynamic MRI were done.Our results indicate that the sensitivity of breast imaging can be increased by complementary use of MRI. For patients in whom the status of breast lesion remains unclear, MRI, though most expensive among all other complementary diagnostic modalities, it reduces the number of unnecessary biopsies and diagnostic challenges.

Citation MethodsMammography was conducted for all patients using digital mammography in both medio lateral oblique and craniocaudal views with spot compression magnification view when necessary.Mammographic images were analyzed regarding the presence of masses, architectural distortion, asymmetrical density and calcification. In detected masses their side, site, number, margins and density were evaluated, while in case of micro calcification their shape and distribution were assessed.Then classification of breast lesions was based on the Breast Imaging Reporting and Data System (BI-RADS).Then ultrasound was performed for all patients using a high frequency probe (7.5MHZ), scanning was done in two orthogonal (longitudinal and transverse) planes.Masses were evaluated by US considering BI-RADS US lexicon regarding: their shape, orientation, margins, echopattern (anechoic, hyperechoic, complex, hypoechoic, isoechoic), lesion boundary (abrupt interface, echogenic halo) and presence or absence of acoustic shadowing or enhancement.Then all patients were referred for further MRI examination. MR imaging protocolDynamic MR imaging was performed with high field strength 1.5 Tesla on (Philips Ingenia system) using dedicated double breast coil.Coronal T1 weighted spin echo sequence was carried out for localization purpose and followed by plain sequences using T1weighted fast spin echo sequence (TR=125msec.,TE= 5.3msec.),in addition to T2 weighted fast spin echo sequence (TR=3740mesc.,TE=90 msec.) in axial orientation.A bolus of gadolinium dimeglumine (Gd-DTPA) (Magnavist, Schering AG Berlin, Germany) was injected manually intravenous at a dose of (0.1mmol/kg) followed by saline flush to ensure that contrast -enhanced images could be obtained immediately after contrast agent injection.Dynamic T1 WIs then performed using Gradient echo T1 weighted image with fat suppression at the following time points: 1 minute, 2 min., 4 min. and 7 min.Post processing image subtraction was obtained between the post contrast imaging showing maximum enhancement and pre-contrast images (in the same axial plane), using the software subtraction function available on the work station.Quantitative analysis was done by placing the region of interest (ROI) at the most enhanced part within the lesion result in automatically created time/ signal...
