Abstract
This thesis included the study of the role of magnetic resonance
imaging (MRI) examination in the detection and characterization of
malignant tumors of the breast.
The review of literature enclosed the anatomical background of the
breast as well as the pathologic bases of the benign and malignant breast
tumors. The indications of MRl examination of the breast and the MRl
appearance of malignant breast tumors were also revised.
The practical work included the MRl examination of20 cases,
presenting with breast lesions suspicious for malignancy using double
breast coil. The examination protocol included the rapid dynamic imaging
within the first ten minutes after I.V. injection of gadolinum contrast
agent.
The MRl examination was preceded by clinical evaluation of the
cases as well as mammographic and sonographic examination.
The results of this study showed the value ofMRl in increasing
detectability of malignant breast lesions especially in cases of
mammographically dense breasts and recurrent breast tumors as well as
the detection of multicentrcity and breast tumors located near the chest
wall. The thesis showed also the value of delayed imaging after
gadolinium injection in differentiation between benign and malignant
breast tumors on the basis of different morphological and quantitative
signs.
