Aim. To analyze sensitivity of magnetic resonance imaging (MRI) in the diagnosis of breast cancer when used after mammography and breast ultrasound.Methods. The study included 70 patients with nonpalpable breast lesions who had changes of breast tissue found at previous studies (mammography and breast ultrasound). MRI was performed with the use of Siemens Magnetom Avanto with magnetic field 1.5 Tl.Results. Most frequently nonpalpable lesions were diagnosed in 45 to 60-year old patients (60%), a little rarer - in 39 to 45-year old patients (22.9%), in patients at the age of 61 to 69 - in 10.0% (7 patients). 7.1% patients were over 70. All first detected nonpalpable lesions of breast were biopsied for morphological verification. With the combined use of mammography, sonography, MRI and stereotactic biopsy the diagnosis was made in 100% patients. MRI with contract enhancement showed no relation between sensitivity, specificity and reliability and density of breast tissues.Conclusions. MRI is considered a highly sensitive method of diagnosis and identification of changes found at mammography and breast ultrasound.

Background: The multifocality and multicentrality of breast cancer (MFMCC) are the significant aspects that determine a specialist’s choice between applying breast-conserving therapy (BCT) or performing a mastectomy. This study aimed to assess the usefulness of mammography (MG), contrast-enhanced spectral mammography (CESM), and magnetic resonance imaging (MRI) in women diagnosed with breast cancer before qualifying for surgical intervention to visualize other (additional) cancer foci. Methods: The study included 60 breast cancer cases out of 630 patients initially who underwent surgery due to breast cancer from January 2015 to April 2019. MG, CESM, and MRI were compared with each other in terms of the presence of MFMCC and assessed for compliance with the postoperative histopathological examination (HP). Results: Histopathological examination confirmed the presence of MFMCC in 33/60 (55%) patients. The sensitivity of MG in detecting MFMCC was 50%, and its specificity was 95.83%. For CESM, the sensitivity was 85.29%, and the specificity was 96.15%. For MRI, all the above-mentioned parameters were higher as follows: sensitivity—91.18%; specificity—92.31%. Conclusions: In patients with MFMCC, both CESM and MRI are highly sensitive in the detection of additional cancer foci. Both CESM and MRI change the extent of surgical intervention in every fourth patient.
