[MR mammography of fatty tissue necrosis].

Purpose: To evaluate MR-imaging for the differentiation of fatty necrosis (FN) of the breast.

Material And Methods: In 1016 MR mammographies FN was found in 13 patients aged 44 to 69 years. In all studies we used a proton-weighted fat suppressed sequence (STIR) and serial T1-weighted gradient echo sequences before and after bolus injection of Gd-DTPA, MRI was correlated to ultrasound and in 8 cases to mammographic findings.

[MR-mammography assessment of tumor response after neoadjuvant radiochemotherapy of locally advanced breast carcinoma].

Purpose: We investigated the role of magnetic resonance mammography in monitoring tumour response of locally advanced breast cancer (LABC) after neoadjuvant radiochemotherapy.

Material And Methods: 17 patients with LABS had a magnetic resonance mammography and ultrasonography before and after neoadjuvant radiochemotherapy.

Results: After neoadjuvant radiochemotherapy 14 patients showed in MR-mammography less pronounced and prolonged enhancement without washout.

[Initial experiences with MR-mammography in after-care following surgical flap treatment of breast carcinoma].

Purpose: To demonstrate typical MR mammographic findings after plastic surgery of breast cancer.

Patients And Methods: Postoperative (7-38 months, median 13) MR mammographic examinations of 25 patients operated for breast cancer (11 latissimus dorsi-flaps (LAT), 14 rectus abdominis myocutaneous-flaps (TRAM)), were reevaluated. The examinations were performed with a breast coil at 1 T.
