Meme manyetik rezonans görüntüleme’de güncel yaklaşımlar

Öz

Meme Manyetik Rezonans Görüntüleme (MRG), meme radyolojisinde tarama, preoperatif evreleme, neoadjuvan kemoterapiye (NAKT) yanıtın değerlendirilmesi, primeri bilinmeyen kanser şüphesi ve implant değerlendirmesi gibi çeşitli endikasyonlarla kullanılmaktadır. Yüksek riskli hasta taramasında; aile öyküsü/genetik yatkınlık olanlarda mamografiye ek MRG, duyarlılığı ve özgüllüğü artırır. NAKT öncesi ek odakların saptanması ve işaretlenmesi multidisipliner yaklaşımı gerektirir. Preoperatif evrelemede ise başlıca ek odak, karşı memedeki bulgular, meme başı ve pektoral kas invazyonu varlığı gibi sorulara yanıt aranır.Yeni protokollerde ; Kısaltılmış MRG (AB-MRG) ve Ultrafast MRG, zaman ve maliyet avantajı sunar.BIRADS’ta MRG’de beklenen yenilikler arasında lenf nodu değerlendirmesi, foküs tanımı ve T2A sinyal yorumlarında değişiklikler olması gibi güncellemeler beklenmektedir.

Current Approaches in Breast Magnetic Resonance Imaging

Öz

Breast Magnetic Resonance Imaging (MRI) is used for various indications such as screening in breast radiology, preoperative staging, evaluation of response to neoadjuvant chemotherapy (NACT), suspicion of cancer of unknown primary origin and implant evaluation. In high risk patient screening; MRI in addition to mammography increases sensitivity and specificity in those with family history/genetic predisposition. Detection and marking of additional foci before NACT requires a multidisciplinary approach. In preoperative staging, answers are sought to questions such as additional focus, findings in the opposite breast, nipple and pectoral muscle invasion. In new protocols; Abbreviated MRI (AB-MRI) and Ultrafast MRI offer time and cost advantages. Among the innovations expected in MRI in BIRADS, changes are expected to be mainly in lymph node evaluation, focus definition and T2A signal interpretations.
