Meme Kanserine Bağlı Beyin Metastazlarında Difüzyon Ağırlıklı Görüntüleme ile Histopatolojik Tip Arasında Bir İlişki Var mı?

Aim: The aim of this study is to evaluate the relationship between diffusion-weighted imaging (DWI) properties and apparent diffusion coefficient (ADC) values of metastases with the histological type of breast cancer in patients with breast cancer-related brain metastasis. Material and Methods: Between May 2008 - April 2011, 57 female patients who had been previously diagnosed with breast cancer in the radiology clinic were included in the study. Cases with invasive ductal carcinoma were considered group 1 (46 patients, 89 lesions) and cases with invasive lobular, comedo carcinoma and papillary cribriform carcinoma were considered group 2 ( 11 patients, 25 lesions). ADC values in both groups were compared by statistical analysis methods. Results: In group 1; 37 lesions (41.57%) and in group 2; 13 lesions (52%) included cystic component. In the group of invasive ductal carcinoma 48 lesions (53.92%) and 18 lesions (72%) of second group included peritumoral edema. The mean ADC value of the solid component of metastases (group1: 1.105x10-3mm2/ s, group2: 1.099x10-3mm2/ s) was higher than the average ADC value of normal brain parenchyma (group1: 0.790x10-3mm2/s, group2: 0.801x10-3mm2/s), and was statistically significant (p
