Multiple studies in the first decade of the 21st century have established contrast-enhanced breast MRI as a screening modality for women with a hereditary or familial increased risk for the developm...
MRI contrast medium uptake kinetics can help exclude the presence of invasion. However, the positive predictive value for the presence of invasion is limited. MRI features were more accurate at predicting invasion than mammographic features alone. 展开 关键词: Breast DCIS MRI Invasive ductal carcinoma...
Women with dense breasts often undergo conventional magnetic resonance imaging (MRI) despite its limited specificity, which may be increased by diffusion-weighted imaging (DWI) with apparent diffusion coefficient (ADC) and contrast. How these modalities are affected by breast density per se and their...
With regard to enhancement patterns, benign entities may demonstrate non-masslike regional or diffuse enhancement, homogeneous slow persistent enhancement, or no enhancement on MRI. However, that is not to say that benign tumors may not demonstrate rapid initial contrast enhancement. In fact, in our...
In the current era of breast imaging, magnetic resonance imaging (MRI) has an important role. To get its specificity better, some supporting or cooperative tools might be needed. The search for new methods continues and non-contrast MRI trials are seen. With the shorter and easier acquisition,...
Furthermore, our secondary endpoints were the predictive values of PET/CT, MRI, and combined PET/CT and MRI to predict ALN burden in five groups, including patients with 0, 1, 2, 1–2 (low burden), and 0–2 (indicator for SLNB) [7] positive ALNs on imaging. These predictive values...
An injection into a vein in the arm is frequently required for a breast MRI (contrast MRI). MRI breast is the best screening test for breast cancer in women. 9 indications of MRI breast Women with a high risk of breast cancer, who have a family history of breast, ovarian, or fallopian...
Physical examination revealed a well-demarcated firm tumor with good mobility. Mammography and ultrasonography revealed a well-circumscribed tumor of 30 × 20 × 25 mm, and magnetic resonance imaging (MRI) showed rich vascularity, especially in the periphery. Fine-needle aspiration and core needle ...
"By comparing the level of contrast enhancement in the same women with and without the IUD in place, a change in systemic hormone levels due to the IUD could be traced," Dr. Huck said. Left image shows 45-year-old patient with IUD in place. Right image shows breast MRI of the same ...
