Purpose The aim of this study was to estimate the cost effectiveness of breast cancer screening with contrast-enhanced magnetic resonance imaging (MRI), with and without adjunctive x-ray mammography (XM), compared with XM alone in high-risk women. Materials and Methods A model was developed to...
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...
87patients with histopathologically verified breast malignant lesions underwent dynamic contrast-enhanced MRI.The lesion detectability of T 1 WI,T 2 WI,and contrasted series,the signal intensity character,enhancement pattern,morphology manifestation of the lesions were observed.Results:There are different ...
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 ...
Preoperative contrast-enhanced (CE) breast magnetic resonance imaging (MRI) remains controversial in the newly diagnosed breast cancer patient. Additional lesions are frequently discovered in these patients with CE breast MRI. As staging and treatment planning evolve to include more information on tumor ...
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...
"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 ...
We compared the capability of PET-MR to that of same-day PET-CT to assess osseous metastases in patients with breast cancer. Methods: One hundred and nine patients with breast cancer, who underwent same-day contrast enhanced (CE)-PET-CT and CE-PET-MR, were evaluated. CE-PET-CT and CE...
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...
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...
