چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...

Computerized Interpretation of Dynamic Breast MRI

Magnetic resonance images are often corrupted byintensity inhomogeneity, which manifests itself as slow intensityvariations of the same tissue over the image domain. Suchshading artifacts must be corrected before doing computerizedanalysis such as intensity-based segmentation and quantitativeanalysis. In this paper, we present a fuzzy c-means (FCM)based algorithm that si...

breast cancer screening with mri

the sensitivity and specificity of mammography are limited in highly fibroglandular breasts (acr density c and d). digital mammography provides increased sensitivity in young women and those with moderately dense breasts, and digital three-dimensional mammography (tomosynthesis) promises further improvement. for women with the densest breasts, however, radiography is unlikely to be the optimum ...

Dynamic NMR effects in breast cancer dynamic-contrast-enhanced MRI.

The passage of a vascular-injected paramagnetic contrast reagent (CR) bolus through a region-of-interest affects tissue (1)H(2)O relaxation and thus MR image intensity. For longitudinal relaxation [R(1) identical with (T(1))(-1)], the CR must have transient molecular interactions with water. Because the CR and water molecules are never uniformly distributed in the histological-scale tissue comp...
