MRI for the size assessment of pure ductal carcinoma in situ (DCIS): a prospective study of 33 patients.

Objective: To determine whether MRI assesses the size of ductal carcinomas in situ (DCIS) more accurately than mammography, using the histopathological dimension of the surgical specimen as the reference measurement.

Materials And Methods: This single-center prospective study conducted from March 2007 to July 2008 at the Antoine-Lacassagne Cancer Treatment Center (Nice, France) included 33 patients with a histologically proven DCIS by needle biopsy, who all underwent clinical examination, mammography, and MRI interpreted by an experienced radiologist. All patients underwent surgery at our institution.

[Breast cancer screening imaging: what do we do].

The purpose of this review is to evaluate the value of different breast imaging technics and their place for individual and mass screening of breast cancer according to the randomized studies on digital mammography and ultrasound screening. Analogic and numerical mammograms are validated for screening of women aged from 50 and 74 years. The additional value of ultrasound is therefore proven when the increased risk is moderate.

[Anatomy of the female pelvis on MRI: value of intravaginal contrast].

Purpose: Prospective monocentric study to determine the feasibility, tolerability and diagnostic value of intravaginal contrast to assess female pelvic anatomy on MRI.

Materials And Methods: Forty-nine consecutive women referred for MRI evaluation of the pelvis, irrespective of the indication, were included in this study. The MR imaging protocol consisted of axial and sagittal T2W images before and after intravaginal instillation of sterile US gel.

[MR imaging evaluation of endometrial carcinoma].

Prognosis for endometrial carcinoma is closely related to cell type and tumor grade but also to local staging using the FIGO classification. MRI, under specific technical conditions, allows excellent depiction of the degree of myometrial tumor extension. It also has an excellent specificity for the detection of cervical extension.
