AJR: BI-RADS descriptors can predict malignancy for breast MRI lesions

نویسنده

  • Robert L. Gutierrez
چکیده

The researchers reviewed 1,523 consecutive breast MRI exams performed from Jan. 1, 2003, to June 30, 2005, to identify all lesions initially detected on MRI and assessed as BI-RADS 4 or 5 for which the patient underwent subsequent imaging-guided needle or excisional biopsy. They recorded BI-RADS lesion features for each case and the risk of malignancy was assessed using generalized estimating equations.

The positive predictive value of BI-RADS microcalcification descriptors and final assessment categories.

OBJECTIVE The purpose of this article is to retrospectively assess the likelihood of malignancy of microcalcifications according to the BI-RADS descriptors in a digital mammography environment. MATERIALS AND METHODS The study included 146 women with calcifications who underwent imaging-guided biopsy between April 2005 and July 2006. Digital mammograms procured before biopsy were analyzed inde...

Subdividing BI-RADS category 4 breast lesions observed on magnetic resonance imaging: Is it feasible?

Radiol Bras. 2016 Mai/Jun;49(3):V In clinical practice, there are various purposes for which magnetic resonance imaging (MRI) of the breasts is indicated, from the screening of high-risk patients to the staging and treatment planning for patients with breast cancer. This method has better sensitivity than conventional imaging (mammography and ultrasound) for the diagnosis of malignant breast le...

Nonpalpable BI-RADS 4 breast lesions: sonographic findings and pathology correlation.

PURPOSE We aimed to evaluate ultrasonography (US) findings for Breast Imaging Reporting and Data System (BI-RADS) category 4 lesions using BI-RADS US lexicon and determine the positive and negative predictive values (PPV and NPV) of US with respect to biopsy results. METHODS Sonograms of 186 BI-RADS 4 nonpalpable breast lesions with a known diagnosis were reviewed retrospectively. The morphol...

MRI for the assessment of malignancy in BI-RADS 4 mammographic microcalcifications

PURPOSE Assess the performance of breast MRI to diagnose breast cancer in BI-RADS 4 microcalcifications detected by mammography. MATERIALS AND METHODS This retrospective, IRB-approved study included 248 consecutive contrast-enhanced breast MRI (1.5T, protocol in accordance with EUSOBI recommendations) performed to further diagnose BI-RADS 4 microcalcifications detected at mammography during a...

We investigated the clinical impact of breast scintigraphy acquired with a breast specific γ-camera (BSGC) in the diagnosis of breast cancer (BC) and assessed its incremental value over mammography (Mx). A consecutive series of 467 patients underwent BSGC scintigraphy for different indications: suspicious lesions on physical examination and/or on US/MRI negative at Mx (BI-RADS 1 or 3), characte...
