Preoperative Localization of Breast MRI Lesions: MRI-guided Marker Placement With Radioactive Seed Localization as an Alternative to MRI-guided Wire Localization

Freehand MRI-guided preoperative needle localization of breast lesions after MRI-guided vacuum-assisted core needle biopsy without marker placement.

PURPOSE To evaluate the feasibility of magnetic resonance imaging (MRI)-guided preoperative needle localization (PNL) of breast lesions previously sampled by MRI-guided vacuum-assisted core needle biopsy (VACNB) without marker placement. MATERIALS AND METHODS We reviewed 15 women with 16 breast lesions undergoing MRI-guided VACNB without marker placement who subsequently underwent MRI-guided ...

Comparison of wire-guided localization and radio-guided occult lesionlocalization in preoperative localization of nonpalpable breast lesions.

BACKGROUND/AIM Breast lesions that are not palpable on physical examination but considered suspicious for malignancy on mammography or ultrasonography should be marked before surgery. Wire-guided localization (WGL) is the most frequently used method for preoperative marking of nonpalpable breast lesions (NPBLs). An alternative is marking by a radioactive agent (radio-guided occult lesion locali...

Assessment of Ultrasound / Radio-guided Occult Lesion Localization in Non-palpable Breast Lesions

Objective(s): Controversy exists about the localization of non-palpable breast lesions. In many countries, the gold standard for the diagnosis of these lesions is needle localization due to its accuracy. This study sought to compare the ultrasoundand radio-guided occult lesion localization (ROLL) as a simple method with the conventional procedures in terms of their diagnostic power. Methods: Th...

MRI-guided Needle Localization for Breast Lesions Occult in Mammograms and Ultrasound

To evaluate the diagnostic eff icacy of breast magnetic resonance imaging (MRI)-guided needle localization and surgical biopsy for suspicious breast lesions occult on physical breast examination, mammography and second-look ultrasound. Twelve patients (age range, 29-68 years; mean 44.9±9.24 years) received breast MR-guided needle localization and surgical biopsy for the suspicious lesions detec...
