MRI Virtual Biopsy of T2 Hyperintense Breast Lesions

Concordance Rate between Fine Needle Aspiration Biopsy and Core Needle Biopsy in Breast Lesions

Background and Objectives:Breast cancer is the most common cancer among women worldwide. Fine needle aspiration biopsy (FNAB) is one of the methods of breast biopsy which is fast, easy and cost effective. The aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided FNAB and guided core needle biopsy (CNB) in the evaluation of breast le...

T2*-weighted MRI technique for visualization of RF ablation lesions

Background LGE-MRI is widely used to assess cardiac RF ablation lesions. However, LGE-MRI requires contrast injection and the appearance, dimensions and visibility of lesions in LGE-MRI noticeably change with time after ablation and time after contrast injection. Recently proposed non-contrast T1-weighted (T1w) technique is only applicable to visualize acute (< 3 days) RF lesions. The main goal...

Preoperative localization and biopsy of exclusively MRI detectable breast lesions: Experiences with xx patients

METHODS: 118 exclusively MRI detectable breast lesions of 103 patients (age: 25 to 80 years, mean age: 50) were histologically proven by excisional biopsy after MRguided marking (n=89) or MR-guided microbiopsy (n=29). The interventional imaging was performed at 1 T (n=108) or 0.2 T (n=10). Lesion localization was carried out with an MR compatible metal coil (n=50) or a hook wire (n=39). Microbi...

Lesion characteristics, histopathologic results, and follow-up of breast lesions after MRI-guided biopsy.

PURPOSE We aimed to assess the effectiveness of magnetic resonance imaging (MRI)-guided vacuum-assisted breast biopsy (VABB), evaluate and compare the characteristics and histopathologic findings of lesions, and overview the follow-up results of benign lesions. METHODS MRI findings and histopathologic results of breast lesions biopsied by MRI-guided VABB between 2013 and 2016 were retrospecti...
