Ultrasound-guided core-needle biopsy of breast lesions.

OBJECTIVE: To review the role of ultrasound-guided core-needle biopsy (CNB) in the management of breast lesions. METHODS: Review of the most relevant literature on this topic. RESULTS: This technique shows a high sensitivity value of about 97.

[Radiofrequency ablation of breast carcinomas: preliminary results of a clinical trial].

Objective: Among the alternatives to breast conserving surgery in breast cancer, radiofrequency ablation is the most widespread. We aimed to determine the feasibility, safety, and efficacy of this technique in our environment.

Material And Methods: We performed radiofrequency ablation of breast carcinomas under local anesthesia in the ultrasonography examination room.

[Adenoid cystic carcinoma of the breast].

Objective: To review the clinical presentation and imaging findings of adenoid cystic carcinoma (ACC).

Material And Methods: We performed a retrospective study of the period between January 1990 and July 2004, comprising five cases of ACC of the breast, all in women, among 4,036 malignant lesions diagnosed (0.12%).

[Radiological control following breast reconstructive surgery].

Introduction: Radiological control of the breast that has been operated because of cancer and reconstructed has a double aim: to provide early detection of any recurrence and data on the state of the reconstructive mechanisms employed.

Methods: We must know the clinical-surgical antecedents of the patient, especially the surgical technique, the implant model used, its localisation and the existence of any symptomatology. The radiological techniques employed are the mammography, ultrasound and magnetic resonance.

[Biopsy techniques for the diagnosis of non-palpable mammary lesions].

Facing a non-palpable mammary lesion requiring a diagnostic biopsy, consideration must be given to the most suitable guiding method for obtaining the latter. Three methods are employed at present: stereotaxy (basically in cases of microcalcifications), echography (above all in the nodules), and magnetic resonance (for lesions not made visible through the previous systems). The next step is to select the most suitable biopsy technique.
