Role of ultrasound-guided fine needle cytology of axillary lymph nodes in breast carcinoma staging.

Purpose: To evaluate the efficacy of cytology on axillary lymph node ultrasound-guided aspiration biopsy in the reduction of inappropriate surgery, such as the sentinel node (SN) procedure if positive, or axillary dissection if negative.

Materials And Methods: Cytology was performed on 159 consecutive cases, on the ultrasonographically most suspicious lymph node. Lymph node histology was used as a reference standard to determine accuracy.

Comparison of standard reading and computer aided diagnosis (CAD) on a proficiency test of screening mammography.

Purpose: To evaluate the role of computer aided diagnosis (CAD) to improve screening mammograms interpretation.

Materials And Methods: Six radiologists underwent a screening mammography proficiency test first by conventional, then by CAD assisted reading. Sensitivity and recall rate at conventional and CAD reading were compared.
