Experience of Ultrasonography-Guided Percutaneous Core Biopsy for Renal Masses

PURPOSE We evaluated the safety and accuracy of ultrasonography-guided percutaneous core biopsy collection in patients with renal masses. MATERIALS AND METHODS From June 2008 to August 2012, 30 percutaneous core biopsies of renal masses were performed. The biopsies obtained were small tumors (<4 cm) with ambiguous radiologic findings or that met classic renal biopsy indications. The biopsy re...

Ultrasonography guided fine needle aspiration biopsy of parotid gland masses.

OBJECTIVES The exact preoperative diagnosis of parotid gland masses requires highly specific and sensitive diagnostic techniques. The specificity, sensitivity and accuracy of ultrasonography guided fine needle aspiration biopsy of parotid gland masses were assessed. PATIENTS AND METHODS There were 46 female and 36 male patients. The mean age was 39 years (range 18 to 74 years). Ultrasonograph...

Ultrasonography-guided core-needle biopsy of parotid gland masses.

BACKGROUND AND PURPOSE An accurate diagnosis of a parotid gland mass is essential for adequate management. We determined the clinical efficacy of USCNB in diagnosing parotid gland masses by using cutting needles of different bores. METHODS We reviewed records for 40 benign and 13 malignant parotid lesions. USCNB was performed by using 14-20-gauge needles (mean, 16.6 gauge) with one to five (m...
