Endoscopic ultrasound-guided liver biopsy using a 22-G fine needle biopsy needle: a prospective study

Endoscopy, 2019
Background Endoscopic ultrasound-guided liver biopsy (EUS-LB) using a 19-gauge (19-G) EUS needle is becoming increasingly popular. We evaluated the efficacy and safety of a 22-G EUS fine needle biopsy (FNB) needle for performing EUS-LB.

Percutaneous fine needle biopsy in pediatrics

Pediatric Radiology, 1985
We performed 25 percutaneous fine needle biopsies (PFNB) on pediatric patients during a 3-year period. Of 17 patients with proven malignancies, PFNB was true positive in 16 and false negative in one. In nine patients with benign or inflammatory disorders, there were three true positives and six false negatives.

Fine-needle biopsy of parathyroid adenomas

Klinische Wochenschrift, 1986
High-resolution real-time sonography was performed in 15 cases of clinically and chemically suspected primary hyperparathyroidism and in 20 patients with different thyroid nodules. The suspected enlarged parathyroid glands and the thyroid nodules were percutaneously punctured under sonographic control.

Fine Needle Aspiration Biopsy of the Liver

Advances in Anatomic Pathology, 1999
The liver is a commonly targeted deep-seated organ in which fine-needle aspiration biopsy (FNAB) is performed. By far, the most frequently encountered lesions on FNAB of the liver are metastases; however, a wide variety of other lesions have been described and are likely to be encountered.

Transvaginal Fine Needle Aspiration Biopsy

Acta Cytologica, 2001
To assess the role of transvaginal fine needle aspiration biopsy (FNAB) in the evaluation of palpable gynecologic masses.Transvaginal FNABs from 1994 to 1999 were identified from the files of Barnes-Jewish Hospital. Histologic correlation was obtained using the Pathology Department's computer database.

Inaccuracy of Fine Needle Aspiration Biopsy

Ophthalmology, 1985
Fine needle aspiration biopsy (FNAB) of orbital tumors has been recently advocated as a reliable diagnostic modality. An accuracy rate of 92% has been claimed by some authors. This figure remains unproven as most patients have not undergone simultaneous pathologic examination.

Orbital Fine-Needle Aspiration Biopsy

American Journal of Ophthalmology, 1985
Fine-needle aspiration was used as a primary orbital diagnostic technique in 156 patients. A 20-mm syringe, a 22-gauge, 3.75-cm needle, and a plastic pistol grip were used. Local anesthetic was not necessary. When the needle is in the lesion, small to-and-fro movements with a minimum of angulation are helpful.
