A general consensus on the role of testicular biopsy in non-obstructive azoospermia (NOA) is needed. This paper reviews and updates technical aspects and clinical performance of the percutaneous testicular biopsy techniques, in particular large-needle aspiration biopsy (LNAB), and proposes a flow chart for the management of NOA. The English literature and original data were reviewed or analyzed...

According to Scadding (1952) there are 83 causes of diffuse miliary or nodular shadows in the chest radiograph, some of which are manifestations of systemic diseases. It is hardly surprising that histological evidence is frequently necessary to make a definitive diagnosis. This may also apply to some localized lesions. Biopsy material is usually obtained by thoracotomy. However, even the modifi...

BACKGROUND Ultrasound guided transthoracic needle aspiration biopsy has recently been used to obtain specimens for histological diagnosis of pulmonary and mediastinal tumours. Conventional real time, grey scale puncture guiding devices cannot differentiate vascular structures, and clear visualisation of the needle shaft or tip within a desired target is not always possible. This study describes...

For evaluation of suspected infectious spondylitis, 19 consecutive patients underwent imaging-guided spine biopsy with needle aspiration and a percutaneous diskectomy device to determine if the diskectomy device provided diagnostic value. In 79% of cases, the diskectomy device yielded a specimen when needle aspiration failed. A significantly greater yield of specimen was observed with the diske...

BACKGROUND A number of reports of radiologically guided percutaneous biopsy of mediastinal masses have been described but techniques have varied, particularly the type of needle used. In this study mediastinal biopsies with fine aspiration needles and cutting needles have been compared, sometimes in the same patient. The results are reviewed with particular emphasis on the choice of biopsy need...

The present study compared the diagnostic yield of ultrasound-assisted cutting-needle biopsy (CNB) and fine-needle aspiration biopsy (FNAB) in chest lesions. A physician performed ultrasound and FNAB with a 22-G spinal needle in all patients, directly followed by a 14-G CNB in patients without contraindication. A total of 155 consecutive lesions arising from the lung (74%), pleura (12%), medias...

In childhood the traditional diagnostic approach to thyroid nodules consists of clinical, laboratory, and imaging evaluations. A safe and accurate procedure is needed to promptly identify patients who require surgery. In regard to the usefulness of fine needle aspiration biopsy, the data in the literature concerning children and adolescents are scanty. The aim of this study was to evaluate and ...

RM The primary goal of fine-needle aspiration is to acquire individual cells as opposed to tissue, which is the aim of fine-needle biopsy. Cells may not necessarily provide the stroma, or the associated architecture, of the surrounding tissue. Thus, if the surrounding architecture is needed to make a diagnosis, a fine-needle biopsy, which typically uses a core biopsy needle, should provide that.

PURPOSE The purpose of this study was to compare needle aspiration and vacuum-assistedbiopsy in the ultrasound-guided treatment of lactational breast abscesses. METHODS Between January 2005 and December 2014, a total of 74 patients presented withlactational breast abscesses. Thirty of these patients underwent treatment with antibioticsalone, while the remaining 44 lactating women with breast ...

Aim The aim of the study was to review two techniques that can be used to verify focal lesions in the breasts: fine-needle aspiration biopsy and core-needle biopsy. Material and methods Fifty-five articles (original papers and reviews), half of them published within the past 5 years, were included in the analysis. The authors also took their own experience into account. Results Pre-operativ...
