BACKGROUND The negative predictive value of endoscopic ultrasonography-guided fine needle aspiration for the diagnosis of solid pancreatic lesions remains low, and the biopsy specimens are sometimes inadequate for appropriate pathological diagnosis. AIMS To evaluate the usefulness of a novel method of contrast-enhanced harmonic endoscopic ultrasonography-guided fine-needle aspiration for the ...

This retrospective study was undertaken to evaluate the diagnostic usefulness of 244 sonographically guided fine- needle aspiration biopsy in 226 patients with ultrasonographically suspected hepatic malignant lesions. A final diagnosis of malignancy was established in 166 cases (73%) (145 hepatocellular carcinoma, 21 metastasis); benign lesions were aspirated in 60 cases (27%). The diagnostic s...

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.

Even though fine-root turnover is a highly studied topic, it is often poorly understood as a result of uncertainties inherent in its sampling, e.g., quantifying spatial and temporal variability. While many methods exist to quantify fine-root turnover, use of minirhizotrons has increased over the last two decades, making sensor errors another source of uncertainty. Currently, no standardized met...

INTRODUCTION Endoscopic biopsy techniques are useful in the diagnosis of sarcoidosis. There is a need for randomized trials to establish where these procedures fit in the diagnosis of sarcoidosis. OBJECTIVES The aim of the study was to compare the diagnostic yield of conventional transbronchial needle aspiration (TBNA) with endobronchial ultrasound-guided TBNA (EBUS-TBNA) and endoscopic ultra...

Background Context. Computed tomography- (CT-) guided fine-needle aspiration biopsy of the vertebral body is an important tool in the diagnostic evaluation of vertebral osteomyelitis. The procedure is considered simple to perform and it is considered a safe procedure with few complications. Purpose. The purpose of this study was to describe an unusual complication due to a CT-guided fine-needle...

OBJECTIVE Computed tomography-guided percutaneous fine needle aspiration biopsy of lung lesions is a simple, safe and reproducible procedure. Currently, it is widely used to diagnose lung lesions. However, different factors can influence the success rates of this procedure. The purpose of this study was to determine the influence of radiological and procedural characteristics in predicting the ...

Background & Objective: Modified Ultra-fast Papanicolaou (MUFP) stain has been developed from Papanicolaou stain (PAP) with the...
