Elastographic Evaluation of Indeterminate Breast Masses on Ultrasound.
Objective To evaluate the diagnostic accuracy of elastography for breast cancer identification in patients with indeterminate lesions on ultrasound. Methods This prospective, descriptive study included patients with indeterminate breast lesions in the ultrasound and with indication for percutaneous or surgical biopsy. The elastography was evaluated by qualitative analysis and by two methods for...
متن کاملEvaluation of a novel endobronchial ultrasound-guided lymph node forceps in enlarged mediastinal lymph nodes.
BACKGROUND Endobronchial ultrasound-transbronchial nee dle aspiration (EBUS-TBNA) is a useful technique for cytological assessment of enlarged mediastinal lymph nodes with a high diagnostic yield for lung cancer. However, the small sample volume can be problematic in diagnosing benign diseases and for molecular analysis of malignant tumours. OBJECTIVES The aim of the study was to evaluate a n...
متن کاملEndoscopic ultrasound-guided biopsies for mediastinal lesions and lymph node diagnosis and staging
OBJECTIVES To disseminate transesophageal ultrasound-guided fine needle aspiration (EUS-FNA) as an alternative to investigate mediastinal tumoral lesions because it is an underused modality that has been available in Brazil for more than 15 years. METHODS Descriptive analysis of a single endoscopy service's experience since 1997 in the accomplishment of EUSFNA for mediastinal staging of previ...
متن کاملIn Vivo Characterization of Pancreatic and Lymph Node Tissue using Endoscopic Ultrasound Spectrum Analysis: Validation Study
Background—Quantitative spectral analysis of the radio-frequency (RF) signals that underlie grayscale EUS images can be used to provide additional, objective information about tissue state. Objective—Our purpose was to validate RF spectral analysis as a method to distinguish between (1) benign and malignant lymph nodes and (2) normal pancreas (NP), chronic pancreatitis (CP) and pancreatic cance...
متن کاملThe Disappearance of Lymph Node Metastasis from Neuroendocrine Carcinoma after Endoscopic Ultrasound-guided Fine Needle Aspiration
A 75-year-old Japanese man was referred to our hospital to undergo the examination of an enlarged peripancreatic lymph node. Computed tomography (CT) showed a lymph node 47 mm in size that was located above the pancreas head and beneath the liver. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of the enlarged lymph node was performed, and an immunohistological examination of the ...
