Ultrastructural analysis of fine needle aspirates from benign breast lesions.
Thirty six fine needle aspirates from various types of benign breast lesions were examined by electron microscopy and correlated with their cytological appearances. In all cases the parenchyma consisted of clumps of cohesive cells with the ultrastructural features of epithelial cells. In many cases, particularly from fibroadenomas, the parenchyma consisted of single layers of polarised epitheli...
متن کاملComputerized Diagnosis of Breast Fine-Needle Aspirates
The goal of this work is to determine the accuracy of computer-based image analysis in diagnosing breast fine-needle aspirates (FNA). On 192 FNAs, the computerbased diagnostic accuracy was 97.9%. This is consistent with the 97.5% accuracy projected by machine learning methods during the initial training in 1994 with 569 FNAs. One of the attributes of this system is the rendering of a value that...
متن کاملFlow cytometric DNA analysis of invasive carcinomas detected by screening mammography: use of specimen mammography-guided fine-needle aspirates.
Clinical studies of flow cytometric DNA analysis of breast carcinoma are often limited by the lack of fresh tissue samples from smaller, nonpalpable carcinomas. In addition, most studies measuring DNA in the current literature focus on larger palpable masses that may have less relevance to the smaller, nonpalpable lesions. A prospective study of flow cytometric DNA analysis of in vitro specimen...
متن کاملFlow cytometric immunophenotypic assessment of T-cell clonality by vβ repertoire analysis in fine-needle aspirates and cerebrospinal fluid.
Flow cytometric T-cell receptor V(β) repertoire analysis (TCR-V(β)-R) is a sensitive method to detect T-cell clonality; however, its implementation in low-cellularity specimens has not been established. We developed a strategy to use TCR-V(β)-R in cerebrospinal fluid (CSF) and fine-needle aspirate (FNA) specimens. Initially, full TCR-V(β)-R was evaluated in diagnostic/screening specimens from 8...
متن کاملQuantitation of plasma cells in bone marrow aspirates by flow cytometric analysis compared with morphologic assessment.
CONTEXT Accurate quantitation of bone marrow plasma cells is an important component in the diagnosis and posttreatment assessment of plasma cell dyscrasias. Although flow cytometry is sometimes used for this purpose and can rapidly evaluate many cells, the accuracy of flow-based plasma cell quantitation compared with morphologic assessment (currently the gold standard) is uncertain as direct co...
