title: Value of the filter imprint technique in aspiration biopsy cytology.
abstract: In 468 fine needle aspiration (FNA) biopsies, after smearing of the aspirate on glass slides, additional material was obtained by flushing the needle with a fixative. The cells were collected on Millipore filters, from which imprints were prepared. The filter imprints were found to be sufficiently cellular in 60% of the cases, which reduced by 33 (7.3%) the number of cases with unsatisfactory aspirates. Diagnostic specificity and sensitivity were not influenced by the technique. The filter imprint technique was of particular value in breast aspirates.
