Quality Assurance System Using Statistical Process Control: An Implementation for Image Cytometry
AIMS Optical technologies have shown some promise for improving the care of cervical neoplasia. We are currently evaluating fluorescence and reflectance spectroscopy and quantitative cyto-histopathology for cervical neoplasia screening and diagnosis. Here we describe the establishment and application of a quality assurance (QA) system for detecting system malfunctions and assessing the comparab...
متن کاملDNA Barcoding for Industrial Quality Assurance.
DNA barcoding methods originally developed for the identification of plant specimens have been applied to the authentication of herbal drug materials for industrial quality assurance. These methods are intended to be complementary to current morphological and chemical methods of identification. The adoption of these methods by industry will be accelerated by the introduction of DNA-based identi...
متن کاملPrognostic Impact of DNA-Image-Cytometry in Neuroendocrine (Carcinoid) Tumours
The report of Raatz, Böcking and Hauptmann [1] represents an excellent example of an in depth retrospective study on the influence of different clinico-pathological parameters including static DNA cytome-try on tumour prognosis illustrating the power but also some limitations of a comprehensive survival analysis in surgical pathology. The authors studied in total 44 neuroendocrine (car-cinoid) ...
متن کاملImage DNA cytometry in FNABs of Libyan breast disease.
BACKGROUND The sensitivity for identification of malignant cells in conventional fine-needle aspiration biopsy (FNAB) investigation is about 80%. This percentage is dependent on the number of examined cells, type of breast cancer, and experience of the examiner. The aim of our study was to estimate the supporting value of image DNA cytometry of FNAB of the breast, and do so by using different s...
متن کاملDiagnostic DNA-Flow- vs. -Image-Cytometry in Effusion Cytology
AIMS To determine the sensitivity and specificity of flow- and image-cytometry for the detection of DNA-aneuploidy as a marker for malignant cells in effusions. METHODS 200 effusions (80 tumor cell-positive, 74 negative and 46 cytologically equivocal) were stained with DAPI-SR for DNA-flow- and with Feulgen-Pararosaniline for -image-cytometry. They were measured using a PAS-flow-cytometer and...
