Feature extraction is a crucial step in most cytometry studies. In this paper a systematic approach to feature extraction is presented. The feature sets that have been developed and used for quantitative cytology at the Laboratory for Biomedical Image Analysis of the GSF as well as at the Center for Image Analysis in Uppsala over the last 25 years are described and illustrated. The feature sets described are divided into morphometric, densitometric, textural and structural features. The latter group is used to describe the eu‐ and hetero‐chromatin in a way complementing the textural methods. The main goal of the paper is to bring attention to the need of a common and well defined description of features used in cyto‐ and histometrical studies. The application of the sets of features is shown in an overview of projects from different fields. Finally some rules of thumb for the design of studies in this field are proposed.

“…Digital databases are commonly used for the management of clinical data and the encyclopedic provision of visual information (for example, for a computer-based handbook and atlas of pathology [10], for computer-based data banks in dysmorphology [11], for construction of a diagnostic encyclopedia workstation [12] and for establishment of a multimedia database [13]). In addition, the Study Group for Complications of Perinatal Care (SGCPC) has developed a nondigital, perinatal autopsy protocol [14].…”

Objective: The aim of the current paper is to analyze the significant changes in fetal autopsy made by pathologists in a center for perinatal medicine in response to the recent rapid developments in prenatal medicine. Methods: We use our technical equipment (interdisciplinary databank, Intranet, fine instruments, imaging techniques) for prenatal diagnostics and fetal pathology in the Center for Perinatal Medicine at the Charité University Medical Center in Berlin, Germany. Results: Our technical setup has made it possible for us to plan autopsies in such a way that rare malformations in special cases can be documented in sectional planes corresponding to the prenatal sonographic images. Before the postmortem examination the pathologist receives all the prenatal findings obtained for the fetus and is able to examine the prenatal images on a monitor. The final diagnosis in the postmortem report includes the results of modern molecular pathology, clinical-genetic examination of the fetus, cytogenetic and molecular-cytogenetic findings and postmortem x-rays. Conclusions: To be able to incorporate these various results into a final report in routine work the use of an interdisciplinary database is essential. Such a database also ensures faster and more productive interdisciplinary communication in a center of perinatal medicine.

Modern ultrasonic diagnostic instruments with high resolution and color Doppler sonography allow the obstetrician to describe pathological findings very precisely and at an early stage of pregnancy. The use of high-resolution ultrasound makes it possible to detect heart malformations already between the 8th and 10th week of gestation. This development has essentially changed the clinical requirements on fetal autopsy which in its traditional way no longer meets the increased demands. Unless the pathologists faces this challenge the importance of fetal autopsy will diminish. Modern image databases and communication techniques allow the pathologist to have direct access to text and images of pre-findings by other clinics. Great importance, however, must be attached to the interdisciplinary cooperation with obstetricians and geneticists. We report on routine fetal autopsy by using an interdisciplinary database an the Charité.
