Diagnostic decision-making in pulmonary medical imaging has been improved by computer-aided diagnosis (CAD) systems, serving as second readers to detect suspicious nodules for diagnosis by a radiologist. Though increasing the accuracy, these CAD systems rarely offer useful descriptions of the suspected nodule or their decision criteria, mainly due to lack of nodule data. In this paper, we present a framework for mapping image features to radiologist-defined diagnostic criteria based on the newly available data). Using data mining, we found promising mappings to clinically relevant, human-interpretable nodule characteristics such as malignancy, margin, spiculation, subtlety, and texture. Bridging the semantic gap between computed image features and radiologist defined diagnostic criteria allows CAD systems to offer not only a second opinion but also decision-support criteria usable by radiologists. Presenting transparent decisions will improve the clinical acceptance of CAD.

Abstract In this paper, we address the system evaluation issue for commercial term extraction tools from the users’ perspective. We first revisit the gold standard approach commonly practised among researchers, and discuss the challenges it may pose on end users, taking translators as a typical example. Considering the very different motivations and needs of users and researchers, a user-driven approach is proposed as a variation and alternative to the gold standard approach to allow users to assess and understand the performance of commercial tools more objectively. Its feasibility and usefulness are demonstrated by deploying a benchmarking dataset of English-Chinese financial terms, produced by multiple annotators, in a case study with SDL MultiTerm Extract. The results also provide insight for future development of term extractors designed for translators, which will hopefully generate more accurate candidates, offer more customised features, enable better user experience, and enjoy wider popularity as a computer-aided translation tool.

Problems encountered in computing electrocardiographic diagnoses will be discussed. The method was to select voltage and time measurements for quantified diagnostic criteria. The selection was based on the physiologic events of the heart, the pathologic involvement for different diseases, the geometry of the lead system and the dispersion and overlap of the diagnostic groupings. It was possible to compute envelope surfaces which enclose each diagnostic grouping of persons. Specific measurements of voltages and times gave a great separation of persons with different diagnoses and little separation of persons with the same diagnoses.

Structurally-oriented biologists examine cells, tissues, organelles and macromolecules in order to gain insight into cellular and molecular physiology by relating structure to function. The understanding of these structures can be greatly enhanced by the use of techniques for the visualization and quantitative analysis of three-dimensional structure. Three projects from current research activities will be presented in order to illustrate both the present capabilities of computer aided techniques as well as their limitations and future possibilities.The first project concerns the three-dimensional reconstruction of the neuritic plaques found in the brains of patients with Alzheimer's disease. We have developed a software package “Synu” for investigation of 3D data sets which has been used in conjunction with laser confocal light microscopy to study the structure of the neuritic plaque. Tissue sections of autopsy samples from patients with Alzheimer's disease were double-labeled for tau, a cytoskeletal marker for abnormal neurites, and synaptophysin, a marker of presynaptic terminals.

Within the last few years, adrenal cortical tumors with features concordant with the diagnostic criteria attributed to oncocytomas have been reported. To date, only nine reported cases exist in the literature. This report is the tenth case presentation of a presumptively benign neoplasm of the adrenal gland with a rare differentiation. Oncocytomas are well recognized benign tumors of the thyroid, parathyroid, and salivary glands and of the kidney. Other organs also give rise to these types of tumors, however with less frequency than the former sites. The characteristics generally used to classify a tumor as an oncocytoma include the following criteria: the tumor is 1) usually a solitary circumscribed mass with no gross nor microscopic evidence of metastasis (no tissue nor vascular invasion), 2) fairly bland in terms of mitotic activity and nuclear morphology, and 3) composed of large eosinophillic cells in which the cytoplasm is packed full of mitochondria (Figure 1).
