13. Improved Identification of Noun Phrases in Clinical Radiology Reports Using a High-Performance Statistical Natural Language Parser Augmented with the UMLS Specialist Lexicon
Objective: The aim of this study was to develop and evaluate a method of extracting noun phrases with full phrase structures from a set of clinical radiology reports using natural language processing (NLP) and to investigate the effects of using the UMLS® Specialist Lexicon to improve noun phrase identification within clinical radiology documents.

16. A Pilot Study of Contextual UMLS Indexing to Improve the Precision of Concept-based Representation in XML-structured Clinical Radiology Reports
Objective: Despite the advantages of structured data entry, much of the patient record is still stored as unstructured or semistructured narrative text. The issue of representing clinical document content remains problematic. The authors' prior work using an automated UMLS document indexing system has been encouraging but has been affected by the generally l

17. Ad Hoc Classification of Radiology Reports
Objective: The task of ad hoc classification is to automatically place a large number of text documents into nonstandard categories that are determined by a user. The authors examine the use of statistical information retrieval techniques for ad hoc classification of dictated mammography reports.

19. A general natural-language text processor for clinical radiology.
OBJECTIVE: Development of a general natural-language processor that identifies clinical information in narrative reports and maps that information into a structured representation containing clinical terms. DESIGN: The natural-language processor provides three phases of processing, all of which are driven by different knowledge sources. The first phase perfo

21. The Canon Group's effort: working toward a merged model.
OBJECTIVE: To develop a representational schema for clinical data for use in exchanging data and applications, using a collaborative approach. DESIGN: Representational models for clinical radiology were independently developed manually by several Canon Group members who had diverse application interests, using sample reports. These models were merged into on

22. Audit of the histopathological diagnosis of non-neoplastic colorectal biopsies: achievable standards for the diagnosis of inflammatory bowel disease.
AIM: To assess the performance of a histopathology department in diagnosing inflammatory bowel diseases with comparison of reports from other centres. STUDY POPULATION: 1067 sets of endoscopic biopsies received in the department of histopathology, Royal Hallamshire Hospital, 1990-1995. METHODS: The histopathological diagnosis of non-neoplastic endoscopic col

23. Long-term follow-up after bilioenteric anastomosis for benign bile duct stricture.
OBJECTIVE: The authors provide a prospective evaluation of long-term results after bilioenteric anastomoses for benign biliary stricture. SUMMARY BACKGROUND DATA: With the advent of laparoscopic techniques, the frequency of bile duct injury after operation has increased. Reports on the operative management of these injuries have not provided long-term follow

24. Problem-oriented Prefetching for an Integrated Clinical Imaging Workstation
Prefetching methods have traditionally been used to restore archived images from picture archiving and communication systems to diagnostic imaging workstations prior to anticipated need, facilitating timely comparison of historical studies and patient management. The authors describe a problem-oriented prefetching scheme, detailing 1) a mechanism supporting
