    Notes: Abstract. The aim of this study was to evaluate the accuracy of enteroclysis in the diagnosis of Crohn's disease of the small bowel in a group of consecutive patients. From January 1992 to December 1995, 165 patients with suspected Crohn's disease of the small bowel presented to our institution for enteroclysis. In 14 patients up to three enteroclysis exams were performed. Most patients (78 %) underwent colonoscopy and retrograde ileoscopy. In the remaining patients clinical follow-up was used as gold standard. In 79 patients no radiographic abnormalities were found. Sixty-one patients (40 men and 21 women; mean age 34.2 years) had a radiological diagnosis of Crohn's disease. This involved the terminal ileum in 39 patients (64 %) either alone (n = 25) or in association with the pelvic ileum (n = 14). In 12 of these patients retrograde ileoscopy was not feasible. Twenty-one patients underwent surgery. In 4 patients pathology revealed diseases other than Crohn's. These patients had all ileocecal diseases (tuberculosis = 2; non-Hodgkin's lymphoma = 1; adenocarcinoma = 1). One false-negative result was observed. Overall, enteroclysis showed a sensitivity of 98.2 % and a positive predictive value of 93.4 %. Enteroclysis is a sensitive technique in evaluating both the extent and the severity of small bowel involvement in Crohn's disease, although the overlap of radiographic findings may hamper its accuracy when the disease is confined to the ileocecal area.

    Description: loped by the Italian Consortium for Research on Advanced Remote Sensing Systems (CO.RI.S.T.A.). The system has been specially designed to satisfy archaeological requirements and it will be used to identify and characterise buried objects. The system is a stepped frequency GPR. It can work within a wide band of frequencies both in gated and ungated mode, and it has been already widely described in (Alberti et al., 2000). This paper describes the results of calibration tests in ungated mode performed in the CO.RI.S.T.A. laboratory. In particular, they show that the system can guarantee a dynamic range of about 96 dB.
