RESUMO
Recently we introduced a small Picture Archiving Communication System (PACS) for handling CT and MRI data. Our experience with this system has been useful in identifying potential problems in a clinical setting. Since the use of PACS raises both medical and social concerns, it cannot be instituted without addressing concerns related to the reliability and security issues. Although PACS is useful in the management of medical images, there are concerns about their reliability and security in a clinical setting. Reliability encompassed image quality, timeliness of the reports, and the PACS to the Radiological Information System (RIS) interface including the retrieval of the previously obtained images. The security of the patient's medical data is also essential.

Twenty-four conventional chest radiographs with small solitary pulmonary nodules were digitized to analyze optical density gradient. An index number, that could reflect sharpness and contrast of tumor lung interface, was calculated to differentiate benign from malignant pulmonary nodules. In four of 12 patients with benign non-calcified nodules, the index number allowed correct classification as a benign lesion.
