Optimizing electronic presentations.

RATIONALE AND OBJECTIVES: Radiologists often use electronic presentations for educational and research purposes. Many physician educators may not know how to best utilize this technology. MATERIALS AND METHODS: A literature search was performed to find information regarding optimal use of electronic presentations. RESULTS AND CONCLUSION: Information from a variety of sources was compiled to provide a guideline for creating electronic presentations.

Automated storage and retrieval of thin-section CT images to assist diagnosis: system description and preliminary assessment.

A software system and database for computer-aided diagnosis with thin-section computed tomographic (CT) images of the chest was designed and implemented. When presented with an unknown query image, the system uses pattern recognition to retrieve visually similar images with known diagnoses from the database. A preliminary validation trial was conducted with 11 volunteers who were asked to select the best diagnosis for a series of test images, with and without software assistance. The percentage of correct answers increased from 29% to 62% with computer assistance. This finding suggests that this system may be useful for computer-assisted diagnosis.

PET scan-CT correlation: what the chest radiologist needs to know.

The purpose of this article is to familiarize the chest radiologist with the basics of PET scanning in the chest and to correlate PET findings with thoracic CT findings. After completing this article, the reader should know the following: (a) how PET scanning is performed; (b) the indications for PET scanning in the chest; (c) the significance of SUV and a positive test; (c) the causes of false-positive and false-negative PET scans; and (d) the importance of correlating PET findings with Chest CT findings. The authors conclude that PET and chest CT studies should be read in conjunction to optimize diagnostic accuracy. Interpreting either study alone is fraught with errors, while combined interpretations yield information on both functional activity and anatomic localization. PET-CT hybrid devices that fuse PET and CT data simplify this task and fusion imaging is rapidly becoming the test of choice for evaluating thoracic malignancies.

Image-guided coaxial fine needle aspiration biopsy with a side-exiting guide.

PURPOSE: The aim of this study was to evaluate the diagnostic accuracy and complication rates of a side-exiting coaxial needle system for fine needle aspiration (FNA) biopsies. METHOD: Between 1995 and 1998, 127 nonconsecutive biopsies were performed on 122 patients (74 males, 48 females). CT guidance was used in 111, ultrasound guidance was used in 14, and both were used in 2 biopsies. Patient history, biopsy site, needle performance, complications, and cytology results were recorded. RESULTS: Diagnostic rate and accuracy were 92.9 and 99.2%, respectively. There were minor complications from 14 biopsies, and all of them arose from chest biopsies: pneumothorax in 13 of 47 and hemoptysis in 1 of 47. There were no major complications. CONCLUSION: The side-exiting coaxial needle system is a safe and effective alternative to the conventional end-exiting coaxial needle system for performance of image-guided FNA biopsies.
