NSOCS Generates a Very Low Request Rate for Repeat Imaging

Objective: To evaluate the performance of the Neuroradiology Second Opinion Consultation Service (NSOCS) at the author's institution in terms of the number of requests for repeat imaging and the associated health-care cost. Design: Retrospective review of 11,753 NSOCS studies obtained during 2010. Methods: The database was queried separately with the keyword search function for the words "repeat" and "follow-up." The reports were reviewed and categorized based on study limitations into the following 5 groups: poor image quality (hard copy scanned images, low MRI field strength, and motion artifact); missing or inadequate standard MRI sequences and CT reformats or reconstruction algorithms; lack of IV contrast administration where otherwise deemed appropriate; an "other" category for miscellaneous items, including an incomplete FOV, inability to link multiplanar images or use of a measuring tool, inability to window, and poor reconstruction algorithm; and, a "clarification" category t more...
