ARDMS examinations feature questions called Advanced Item Types (AIT). AIT questions assess a candidate in formats that closely relate to actual practice and, therefore, better measure practical sonography skills. The AITs allow the examinee to move closer to a hands-on testing environment.
ARDMS Semi-Interactive Console (SIC) questions feature a semi-interactive ultrasound machine console.
SIC questions display a partially completed ultrasound image and a question that indicates a problem with the image. Examinees will use a mouse to select the control on the simulated console that will correct the problem.
The ARDMS SIC questions use a proprietary format and cannot be reproduced here. However, the ARDMS has tutorials and sample questions on their website here.
Update: As of 2023, the ARDMS has removed current SIC items from the SPI examination while they redesign the format. While they may return in a new version, the exam currently consists of approximately 110 multiple-choice questions. However, There may be some "hot-spot" questions in which you are asked to indicate a region on an image with the cursor. Here's a link to a video on how to answer those types of questions.
