This educational website was developed because a large majority of the estimated 590,000 radionuclide renal scans performed annually in the United States are conducted at sites that perform fewer than 3 studies per week.  Due to the relative infrequency of renal studies, some individuals may fail to acquire the expertise needed to provide a competent interpretation.   Limited training and experience may discourage the use of the procedure, lead to incorrect scan interpretation and negatively impact patient care.

The website is organized into a Home Page, an introduction page for Images and Parameters, a RENEX Introduction page, and a Case Review page. The Images and Parameters page contains a sample study with an explanation of relevant renogram parameters.  The RENEX Introduction page outlines the scoring system and provides a brief summary of RENEX [1-3].  The Case Review page contains ten Tc-99m MAG3 diuretic studies that may be reviewed in one or more settings and in any order.  The acquisition protocol consists of separate baseline and furosemide acquisitions, but the interpretative rational will usually be relevant for acquisition protocols that administer furosemide before or concurrently with Tc-99m MAG3.

NOTE:  The reader is referred to the SNMMI procedure standard/EANM guideline for a more complete description of diuretic renography [4].   As a reminder, the website needs to be viewed in Full Screen Mode for optimal function.
