Ultra-high-field MRI developer Varian, Inc. announced that the University of California, San Diego has agreed to purchase four MRI systems in an order valued at approximately $9.5 million. UCSD made the order in cooperation with the Salk Institute for Biological Studies, Varian said.
UCSD has ordered 3-tesla and 4-tesla whole-body human imaging systems, a 4.7-tesla vertical-bore system for imaging upright primates, and a 7-tesla rodent imaging system. The four systems, set to be installed in October 2001 at the UCSD Center for Functional MRI, will allow UCSD and the Salk Institute to conduct wide-ranging research in neuroscience, cardiovascular mechanics, and advanced bioengineering, according to Palo Alto-based Varian.
The 3- and 4-tesla systems will form the backbone of the university’s functional MRI efforts, which include the studies of visual, cognitive, auditory, language, and developmental neuroscience.
The 4.7-tesla system will be used to map brain activity in primates for basic neuroscience and neuropathology applications, as well as cardiac, cardiovascular, and pulmonary imaging. The UCSD bioengineering department’s 7-tesla system will be used for cardiovascular studies in genetically altered strains of mice, according to Varian.

![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&fit=crop&h=112&q=70&w=112)
