MRI Technique for Measuring Blood Volume Helps Distinguish Between Abscesses and Tumors in the Brain

09.11.2004


Dynamic susceptibility contrast (DSC) MRI allows physicians to differentiate between cerebral abscesses—inflamed areas in the brain caused by infection—and malignant brain tumors without surgery, says a new preliminary study by researchers from Duke University Medical Center in Durham, NC.



For the study, the researchers analyzed eight patients who underwent DSC MRI—four with cerebral abscesses and four with malignant brain tumors. DSC MRI is used to measure blood volume in brain tumors. Malignant brain tumors have high blood volume because they need new blood vessels in order to grow, while abscesses have the same blood volume as healthy tissue. On analyzing maps produced by DSC MRI of cerebral blood volume in these eight patients, the researchers found no overlap in the blood volume between the group of abscesses and the group of tumors .

According to the researchers, DSC MRI and traditional MRI are fundamentally different in the types of information they provide. “Regular MRI scans show the size and shape of a muscle or organ very well, but they don’t tell us much about how it is functioning. As we get more sophisticated in imaging organs, we want to know more than simply their size and the shape. DSC MRI gives us that additional necessary information, letting us know the vascular needs of the tissue ,” said James M. Provenzale, MD, one of the authors of the study.


Distinguishing between abscesses and tumors is a frequent problem for radiologists. “The distinction between abscess and tumor can be made by surgically removing tissue from the brain, but one would rather make the diagnosis by a noninvasive measure. The treatments for the two entities are also different: antibiotics for abscesses and surgical removal, chemotherapy or radiation therapy for tumors. A worst-case scenario would be one in which the wrong treatment is given for weeks or months due to a misdiagnosis,” said Dr. Provenzale.

The article appears in the November 2004 issue of the American Journal of Roentgenology.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
