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


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: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Tiny implants for cells are functional in vivo

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.

In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
