MR Spectroscopy Aids in Distinguishing Recurring Brain Tumors from Similar-Appearing Changes Related to Treatment


MR spectroscopy may be a useful adjunct to conventional imaging to distinguish recurrent tumor from treatment-related change in the brain such as inflammation or dead cells, says a new study by researchers from the University of Michigan Medical Center in Ann Arbor, MI.

In the study, MR spectroscopy was performed on 27 patients who were previously treated with surgery, chemotherapy and radiation therapy for brain tumor. Results of the study revealed that Choline, Creatine and N-acetylaspartate, specific molecules used as markers for identification of tumors and which can be detected with MR spectroscopy, were all readily quantifiable in each patient, allowing accurate recognition. “MR spectroscopy is a tool that can provide a biochemical thumbprint or profile of the brain, allowing accurate identification of recurrent tumor from benign changes related to chemotherapy or radiation therapy,” said Patrick N. Weybright, MD, lead author of the study.

According to Dr. Weybright, a down side to MR spectroscopy is that it is usually more susceptible to artifacts from nearby bone and fluid, which can make it impossible to identify the molecules. However, he said, by using techniques to suppress the overwhelming signal from water, they were able to achieve multivoxel spectroscopy in 25 of 27 patients with no significant artifacts.

According to the authors, the role MR spectroscopy can play in distinguishing recurrent tumor from tumor-related change is an important one for the patient. “It affects patient lifestyle. Early identification of recurrent tumor can allow earlier implementation of treatment to stop the tumor recurrence, and identification of benign changes related to treatment can prevent unnecessary therapy,” said Dr. Weybright.

Dr. Weybright will present the study on May 3 during the American Roentgen Ray Society Annual Meeting in Miami Beach, FL.

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

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: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions
