Hybrid SPECT-CT greatly improves localization of gastrointestinal bleeding

08.05.2014

Prompt and accurate localization of the site of bleeding is critical for the management of patients with acute GI bleeding.

Planar 99mTc-labeled RBC scintigraphy is sensitive for detection of acute gastrointestinal (GI) bleeding but its accuracy for localization of a bleeding source is arguable, particularly in patients with complex GI anatomy from prior surgeries.

Researchers at the Cleveland Clinic reviewed cases of GI bleeding in patients who had a concurrent hybrid SPECT–CT for evaluating equivocal 99mTc-labeled RBC activity on planar scintigraphy.

Of those patients whose GI bleeding (as opposed to abdominal RBC activity due to other causes) was confirmed, SPECT–CT was 100 percent accurate in identifying the location of the bleeding.

"Judicious utilization of hybrid SPECT–CT for localization of the site of GI bleeding has the potential to improve clinical care by eliminating the ambiguities of planar scintigraphy," said researcher Ajit Goenka.

"Based on the performance of SPECT–CT in this study, we are [working] to make it a routine practice at our institution."

Dr. Goenka and his colleagues will present the study on May 8 at the 2014 ARRS Annual Meeting in San Diego, CA.

Founded in 1900, ARRS is the first and oldest radiology society in the United States and is an international forum for progress in radiology. The Society's mission is to improve health through a community committed to advancing knowledge and skills in radiology. ARRS achieves its mission through an annual scientific and educational meeting, publication of the American Journal of Roentgenology (AJR) and InPractice magazine, topical symposia and webinars, and print and online educational materials. ARRS is located in Leesburg, VA.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
