16-MDCT shows promise in detecting coronary artery atherosclerosis

01.07.2004


16-MDCT is showing promise in detecting coronary artery atherosclerosis and could, in the near future, serve as an alternative to electron beam CT, a technique that is effective but not widely available, a new study shows.

The study of 100 patients at Hiroshima University in Japan found that 16-MDCT and electron beam CT were almost equivalent in detecting coronary artery calcifications and coronary artery calcium scoring. Calcium scoring is the "quantification of total calcium burden in the coronary artery," said Jun Horiguchi, MD, of the Hiroshima University School of Medicine. The score is expected to predict the patient’s risk for a heart attack, and can be used to track the progression or regression of coronary atherosclerosis, he said.

All patients in the study underwent both an electron beam CT examination and a 16-MDCT examination. 16-MDCT had a sensitivity of 98.7% and a specificity of 100%, Dr. Horiguchi said. The variability of calcium scores between the electron beam and MDCT scanners was comparable to earlier reports that had compared electron beam scanners to electron beam scanners, he added.



There are several advantages of 16-MDCT, said Dr. Horiguchi. It is more widely available; it provides thinner slice images and offers overlapping image reconstruction if needed, he said. In addition, patients do not have to hold their breath for as long during a 16-MDCT scan compared to an electron beam CT scan. A disadvantage of MDCT is there is relatively high radiation exposure to the patient, he said.

Electron beam CT is currently the gold standard for detecting and quantifying coronary artery calcifications, said Dr. Horiguchi. "However, we believe that 16 MDCT can be used for coronary artery calcium studies in the near future. Before that can happen, studies assessing interscan variability of 16-MDCT (MDCT scanners and MDCT scanners) must be done," he said. The study was published in the July issue of the American Journal of Roentgenology.

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.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
