Endorectal coil improves prostate cancer detection

23.11.2005


The image quality for detecting prostate cancer is significantly better for MRI at 1.5 T using an endorectal-body phased-array coil as compared with the 3.0 T imaging using the torso phased-array coil, a recent study found.



The study, consisting of 24 patients with prostate cancer, compared the use of MRI at 1.5 and 3.0 T in terms of image quality, tumor delineation, and depiction of staging criteria. MRI using an endorectal coil was found to be superior to the conventional body coil in staging prostate cancer, concluded the study.

"We did not expect to find such a clear and pronounced difference in overall image quality between the two techniques," commented Dirk Beyersdorff, MD, lead author and researcher.


Prostate cancer is the most common malignant tumor in men and the second most common cause of cancer death in men. Improving detection and identification of the cancer with MRI is a significant step in improving the techniques of managing the patient, said Dr. Beyersdorff. Correct preoperative staging is a prerequisite for choosing the optimal therapeutic strategy for the individual patient. "Preoperative staging should be performed using the best method available," said Dr. Beyersdorff.

The results of the study found that image quality and delineation of prostate cancer at 1.5 T with the use of an endorectal coil in a pelvic phased-array is superior to the higher field strength of 3.0 T with a torso phased-array coil. Both of these devices encircle the body at specific locations to create very detailed MR images. Currently, there are no endorectal coils refined for 3-T imaging.

"[The] results suggest that considerable advances in coil technology are necessary to improve prostate imaging at 3.0 T," said Dr. Beyersdorff. "It is expected that endorectal coils will become available for 3.0 T scanners in the near future, such a coil may be available early next year."

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
