Ultrasound-guided percutaneous biopsies are a safe and effective alternative to endoscopic biopsies for obtaining samples in the pancreas, a new study shows.
The study included 23 pancreatic biopsies in 22 patients. “We were able to obtain adequate samples in 22 of the 23 cases,” said Kedar Chintapalli, MD, professor of radiology at the University of Texas Health Science Center in San Antonio and lead author of the study. The ultrasound-guided biopsies can be performed with small needles or a biopsy gun inserted through the skin after local anesthesia. In 16 of the procedures a 20G fine-needle aspiration (FNA) needle was used; seven cases were performed with an 18G biopsy gun. “Unlike with CT, one can compress the intervening tissues under ultrasound, so that the skin to target distance is less. The entire procedure is performed under real-time ultrasound,” said Dr. Chintapalli. A pathology resident or fellow was available when the FNA cases were peformed to confirm that the sample was adequate. “Adequate samples were obtained by FNA needle and the larger biopsy gun. If we can get an adequate sample we should use a smaller needle,” he said.
In most cases (61%) a diagnosis was possible after two passes with the biopsy needle. There were no major complications. In 14 of the patients, malignancy was diagnosed; eight patients had benign results.

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...
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...
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...
