3D MRI Useful in Detecting Most Lethal of All Major Cancers

07.09.2005


3D MRI can detect pancreatic cancer when it is smaller and patients have a greater likelihood of survival, a new study shows.

The study included 57 patients who had clinical symptoms of pancreatic cancer. All had contrast enhanced 3D gradient-echo MRI examinations. Radiologists correctly identified pancreatic cancer in 24 patients, said Richard Semelka, MD, professor of radiology, at the University of North Carolina, Chapel Hill, and an author of the study. Eight of the cancers found were less than two centimeters in size, Dr. Semelka said. “Currently patients with pancreatic cancer are treated with complete surgical resection and the smaller the tumor, the easier it is to remove,” he said.

Pancreatic cancer is usually diagnosed too late, said Dr. Semelka. About 40,000 people are diagnosed with the disease in the U.S. each year, and nearly all of them die. Pancreatic cancer is the fourth most common cause of cancer death in the U.S. “The symptoms of the disease are somewhat nonspecific and can easily be misinterpreted. In addition, the disease is very aggressive so if the disease is missed or the diagnosis is delayed, the patient’s chance for survival is dismal,” he said.

3D MRI did indicate pancreatic cancer in three patients, but biopsy showed they did not have the disease. However, one did have a neuroendocrine tumor and one had focal pancreatitis. Three patients were lost to follow-up, said Dr. Semelka. “No patient with a study interpreted as normal was subsequently found to have pancreatic cancer,” he added.

“We are now working with our internists to detect this disease earlier,” said Dr. Semelka. “We are encouraging them to refer their patients for a 3D MRI examination if a patient has severe mid-abdominal pain not explained by a back problem, sudden development of diabetes and/or sudden development of jaundice. Radiologists who are reading 3D MR images of patients with abdominal pain should also look for pancreatic cancer even if the patient didn’t have the examination for that purpose,” he said.

The study appears in the September 2005 issue of the American Journal of Roentgenology.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
