’Healthy’ patients with abdominal lymph nodes seen on CT do not need follow-up imaging

10.01.2005


Smaller lymph nodes commonly seen on abdominal CT scans in "healthy" people are not clinically significant and require no further imaging, a new study confirms. The study was performed because there is no standard as to what should be done about these patients so they often undergo additional testing to rule out inflammation, cancer or other diseases.



Researchers examined CT scans of 120 patients treated in the emergency room following blunt abdominal trauma that had no history of an illness that may result in lymphadenopathy. Other than evidence of trauma, the patients were healthy and CT scans were normal, said Brian C. Lucey, assistant professor of radiology at Boston Medical Center, and lead author of the study. "We found that 39% of these patients (47 of the 120) had mesenteric lymph nodes (found in the area of the abdomen near the small intestines) averaging in size about 5 mm," Dr. Lucey said. "We examined hospital records a year after each of these patients had been examined, and there was no evidence that any of them had developed disease," he said. Dr. Lucey notes that there is the possibility that patients could have gone to other institutions for further medical care, however, "we feel it is reasonable to believe that this group of patients is representative of the healthy population."

"MDCT scanners and PACS computer workstations allow us to more clearly distinguish lymph nodes from vessels and other internal structures and that’s why we are seeing them more often," Dr. Lucey noted. "Multiple small nodes scattered throughout the abdomen are common, and follow-up imaging isn’t needed" he said. However, if there are large clusters of lymph nodes or the patient has a history of cancer, then follow-up imaging may be necessary, Dr. Lucey said.


The study appeared in the January 2005 issue of the American Journal of Roentgenology.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
