The study, which is being presented during the American Roentgen Ray Society Annual Meeting on May 3 in Chicago, found that radiologists using MRI could correctly identify the primary site of cancer in 79% of cases (38/48 patients) when biopsy results are inconclusive.
Endometrial and cervical cancers are common cancers in women, said Heather He, MD/PhD, of MD Anderson Cancer Center in Houston, where the study was conducted under the direction of Dr. Iyer and Dr. Bhosale. "In about 3% of the cases, there is difficulty determining the primary cancer site," she added. "Knowing the primary cancer site means that we can give the patients the most appropriate therapy and save some patients from unnecessary surgery," Dr. He said.
Two radiologists read the images as part of the study – one with five years experience and one with 18. Their diagnoses matched most of the time, which means that the readers' experience didn't have much of an impact on the study results, said Dr. He. "MRI can be applied on a broader scope; you don't have to have someone on staff with extensive experience to be able to offer this imaging service," she said.
The study also examined various MR sequences to determine which one was the most useful in making a diagnosis. "We found that sagittal T2 FSE weighted sequences and 2D and 3D T1 weighted dynamic enhanced sequences are the most helpful," Dr. He said.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
