Handheld DMR spectrometer diagnoses cancer in an hour

Magnetic resonance. We all think of the massive multimillion dollar magnetic resonance imaging machines into whose gaping mouth we are slowly propelled on a motorized table, ready to have our smallest flaws exposed. But the phenomenon of magnetic resonance has other medical uses. A team of physicians and scientists led by Prof. Ralph Weissleder of Massachusetts General Hospital (MGH) has developed a handheld diagnostic magnetic resonance (DMR) device that can diagnose cancer in an hour with greatly improved accuracy compared to the current gold standard. The DMR technique is sensitive enough that only material from a fine needle aspiration biopsy is needed for the test - a far less painful experience compared to the usual surgical or core needle biopsies.
