MRI has identified five possible causes of patient complications from anterior cruciate ligament (ACL) reconstructive surgery, according to a study performed at Emory University Hospital in Atlanta, GA, and Sahlgrenska-Molndal University Hospital in Gothenborg, Sweden.

Diffusion weighted MR can accurately identify benign from malignant pelvic lymph nodes in patients with gynecologic malignancy, according to a study performed at Massachusetts General Hospital in Boston, MA. Diffusion weighted imaging is a noninvasive test that uses an MRI sequence sensitized to the motion of water molecules within tissue.

Manipulation of kVp (kilovoltage peak) and mAs (tube current flow) according to a patient's body shape may help reduce radiation doses in pediatric patients during CT, according to a study performed at the Cleveland Clinic Children's Hospital in Cleveland, OH.

A new automated system designed for the interpretation of coronary CT angiography (CCTA), helps radiologists determine which cases are high priority and should be read first, according to a study performed at Thomas Jefferson University in Philadelphia, PA.

Using cardiac CT to diagnose low risk patients with chest pain is significantly cheaper—44% less than the standard of care—and can decrease the length of hospital stay up to 20 hours, according to a study performed at the University of Washington in Seattle, WA.

Preoperative MR can help surgeons limit nerve damage while performing a robotic assisted laparascopic prostatectomy (RALP)—saving some men from becoming impotent, according to a study performed at the University of California, Los Angeles, CA.

The popular Wii gaming remote may offer radiologists a fun, alternative method to using a standard mouse and keyboard to navigate through patient images, according to a study performed at the New-York Presbyterian Hospital/Weill Cornell Medical Center in New York, NY. The remote may also offer radiologists relief from repetitive motion injuries as a result of using a mouse and keyboard.

A research team from Northeastern University and the National Institute of Standards and Technology (NIST) has discovered, serendipitously, that a residue of a process used to build arrays of titania nanotubes—a residue that wasn’t even noticed before this—plays an important role in improving the performance of the nanotubes in solar cells that produce hydrogen gas from water.

These days, chemical analysts are expected to track down even single molecules. To do this highly sensitive detective work, nano researchers have developed minute strings that resonate in characteristic fashion. If a molecule docks onto one of the strings, then it becomes heavier, and its oscillations become measurably slower. Until recently, however, such "nano-electromechanical systems", or NEMS, have been short of practical applications.

Copenhagen, Denmark, Thursday 23 April: The first identification of GP130 somatic activating mutations* in human tumours was announced today at EASL 2009, the Annual Meeting of the European Association for the Study of Liver Disease in Copenhagen, Denmark.
