An imaging study of chronic users of codeine-containing cough syrups (CCS) has found deficits in specific regions of brain white matter and associates these changes with increased impulsivity in codeine-containing cough syrup users. These findings were consistent with results of previous studies of heroin and cocaine addicts. White matter disruptions also correlated with the duration of CCS use.

Scientists have developed an X-ray imaging system that enables researchers to see 'live' how effective treatments are for cystic fibrosis. Cystic fibrosis affects many of the body's systems, but most severely the lungs, and currently it can take several months to measure how effective treatment is for the early-fatal lung disease.

It’s a question that both cancer surgeons and patients ask after the removal of a malignant tumor – did the procedure “get” all of the cancer? Scientists have now engineered a hybrid imaging agent that maps out tumors before surgery, and causes cancer cells to glow during surgery – improving the surgeon’s ability to find and remove cancerous lesions while preserving healthy tissue.

The size of molecules penetrating the blood-brain barrier can be controlled using acoustic pressure -— the pressure of an ultrasound beam -— to let specific molecules through, a new technique has demonstrated for the first time. This innovative method may help improve drug delivery to the brain. Most small -- and all large -- molecule drugs do not currently penetrate the blood-brain barrier that sits between the vascular bed and the brain tissue. "As a result," one researcher explains, "all central nervous system diseases remain undertreated at best."

NIBIB-funded researchers have developed an imaging system that rapidly and accurately detects a molecular marker found in brain gliomas. It promises to improve the precision of these difficult surgeries by enabling the complete removal of the tumor, while reducing residual damage to brain tissue and neural function.

MRI technology has been melded with a traditional ultrasound prostate exam to create a three-dimensional map of the prostate that allows physicians to view growths that were previously undetectable. "With an ultrasound exam, we are typically unable to see the most suspicious areas of the prostate so we end up sampling different parts of the prostate that statistically speaking are more likely to have cancer," said one expert. "The MRI is a game-changer. It allows us to target the biopsy needles exactly where we think the cancer is located. It's more precise."

While in Germany a surgeon used a computer to perform a robot-assisted trans-Atlantic ultrasound examination on a person in Boston. In another study, a scientist showed how a cardiologist’s video e-consultation, coupled with a remote robot-assisted echocardiogram test, dramatically reduces the waiting time for a diagnosis faced by heart failure patients.

A rare metabolic disease that caused hundreds of seizures daily for a 6-year-old is now significantly under control as part of a clinical trial that uses a medicinal oil for treatment. Within hours, treatment with an edible oil dramatically reduced the number of seizures for then-4-year-old.

Wanting to replace the medical equipment for taking X-rays, experts in Mexico have created a system of digital x-ray imaging, which replaces the traditional plaque by a solid detector, which delivers results in five seconds. Analog equipment take six minutes to develop the traditional film.

A Canadian child is the first in North America to have undergone a specialized procedure that uses ultrasound and magnetic resonance imaging (MRI) to destroy a tumor in his leg without piercing the skin. Doctors used an MRI to guide high-intensity ultrasound waves to destroy a benign bone tumor called osteoid osteoma. The lesion had caused 16-year-old Jack Campanile excruciating pain for a year prior to the procedure. By the time he went to bed that night, the athletic teen experienced complete pain relief.
