Researchers identify 7 factors to lessen radiation exposure in young, traumatic injury victims

A study of more than 12,000 children from emergency departments throughout the country in the Pediatric Emergency Care Applied Research Network (PECARN) has identified seven factors that can help physicians determine the need for a computed tomography (CT) scan following blunt trauma to the abdomen.

Orbitofrontal cortex abnormality characteristic of deficit schizophrenia

The orbitofrontal cortex appears to play an important role in the development of severe negative symptoms in people with deficit schizophrenia, researchers suggest.

Degree of emphysema predicts mortality in ever-smokers with or without COPD

Severity of emphysema, as measured by computed tomography (CT), is a strong independent predictor of all-cause, cardiovascular, and respiratory mortality in ever-smokers with or without chronic obstructive pulmonary disease (COPD), according to a study from researchers in Norway. In patients with severe emphysema, airway wall thickness is also associated with mortality from respiratory causes.

Quarter of incident lung cancer slow growing or indolent

A quarter of incident lung cancers are slow growing or indolent, and may be overdiagnosed, suggest results from sequential low-dose computed tomography screening.

Study reports on development and testing of Hematuria Risk Index to predict cancer risk

Microscopic amounts of blood in urine have been considered a risk factor for urinary tract malignant tumors. However, only a small proportion of patients referred for investigation are subsequently found to have cancer. A new Kaiser Permanente Southern California study published in the February Mayo Clinic Proceedings reports on the development and testing of a Hematuria Risk Index to predict cancer risk.

Tibial artery calcification predicts foot ulceration

Tibial artery calcification is a significant risk factor for foot ulcers in patients with Type 2 diabetes, research suggests.

Study questions need for routine repeated CT scans in patients with mild head trauma

When initial computed tomography (CT) scans show bleeding within the brain after mild head injury, decisions about repeated CT scans should be based on the patient's neurological condition, according to a report in the January issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

18F-FDG PET/CT may become important distant staging modality in patients with breast cancer

New research published in the January issue of The Journal of Nuclear Medicine shows that 18F-fludeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) imaging offers significant prognostic stratification information at initial staging for patients with locally advanced breast cancer. When compared to conventional imaging, 18F-FDG PET/CT more accurately showed lesions in the chest, abdomen and bones in a single session, changing management for more than 50 percent of the patients in the study.

New analysis on global trends in medical imaging for cardiology applications

The promise of cost and clinical benefits are spurring the penetration of imaging modalities in cardiac applications. While demographics are favouring market growth, cardiac imaging device manufacturers will have to focus on innovative, patient-friendly products that promote greater safety and easier operability.
