New algorithm eliminates exposure to radiation when diagnosing children with acute appendicitis

Implementation of an algorithm aimed to diagnose pediatric patients with suspected appendicitis reduces the utilization of computed tomography (CT) scans, without affecting diagnostic accuracy, Mayo Clinic Children's Center researchers have found. The study was recently published in the journal Surgery.

UK researcher working to develop online tool to help patients navigate lung cancer screening decision

The phrase "we caught it early" is possibly the best news a patient can hear in the midst of a cancer diagnosis. Combating cancer in its earliest stages, when the disease is localized to a certain part of the body, gives patients the best chances of survival.

Prognostic value of visceral plural invasion limited in part-solid lung cancer

Visceral plural invasion is a significant predictor of survival in patients with small solid lung tumours but not in patients with part-solid tumours, Japanese study findings indicate.

Combined risk score enhances radiation pneumonitis prediction

Combining dose-volume histogram parameters with age and baseline pulmonary fibrosis score creates a novel predictive risk score that improves prediction of radiation pneumonitis in patients receiving concurrent chemoradiotherapy for non-small-cell lung cancer, research shows.

Study measures radiation exposure for children with heart disease

Complex heart imaging can increase cancer risks for children throughout their lifetime, according to a new study co-authored by Le Bonheur Cardiologist Jason Johnson, MD, MHS. The study, which appears in the June 9, 2014 issue of the American Heart Association's journal Circulation, is the first in which researchers quantified cumulative radiation doses in pediatric heart patients and predicted lifetime cancer risks based on the types of exposures.

Lung cancer screening with LDCT not associated with long term distress

Examination and review of several studies that evaluated patient-centered outcomes for individuals undergoing low-dose computed tomography (LDCT) screening for lung cancer found that screening does not appear to significantly influence overall health-related quality of life or result in long-term changes in anxiety or distress, but that positive results in the short-term, do increase distress levels.

Study show good compliance and patient survival outcomes using LDCT screening protocol

Investigators of the COSMOS (Continuous Observation of SMOking Subjects) study show good compliance and patient survival outcomes using a 5-year low-dose computed tomography (LDCT) screening protocol in individuals at high-risk of developing lung cancer.

New imaging software measures growth of nodules in patients at risk of lung cancer

Medical-imaging software under development at Rochester Institute of Technology could someday give radiologists a tool for measuring the growth of nodules in patients at risk of lung cancer, the leading cause of cancer deaths in the United States, according to the Center for Disease Control and Prevention.

REM sleep disorder: A sign of impending neurodegenerative disease

How many millions of people suffer from sleep disturbance? One sleep disorder in particular, called REM behavior disorder, could be a sign of impending neurodegenerative disease, including Parkinson's and dementia, say scientists presenting their research at the Society of Nuclear Medicine and Molecular Imaging's 2014 Annual Meeting.
