3-month PET/CT helps track oropharyngeal cancer
By Wayne Forrest
A three-month follow-up PET/CT scan is very helpful for detecting the recurrence of oropharyngeal cancer and predicting the overall survival of patients treated with radiation therapy, according to a study presented at the recent American Society for Radiation Oncology (ASTRO) Multidisciplinary Head and Neck Cancer Symposium in Scottsdale, AZ.

PET scans for lung and esophageal cancer may be overused
By Wayne Forrest
Multiple PET scans to evaluate post-treatment recurrence of lung and esophageal cancer do not improve two-year patient survival rates, which may mean the modality is overused, according to a study published online February 22 in the Journal of the National Cancer Institute.

Perfusion CT matters more than time to stroke treatment
By Eric Barnes
For ischemic stroke patients who are candidates for revascularization, CT perfusion imaging is more important for successful revascularization than the length of time from symptom onset, according to a study presented this week at the American Heart Association's International Stroke Conference.

Screening US spots thyroid cancer in healthy people
By Erik L. Ridley
CHICAGO - Screening ultrasound in asymptomatic healthy people can be useful for detecting early-stage thyroid cancer, and in South Korea at least, it can be done at a relatively low societal cost, according to research presented on Tuesday at RSNA 2015.

3D MRI uncovers risk of stroke in asymptomatic diabetics
By Wayne Forrest
3D MRI has found evidence of intraplaque hemorrhage among diabetics who have no signs of atherosclerotic disease -- a finding that could greatly increase their risk of an adverse vascular event, according to a study scheduled for presentation at RSNA 2015 in Chicago.

Ultrasound shows thyroid cancer spike after Fukushima
By Erik L. Ridley
Just as many had feared, the disaster at the Fukushima Daiichi nuclear power plant in March 2011 has sparked a sharp increase in thyroid cancer among children and adolescents in the area, according to a study published online in Epidemiology. And more cases may be lurking.

Low-risk cases fuel rising thyroid cancer rates
By Brian Casey
The rapid increase in the number of thyroid cancers diagnosed over the past decade is being driven by low-risk cases that would never pose a health threat to patients -- and one-third of these are asymptomatic cases being diagnosed with advanced medical imaging, according to a new study.

MRI finds brain changes in boys who faced adversity
By Wayne Forrest
MRI scans have found that boys who faced challenges during the first six years of their lives had less cortical gray brain matter and altered brain structure by the time they reached their late teens or early 20s, according to a study published online August 17 in JAMA Pediatrics.

Mobile stroke unit with CT improves survival, recovery
By AuntMinnie.com staff writers
Two new studies presented this week at the Society of NeuroInterventional Surgery meeting in San Francisco concluded that mobile stroke treatment units -- ambulances equipped with CT scanners -- can significantly reduce the time needed to diagnose and treat stroke patients, likely improving survival and boosting chances of recovery.

4D parathyroid CT sorts out lesion types
By Eric Barnes
CT scans with 4D image reconstruction can separate parathyroid adenomas and hyperplastic lesions into three distinct lesion types based on enhancement patterns, alerting surgeons to the variations they will find, according to a study in Radiology. The findings also indicate that a three-phase scanning protocol is still needed, the authors believe.
