Chemoradiotherapy May Benefit Recurrent Head, Neck Cancers
THURSDAY, June 16 (HealthDay News) -- Retreatment with concurrent chemotherapy and reirradiation (CReRT) may be a treatment option for a specific group of patients with recurrent or second primary head and neck cancer (HNC), although prior treatment with chemoradiotherapy (CRT) is associated with worse overall survival (OS), according to a study published online June 13 in Cancer.
Unequal Care Access for Children With Public Insurance
THURSDAY, June 16 (HealthDay News) -- Access to outpatient care is restricted for children with public insurance compared to those with private insurance, according to a study published in the June 16 issue of the New England Journal of Medicine.

New Device Performs PET, MRI Scans Simultaneously
FRIDAY, June 10 (HealthDay News) -- The first device to perform simultaneous position emission tomography and magnetic resonance imaging scans has been approved by the U.S. Food and Drug Administration, the agency said Friday.
New Diagnostic Strategy for Patients With Suspected PE
FRIDAY, June 10 (HealthDay News) -- A proposed diagnostic strategy combines clinical assessment, D-dimer testing, ultrasonography, and lung scan to give a noninvasive diagnosis for the majority of outpatients with suspected pulmonary embolism (PE), according to a study published in the June issue of Chest.
High-Pitch CT Offers Diagnostic Accuracy for Children
MONDAY, June 6 (HealthDay News) -- Use of high-pitch, dual-source computed tomography (CT) in pediatric patients with congenital heart disease offers diagnostic accuracy at lower radiation doses, according to a study published in the May 15 issue of The American Journal of Cardiology.
