FDG-PET/CT aids in assessing colorectal liver metastases October 3, 2012 -- FDG-PET's ability to assess metabolic tumors appears to be a valuable asset in determining the biology of colorectal liver metastases before surgical resection and may better evaluate patient prognosis, according to a study in the September issue of the Journal of Nuclear Medicine.
Real-time dose monitoring tool enhances VMAT radiotherapy QA October 3, 2012 -- Radiation oncology departments expect their linear accelerators to delivery radiation doses accurately as programmed. While it's possible to check planned dose delivery after treatment, safety for patients is increased if dose data can be monitored in real-time.
Fasting enhances response of glioma to radiation therapy October 3, 2012 -- Controlled fasting improves the effectiveness of chemotherapy and radiation therapy in mice with aggressive brain tumors, extending their survival, according to research published in September in PLOS One.
FFDM better for DCIS -- and it doesn't cause 'overdiagnosis' October 2, 2012 -- Full-field digital mammography (FFDM) performs better than film-screen mammography in detecting ductal carcinoma in situ (DCIS) and invasive cancer -- without increasing "overdiagnosis," a concern long highlighted by breast cancer screening critics, according to a new study in Radiology.
DWI-MRI helps reduce false-positive breast MRI scans October 2, 2012 -- Combining diffusion-weighted MRI (DWI-MRI) with dynamic contrast-enhanced MRI to calculate apparent diffusion coefficient values could decrease false-positive findings in breast MRI and reduce preventable biopsies, according to a new study published online on October 2 in Radiology.
AAA ultrasound screening hasn't saved many lives in Medicare October 2, 2012 -- Legislation that mandates ultrasound screening for abdominal aortic aneurysm (AAA) of individuals entering the Medicare program hasn't had much of a direct impact on mortality since taking effect in 2007, according to Stanford University researchers.
Dedicated breast MRI reins in false positives October 1, 2012 -- Use of a specialized breast MRI scanner led to a sharp decline in false positives compared to breast imaging on whole-body MRI scanners in a study published in the October issue of Radiology. The results address what has historically been a weak point for breast MRI: its specificity.
Noncontrast CT may underestimate lung nodule volume October 1, 2012 -- Low-dose unenhanced CT scans may underestimate the volume of smaller lung nodules compared with standard-dose contrast CT studies, creating potential problems when tracking nodules over time, wrote researchers in the October issue of the American Journal of Roentgenology.
Risk markers found for erectile dysfunction after RT October 1, 2012 -- Genetic markers associated with the development of erectile dysfunction in prostate cancer patients following radiation therapy (RT) have been identified, according to a study published online on September 27 in the International Journal of Radiation Oncology, Biology, Physics.
