PET/MRI offers diagnostic accuracy for lymph node staging
By Wayne Forrest
Sunday, November 25 | 11:15 a.m.-11:25 a.m. | SSA12-04 | Room S504CDPET/MRI provides sufficient diagnostic accuracy for lymph node metastases detection, while diffusion-weighted MRI images are inaccurate for staging in head and neck cancer patients, according to researchers from the University of Düsseldorf.

Technologists are quick on the trigger to repeat head scans
By Eric Barnes
Wednesday, November 28 | 11:10 a.m.-11:20 a.m. | SSK16-04 | Room S403BIn a Canadian study, CT technologists rated head CT image quality lower than radiologists when artifacts were present, making them more prone to repeat scans and expose patients to additional radiation.

320-slice 4D head CTA derived from CTP replaces extra scan
By Eric Barnes
Wednesday, November 28 | 8:55 a.m.-9:05 a.m. | VSNR41-02 | Room E451BA new technique can boost the quality of low-dose head CT perfusion (CTP) to the point where it can replace higher-dose 3D CT angiography (CTA), say Dutch researchers, who will explain their findings in this scientific presentation.

CTA, arterial DSA most cost-effective modalities for intracranial aneurysm
By Eric Barnes
Tuesday, November 27 | 3:40 p.m.-3:50 p.m. | SSJ18-05 | Room N228CT angiography (CTA) and intra-arterial digital subtraction angiography (IA-DSA) are the most cost-effective modalities for patients presenting to the emergency department with suspected intracranial aneurysm, researchers from the Netherlands have found.

FLT-PET helps predicts cancer therapy results
By AuntMinnie.com staff writers
PET imaging with F-18 fluorothymidine (FLT) during treatment and early follow-up could predict therapeutic response and identify patients who need close follow-up to detect persistent or recurring head and neck squamous cell carcinomas, according to a study published in the October issue of the Journal of Nuclear Medicine.

CTA, not CTP, makes the call for ischemic stroke treatment
By Eric Barnes
Patient outcomes also depend on factors such as ischemic preconditioning and the presence of collateral vessels, so perfusion CT imaging is unlikely to add much to the therapeutic decision, Lev said. Future research will model multiple univariate imaging predictors, including collateral vessels.

CTA, not CTP, makes the call for ischemic stroke treatment
By Eric Barnes
CT perfusion (CTP) imaging of the brain brings multiple diagnostic benefits for ischemic stroke patients, but it's not needed when deciding whether to revascularize, according to neuroradiologist Dr. Michael Lev from Massachusetts General Hospital. CT angiography (CTA) can also be used as a surrogate for diffusion-weighted MRI to determine infarct size.

Meningioma patients report good QOL years after radiotherapy
By Cynthia E. Keen
A patient diagnosed with meningioma of the skull base can have several treatment options, all with known risks. Radiation therapy may be the more palatable option, maintaining or improving quality of life (QOL), according to a new study published in Radiotherapy and Oncology.

White children get more head CT scans for trauma
By AuntMinnie.com staff writers
The odds of undergoing head CT for minor blunt head trauma were higher for white children than for Hispanic or non-Hispanic blacks, but minority kids might actually be better off due to the disparity, according to a new data analysis in the August Archives of Pediatrics and Adolescent Medicine.

OCT found safe, feasible for imaging carotid arteries
By AuntMinnie.com staff writers
Optical coherence tomography (OCT) can reliably yield high-resolution images of the carotid arteries of vascular disease patients before, during, and after stenting procedures, according to a study in the June issue of the Journal of Endovascular Therapy.

PET/CT correctly alters esophageal cancer treatment
By AuntMinnie.com staff writers
Initial staging of esophageal cancer with PET/CT can help physicians determine whether curative or palliative treatment is the best management plan for patients, according to a study in the June issue of the Journal of Nuclear Medicine.
