Big spectral CT project launches in New Zealand
By Eric Barnes
You've heard of dual-energy CT, but how about eight-energy CT? That's the goal of researchers in New Zealand, who this month received funding for a project to build a CT scanner capable of detecting eight different energies at once in scans of humans. They hope the new spectral scanner will offer functional imaging that is unprecedented for CT, with a lower radiation dose to boot.

Lung cancer patients do better when they quit smoking
By AuntMinnie.com staff writers
Patients with non-small cell lung cancer (NSCLC) who have quit smoking or never started in the first place have a lower risk of developing secondary primary lung cancers than NSCLC patients who keep smoking, according to a study presented at the just-completed American Society for Radiation Oncology meeting.

Ultrasound should be 1st choice for suspected kidney stones
By Erik L. Ridley
Ultrasound should still be the first imaging test of choice for evaluating patients with suspected nephrolithiasis, according to research published in this week's issue of the New England Journal of Medicine. The study found that using CT first didn't yield better clinical outcomes.

Perfusion CT's great potential remains unrealized
By Eric Barnes
Challenges remain on the road to more precise assessment of tumor treatment response with CT perfusion, but the techniques are already robust and far more sensitive than the old methods based on tumor size. In this emerging field, tumor biology and treatment response combine to make CT an ideal modality for monitoring cancer treatment, according to Boston researchers.

ICR: Survey reveals major knowledge gaps on radiation dose
By Philip Ward
DUBAI - The lack of knowledge among medical staff about radiation dose -- specifically for CT scans -- remains a serious concern, and patients still receive very little information about the pros and cons of scans, according to a survey presented at the International Congress of Radiology (ICR).

Mich. researchers hope to revamp lung CT image processing
By Eric Barnes
A new study at the University of Michigan aims to speed up image processing for low-dose CT lung cancer scans in the hopes of reducing reconstruction times to just a few minutes, which should result in lower radiation doses to patients.
