Medical experts support battle cry for PET scanners

They’re considered a vital tool in diagnosing cancer and deciding how to treat it.

But in Ontario, cancer patients don’t have access to PET scanners — imaging technology around for almost 30 years but still considered experimental in this province. “If I was a cancer patient, I would definitely scream for this technology that will let you know if you’re a candidate for surgery, whether to remove your tumour, whether you need surgery plus radiation or if you need chemotherapy,” said Dr. Jean-Luc Urbain, citywide chief of nuclear medicine in London.

Urbain is welcoming a call by Conservative health critic Elizabeth Witmer, who plans to introduce a resolution at Queen’s Park calling on the government to make PET scans available to Ontarians.

“PET scans are available to patients pretty well throughout the world — in Europe, Africa, the Middle East, the United States and other provinces in Canada,” Witmer said in a phone interview. “But here in Ontario, if your doctor recommends a PET scan, you are forced to travel to the United States at your own expense.”

Microsoft will extend life of Windows XP–again

MIAMI–As I predicted last week, Microsoft has decided to extend the life of Windows XP, although only for a limited class of machines.

Microsoft said on Thursday that it will continue to allow Windows XP Home edition to be sold for a class of computers it calls “ultra-low-cost PCs.” It’s a category that covers machines with slower processors, smaller screens, and in many cases flash memory for storage, rather than a traditional hard drive.

Microsoft will give PC makers the option of using Windows XP or Vista on ULCPC devices, said Michael Dix, general manager of Windows client marketing.

Still, the minimal hardware used in ULCPC systems might make Vista ill-suited to such a task. The decision to discontinue Windows XP might have driven even more device makers into the hands of Linux, hence the extension.

Overall, big-name computer makers are still scheduled to have to stop selling Windows XP for all other uses by the end of June. Mainstream technical support will continue to be available for Windows XP through April 2009, and more limited support will continue through April 2014.
