Could whole milk work just as well as the more expensive, barium-based contrast agents for imaging of the gastrointestinal tract?

In the next few months, researchers at the University of California at Los Angeles' (UCLA's) Jonsson Comprehensive Cancer Center will begin human studies on a new probe for Positron Emission Tomography (PET) that they believe will provide clinicians and researchers with a powerful new window on the immune system, as well as enable them to gauge early patient response to therapies.

The Food and Drug Administration (FDA) has sent an alert about X-rays used during CT examinations that might cause implanted and external electronic medical devices to malfunction.

Powerful new evidence has emerged demonstrating the benefits of radiotherapy in prostate cancer patients following radical prostatectomy.
-
It's great to be armed with scientific evidence, but it does no good if the patients who could benefit from this evidence are not referred to you for care.
-
It's unpleasant enough to receive a diagnosis of prostate cancer and to face a course of radiotherapy that can cause a number of side effects, ranging from incontinence to a loss of potency.

There is no question that the use of MRI prior to breast cancer surgery has increased dramatically in recent years. At the Mayo Clinic in Rochester, MN, for example, the use of preoperative MRI in breast cancer patients more than doubled between 2003 and 2006.
-
The idea of using milk as a contrast agent for gastrointestinal imaging has obvious appeal.
-
While radiotherapy is commonly prescribed following surgery for patients with node-positive head and neck cancers, until now there has been little evidence that it actually improves survival.
