Study confirms tamoxifen is superior to fulvestrant in blocking estrogen

For the first time, researchers at Seattle Cancer Care Alliance have demonstrated the feasibility of using serial positron emission tomography (PET) scans, using a special estrogen-containing isotope, to confirm the relative effectiveness of estrogen-blocking and estrogen-depleting therapy in patients with metastatic breast cancer.

Optical coherence tomography can distinguish between high and low risk pancreatic cysts

A team of researchers from four Boston-area institutions led by Nicusor Iftimia from Physical Sciences, Inc. has demonstrated for the first time that optical coherence tomography (OCT), a high resolution optical imaging technique that works by bouncing near-infrared laser light off biological tissue, can reliably distinguish between pancreatic cysts that are low-risk and high-risk for becoming malignant.

IMRT produces high response rate in patients with extranodal lymphoma of head and neck: Research

Lymphoma is a cancer that affects organs of the immune system, including the lymph nodes. In a subtype of the disease called extranodal lymphoma, tumors arise in non-lymphoid organs, such as the tongue and tonsils.

Role of molecular imaging in diagnosis and clinical trials

Two new studies published in the August issue of The Journal of Nuclear Medicine (JNM) provide insight into the potential of positron emission tomography (PET) to differentiate between types of dementia and to identify pharmaceuticals to slow the progress of dementia. With proposed National Institute on Aging (NIA) and the Alzheimer's Association guidelines for detecting Alzheimer's-related brain changes expected in September, these articles give a preview of what may be to come.

Mood-related brain protein linked to sadness during cigarette withdrawal

Heavy smokers may experience sadness after quitting because early withdrawal leads to an increase in the mood-related brain protein monoamine oxidase A (MAO-A), a new study by the Centre for Addiction and Mental Health (CAMH) has shown. This finding, which was published in the Archives of General Psychiatry, may also explain why heavy smokers are at high risk for clinical depression.

PSI develops new breast cancer diagnostic method

The Paul Scherrer Institute (PSI) has developed a new breast cancer diagnostic method, and is now carrying out first tests on non-preserved human tissue in conjunction with the Kantonsspital Baden AG. This new method should be able to reveal structures that cannot be seen using conventional mammography. Standard procedures only determine the extent to which X-rays are attenuated by various tissue structures.

New endoscopic OCT system enables 3-D imaging of esophagus, colon cancers

Researchers at the Massachusetts Institute of Technology (MIT) have developed a new imaging system that enables high-speed, three-dimensional (3-D) imaging of microscopic pre-cancerous changes in the esophagus or colon.

Methods for radiation dose optimization in head CT scans

An article in the August issue of the Journal of the American College of Radiology summarizes methods for radiation dose optimization in head computed tomography (CT) scans. Head CT is the second most commonly performed CT examination, with 28 percent of the total number of CT examinations.

Gundersen Lutheran staff develop comprehensive CT radiation dose reduction program

In an effort to reduce the radiation dose delivered by computed tomography (CT) scans, staff at a community-based hospital developed a comprehensive CT radiation dose reduction program which has allowed them to reduce the radiation dose delivered by CT scans at their facility, according to an article in the August issue of the Journal of the American College of Radiology.

Structural changes associated with frequent exacerbations identified in lungs of COPD patients

Using computed tomography (CT), researchers have identified two types of structural changes in the lungs of patients with chronic obstructive pulmonary disease (COPD) that are associated with frequent exacerbations, or episodes when symptoms suddenly worsen. Their findings are published online in the journal Radiology.
