Multi-detector row computed tomography predicts malignancy of IPMNs

A clinical research article to be published on August 28, 2009 in the World Journal of Gastroenterology addresses the role of multi-detector row computed tomography (MDCT) in predicting malignancy of IPMNs preoperatively. The research team led by Prof. Wang DB from Ruijin Hospital of Shanghai Jiao Tong University School of Medicine recruited a total of 20 patients with pathologically-confirmed IPMNs in their study. Axial MDCT images combined with CT angiography (CTA) and multiplanar volume or curved reformations (MPVR or CR) were preoperatively acquired.

Comprehensive CT scan gives better indication of significant coronary artery disease

A team of researchers led by Massachusetts General Hospital (MGH) radiologists has developed a computed-tomography-based protocol that identifies both narrowing of coronary arteries and areas of myocardial ischemia - restricted blood flow to heart muscle tissue - giving a better indication of clinically significant coronary artery disease.

PET scanning made as publicly insured health service

Positron Corporation today announced that the Ministry of Health and Long Term Care of Ontario, Canada is making positron emission tomography (PET) scanning a publicly insured health service available to cancer and cardiac patients under conditions where PET scans have been proven to be clinically effective.

Carotid and cardiac procedures result in higher incidence of post-operative strokes

Among patients undergoing cardiac surgery, post-operative stroke occurred in approximately 2 percent, was not correlated with significant carotid artery narrowing, but was more common among patients who had combined cardiac and carotid procedures, according to a report in the September issue of Archives of Neurology, one of the JAMA/Archives journals.

NSF grants funds to develop next-generation nano-CT imaging system

In 1991, Ge Wang produced the first paper on spiral cone-beam computed tomography (CT), now an imaging technique used in the mainstream of the medical CT field. Today, Wang, known as a pioneer in this field, and his colleagues have been awarded more than $1.3 million from the National Science Foundation (NSF) to develop the next-generation nano-CT imaging system, which promises to greatly reduce the required dose of radiation.

BF STEM tomography allows to visualize fine details of cell structure

Scientists in the National Institute of Biomedical Imaging and Bioengineering (NIBIB) Laboratory of Bioengineering and Physical Science have developed a new technique that allows researchers to visualize fine details of cell structure three-dimensionally in thick sections, thus providing greater insight into how cells are organized and how they function. The work is described in a report published online this week in Nature Methods.

Gene causing periodontitis, rheumatoid arthritis and osteoporosis identified

Investigators at Hospital for Special Surgery, collaborating with researchers from other institutions, have contributed to the discovery that a gene called interferon regulator factor-8 (IRF-8) is involved in the development of diseases such as periodontitis (gum disease), rheumatoid arthritis and osteoporosis. The study, which will be published online August 30, ahead of print, in the journal Nature Medicine, could lead to new treatments in the future.

CT screening for coronary artery calcification can cause radiation-induced cancer

A study based on computer modeling of radiation risk suggests that widespread screening for the buildup of calcium in the arteries using computed tomography scans would lead to an estimated 42 additional radiation-induced cancer cases per 100,000 men and 62 cases per 100,000 women, according to a report in the July 13 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

New findings on molecular imaging and prostate cancer

A new study published in the September issue of The Journal of Nuclear Medicine shows that positron emission tomography (PET)/computer tomography (CT) scans with the imaging agent choline could detect recurring prostate cancer sooner than conventional imaging technologies in some patients who have had their prostates surgically removed.
