New image-processing software allows significant dose reduction A reduction by half in the radiation dose to which cardiac patients are exposed during diagnostic perfusion imaging is now "feasible", according to an Israeli study. Results from the study will be presented as a late-breaking trial at the International Conference of Non-Invasive Cardiovascular Imaging (ICNC) in Amsterdam (15-18 May). ICNC is now one of the world's major scientific events in nuclear cardiology and cardiac CT...

(Ivanhoe Newswire) -- Cardiac imaging tests, such as CT scans could be putting heart attack patients at a higher risk of cancer. According to a new study, exposure to low-dose radiation is associated with an increased risk of cancer. Typically, the amount of radiation that patients are exposed to is so small that it doesn't pose a major health risk, but when there are multiple scans the damage can start to add up. Patients with known or suspected coronary artery disease, tend to have more...

Exposure to low-dose radiation from cardiac imaging and other procedures after a heart attack is associated with an increased risk of cancer, found a new study published in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj100463.pdf. The use of procedures with low-dose ionizing radiation, such as computed tomography (CT) angiography and nuclear scans, is increasing which has led to mounting concern in the medical community that patients may be...

Multiple testing with the cardiac diagnostic imaging technique of myocardial perfusion imaging is common, and in many patients is associated with a high cumulative estimated radiation dose, according to a study in the November 17 issue of JAMA. The study is being released early online because it is being presented at the American Heart Association's annual meeting. Use of medical imaging has grown rapidly in recent years, but along with the potential benefits has come an increase in the...

Molecular imaging of severe heart disease can sometimes lead to false negative results, but doctors can better catch disease with computer analysis of blood flow to the heart A study revealed at SNM's 57th Annual Meeting urges physicians using molecular imaging for the diagnosis of heart disease to use computer data analysis rather than visual interpretation alone. The study shows that when combined, these techniques can improve early detection and diagnosis, especially in conditions that can...

Study finds that a molecular imaging agent combined with post-scan image processing technology could result in crisper pictures of the heart Molecular imaging of the heart just got better, according to a study revealed at SNM's 57th Annual Meeting. Combining a potential new imaging agent with a molecular imaging technique that reduces blur caused by the motion of the heart and lungs could lead to unprecedented image quality when conducting myocardial perfusion imaging, a procedure used to...

Recommendations could lower radiation exposure in 50% of myocardial perfusion imaging patients by 2014 BETHESDA, Md., June 1 /PRNewswire-USNewswire/ -- New recommendations published by the American Society of Nuclear Cardiology (www.asnc.org) could significantly lower radiation exposure for patients undergoing myocardial perfusion imaging (MPI) procedures. Focused on three areas -- patient selection, test selection, and technology adoption -- ASNC's information statement summarizes best...

Special issue of journal explores controversy, calls for more balance When patients present with chest pain or other high-risk symptoms of heart problems, doctors increasingly rely on nuclear imaging and computed tomography (CT) tests to find out whether there is evidence of heart disease, blockages in the coronary arteries or reduced blood flow to the heart. Results of these procedures can help guide life-saving prevention and treatment options. However, despite their widespread use and...

Radiation doses from common CT procedures vary widely and are higher than generally thought, raising concerns about increased risk for cancer, according to a new study led by UCSF imaging specialists. "In day-to-day clinical practice, we found significant variation in the radiation doses for the same type of computed tomography procedures within institutions and across institutions," said lead investigator Rebecca Smith-Bindman, MD, a professor of radiology at UCSF. "Our results highlight the...
