According to a recent study, CT scans carried out to monitor lung cancer can be unreliable, leading to false results about the increase in the growth of cancer. The results of the study are discussed in the Journal of Clinical Oncology. Gregory Riely, from Memorial Sloan-Kettering Cancer Center in ...
 
Beta blockade combined with newer multi-detector CT angiography (MDCTA) reduced radiation exposure sevenfold compared to older scanners a new study shows. The new method may be the safest for coronary imaging for certain pediatric patients. In a retrospective study of all coronary CTAs performed on...
 
Growing scrutiny about the safety of CT scans has arisen in part out of widely publicized cases of excessive CT scanning, and of radiation over-exposure in CT scans, particularly CT perfusion scans for stroke, which have raised questions about CT dose index (CTDI) and CTDI volume measurements. On...

A new $1.2 million study is seeking to develop a new software, VirtualDose, for calculating and tracking a patient's radiation exposure from diagnostic X-rays & CT scans. The study is funded by the U.S. Institutes of Health (NIH) National Institute of Biomedical Imaging and Bioengineering (NIBIB) an...
 
According to a new study presented in the American Roentgen Ray Society Annual Meeting, using breast shields is the technique of choice to protect the breasts of women from radiation exposure during chest CT examination. The International Commission of Radiation Protection (ICRP) increased the ti...
 
Performing SPECT myocardial perfusion to image coronary arteries at half the usual radiation exposure yielded good or excellent images 95 percent of the time according to researchers in Israel. The study led by Dr. Nili Zafrir, of the Rabin Medical Center in Petah Tikva, Israel, used special imagin...
 
The American College of Radiology (ACR) has launched Dose Index Registry (DIR) as a component of its National Radiology Data Registry (NRDR). Medical imaging facilities are able to submit anonymized dose information for all CT exams performed to the DIR allowing them to compare their dose indices ...
 
CT imaging of the pelvis is unnecessary in patients undergoing CT imaging for a suspected pulmonary embolism and concomitant evaluation for venous thromboembolism a new study shows. The result could cut radiation exposure in people undergoing CT pulmonary angiography. The single institution study l...
 
According to a recent research being presented at the 2011 American Roentgen Ray Society's annual meeting, a 64-detector CT angiography utilizing prospective electrocardiographic (ECG) gating considerably reduces patient radiation dose when compared to retrospective ECG gating. The study was carr...
