Case report: Interventional retrieval of portacath fragment
March 10, 2014 -- Portacaths are commonly indicated for long-term administration of parenteral medications. This case report details the successful interventional retrieval of a fractured portacath fragment with cardiac migration. This is rather an unusual complication that, at times, can be life-threatening.
CT scanners show better agreement on risk than on CAC scores
March 9, 2014 -- VIENNA - State-of-the-art CT scanners produce widely divergent coronary artery calcium (CAC) scores, but at least they substantially agree on the risk levels of individuals undergoing the scans, according to a Saturday presentation at ECR 2014. However, even the risk agreement isn't strong enough.
Lower tube voltage reduces dose in stress CT perfusion MPI
February 25, 2014 -- Low-dose stress CT myocardial perfusion imaging of the heart is feasible at a tube current of 80 kV, producing image quality equivalent to 100 kV in a group of nonobese patients with a lower radiation dose, reported a team from Japan in European Radiology.
ESR holds out olive branch to European Society of Cardiology
February 12, 2014 -- Cardiologists and radiologists often stick to their own congresses, but this may change after the European Society of Radiology (ESR) has held out the hand of friendship to the European Society of Cardiology. Part two of our interview with ECR 2014 President Dr. Valentin Sinitsyn looks at this initiative.
Russian radiology prepares to step into limelight at ECR 2014
February 5, 2014 -- For the first time, there will be a Russian president of ECR next month: Dr. Valentin Sinitsyn, who is also one of the youngest presidents at 53. In the first part of our series of weekly articles looking ahead to ECR 2014, we discuss what this development means for radiology in Russia.
Italians develop novel strategy for CT-detected silent tumors
January 30, 2014 -- New research from Italy has highlighted how the use of CT is uncovering a growing number of incidental findings. About 4% of CT scans will detect a subclinical "silent" tumor in the adrenal gland, which presents a challenge due to inadequate information, according to the study authors.
Is point-of-care ultrasound the new stethoscope?
January 27, 2014 -- The role of point-of-care ultrasound in developing countries, the need for early ultrasound education, and the expansion of point-of-care cardiac ultrasound are among the featured topics in the latest issue of the World Heart Federation's Global Heart journal.
Coronary CTA identifies patients at risk of coronary syndrome
January 19, 2014 -- A negative coronary CT angiography (CTA) has a high predictive value for ruling out acute coronary syndrome and can decrease the hospital stay of patients who come to emergency rooms complaining of severe chest pain, according to a new study conducted in Saudi Arabia.
CMR ties MI scar length to ventricular tachycardia cycle
January 17, 2014 -- A study of patients with previous myocardial infraction (MI) undergoing late-gadolinium enhancement cardiac MR (LGE-CMR) found that scar length is strongly correlated to ventricular tachycardia cycle length, according to a study in Europace.
Charles Dotter's attack on arteriosclerotic obstructions
January 15, 2014 -- This week marks the 50th anniversary of Charles Dotter's first ever percutaneous transluminal angioplasty. The event transformed the practice of radiology, explains history columnist Dr. Adrian Thomas. He describes the first case and the global development of the procedure.
PET/MRI offers details in acute myocardial infarction cases
January 10, 2014 -- German researchers have concluded that simultaneous PET/MRI for patients with acute myocardial infarction is feasible after finding "good concordance" in a comparison of PET and MR images. The study was presented at last month's RSNA meeting in Chicago.
ESC issues stern warning on dose in cardiac imaging
January 9, 2014 -- The European Society of Cardiology (ESC) is urging cardiologists to take swift action to reduce radiation doses to patients wherever possible, according to a new position paper published on 8 January by the European Heart Journal.
Iterative reconstruction aids plaque assessment
January 7, 2014 -- Far from being a deterrent to evaluating plaque composition using CT, the use of iterative reconstruction has no effect on the visualization of plaque type, and improves image quality overall while reducing dose, according to Dutch research.
From quantum physics to clinical device
December 24, 2013 -- A research project that began as a comparative investigation into stationary and moving atomic clocks has led to the development of a new type of cardiac imaging device. A presenter at the U.K. Institute of Physics' Medical Physics Group's recent Translational Techniques meeting described how a collaborative effort bridged the gap between the lab and the clinic.
Calcium scores rise and fall based on scanner vendor
December 9, 2013 -- CHICAGO - What's your coronary calcium score? The answer may well depend on who made your CT scanner, according to a session at RSNA 2013. Dutch researchers who scanned cadaver hearts were surprised to see up to a 25% difference in scores, depending on which scanner was reporting the results.
