New Low-dose Cardiac CT technique At Porter Adventist …

Despite the significant importance of computed tomography (CT) scans, there are concerns regarding the delivery of high doses of radiation while performing CT scans. Currently, radiologists are looking for new solutions to improve the safety profile of CT.  For instance, physicians and technicians at Porter Adventist Hospital have recently designed a new low-dose cardiac CT technique. They also managed to create methods to reduce radiation exposure in other CT scans. Dr. Simeon Abramson, lead heart CT radiologist at Porter, said "As the technology became more advanced and highly useful in diagnosing people with disease at an earlier stage, we grew concerned over the amount of radiation exposure patients may face over their lifetimes," he added "We learned that it was possible to use software within our system that allowed us to reduce the radiation exposure in CT heart scans for most of our patients. The quality of the image has not been affected and we know that we are protecting our patients from potential harmful doses." Although CT scans are a very powerful and significantly important diagnostic tool, they still include delivering higher doses of radiation than other diagnostic imaging systems. A chest CT scan delivers radiation equal to that of 100 regular chest ... Read more

GE Reintroduces Its Optison Echocardiology Contrast …

GE Healthcare Medical Diagnostics announced that it has re-introduced its Optison, a contrast agent used with ultrasound for echocardiogram. It is a Perflutren Protein-Type A Microspheres Injectable Suspension, USP. Optison is indicated to be used with patients with sub-optimal echocardiograms in order to enhance the delineation of the left ventricular endocardial borders. However, the safety of Optison with pharmacologic or exercise stress is not established yet. Kimberly Wolf, Regional Marketing Leader - Americas, GE Healthcare Medical Diagnostics "We are excited to announce the reintroduction of Optison,” adding “The product gives medical professionals an option in ultrasound contrast agents when they need to increase diagnostic accuracy by converting non-diagnostic echo studies to diagnostic images.” Optison has an FDA approval in 1998. However, GE Healthcare stopped supplying it to the market in June 2009 as a result to difficulties in manufacturing. After reviewing production process, GE is now able to provide Optison again. Anthony N. DeMaria, MD, Professor of Medicine, Judith and Jack White Chair in Cardiology at the University of California, San Diego School of Medicine, said “Optison gives cardiologists, sonography professionals, cardiac catheterization laboratory nurses, echocardiography laboratory staff, and most importantly patients, an additional option in ultrasound contrast agent selection,” Data from the Intersocietal Commission for the Accreditation of Echocardiography Laboratories (ICAEL) say that nearly 10 million echocardiograms are carried out in the US annually. Moreover, about 30% of patients undergoing stress echocardiography have non-diagnostic or reduced-quality images. Therefore, echocardiographic contrast agents were developed to enhance the quality of images. Studies show that suboptimal echocardiograms could be changed into diagnostic images in 75% to 90% of cases. Steven B. Feinstein, MD, FACC, FESC, Professor of Medicine and Director of Echocardiography, Rush University Medical Center, Chicago, said “I am pleased that Optison is back on the market because it offers an important tool for improving the accuracy and reliability of echocardiograms, without unnecessarily exposing patients to ionizing radiation or dye,” he added “By improving the accuracy of echocardiograms, the use of ultrasound contrast agents also avoids redundant downstream ...

Radiology Assistants Have A New Role In Stroke Patients…

A new change was found to improve the role of radiology assistants, tried at the Norfolk and Norwich University Hospital (NNUH), in UK.  The new change means that radiology assistants are to help in preparing patients for radiology scans and look after them. The previous task was already carried out by radiographers. This new change provides radiographers with more time to focus on scanning patients. The new change resulted in quicker scanning with faster diagnosis and then the beginning of treatment of stroke patients within the crucial three-hour time limit. The initiative of the new change was started by radiographer Chris West, lead NNUH radiographer for CT scanning, and consultant stroke physician Dr. Kneale Metcalf, who said that the stroke services were designed and developed based on hyper-acute healthcare, which has allowed earlier CT scanning and thrombolysis for ischemic stroke patients. The unit is now carrying out twice as many scans within the first 24 hours, up from 40% to 80%. Dr. Metcalf said "In patients needing very urgent scans, within the first half an hour of coming through the door, we have put in place processes to do that and we are doing it robustly, 24 hours a day. Interacting with people on the ground within the CT scanning room allows us to arrange urgent scans; consequently, patient care is definitely better." The Radiology and Improving Stroke Services video forms part of the NHS Quality, Innovation, Productivity and Prevention (QIPP) program and is currently applied to assist other NHS hospitals for better understanding about enhancing the quality of such services. NNUH is providing services to a rural area of the UK, where faster access to CT scans is vital for patients suffering from strokes caused by a blood clot. This allows stroke doctors to detect and identify the type of stroke and then start using thrombolytic drugs during the critical period, significantly enhancing the chance of better recovery of the a patient. Dr. West also noted that radiology now has become a factor responsible for a major role in the treatment of stroke patients. He said ‘‘It sits centrally to the delivery of those services right from the point the paramedic identifies the patient and calls that case into hospital," he added "A stroke assessment nurse is waiting to assess the patient and then refer them straight to us. Previously this would have taken hours to achieve. Now, once the decision to image has been made, we can image them within 10 minutes. As allied health professionals we are in a really good position to influence the way patients are treated because we are right at the centre of a patient’s care pathway." Dr. West continued "we know what works well, and what doesn't," he added. "We can identify where the constraints are and then unlock them to deliver a better ... Read more
