Image Gently: Report and recommendations relating to pediatric cardiac CT
The Image Gently Alliance Have-A-Heart campaign has prepared a detailed report on radiation dose management and cardiac CT performance in children with congenital or acquired heart disease. The report in Pediatric Radiology offers expert opinions on radiation dose metrics and dose consideration, techniques to optimize the performance of cardiac CT, implementation of institutional CT dose monitoring, and communicating with parents.
Iterative reconstruction can improve image quality of abdominal CT of obese patients
Abdominopelvic CT is increasingly being used to image obese patients who have renal stone disease or undiagnosed abdominal pain. When iterative reconstruction (IR) image processing is used, high-quality images can be obtained without increasing radiation dose. Researchers from Massachusetts General Hospital in Boston confirmed this in a study comparing the diagnostic quality of reconstructed images of obese patients using either IR or filtered back projection published in Journal of Computer Assisted Tomography.
Shortening multiparametric prostate MRI protocols
The use of a single 3D T2-weighted image of the prostate could significantly shorten the duration of a multiparametric prostate MRI examinations according to a study published in European Radiology. Austrian researchers at the Medical University of Vienna determined that 3D T2-weighted image acquisitions showed equivalent image quality and lesion delineations compared with 2D T2-weighted image acquisitions.
Clinical implications of imaging findings following assisted reproduction
Complications associated with assisted reproduction can be life-threatening to a pregnant woman. A radiologist's awareness and prompt recognition of these can help safeguard the health of a mother and her fetus. Emergency Radiology has published a succinct review that describes imaging findings related to ovarian hyper stimulation syndrome (OHSS), to non-gynecological systemic complications caused by an altered blood coagulation profile, and to other pregnancy and post-delivery complications.
Serial lung US for assessment of pulmonary edema in ER
More than 1 million patients with symptoms of acute heart failure (AHF) are admitted to hospital emergency departments in the United States. A rapid, economic means of measuring pulmonary edema could help emergency physicians better plan a course of treatment and make better disposition decisions, especially for patients presenting with dyspnea, or shortness of breath. Serial lung sonography may provide this capability, according to a feasibility study conducted at the State University of New York Downstate Medical Center in Brooklyn. Changes in sonographic pulmonary decongestion can be semiquantitatively measured by a simplified serial 8-zone scanning protocol using a scoring method that accounts for ß-line fusion.
Late gadolinium MRI enhancement: a tool for risk stratification of patients with colorectal liver metastases?
Late gadolinium MRI enhancement of colorectal liver metastases is associated with tumor fibrosis and survival, Canadian researchers at Sunnybrook Health Sciences Centre at the University of Toronto report. Findings of a 10-year study published online in European Radiology suggest that target tumor enhancement on MRI may be a useful tool for risk stratification of these patients
