CTA improves, complicates management of PE
Researchers in Canada and the U.S. have found CT angiography to be as safe and accurate as ventilation/perfusion lung scans for ruling out pulmonary emboli. Results from what may be the first study of its kind suggest, however, that CTA could also spot many clinically irrelevant thrombi.
Researchers in Canada and the U.S. have found CT angiography to be as safe and accurate as ventilation/perfusion lung scans for ruling out pulmonary emboli. Results from what may be the first study of its kind suggest, however, that CTA could also spot many clinically irrelevant thrombi.
Dr. David R. Anderson and colleagues at one U.S. and four Canadian tertiary-care centers enrolled 1417 consecutive patients with suspected PE between May 2001 and April 2005. Patients were randomized to undergo either V/Q scanning (n = 716) or CTA (n = 701). Almost 20% of patients randomized to CTA were diagnosed with PE or deep vein thrombosis during the initial evaluation period, while 14.2% of patients in the V/Q scanning group had a similar diagnosis. Researchers cautioned that CTA could lead in many cases to unwarranted anticoagulant therapy. They published their findings in the Dec. 19 issue of the Journal of the American Medical Association.
Can Portable Dual-Energy X-Ray be a Viable Alternative to CT in the ICU?
September 13th 2024The use of a portable dual-energy X-ray detector in the ICU at one community hospital reportedly facilitated a 37.5 percent decrease in chest CT exams in comparison to the previous three months, according to research presented at the American Society of Emergency Radiology (ASER) meeting in Washington, D.C.
New Meta-Analysis Examines MRI Assessment for Treatment of Esophageal Cancer
September 12th 2024Diffusion-weighted MRI provided pooled sensitivity and specificity rates of 82 percent and 81 percent respectively for gauging patient response to concurrent chemoradiotherapy for esophageal cancer, according to new meta-analysis.
Study for Emerging PET/CT Agent Reveals ‘New Standard’ for Detecting Clear Cell Renal Cell Carcinoma
September 11th 2024Results from a multicenter phase 3 trial showed that the PET/CT imaging agent (89Zr)Zr-girentuximab had an 85.5 percent mean sensitivity rate for the diagnosis of clear cell renal cell carcinoma.
Can Radiomics and Autoencoders Enhance Real-Time Ultrasound Detection of Breast Cancer?
September 10th 2024Developed with breast ultrasound data from nearly 1,200 women, a model with mixed radiomic and autoencoder features had a 90 percent AUC for diagnosing breast cancer, according to new research.
