MRI spots patients prone to poststroke bleeds
Contrast-enhanced MRI reliably predicts whether acute stroke patients receiving intravenous tPA treatment are particularly susceptible to intracranial hemorrhage, according to a study presented at the American Society of Neuroradiology meeting in San Diego.
Contrast-enhanced MRI reliably predicts whether acute stroke patients receiving intravenous tPA treatment are particularly susceptible to intracranial hemorrhage, according to a study presented at the American Society of Neuroradiology meeting in San Diego.
Dr. David J. Mikulis, an associate professor of neuroradiology at Toronto Western Hospital, reported that the presence of blood-brain barrier breakdown identified with postgadolinium T1-weighted spin-echo imaging produced 100% positive and negative predictive values for 10 of 24 patients who developed hemorrhagic transformation.
Hyperintensities were absent in all 14 patients without intracranial bleeding but were seen in five of 10 patients who developed hemorrhage in the week following treatment.
Studies presented by Mikulis and other researchers at the meeting added weight to growing evidence demonstrating the power of MRI and CT to determine when tPA thrombolysis should be attempted beyond the traditional three-hour treatment window.
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.
