MR, PET pick best biopsy sites for malignant gliomas
Clinicians can now choose from several MR and PET imaging strategies to identify a brain malignancy's most anaplastic area, according to German researchers.
Clinicians can now choose from several MR and PET imaging strategies to identify a brain malignancy's most anaplastic area, according to German researchers.
Dr. Marc-Andre Weber and colleagues from the German Cancer Research Center and nuclear medicine and radiology departments at the University of Heidelberg examined six approaches performed on 23 patients with gliomas. They found that the methods that single out areas of greatest microcirculation (dynamic contrast-enhanced MRI) and cell proliferation (MR spectroscopy or FLT-PET) are the ones best suited for marking the hot spot and enabling optimal grading of malignant gliomas.
The study was presented at the 2007 International Society for Magnetic Resonance in Medicine meeting.
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.
