PET aids neuroblastoma management decisions
Children's hospitals in Cincinnati and Memphis, TN, have established the value of FDG-PET for depicting the extent of neuroblastoma in some patients, particularly for those in the early stages of the disease.
Children's hospitals in Cincinnati and Memphis, TN, have established the value of FDG-PET for depicting the extent of neuroblastoma in some patients, particularly for those in the early stages of the disease.
Lead author Dr. Susan E. Sharp, an assistant professor of clinical radiology at Cincinnati Children's Hospital Medical Center, and colleagues reviewed a total of 113 paired planar and SPECT Iodine-123I-metaiodobenzylguanidine (MIBG) and FDG-PET/CT scans in 60 patients with neuroblastoma. The investigators found that for stage 1 and stage 2 neuroblastoma patients, FDG-PET depicted more primary or residual neuroblastoma. However, they also found MIBG imaging may be needed to exclude higher stage disease that has spread to the bone or bone marrow (J Nucl Med 2009;50[8]:1237-1243).
Study Reaffirms Low Risk for csPCa with Biopsy Omission After Negative Prostate MRI
December 19th 2024In a new study involving nearly 600 biopsy-naïve men, researchers found that only 4 percent of those with negative prostate MRI had clinically significant prostate cancer after three years of active monitoring.
Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
