A digital imaging system designed by Varian Medical Systems to improve the precision and effectiveness of cancer radiotherapy is operating at the Karolinska University Hospital in Stockholm, Sweden. The On-Board Imager allows physicians to precisely target tumors during image-guided radiation therapy. X-ray images of the patient's tumor obtained with the On-Board Imager are matched with CT scans to ensure that the tumor is aligned with the radiation beam according to the treatment plan. If it is not, the aim of the beam can be adjusted before treatment begins. The On-Board Imager is a standard feature on Varian's Trilogy linear accelerators and an option on its high-energy Clinac linear accelerators.
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.
