fMRI predicts benign brain tumors that turn malignant
Perfusion-weighted MRI can anticipate the transformation of low-grade gliomas into malignant tumors up to a year earlier than other imaging tests, according to researchers. The technique could help select patients who may benefit from more aggressive treatment.
Perfusion-weighted MRI can anticipate the transformation of low-grade gliomas into malignant tumors up to a year earlier than other imaging tests, according to researchers. The technique could help select patients who may benefit from more aggressive treatment.
Adam Waldman, Ph.D., and colleagues at the Charing Cross Hospital in London prospectively enrolled 13 patients with low-grade gliomas for two years ending in August 2002. Patients underwent perfusion- and contrast-enhanced MRI every six months for up to three years to check for tumor malignancy. Investigators found that increases in blood volume by perfusion MRI suggested malignancy a year or more before it could be observed by contrast MR. They published their findings in the April issue of Radiology.
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.
