For patients with residual or recurrent grade 2 isocitrate dehydrogenase (IDH)-mutant gliomas, magnetic resonance imaging (MRI) revealed that daily dosing of vorasidenib, an inhibitor of mutant IDH1 and IDH2 enzymes, led to a median progression-free survival of 27.7 months in comparison to 11.1 months in a placebo group, according to new research presented at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.
Can Alternative MRI Techniques Help Enhance CyberKnife Treatment Imaging?May 4th 2023
In a review of the literature, this author discusses the viability of artificial intelligence (AI), parallel imaging, compressed sensing and simultaneous multi-slice excitation for improving the scan times and use of magnetic resonance imaging (MRI) to facilitate CyberKnife treatment.
Study Shows Benefits of Reduced Energy Consumption with MRI Devices and Possible Millions in Cost SavingsApril 26th 2023
Researchers suggested that overnight use of a power-save mode on outpatient magnetic resonance imaging (MRI) devices in the United States could reduce annual energy consumption by 76,288.2 megawatt hours (MWh) and add up to $10.7 million in cost savings.
Could Controlled Imaging Rein in Suboptimal Use of MRI, CT and Ultrasound Exams?April 24th 2023
Lamenting a lack of control over imaging requests from referring clinicians, this author suggests that a more collaborative approach between referrers and radiologists may facilitate more efficient use of imaging.
Breast Reconstruction: Current Principles and Emerging Concepts in ImagingApril 17th 2023
Given the increasing prevalence of breast reconstruction, researchers discussed key signs of common complications on magnetic resonance imaging (MRI), ultrasound and other imaging during a recent presentation at the American Roentgen Ray Society (ARRS) 2023 Annual Meeting in Honolulu, Hawaii.
What a Breast MRI Study Reveals About Axillary Lymph Nodes and COVID-19 Booster VaccinationMarch 21st 2023
In a study of 128 patients who had breast magnetic resonance imaging (MRI) exams after COVID-19 booster vaccination, researchers noted that nearly 19 percent of the cohort had equal to or greater than 0.2 cm of increased lymph node cortical thickness.
Seven Key Considerations with Rectal Cancer MRIMarch 3rd 2023
In a cum laude awarded presentation at the European Congress of Radiology (ECR), researchers discussed misconceptions and pertinent principles for magnetic resonance imaging (MRI) of patients with rectal cancer, ranging from the diagnosis of mucinous tumors to the impact of mesorectal fascia status for rectal cancer recurrence.
Cancer Screenings and COVID-19: What a New Study ShowsFebruary 27th 2023
New research from the American Cancer Society comparing pre-pandemic cancer screening prevalence to the second year of the COVID-19 pandemic in the United States showed a 1.1 million decrease in breast cancer screenings, a 4.4 million decrease in cervical cancer screening and a 600,000 decrease in prostate cancer screenings.
Current Perspectives on the BCLC Staging System for Hepatocellular CarcinomaFebruary 24th 2023
Reviewing recent changes to the Barcelona Clinic Liver Cancer (BCLC) staging system for hepatocellular carcinoma and the potential impact for interventional radiologists, these authors discuss key updates including the subdivision of patients with intermediate stage disease and emerging literature on systemic agents for advanced disease.
Can Pre-Op Ultrafast MRI Predict Upgrade of DCIS Lesions to Invasive Breast Cancer?February 9th 2023
In a new study that may have implications for breast cancer surgery, researchers found that shorter time to enhancement (TTE) on preoperative ultrafast magnetic resonance imaging (MRI) was significantly associated with escalation of ductal carcinoma in situ (DCIS) to invasive breast cancer.
Interval Breast Cancer: What a New Mammography Study RevealsFebruary 6th 2023
In a new study of 1,232 women diagnosed with breast cancer within a year of a screening mammography exam, researchers found that interval breast cancer was 17 percent more likely in women with dense or extremely dense breasts, and over three times more likely to involve stage 2 or higher primary tumors in comparison to screening-detected breast cancer.
Can MRI Surveillance Have an Impact in Detecting Recurrence of Soft Tissue Sarcomas?February 3rd 2023
While acknowledging a moderate to high risk of bias in the retrospective studies reviewed for a recent meta-analysis, researchers found the current evidence supports the use of high-intensity magnetic resonance imaging (MRI) surveillance for detection of soft tissue sarcoma recurrence.
New Meta-Analysis Says MRI is Best Supplemental Imaging for Dense BreastsJanuary 31st 2023
In a review of 22 studies and data from over 132,000 women with dense breasts and negative mammography exams, researchers found that magnetic resonance imaging (MRI) was superior to digital breast tomosynthesis, handheld ultrasound and automated whole breast ultrasound for the detection of breast cancer.
Abbreviated MRI and Early-Stage Hepatocellular Carcinoma: What a New Multicenter Study RevealsJanuary 25th 2023
In a multicenter study involving nearly 300 patients, researchers found that abbreviated magnetic resonance imaging (MRI) had a sensitivity rate of 88.2 percent and a specificity rate of 89.1 percent for detecting early-stage hepatocellular carcinoma (HCC).
