New research presented at the Society for Breast Imaging (SBI) conference suggests that abbreviated MRI is comparable to full MRI in assessing pathologic complete response to neoadjuvant chemotherapy for breast cancer.
Hybrid MRI Deep Learning Model Shows Promise in Predicting Tumor Deposits with Rectal Cancer
January 3rd 2024An emerging deep learning model, which incorporates T2-weighted MRI and clinical data, demonstrated an 83.9 percent AUC and an 85 percent specificity rate for preoperative prediction of tumor deposits in patients with rectal cancer.
Can ChatGPT and Bard Bolster Decision-Making for Cancer Screening in Radiology?
December 21st 2023In a study examining the potential of the large language models ChatGPT-4 and Bard to follow ACR Appropriateness Criteria for breast cancer, lung cancer, ovarian cancer and colorectal cancer screening, researchers noted “impressive accuracy in making radiologic clinical decisions.”
Is Contrast-Enhanced Mammography a Viable Option for Diagnosing Invasive Lobular Carcinoma?
December 15th 2023Contrast-enhanced mammography had a 98 percent sensitivity rate for diagnosing invasive lobular carcinoma and provided high conspicuity for 82 percent of detected lesions, according to research presented at the recent Radiological Society of North America (RSNA) conference.
Study Finds Questionable Adherence to Guidelines for Rectal MRI
December 15th 2023In one of the study periods from recently published research on rectal MRI acquisition, researchers found that 39.7 percent of rectal MRI exams adhered to guidelines from the Society of Abdominal Radiology (SAR) and only 6.8 percent followed guidelines from the European Society of Gastrointestinal and Abdominal Radiology (ESGAR).
Study: Black Patients Less Likely Than Others to Receive MRI Assessment of Cognitive Impairment
November 27th 2023In a four-year study of over 1,600 patients who had outpatient head CTs, head CT angiography and/or brain MRI to assess cognitive impairment, researchers found that Black patients were over 9 percent less likely than White patients and over 16 percent less likely than Hispanic patients to receive brain MRI.
Study Says Contrast-Enhanced Mammography Offers Comparable Breast Cancer Detection to MRI
November 15th 2023In findings from an enriched cohort of asymptomatic patients with screening-detected abnormalities, researchers found that contrast-enhanced mammography (CEM) was superior to conventional mammography and offered equivalent detection of breast cancer in comparison to breast MRI and abbreviated breast MRI.
Adjunctive Brain Volume Quantification Tool for MRI Gets FDA Clearance
November 14th 2023Providing automated brain volume calculations based on MRI images, NeuroShield’s artificial intelligence (AI)-powered technology may help facilitate treatment for neurodegenerative conditions ranging from Alzheimer’s disease to epilepsy.
Is Surveillance Imaging Necessary After Primary Radiation for Head and Neck Cancer?
November 13th 2023For patients who had a complete metabolic response to radiation treatment for head and neck cancer, the authors of a recent study found that surveillance imaging with PET/CT, MRI or CT did not improve outcomes in comparison to expectant management.
Study Says MRI Offers Most Cost-Effective Imaging for Dizziness Presentations in the ER
November 10th 2023Noting that initial imaging sensitivity is a key factor in cost-effectiveness for patients who do not require acute treatment for dizziness, researchers found that specialized MRI (including multiplanar high-resolution DWI) provided the most benefit in a comparative trial of neuroimaging modalities.
Study Links PTSD to Higher Carotid Atherosclerosis and White Matter Hyperintensity in Midlife Women
November 6th 2023Ultrasound and MRI findings from a new study suggest that greater carotid atherosclerosis and elevated white matter hyperintensities among women with the APOEe4 genotype, a strong risk factor for Alzheimer’s disease, are associated with increased PTSD symptoms in midlife women.
Meta-Analysis of 83 MRI Studies Suggests Link Between Adversity Exposure and Mental Health Issues
November 3rd 2023In their review of functional MRI data from over 5,200 study participants, researchers noted that higher amygdala reactivity and lower prefrontal cortical reactivity were associated with adversity exposure, findings that may contribute to exaggerated threat detection and reduced emotional control.
Current and Emerging Perspectives on Contrast Media in Radiology
November 1st 2023In a recent video interview series, Dushyant Sahani, M.D., discussed the critical role of contrast media in diagnostic imaging, lessons learned from the contrast media shortage, key considerations with generic agents and currently unmet needs with contrast agents.
Large MRI Study Links High Proton Density Fat Fraction to Elevated Liver Disease Risks
October 27th 2023In a study of over 375,000 people, researchers found that a high liver MRI proton density fat fraction was associated with an over 7.5-fold higher risk for non-alcoholic steatohepatitis, a 4.5-fold higher risk for malignancy, and a 3.8-fold elevated risk for cirrhosis of the liver.
