Study: Abbreviated MRI and DBT Offer Comparable Breast Cancer Detection in Dense Breasts
January 17th 2024For women with dense breasts, abbreviated breast MRI and digital breast tomosynthesis (DBT) both offered greater than 98 percent sensitivity rates and greater than 94 percent negative predictive values (NPVs) for breast cancer detection, according to newly published research.
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.

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.
