Obesity impairs accuracy of obstetric sonography
Pregnant women who are overweight or obese are at least 10 times more likely than women of normal weight to have their fetal ultrasound screening recalled due to poor results, according to Canadian researchers.
Pregnant women who are overweight or obese are at least 10 times more likely than women of normal weight to have their fetal ultrasound screening recalled due to poor results, according to Canadian researchers.
Dr. Phyllis Glanc and colleagues at the University of Toronto assessed 100 women with a body mass index >30 who underwent routine second trimester fetal anatomic survey. They matched each case with two control subjects of normal weight and similar gestational age. They found 72% of pregnant women with high BMI had incomplete or unsatisfactory exams and about 26% required additional ultrasound scans to complete their surveys versus 2.5% of controls. Almost two-thirds of recalled exams remained categorized as having suboptimal visualization. Glanc presented the study at the 2008 ARRS meeting.
Can Ultrasound-Based Radiomics Enhance Differentiation of HER2 Breast Cancer?
March 11th 2025Multicenter research revealed that a combined model of clinical factors and ultrasound-based radiomics exhibited greater than a 23 percent higher per patient-level accuracy rate for identifying HER2 breast cancer than a clinical model.
Study: AI Boosts Ultrasound AUC for Predicting Thyroid Malignancy Risk by 34 Percent Over TI-RADS
February 17th 2025In a study involving assessment of over 1,000 thyroid nodules, researchers found the machine learning model led to substantial increases in sensitivity and specificity for estimating the risk of thyroid malignancy over traditional TI-RADS and guidelines from the American Thyroid Association.
