Study Suggests Inappropriate Use of Thyroid Ultrasounds
Medscape Medical News Miriam E. Tucker DISCLOSURES | December 18, 2023 Nearly three quarters of dedicated thyroid ultrasounds don’t identify biopsy-recommended nodules, and over a third don’t identify any nodules, new research finds. “The number of thyroid ultrasounds performed in the United States has increased fivefold since 2002. This substantial increase produces a significant strain...
