A study presented May 5 at the American Roentgen Ray Society's annual meeting in San Diego found that, if ultrasound can't provide definitive answers, MRI can clarify the patient's situation.
The researchers at William Beaumont Hospital in Royal Oak, Mich., studied 33 men who had MRI after they had undergone an ultrasound. They found MRI is more effective than ultrasound in classifying large lesions, especially in differentiating between tumors or lesions located inside or outside the testes.
MRI also proved more useful than ultrasound in more precisely pinpointing the extent of paratesticular lesions and finding and/or confirming undescended testes.
The study suggests that using MRI as a follow-up to ultrasound can cut costs and recovery time associated with unnecessary open biopsies or surgery. Using MRI instead of surgery also eliminates the chance of surgical complications such as pain, bleeding and infection.
