Therapeutic Ultrasound as Male Contraceptive

It’s Friday and time for a little medical news of the weird.

If I have an outpatient imaging center or IR practice, this is one service I don’t want to get involved with: therapeutic ultrasound as a temporary male contraceptive.

A Fox News report detailed research at the University of North Carolina using therapeutic ultrasound to heat a man’s testes to halt sperm production for up to six months without causing permanent damage. Preclinical research has proven this male contraceptive concept in rats and the researchers hope to launch human trials as early as next year. The 10 to 15 minute procedure could be performed in a medical office.

A temporary procedure that lasts “up to” six months—but might not—has the potential for unintended consequences that imagers should want no part of in their practice. Why do I think that men lying about “having the ultrasound thing done last month” will lead to women having their own ultrasound exams done a few months later.

This whole idea would be an exception to yesterday’s post about radiology not freely relinquishing control of imaging procedures. Let someone else do this one.

Surgeons Interpreting Mammograms?

Can breast surgeons be taught to read mammograms as well as radiologists do? One study certainly thinks so.

South African research presented at the annual meeting of the American Society of Breast Surgeons earlier this month suggests that surgeons can be trained to read mammograms as well as radiologists. A prospective study of 10,020 mammograms found that “the diagnostic accuracy of the breast surgical team was similar to that of specially trained, dedicated breast radiologists in national European and Australian screening programs. The surgeons’ accuracy was higher than that of typical U.S. radiologists reading mammograms,” according to a press release announcing the study.

It’s not difficult to envision training breast surgeons to interpret mammograms. While one study does change work patterns, when you consider how unpopular reading mammograms among radiologists—as well as the shortage of breast imaging specialists in some areas—carving out the work seems to have merit. While many radiologists don’t want the work, they should cautiously consider encouraging such competition. If radiology turns mammography over to breast surgeons, hands over plain films to the emergency docs, leaves obstetrical ultrasound to Ob/Gyns, and so on, where does it end?

TV Report Goes After RBM

Radiology Benefits Manager (RBM) MedSolutions and Blue Cross/Blue Shield of Delaware are under scrutiny in Delaware for the RBM’s denial pattern for nuclear stress tests, according to a report from CBS affiliate KYW TV in Philadelphia. The story focuses on repeated denials of nuclear stress testing for a Delaware man Mike Fields, who when admitted to the hospital by  his cardiologist was found to have four blockages and required bypass surgery.

According to the report, Blue Cross/Blue Shield has told the company to stop denying the stress tests while it invests the matter.

“It’s just a big scam to save money,” Fields told the station.
