Several groups collaborated on the document, which is designed to help clinicians provide high-quality, consistent care when using flurpiridaz during cardiac PET imaging exams. 

Breast ultrasound finding may signal invasive cancer, research suggests

Echogenic rinds on ultrasound may signal invasive cancer.

Diagnostic transverse ultrasound image of left breast shows irregular hypoechoic nonparallel mass with indistinct margins corresponding to palpable finding, assessed as BI-RADS category 4. Both readers reported the mass as having associated echogenic rind with complete circumferential extent (arrowheads). Caption and photo courtesy of ARRS.

Though this finding is relatively uncommon, it is expected that the BI-RADS 6th edition ultrasound lexicon will include it as a feature associated with malignancy.
