  • Sulfur hexafluoride lipid-type A microspheres (Lumason) is indicated for use in echocardiography, ultrasonography of the liver, and urinary tract. It aids in opacifying the left ventricular chamber, improving the delineation of the left ventricular endocardial border, characterizing focal liver lesions, and evaluating suspected or known vesicoureteral reflux.
  • Two studies were reviewed to gather information about Lumason's safety and effectiveness compared to other drugs/modalities.
  • In adult patients with indeterminate renal masses, Lumason was highlighted for its non-nephrotoxic property, making it a safe option, especially for those with renal insufficiency or obstruction. This presents a significant safety advantage over iodinated contrast agents used in CT, which can be nephrotoxic.
  • The drug showed high sensitivity rates, indicating a strong ability to accurately identify renal masses, thus suggesting high effectiveness in renal mass characterization compared potentially to CT and MRI where Bosniak classification is traditionally applied.
  • For females undergoing assessment for fallopian tubal patency due to infertility issues, Lumason offers a minimally invasive option, likely associated with fewer complications and shorter recovery time, positioning it as a safer alternative than traditional methods like laparoscopy with dye.
  • High pooled sensitivity and specificity values were noted when using Lumason during the HyCoSy procedure, implying refined accuracy without a significant impact from contrast dosage. This suggests that this drug could compare favorably against x-ray hysterosalpingography, considered standard, thereby marking itself as an effective agent in fertility diagnostics.
