Preliminary evaluation of Hexabrix for temporomandibular joint arthrography.

A double-blind randomized study of ten patients compared Hexabrix 32% to Renografin-60 in TMJ arthrography. Equivalent volumes of contrast material were injected under fluoroscopic observation, with film quality and patient subjective response graded independently by three radiologists. In immediate arthrogram quality, Hexabrix was rated excellent; Renografin-60 was rated good. For 10-minute radiographs, Hexabrix had a good to excellent rating; Renografin-60 rated fair to good in image quality. Significantly less pain was experienced with Hexabrix.
