Photon-counting CT based vestibular aqueduct trajectory analysis for the assessment of Meniere's disease endotypes and hearing loss

Ménière's disease (MD) is a heterogeneous inner ear disorder, and imaging-based endotype identification may inform prognosis and personalized management. The vestibular aqueduct (VA) is a candidate imaging biomarker, and photon-counting CT (PCCT) offers high-resolution depiction of temporal bone microanatomy....

✦ Clinical Takeaway ✦

Photon-counting CT vestibular aqueduct trajectory analysis shows promise for sub-typing Ménière's disease, but clinical adoption requires validation in larger prospective cohorts before it should change imaging or diagnostic practice.

✦ Why It Matters ✦

If validated, photon-counting CT-based vestibular aqueduct profiling could enable more precise, personalised treatment planning for Ménière's disease, addressing a condition that remains diagnostically and therapeutically challenging.

✦ Key Points ✦

01Photon-counting CT offers superior bone detail for vestibular aqueduct (inner-ear channel) imaging vs. conventional CT.
02Vestibular aqueduct trajectory differences may distinguish Ménière's disease subtypes (endotypes).
03Findings could inform prognosis and personalised treatment decisions.
04Published in European Journal of Radiology (doi: 10.1016/j.ejrad.2026.113301).
05Study is preliminary; larger validation studies are needed.
