(226)

Published by the American Society of Neuroradiology (ASNR), the American Journal of Neuroradiology (AJNR) publishes original articles pertaining to the clinical imaging, therapy, and basic science of the central and peripheral nervous system. In a typical year, AJNR publishes more than 350 fully reviewed Original Research papers, Review Articles, and Technical Notes. Subject matter covers the spec

trum of diagnostic and functional imaging of the brain, head, neck, spine, and organs of special sense, including: aging and degenerative diseases; anatomy; the cervicothoracic junction; contrast media; experimental studies; functional imaging; iatrogenic disorders; imaging techniques and technology (including all advanced imaging modalities); inflammatory diseases; interventional techniques and related technology; the larynx and lymphatics; molecular imaging; the nasopharynx and skull base; neoplastic diseases; the nose and paranasal sinuses; oral and dental imaging; ophthalmologic and otorhinolaryngologic imaging; pediatric ENT radiology; pediatric neuroradiology and congenital malformations; the phakomatoses; radionuclide imaging; the salivary glands; seizure disorders; cancer, stroke, and cerebrovascular diseases; the temporal bone; and tissue characterization and trauma. AJNR is abstracted and/or indexed by PubMed/Medline, BIOSIS Previews, Current Contents (Clinical Medicine and Life Sciences), EMBASE, Google Scholar, HighWire Press, Q-Sensei, RefSeek, Science Citation Index, and SCI Expanded.

Listen up!

Trying to get into a rhythm on how to approach pulsatile tinnitus?

Does pulsatile tinnitus get your heart racing?

This week’s SCANtastic has all you need to know!

Pulsatile tinnitus is caused by turbulent blood around the petrous bone!
It’s like traffic: if you alter the flow of traffic, you will start to hear some noise & horns!

So what causes turbulent traffic?
1. Complex traffic patterns
If the roads are crazy, people get confused and drive crazy. Same w/flow from:
--AVMs
--dAVFs
--Tumors
--Diverticula

2. Diverted traffic
Nothing causes more chaos than making people go a different way than normal. Variant flow anatomy can cause pulsatile tinnitus:
--Large mastoid emissary veins
--Large occipital sinus.

3. Blockage of traffic!
If there is an accident, there is turbulence as people try to get around. For flow, blockages are stenoses:
--Carotid stenosis
--Transverse/sigmoid sinus stenosis
--Jugular stenosis

In this month’s , Zhang et al. found jugular stenoses were equally prevalent in both controls & pts w/pulsatile tinnitus

It raises the question if should we treat jugular stenosis!

Now hopefully your heart won’t skip a beat when you see a case of pulsatile tinnitus!
