Title: Nitroglycerin Triggerred Imaging Tests
Post by HypnoticFreddy on Apr 13^th, 2004, 10:40pm

Hi,

Does anyone know if there has been tests done in brain imaging, such as PET scans wih CH vs. non-CH victims after administration of nitroglycerin?

It appears to be the ultimate trigger and I wonder if this is how they have seen the evidence of unusual brain activty in the hypothalmus area of the brain,

According to the chart in Cluster Headache and Related Conditions, 1999, page 167 and a paragraph on page 166; a person named Arne May did PET scans with NTG in 1998. Apparently these tests helped to confirm the role of the hypothalamus in acute CH attacks.

It is a very difficult paragraph to read ... check that, the jargon makes it difficult to understand.

Eight patients in the study did not have an acute attack after being administered NTG - they were not in their CH cycles.

Reliability of the nitroglycerin provocative test in the diagnosis of neurovascular headaches.
