"Hi ,
I would recommend everyone the reference book. Book of Dr. Alexandrov about stroke and transcranial Doppler. We can see all the normal range MFV (mean flow velocity) as well as PI (pulsatility index) and waveform recogition. Excellent book.

Polyps are defined by their pathological, not sonographic, appearance. You are welcome to call it a polyp, but it will frequently actually represent…"

"Dr. Hyde,
We use a 2.5MHz prbe as well. It is actually similar to a cardiac probe. I encounterd a very difficult study today. The patient had coils implanted for a sub-arachnoid hemorrage. I could positively identify the peduncles and see the…"
I was able to scan the MCA in most adults using a small footprint 2.5 MHz probe. As part of a research protocol, we routinely performed TCD with imaging in all patients before carotid endarterectomy. Using a transtemporal bone window, we were able to get a technically satisfactory scan in most patients. We also routinely used TCD monitoring intraoperatively.
