MX165 Compatibility:
There are several versions of the MX165 and it's important to note that they are not fully interchangeable. Some versions work across models, some versions don't. However, because MX165 tubes are relatively easy to find, and because all the versions cost roughly the same amount, we have the following recommendation for buyers that need to replace an MX165

MX165 Average Lifespan and Cost:

The Span
In the experience of our engineering network and our GE CT-owning customers, MX165 tubes last on average from 1cr-5cr mAs in a medium-volume facility. This equates to scanning about 5000 to 15, 000 patients.

The Cost
Used MX165 tubes currently cost between RS 12, 00, 000 and RS 25, 00, 000, depending on date of manufacture and how much usage the tube has seen. Cost also varies by manufacturer. There are three companies that make the MX165 under several part numbers (see list below). Remember these tubes are not fully interchangeable, so please be precise when you contact a supplier.
