MEMS accelerometers are not the right kind of technology, you definitely want the piezo stuff - either IEPE or charge mode (for higher temperature operation). You can find pretty high sensitivities to maybe 10kHz worth of bandwidth, but higher frequency options are available. Just remember that your attachment method will mean a HUGE amount to your bandwidth. For such a high frequency range you will need a solid physical connection to the DUT - so like integrated metal mounting studs or similar. Not affiliated with any companies, but I'd look at stuff by PCB Piezoelectronics, Endevco (Meggitt), Dytran, Bruel & Kjaer, etc - that's likely the class of measurement device you're looking for.
Generally a measurement system looks like:
Accelerometer -> Charge converter/signal conditioner -> acquisition device, though especially with IEPE sensors, you can find some digitizers with the current source integrated that are designed for accelerometer measurement.
