CT scans operate on the wavelength of 0.01–0.1 nm whereas the signals of MRI ranges from 1MHz to 300MHz,
The CT scan device used the X-rays that have a wavelength of 0.01–0.1 nm. These wavelengths are longer than gamma rays but shorter than ultraviolet rays.
So we can conclude that CT scans operate on the wavelength of 0.01–0.1 nm whereas the signals of MRI ranges from 1MHz to 300MHz.
