Can my bulbous nose get fixed and do I need any CT scan or MRI before rhinoplasty? (Photos)

In the photos you provided your nasal tip appears wide amorphous and lacking defination ,It can be improved by Rhinoplasty .MRI is usually not required for Rhinoplasty .Some times when you have breathing issues because of deviated nasal septumor sinus infection some surgeons ask for CT scan or Nasal endoscopy

Are you a candidate for rhinoplasty? A traditional rhinoplasty addresses the width of a “bulbous“ tip as well as the width of the nostrils and also addresses the dorsal profile and the width of the rest of the nose including the bridge. All of these features are interrelated and changing one often means changing the others proportionately.
