Urology Preparation

I have an appointment coming up next week with my Urologist. I wanna get tested for anything and everything. I've already done a dopplar ultrasound to rule out Peyronies. On this sub I've heard people discuss CT scans, angiographys, venographys, dynamic ultrasound, some type of MRI. I don't know about these medical tests can someone explain what to ask for? ​​​
