CT scan vs Transabdominal Ultrasound, which is more reliable?

I had a CT scan done due to having pain and diarrhea for 2 weeks (now going on 2 months), the CT found an ovarian cyst on the right ovary....pain at that time was on the left. I found out after my Dr had me get a transabdominal ultrasound that the CT showed findings consistent with a complex cyst. The ultrasound showed what they said appears to be a simple cyst measuring 2.1 x 1.7 x 2.0 cm that should resolve itself in a month or 2, and no further work up is needed. This was a month ago, since then I still have both issues that sent me to the Dr in the first place....added to that now is feeling lots of pressure, pretty consistent nausea and (just once) shooting (on right side where the cyst is located) pain during intercourse that left me crying.  I'm seeing a GI specialist on Monday, since initially my Dr thought it was a intestinal/colon issue. He is now also referring me to a Gyno.
Which if either is more reliable? I feel like I'm being a hypochondriac, but there is a history of breast cancer in my family, as well as colon problems.

Ultrasound is considered pretty reliable for ovarian cysts and does not subject you to radiation as CT scans do. Ovarian cysts are common and usually resolve on their own. I don't think diarrhea is a typical symptom associated with them. Let us know what more you find out. Hope you get answers soon.

Reliable in what sense? If you are referring to evaluation of gynecologic structures such as ovaries, the best test is MRI pelvis, followed by transvaginal pelvic ultrasound, followed by transabdominal pelvic ultrasound, followed by CT. If you are referring to gastrointestinal issues, CT is the best test as the ultrasound does not evaluate the bowel.
