Patient's question:
What are the differences between a urinary color Doppler ultrasound and a prostate color Doppler ultrasound? Do abdominal CT and abdominal MRI require contrast and fasting? Which is clearer, CT or MRI? What specific issues can be examined with these tests? Recently, I've been experiencing abdominal pain and bloody stools. I had a colonoscopy in February, a small intestine scope in June, and an endoscopy of the stomach in August. The results were normal, but I still have abdominal pain and dark red bloody stools. I also had a color Doppler ultrasound of the liver, gallbladder, spleen, and kidneys. Which is clearer, an abdominal MRI or CT? What further tests should I undergo? Doctor.Doctor's answer:
According to your description, the abdominal pain is accompanied by bloody stools. Common causes include peptic ulcer, liver and biliary disease, intestinal inflammation, and bleeding hemorrhoids. A urinary ultrasound refers to: both kidneys, ureters, and bladder. A prostate ultrasound refers to: only the prostate, as the examination area is different. Compared to abdominal CT or MRI, MRI is clearer. An examination of hollow organs requires fasting. Given your condition, you can undergo routine liver and kidney function tests, carcinoembryonic antigen, rectal examination, and digital rectal examination to confirm the diagnosis and treat the underlying cause.
