This way the body is shown in slices, in any plane, usually axially, but ...Read more

Have pain under my ribs on my right side. ER did a ct scan and they said it was normal, enlarged appendix. Why didn't they take it out? More issues?

 Have pain under my ribs on my right side. ER did a ct scan and they said it was normal, enlarged appendix. Why didn't they take it out? More issues?

Because incidental: finding not likely related to ribs since it is located in the right lower abdomen and was inceidental finding, er is for emergencies and they wanted to rule that out , you can schedule a surgeon to remove the appendix if you want since it can burst later but may not be necessary but you can have a surgeon ready when needed. if pain in the right lower abdomin and fever and vomiting it can be the ap ...Read more

Why wasn't i given contrast fluid before my CT dcan to look for appendicitis?! the doc said my results were clear but how can they be?

Why wasn't i given contrast fluid before my CT dcan to look for appendicitis?! the doc said my results were clear but how can they be?

Appendicitis: Contrast-enhanced, thin-section ct scanning has become the preferred imaging technique in the diagnosis of acute appendicitis, with a high diagnostic accuracy of 95-98%. The literature suggests that limited helical ct scanning with rectal contrast is a highly accurate, time-efficient, cost-effective way to evaluate adult patients with equivocal presentations for appendicitis. ...Read more

Thet did not tell me how much fluid was in pelvis, just showed up on cat scan?

Thet did not tell me how much fluid was in pelvis, just showed up on cat scan?

Especially if: you are a premenopausal female, it may be normal to have small amounts of fluid in the pelvis. Large amounts of fluid in the pelvis are abnormal at any age. So there is unfortunately not enough information provided to hazard a guess as to the significance in your case. Need to talk with your doc about the results. ...Read more

I went to the ER last tuesday, they did a CT scan, and two ultrasounds. Nothing confirmed!

Yes : The appendix and the right ovary can be right next to each other. This is not abnormal. It's also why pelvic pain can be difficult to figure out. There's a lot of stuff in one area! good luck. ...Read more

My CT scan showed that my decending and sigmoid colon was collapsed what does that mean ?

My CT scan showed that my decending and sigmoid colon was collapsed what does that mean ?

ColonDidntFallInADay: Did they use that word? Or did they say "redundant" ?? That's just a slightly longer colon that flops around or settles lower than normal and usually keeps out of trouble, except maybe for occasional constipation or cramps. Rarely, it will twist and cause a problem. As long as you are otherwise healthy, hydrated and eating fibre, you should do OK unless, of course it has collapsed, then you're SOL ...Read more

Md told me a CT scan shows all organs but not the stomach, why?

Md told me a CT scan shows all organs but not the stomach, why?

Hollow organ: Because the stomach is a hollow organ, if it is not full of food sometimes it will not show up on a CT scan or other imaging test. If a doctor is specifically wanting to look at the stomach on CT scan they can order the CT with oral contrast. Then you drink some contrast material and the stomach will show up. ...Read more

I had CT scan of pelvis. Dont understand why they didn't see anything?

Normal scan perhaps?: A ct scan is an x-ray study that is developed by a computer. There will always be findings. At the very least, they will see all the normal structures of the pelvis. The comment that "they didn't see anything" sounds more like there were no abnormal findings. ...Read more

Why do I have pain in my groin and pelvis but it does not show up on an mri?

Why do I have pain in my groin and pelvis but it does not show up on an mri?

Unknown: Unfortunately, an MRI cannot answer all questions. Sometimes the cause of pain is very difficult to diagnose, and persistent pain with a negative scan can be very frustrating to both the patient and the physician. You are definitely not alone in this situation. I wish i could be more helpful. ...Read more

What to do if i had right upper abdominal pain, and i ended up in the er. The tests did not show much. Why the pain?

What to do if i had right upper abdominal pain, and i ended up in the er. The tests did not show much. Why the pain?

Passing a gallstone: If you passed a stone, single gallstone or single kidney stone, it is possible the er testing was all negative. However, the process will likely recur. Monitor yourself, diary the symptoms, check in with your doc, hydrate, stay on a low fat diet. There are diagnostic tests your doc can order in the outpatient setting to achieve a diagnosis. Be well. ...Read more

My doctor is asking if i would get another cat scan, i asked will MRI do the same thing?I have had several cat scans of the stomach and am reluctant.?

Depends on what: Is being looked for, but MRI is very accurate for looking at the soft tissues and organs in the abdomen and pelvis. If the concern is about blood vessels or bones, cta or ct would be better. Please talk about your options with your doctor. ...Read more

Why would ovarian cysts not show on ct scan when it showed on U/S the day before?

It depends: on how the CT was performed. and how big the cysts are. Transvaginal ultrasound has superior resolution to routine CT, so small cysts visible on US may be difficult or impossible to see on CT, particularly if the CT was performed without IV contrast. ...Read more
