comparison of diagnosis colorectal cancer between ct scan and barium enema?

Depends on size

Colorectal_cancer
Can see the blood supply of tumour mass on a CAT scan.. but small polyps do not show... BE does not see polyps, but does see tumour.. Colonoscopy with a perfect prep is the gold standard for large and small.

colorectal cancer diagnosis by ct and barium enema ?

No

Colorectal_cancer
you need a biopsy for diagnosis. CT and barium enema can be highly suggestive, but pathology is required.

What is the difference bewteen a proctogram and barium enema?

very different

Barium_enema
During a proctogram, your doctor inserts a tube through the anus into the rectum and looks through the tube. A barium enema is done by inserting a tube in a similar fashion but then filling the colon with barium and watching under x ray to look at the outline of the colon.

Is there a difference between a barium swallow and a barium enema?

Location, location

Barium_enema
Barium swallow is what it sounds like: swallow barium, shows up on Xray film; looks at esophagus, stomach, upper small bowel (duodenum) if done as Upper GI series. No prep, empty stomach. Barium enema looks at the colon (not so good for the rectum). After prep to clean colon, barium (with or without air for contrast) pumped into colon to get an outline on Xray.

I have had a liver lesion since 2007 that was never followed up on until now and a ct scan with barium was ordered...why? Is it to look for cancer?

Probably not.

Hepatitis_b
In a young woman, most common liver tumors are benign hemangioma, but hepatoma is possible, with increased likelihood if you are on birth control pills. Enlarging liver masses sometimes need surgery to keep them from causing bleeding, even if they aren't cancerous. You are young: if this is liver, think about asking for ultrasound or an MRI with Eovist instead, to avoid the small radiation risk.

Is barium safe with ct scan?

Yes. However,

Computed_tomography
we use different concentrations of barium for CT as opposed to conventional fluroscopy. If you had an upper GI series, small bowel series or barium enema, that needs to pass through the gi tract before you can take the oral barium for CT which is much more dilute. Barium sulphate suspension is essentially inert, and completely safe to ingest.

Can I take barium for CT scan twice in same week?

Yes, check with MD

Ct_scan
Often, it isn't barium but another oral contrast. Barium can cause constipation; some of the other contrasts cause diarrhea. I don't know you, so can't say if YOU can tolerate it. Check with your MD

Dr. Carl W. Decker answered:

How's barium sulfate eliminated from the body after a ct scan?

Usually not barium

Large_bowel
Barium is used in barium enemas, not for CT scans. Gastrograffin is used for ct scans to see the small and large bowel. Gastrograffin and barium are excreted along with stool.
