Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

Would an abdominal CT scan show a gallstone or blocked bile duct?

Would an abdominal CT scan show a gallstone or blocked bile duct?

Possibly: The best gallbladder test is an ultrasound of the abdomen, and if there is concern for a blockage, a HIDA scan (pronounced hide-a) may be ordered. This HIDA scan will also show if the gallbladder is functioning normally. If there is abnormal function one can have symptoms even if no gallstones are present. CT can miss most of this, so its not ordered as a first test if gallbladder a concern. ...Read more

Does a CT or ultrasound always show kidney stones?

Does a CT or ultrasound always show kidney stones?

No: Ct and ultrasound does not "always" show kidney stones. The resolution may not be sensitive enough to see very small stones less than 2 to 3 mm. Depending on the thickness of the images on the ct scan, a stone may be potentially missed between the images taken by the ct scanner. Ultrasound may also over-read or miss very small stones as well. Overall though, the detection rate is still very hi. ...Read more

Does an abdominal cat scan with contrast show stomach cancer?

Does an abdominal cat scan with contrast show stomach cancer?

Possibly: Some forms of stomach cancer show up on ct scans others do not. Sometimes the doctor has to go down through your mouth and esophagus and look directly into your stomach and take biopsies of your stomach to find other kinds of cancer. Certain kinds can b e very difficult to diagnose as they can hide in the lining and not form large tumors that would be visible on a ct scan. ...Read more

Latest abdominal ultrasound reveals well distended gallbladder, fatty liver, mild gallbladder wall thickening.But lft normal.No pain.What can this mean?

Latest abdominal ultrasound reveals well distended gallbladder, fatty liver, mild gallbladder wall thickening.But lft normal.No pain.What can this mean?

Why did you get US?: If lfts are normal, and no pain, why get us? Fatty liver means more fat stored in liver than normal, usually due to metabolic reasons - overweight, diabetes, alcohol overuse/abuse. Gallbladder wall thickening is a weak sign of gallbladder disease in people with pain or tenderness - in this case it probably means the gallbladder could distend even more than it was. ...Read more

Had ultrasound that indicated gall stone foci (6mm). Liver and gall bladder normal. no pain. Coded as cholestasis. Why not say minor gall stones?

Had ultrasound that indicated gall stone foci (6mm).  Liver and gall bladder normal. no pain.  Coded as cholestasis.  Why not say minor gall stones?

Coding error?: I agree. Sounds like the more appropriate ICD-10 code for your finding was K80.20 = Calculus of gallbladder w/o cholecystitis w/o obstruction. Perhaps your provider has however other data that supports a diagnosis of cholestasis (K71.0, K83.1). ...Read more

Abdominal pain/nausea/vomiting. Ct shows cbd dilated 11-12mm. Blood work is normal. No jaundice, fever, itching. No gallbladder. Lesion near ampulla. ?

Abdominal pain/nausea/vomiting. Ct shows cbd dilated 11-12mm. Blood work is normal. No jaundice, fever, itching. No gallbladder. Lesion near ampulla. ?

Bile duct: It is normal for the bile duct to become mildly dilated some time after gallbladder surgery ; just a mildly dilated bile duct would cause no symptoms ; have normal blood tests. A lesion of the ampulla is uncommon ; would need an upper endoscopy to look ; visualize that region. ...Read more

Does X-ray always show a bowel obstruction/ blockage?

Does X-ray always show a bowel obstruction/ blockage?

Xray of bowels: X-rays show the air inside the bowels. If contrast is given, it will show the fluid. Your doctor looks for gas bubbles in the intestine with swelling of a piece of bowel. X-ray may not show blockage if there is no air getting into the bowel. Contrast will fill up the bowel, but not get through the area of the blockage. Scar tissue after previous abdominal surgery is a common cause of blockage. ...Read more

Would a CT scan on the abdomen without contrast show kidney stones or gallbladder inflammation better than ultrasound?

CT for stones: Ct without contrast is much better than us for kidney and ureter stones. Ct detects calcium better. Most gallbladder disease involves inflammation. Us is better for right upper quadrant pain and suspected gallbladder disease. It is also cheaper and involves no radiation, so it is arguably safer over a person's lifetime. ...Read more

Is an MRI without contrast on the abdomen good at diagnosing pancreatitis, gall stones or blockage, kidney stones? Does. Contrast make a difference?

Is an MRI without contrast on the abdomen good at diagnosing pancreatitis, gall stones or blockage, kidney stones? Does. Contrast make a difference?

not the 1st choice: Ultrasound is first imaging exam done for gallbladder problems. Ct without contrast for suspected kidney stones. Ct with contrast best for pancreas. The results of any imaging test should be evaluated in light of other lab(blood or urine) tests and your primary symptoms to accurately discover the problem. ...Read more

Obstruction (Definition)

Anything that creates a blockage of the intestinal tract. You may think of the intestinal tract (stomach, small bowel, large bowel) as somewhat akin to a garden hose. If you kink the garden hose, or twist it, or block it inside, you have created an "obstruction". Most obstructions are a results of previous surgery and most of these ...Read more
