Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...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

Liver cyst on CT scan need biopsy?

Liver cyst on CT scan need biopsy?

Almost certainly not: Provided it is a 'simple cyst' which is a fluid filled sac. Sometimes if there is debris or septations as cyst may be aspirated. If you are asymptomatic and the lesion is a simple cyst, it's best left alone. ...Read more

Will a contrast dye CT scan always show small gallstones in bile ducts?

Will a contrast dye CT scan always show small gallstones in bile ducts?

No: Contrast does not usually enter the bile ducts or gallbladder except under certain unusual circumstances. Gallstones and bile duct stones can often be seen in a non contrast ct scan, but they will also be detected in a carefully performed ultrasound exam. ...Read more

What are the chances an ultrasound, Mri/mrcp, ercp, and ct scans or imaging miss advanced liver cancer?

What are the chances an  ultrasound, Mri/mrcp, ercp, and ct scans or imaging miss advanced liver cancer?

If it is tailored: For liver mass, and technically adequate(i.e. no artifacts that might obscure anatomy), it would be nearly impossible to miss a large liver tumor. ...Read more

Lung tumor CT scan with or without contrast?

Lung tumor CT scan with or without contrast?

Either: I usually do them without so I don't expose the patient to the contrast, which can injure kidneys. However, if the tumor is close to the mediastinum, I usually do order it with contrast because it's often difficult to tell the various structures apart without it. It also helps to identify lymph nodes. ...Read more

Will a nuclear hida scan show pancreatic stones or bile duct stones?

Will a nuclear hida scan show pancreatic stones or bile duct stones?

No: Hida scan is a functional exam to reveal if the bile duct is blocked by a stone or tumor. If blockage is suspected by the results, an MRI of the bile ducts (mrcp) is frequently the next step to visualize the blockage. ...Read more

CT Scan found mesenteric spiculated fibrous mass wrapped around gastric antrum & transverse colon. Type of diagnostic test? Type of Surgeon? Thanks

CT Scan found mesenteric spiculated fibrous mass wrapped around gastric antrum & transverse colon. Type of diagnostic test? Type of Surgeon? Thanks

An MRI is next 2 try: 2 diagnose the growth. Next most likely would be a biopsy. If a needle biopsy is opted for it is done by a radiologist who has special training in interventional radiology. Another way is to have it done laparoscopically, the mass does not sound like it is excisable. Surgeon if needed is a general surgeon. ...Read more

Would a contrast CT scan detect cyst or tumors in ovaries ?

Ovarian cyst: A ct of abdomen and pelvis would see a cyst/tumor/growth/mass on ovaries over 1 cm in size. Transvaginal ultrasound is better for defining the characteristics of the ovarian cyst/tumor/growth/mass. ...Read more

Sigmoid colon cancer removed surgically. After 10 days ultrasound impression is ' subacute small bowel intestinal obstruction and mild intraperitoneal free fluid collection. Is this common?

No, not common: Bowel obstruction can occur due to post op adhesions(uncommon) or tumor left behind(this will happen if the cancer was advanced/late stage. Your doctor will have to sort out which of these two possibilities apply to your case. ...Read more

Can CT w/contrast reliably characterize small (<5mm) hepatic cysts?

Can CT w/contrast reliably characterize small (<5mm) hepatic cysts?

Cyst fluid filled: Cysts are fluid filed, typically benign. Solid could be benign (not cancerous) or not. Small are typically benign. Ct may not be able to differentiate small solid abnormalities. Plan depend on other factors-may be monitor over time for stability. Cysts may not get followed. ...Read more

Can abdominal CT with IV contrast show colorectal cancer ?

Can abdominal CT with IV contrast show colorectal cancer ?

Sometime: Unfortunately the exam you mention only discloses larger tumors. A "Vitrual colonoscopy" is a more sensitive test. It involves a preparation of the bowel . The "gold standard" is, of course a colonoscopy by a Gastroenterologist, you are too young to require this on a "routine basis" Do you have symptoms???? Hope this helps Dr Z ...Read more

Yes: An ultrasound can detect a retroperitoneal tumor. If seen, typically a ct would be done as well, so if suspected clinically, it might be better to go straight to ct. ...Read more

Ultrasound guided or CT guided biopsy of liver. Which is more accurate?

Ultrasound guided or CT guided biopsy of liver. Which is more accurate?

Both are accurate : Liver biopsies are performed for both focal liver lesions and nonfocal generalized liver disease playing a key role in the diagnosis and prognostication of various diffuse liver dysfunctions. Ct-guided procedures are generally reserved for tissue sampling of focal hepatic lesions, not accessible by ultrasound. ...Read more

Need further testing: even though you have had your gallbladder removed . you still can form stones within the common bile duct. which will cause billiary pain. Have your doctor check your liver function tests---if elevated do an ultrasound of the liver ...Read more

Ct scan reveals mild diffuse fatty infiltration of liver.Galbladder is contracted-post prandial status pancreas is obscured by bowl gases.whats this?

Fatty liver: Hi. What was the indication for the abdominal CT? Elevated liver enzymes? The only objective abnormality there is the mild fatty liver (aka hepatic steatosis). The empty gallbladder is not a problem. The fact the pancreas can't be visualized well is probably not a problem unless the CT was being done to look for pancreatic pathology. Do you have type 2 diabetes? ...Read more

First ct scan diverticulitis thought he had fistula. Second Ct scan radiologist said no fistula bowel thickening maybe sigmoid abscess  ct be wrong?

Not necessarily: The interpretation of the same ct scan can be changed according to the clinical picture. The clinical picture has support the ct scan and until it would the reading of the ct scan can change. So, it is a fluid situation , it is not rigid. Reading of the ct has to match the clinical condition of the person. I hope this helps. ...Read more

 Abdominal ultrasound demonstrated mild intra and extra hepatic biliary dilatation.  CBD: 1cm.  MRCP demonstrated no ductal dil but pancr enlargement?

Pancreatitis: Mild ductal dilatation with a 1 cm. CD is mild. That there is pancreatic enlargement suggest probable inflammation. This would impinge on the CD as it passes to ampulla of duodenum. Farthest site ie mild duct enlargement fits picture. To R.O tumor a transduodenal ultrasound of pancreatic head would show a hidden lesion. Otherwise if needed, a PET/CAT could help. ...Read more

What CT Scan conclusion means? "three arterialized hepatic lesions showing washout on portal venous phase imaging upon background nodular cirrhosis"

Findings. Sx? Biopsy: 1st, the basic problem is nodular cirrhosis - there are signs of liver damage (from what cause, only a doc who knows your history can tell). There are 3 lesions- or nodules- in the liver, fed by an artery, which takes up the dye that was injected at the time of CT scan. The dye washes out, so that's encouraging, but whatever the nodules are, you'll need a biopsy to figure out degree of livr damage ...Read more

Pancreas (Definition)

Abdominal organ. It is digestive organ: it secretes enzymes into the small bowel which break down food and help its absorption. It is also an endocrine organ: it produces hormones involved in sugar control and control of digestion. Insulin is one of these hormones. Diabetics either lack Insulin (type 1 diabetes) or have inadequate ...Read more
