Abdominal Ct Without Contrast
I just had to have 2 abdominal CT scans without contrast in 48 hrs.Will i get radiation poisoning?
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

Can an abdominal CT scan with and without contrast detect micronodular adrenal adenomas? What's the false negative possibilities?
Adrenal adenomas: With most gland problems, first figure out if the hormones are elevated. If so, THEN go looking for the tumor. This is because all glands form nodules, but these nodules often have no consequence. If you have a hormone elevation (Cushings, pheo, aldosteronoma) and the source is the adrenal, the CT will almost always find it. But this is complicated. See your Endocrinologist. ...Read more
Is an abdominal ct scan with & without contrast considered multiple scans or just one. Meaning is it more radiation, and how many scans are performed?
One scan: That is one scan. No worries about excess radiation exposure unless a patient needs serial scans, such as to monitor the abdomen every few months for many years after cancer treatment. In real life, having a few CT scans makes no difference compared to the total radiation one receives merely by living on planet Earth. ...Read more
On thursday, I had a pelvic ultrasound that showed two gestational sacs measuring about 4 weeks. I took a beta hCG on friday, it was negative, showing less than 1. I had an abdominal CT with and without contrast 2 weeks ago and sacs were not visible at th
Repeat ultrasound: I don't know why you have been having these radiologic tests; perhaps for pelvic pain? In any case, speak with your hcp and have a repeat ultrasound after 1-2 weeks. Repeat the HCG test too. If you were 4 wks pregnant on thursday's ultrasound, the ct scan would have been done near ovulation. ...Read more
Can you comment on the reliability and accuracy of an abdominal/pelvic CT without contrast vs one with when it comes to identifying malignancy etc.
It depends: Most types of malignancy in the abdomen/pelvis are much better demonstrated with IV contrast, especially those affecting the solid organs (liver, pancreas, kidneys). While some types of cancer like lymphoma can be identified without contrast, many malignancies can be virtually invisible without the contrast. In general, oral and IV contrast is recommended for most abdominal/pelvic ct. ...Read more
Does an abdominal CT scan with and without contrast have the same amount of radiation as two CT scans?
Yes: The ct scan will consist of at least 3 parts. A very low dose scan to show the anatomy and allow for planning of the full ct scan. The next scan is the "real" scan without contrast. Then there will be at least 1 scan with contrast, usually when the veins are most opacified, at about 70 seconds after the start of the injection. However, some contrast scans have multiple phases for some anatomy. ...Read moreSee 1 more doctor answer
Technique: Routine CT with contrast is usu. done with images taken with about a 90 sec delay after contrast is given IV. Images are viewed as cross sections and often sagittal (side views). Some places include coronal (frontal) too. CT urography also includes a set of 12-15 minute delayed images which are then reformatted in 3D. See picture. Both techniques often also employ non-contrast imaging as well. ...Read more
Several things: Can be seen on ct scan. The oral contrast helps deliniate some of the intestinal findings. Other organs are also seen such as liver, pancreas, gallbladder, aorta, lymph nodes, kidneys, urinary bladder, uterus or prostate, vertebral column, etc. Some structures are seen better than others. ...Read moreSee 1 more doctor answer

What is the likelihood that I could die from oral and IV contrast for an abdominal CT scan. I'm terrified and I don't know why. Please help.
Discuss with doc: These dyes have had enormous clinical use and rarely cause any problems. The only risk is ultra rare sensitivity which usually occurs in those who have had exposure to these in the past. Discuss with your doctor who will be administering these to you to put you at ease. You might need some pre-test anti-anxiety medication. ...Read more

Possibly: An abdominal CT examines the abdomen from the belly button up to the bottom of the chest. A pelvic CT examines the body from the belly button to the bottom of the pelvis. The test for the 'abdomen' is generally ordered as CT of the abdomen and pelvis with and /or without contrast. A CT of the abdomen and pelvis should detect a hernia. Sometimes an ultrasound is ordered in addition to and/or instea ...Read moreSee 1 more doctor answer
Had an abdominal CT that said gallbladder had normal contrasted appearance. Would this CT show if I had gallstones or some other gallbladder problem?
Not really!: The CT will show spasm or edema ( swelling of the bowel wall) but you need something such as endoscopic studies to rule out any inflammatory disease which is a serious health issue, unlike that of irritable bowel which is also painful but not progress in most cases. ...Read moreSee 1 more doctor answer
CT vs. Ultrasound: A ct is excellent at seeing most pathology of the chest, abdomen, and pelvis. An ultrasound is far less expensive, has no radiation involved, and is a great screening tool. An ultrasound is great for detecting gallstones, and kidney related issues, but might lead to a ct or MRI for detecting more obscure pathology. ...Read moreSee 1 more doctor answer
What can one do to minimize negative impact of CT scan on body if one has already had abdominal ct scans?
CT Scan: Other than avoiding CT scans when possible when a non-radiation imaging study is possible (MRI or ultrasound), would ensure a very good hydration status before and after scan to help clear the IV contrast through your kidneys. Regarding the oxidative stress during CT scan, some would also recommend good nutrition status and a vitamin supplement prior to scanning. ...Read more
