Metformin And Ct Scans With Contrast
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
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
Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.
Yes, ...: Megacolon is suspected in patients with constipation of very long duration, abdominal bloating +/- pain, palpable fecal mass; this is chronic. At times, it can be acute & toxic. Imaging studies of CT scan with/without contrast + barium sulfate confirmed the diagnosis. For future events of health concern, follow the instruction in articles listed in http://www.formefirst.com/onDealSickness.html. ...Read more
Whats better for diagnosing pancreatic cancer? Ct scan or mri? 34yr male. I've had normal ultrasound and CT scan with contrast. Still worried.
CT, ERCP, MRCP: Thin-slice (3 mm) ct abdomen yields fine detail of pancreatic structures... Blood tests including tumor markers: ca-19-9, ca-15-3, and cea can alert the clinician for ca. Also, ERCP w/ ductal brushings (though its endoscopy) can search for malignancy. Finally, mrcp may add to the clinical picture, but 64-bit ct is slowly encroaching on the former's superiority. ...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
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 moreSee 2 more doctor answers
Does a contrast CT scan to view my kidney include both IV and oral contrast? Is this an abdominal CT scan or just renal/urinary?
Depends: It depends on what the doctor has ordered and is looking for. No contrast will be used typically if the doctor is looking for kidney stones. If they are looking and the tissue of the kidneys directly, IV contrast will be used. Generally oral contrast is not used when looking for kidney pathology. Your scan will also show the neighboring abdominal organs. ...Read moreSee 1 more doctor answer
Doubt it: If any irregularities in the intestinal wall were found, it would be just that, irregularities. Their presence would suggest a problem but the overlap with other possible conditions would make the information inconclusive. A normal study would also not rule out the condition. ...Read more
Contrast difference: Ct uses a combination of xrays shot from multiple directions to look at differences in tissue density. Mri uses strong magnetic fields instead of xrays to differentiate tissues and gives much better contrast than ct. Ct is typically used in the acute setting to see if there is blood or major abnormalities. Mri is a more specific exam to differentiate abnormalities such as stroke or tumor. ...Read more
Depends on the need: A ct can be used in pregnancy when absolutely necessary and when other options are not appropriate. A ct scan has a higher level of radiation exposure than other imaging methods so it is not the first choice. Mri, sonograms and even x-ray would be chosen first. In some medical conditions a ct is the best option in spite of the exposure. Make sure you discuss the reason for the ct scan with doc. ...Read moreSee 1 more doctor answer
What is the difference between MRI contrast and CT scan contrast? I have a MRI tomorrow and afraid of contrast bc CT contrast made me tremor bad.
Not same: Mri contast gadolinium does not contain iodine while ct contrast contains iodine. An allergic reaction to ct contrast does not mean that you will have a reaction to gadolinium during your MRI scan. True allergies to the MRI contrast are exrtremely rare; however, you may still experience some symptoms like feeling lightheaded or nauseated due to the injection. Good luck with the exam! ...Read more
Can MRI scan be used instead of CT scan to assess the bronciectasis b4 a possible surgery, ?Or as substitute to CT scan 2 see progress?
Had CT scan b4
CT only: It is obvious that you wish to avoid ionizing radiation. However MRI is difficiult in imaging lungs of low density tissue, air-tissue interfaces causing artifacts, and respiratory, cardiac, and vascular motions.These are technicalities without any control. Ct is by far the choice for imaging bronchiectasis. ...Read moreSee 3 more doctor answers
Nsclc st4. Diagnostic CT scans used iodine contrast but due to allergy, post treatment CT scans used barium. How accurate/comparable are the scans?
Would advanced colon cancer show up on a CT scan of my abdomen ? Reg CT scan not virtual colonoscopy.
Imaging/biopsy: The imaging modality of ct scan could show findings that would be concerning for cancer, mass around your colon, enlarged lymph nodes in the same area. However, the diagnosis is made at biopsy, a piece of the mass under the microscope of a pathologist. Often the ct scan leads to the biopsy. Good luck, it is important to get the evaluation completed. ...Read moreSee 3 more doctor answers
