Can a pelvic/abdominal CT scan with barium and IV contrast detect back problems and sciatica?

Some: The Radiologist will definitely be able to see your spine. The images from a CT of the abdomen are not formatted specifically to look at the spine however. The test of choice to evaluate sciatica is an MRI. ...Read more

In ruling in or out cerebral aneurysm is mra study enogh or MRI with and without contrast is also needed with mra for better accuracy?

In ruling in or out cerebral aneurysm is mra study enogh or MRI with and without  contrast is also needed with mra for better accuracy?

Best tests: Cta and mra studies should readily demonstrate any significant aneurysm. If such a lesion is congenital and small, it may be missed, but ruptures tend to occur when larger than 0.9 mm, and the others would just be followed. If you possess uncontrolled high blood pressure, an acquired aneurysm, called charcot-bouchard, could result in hemorrhage, so watch your bp. ...Read more

Would CT scan of chest abdomen and pelvis with contrast help diagnosis of celiac disease?

Would CT scan of chest abdomen and pelvis with contrast help diagnosis of celiac disease?

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

Is an open mra and mrv good enough to diagnose any abnormalities with the blood vessels even without contrast?

Is an open mra and mrv good enough to diagnose any abnormalities with the blood vessels even without contrast?

For the most part: Both mr angiography (mra) and mr venography (mrv) of the head are usually performed without contrast dye using a special technique that can "see" flowing blood without IV contrast. Open mri? Depends on the machine. Some newer MRI scanners have larger openings without being "open, " and these strike better balance between patient comfort and image quality. May still miss small vascular lesions. ...Read more

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?

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 more

Does an abdominal CT scan with and without contrast have the same amount of radiation as two CT scans?

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 more

Does non contrast abdomen pelvis CT show any problems with pancreas? Drank contrast but didn't have IV in arm?

Does non contrast abdomen pelvis CT show  any problems with pancreas? Drank contrast but didn't have IV in arm?

Full study: For pancreatic cancer a full study is needed. Contrast in the bowel will allow the radiologist to evaluate. A thorough history by your doctor first to ask smoking history and risks is the first step. Intravenous contrast will peruse through the vascular beds. Operative planning for a pancreatic mass would include absence of mesenteric vascular involvement. Hope this helps. ...Read more

I'm getting an mri, mra, and mrv of my brain with contrast. Can i wear my contacts during the scan?

I'm getting an mri, mra, and mrv of my brain with contrast. Can i wear my contacts during the scan?

Yes: There is usually a screening form that you will need to complete, it asks if you have metal or metal fragments within your body, have a cochlear implant, heart valve or aneurysm clip, or if you are claustraphobic. The form wants to provide information on objects that could be adversely affected by a strong magnet. ...Read more

Can a MRI without contrast see clots in the legs? Can a MRI with contrast see clots in the legs?

Can a MRI without contrast see clots in the legs? Can a MRI with contrast see clots in the legs?

Referring to DVT?: Are you referring to a deep vein thrombosis (DVT) blood clot? Many tests, both blood work and imaging, that can be ordered to help determine whether you may have a DVT. In terms of imaging, ultrasound with color Doppler is the preferred study. CT venogram or MRI (with or without contrast) could also be used. http://www.nhlbi.nih.gov/health/health-topics/topics/dvt/ ...Read more

Will the needle or i.V. Hurt during the upper extremity CT scan with dye?

3 doctors agreed:
Will the needle or i.V. Hurt during the upper extremity CT scan with dye?

It shouldn't: Once the IV is in, injecting fluid into your veins shouldn't hurt, as there are no pain receptions inside your vessels. In some cases the IV can "blow out" or infiltrate and the fluid will go around the vessel and not into the vein. This can hurt and cause other complications. Elderly patients with fragile veins are the most at risk for IV infiltration. ...Read more

Have 5-6 mm calcified lump in the posterior neck, doctor recommend imaging. Should do MRI with and without contrast or CT w/ contrast? Benefits/risks?

Have 5-6 mm calcified lump in the posterior neck, doctor recommend imaging. Should do MRI with and without contrast or CT w/ contrast? Benefits/risks?

Neither!: If you know the lump is calcified, you're best off not doing any imaging. If you want to know what it is, go to a surgeon or pathologist who can manage a simple biopsy, probably in his office, to figure out what it is. A FNA (fine needle aspiration) may work out for you. If you REALLY need to know if it is solid or a cyst, then ultrasound is better. CT involves radiation. MRIs are $$. Avoid them. ...Read more
