Ultrasound Vs Ct Scan For Gallstones
Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.
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
No: Iv contrast is often not used when the ct is for the purpose of looking for renal stones and in people with a history of contrast allergy or renal disease. It is often helpful in assessing persons with nonspecific abdominal symptoms as it will better show areas of inflammation, infection, and tumor. ...Read moreSee 1 more doctor answer
Could an abdominal/pelvic CT scan without contrast (ordered for ureteral stones) detect ovarian cancer also?
MAYBE: Although a contrast-enhanced ct--or, better still, a pelvic ultrasound--are preferred methods for visualizing the ovaries, a non-contact ct would likely show nonspecific irregularities of the ovaries. Bottom line: pelvic ultrasound is the best choice for visualizing ovaries. ...Read moreSee 3 more doctor answers
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 moreSee 1 more doctor answer
Which is better for detecting ovarian tumors ultrasound or cat scan, my pelvic ultrasound said solid mass, CT said no mass?
Complimentary: Ct ; ultasound are complimentary imaging modalities. For smaller masses in appropriate location ultrasound may have an advantage especially if done transvaginally. For larger masses ct may have the advantage of not being blocked by bowel gas and being less degraded by large body habitus. More specific info in your case would be helpful. Size of mass? How was the sono done? Ct with oral and IV cont. ...Read moreSee 1 more doctor answer
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
Since I had-: -pancreatitis, l have gone thu the screening process. Amylase is high sometimes, endoscopic ultrasound, MRI with IV contrast all have been done & all is clear. Had in Jan, 2016 & now have my final MRI with IV contrast on 1 NOV 2016. That's the workup after pancreatitis, as far as screening, I would feel amylase levels. The rest R costly 4 screening ...Read more
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
I've undergone ultrasound, renal scan and CT scan. The CT scan results was 1. There is no lithiasis of hydronephrosis 2. No perirenal or periureteral.
Less radiation: There is no radiation exposure from an ultrasound, while CT has moderate radiation risk. Usually, US gives the info needed with lower cost and no radiation. ...Read more
UltraSOUND: I think you mean cardiac ultrasound (also known as echocardiography). They look at different things. Echo sees over all function, wall thickness, chamber dimensions, valves, and can measure blood flow and pressure. Ct is for detecting calcium and looking at the coronary arteries. ...Read more
depends: Acute appendicitis can be diagnosed with good accuracy by history, physical exam, ultrasound, and non-contrast ct scan of abd/pelvis. Now is some cases, where exam, history and other imaging is not diagnostic and observation of the patient with a surgeon is not possible, more sophisticated imaging, contrasted ct can help. Be well. ...Read more
Different no better: A thyroid nuclear uptake and scan is a functional test of your thyroid. It is useful in differentiating causes of thyrotoxicosis (excessive amounts of thyroid hormones in the body). A thyroid ultrasound is better to assess the anatomy of the thyroid gland and for guidance if biopsy is needed. ...Read moreSee 2 more doctor answers
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
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
