Ct Scan With Contrast Vs Mri
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
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
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
What's difference between High HD Contrast CT scan vs Normal Chest CT with contrast evaluating interstitial lung markings?
Different chest CTs: High resolution chest CT usually with out intravenous contrast is used to define interstitial lung disease pattern, whether diffuse or localized process. CT of chest examination with contrast intravenously usually looking for tumors or metastases and acute infection in the lungs. ...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
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
Whats better for diagnosing pancreatic cancer.... Ct scan or mri? I've had normal ultrasound and CT scan with contrast. Still worried.
Differences: The ct scan uses radiation from multiple x-ray devices to see internal organs. The MRI uses very strong magnetism to orient the body's water molecules and see internal structures such as ligaments, joints, brain, etc. Each study has its own individual benefits or indications. ...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
Looking at bone: The CT scan is better than MRI in detecting bone fractures or pathologies involving the bone. MRI is better at distinguishing between soft tissues. CT scan is also faster & quieter than MRI. However, the CT scan uses radiation & there has been an explosion of radiation-related conditions in recent years. Each modality measures different things. So ask your doctor if the test is needed or not. GL. ...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
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
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
Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more
