When do they need a CT or MRI to detect ivh?

When do they need a CT or MRI to detect ivh?

For a term, rarely: If a term or a late preterm infant is stable enough to be transported to ct or MRI area, and less than 4 days old, ct is preferred. Otherwise MRI is the best. They are recommended if the infant has seizures, extreme lethargy or irritability, recurrent apnea (forget to breath), evidence of trauma (like head injury from forceps or vacuum delivery), suspected shaken baby syndrome, CNS infections etc. ...Read more

Computed Tomography (Definition)

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

How does an MRI differ from a ct?

How does an MRI differ from a ct?

See below: I agree with the above answer but would like to add that in a way MRI is a way to look into the body at a molecular/atomic level, studying how the hydrogen atoms behave in your body and thus help in the diagnosis of your condition. There are other atoms can can be study (such as sodium) but hydrogen base MRI technique is most common. ...Read more

What can an MRI show that a CT can't?

What can an MRI show that a CT can't?

It depends: Both are very good at imaging various parts of the body. Depending on the body part and the question being asked, ct or MRI may be better. In general, MRI can "see" the soft tissues a little better (e.g., brain and spinal cord, rotator cuff) and ct is sometimes better for looking at the bones (e.g., facial fractures, sinuses). Doctors work closely with radiologists to determine the best test. ...Read more

What is the difference between an MRI and a ct?

What is the difference between an MRI and a ct?

MRI/CT: A CT scan uses x-ray radiation to generate an image. An MRI uses magnetic fields "tuned" to the frequency of protons in the body. Since each scan essentially measures a different property of tissues in the body, they are complementary tests. That is why if one doesn't provide a definitive answer, often the other will be ordered. ...Read more

Can you please tell me how MRI and CT scans differ?

Can you please tell me how MRI and CT scans differ?

Radiation: The links that dr. Janjua listed are excellent. But the simple answer to your question is: ct scans depend on radiation to generate their images. Mri scans use magnetic waves to activate the protons which then give off characteristic signals that produce the images. The bottom line-no radiation with mris. Mris are better for soft tissue differentiations (ie. Brain tumors), ct are better for bone. ...Read more

Cts versus mris? What is the difference between a CT and a mri?

Cts versus mris? What is the difference between a CT and a mri?

Different technology: Ct uses ionizing radiation, like xray, to produce images of the inside of your body. Mri uses a very powerful magnet to produce similar images. Each technology has it's strengths. For example, MRI is better at detecting stroke, while ct is better at detecting appendicitis. ...Read more

Would an MRI or CT show something the size of a pinhead, about 2mm?

Would an MRI or CT show something the size of a pinhead, about 2mm?

Close, if there is: Enough contrast with adjacent structures. Radiologists (physicians with 5 or more years of additional training after medical school) routinely identify pulmonary nodules in the lung down to 2 millimeters, and 1 mm nodules can sometimes be identified. Certainly, 3 mm nodules are clearly seen at both ct and MRI in many organs, if different in appearance from the surrounding tissue. ...Read more

What is the major difference between CT and MRI technology? How are the results different?

CT : Ct and MRI are complementary exams in many cases, which means that we can examine the same body area and get different "looks" to help us figure out what we are seeing. Ct uses ionizing radiation, while MRI uses magnetic fields to create images. (a physicist once reminded me that a magnetic field is also radiation, but the kind that people talk so much about, in relation to cancer potential, is the ionizing type.) example: when a kidney or liver mass is seen at ct, a radiologist might suggest that an MRI could help to further clarify (1) whether it is real, or (2) what it is. We don't always need an MRI to clarify a ct finding, just sometimes. That "sometimes" is determined by the radiologist, depending on how the abnormality looks at ct. ...Read more

Are there times when both CT and MRI procedures may be necessary? What are the main differences, and is one more risky than the others?

Yes: There are times when both are used. CT uses xrays to make the images, MRI uses both magnetic waves and radio waves. Both have sensitivities that make them good for certain things and worse for others. We often get both because they tell different things. Since CT uses x-rays we try to keep that in mind so that we don't irradiate people needlessly. CT scans can theoretically increase cancer risks. ...Read more

Mri (Definition)

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
