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

What are advantages of MRT (Magnetic Resonance Tomography) scan over MRI (Magnetic Resonance Imaging) scan? Are these equally safe?

What are advantages of MRT (Magnetic Resonance Tomography) scan over MRI (Magnetic Resonance Imaging) scan? Are these equally safe?

Same: Those are equivalent terms for the same type of imaging. No x-rays or iodine containing contrast is used for MRI studies. Here is a helpful link. http://www.mr-tip.com/serv1.php?type=db1&dbs=Magnetic%20Resonance%20Tomography ...Read more

Any good uses of cat scan and magnetic resonance in dentistry?

Any good uses of cat scan and magnetic resonance in dentistry?

Yes and increasing: The increased availability of advanced imaging techniques are useful in accurately locating impacted teeth, diagnosing pathology, locating vital structures for implant placement and tooth removal, to diagnose fractures and facial malformations and in general allow the dentist to accurately see that which is unseen. ...Read more

Is Magnetic Resonance Venography better than a CT Venography?

Is Magnetic Resonance Venography better than a CT Venography?

YES: Yes MRI is usually more accurate than Ct venogram.However certain situations like CT angiography of the brain is usually better a radiologist or specialized physician needs to decide case-by-case if MRR CT is better ...Read more

Does a magnetic resonance venogram have superior image quality to a CT venogram?

Does a magnetic resonance venogram have superior image quality to a CT venogram?

No, CT spacial image: detail quality (partially older technology with more improvements over time) remains much superior to MRI. Yet CT is radiation, MRI (actually NMRI) no radiation, but slower, more noise & better at distinguishing soft tissue differences. Yet both only show location of dye in vein, not the vein itself, thus can easily miss issues present but not reflected in dye column. ...Read more

What is nuclear magnetic resonance spectroscopy?

MRS or MRI: MRI is magnetic resonance imaging a type of medical imaging MRS is MR spectroscopy a rarer medical type of exam based on the science behind MRIs in part aimed at either parts of the brain or perhaps skeletal muscle to evaluate metabolism at times....both would be done in an MRI facility. when developed the nuclear part of both was dropped so as to not scare people about it.... ...Read more

Can a high-powered magnetic resonance imaging scanner cause cancer to patients or staff?

Can a high-powered magnetic resonance imaging scanner cause cancer to patients or staff?

No known association: Mri relies on changing nuclear atomic spin, and does not change the chemical bonds of molecules, which can alter dna and cause cancer. However, the use of a contrast agent in patients called gadolinium during the procedure may induce the onset of a debilitating malady commonly known as nsf/nfd. This can cause fibrosing throughout the body. http://www.medscape.com/viewarticle/550783. ...Read more

Is magnetic resonance venography without contrast as accurate as mrv w/ contrast? Is mrv good accurate for distal clots?

Is magnetic resonance venography without contrast as accurate as mrv w/ contrast? Is mrv good accurate for distal clots?

MRV advantages: "Contrast media-enhanced MRV, however, is more reproducible and less susceptible to artifacts." "...MRV to have both high sensitivity (range, 87.5%–94.5%; pooled sensitivity, 92%) and specificity (range, 92.6%–96.5%; pooled sensitivity, 95%)" http://www.guideline.gov/content.aspx?id=47686 Advantages: deep calf, abdominal, and pelvic vein imaging. can show source of compression ie. source. ...Read more

How accurate are contrast cat scan in detecting non ruptured annreuysms brain?

How accurate are contrast cat scan in detecting non ruptured annreuysms brain?

Aneurysms: Compared with the number of aneurysms detected on dsa, the overall accuracy rates of cta and mra for aneurysm detection were 89% and 90%, respectively. 4 the sensitivity for aneurysms 3 mm was 96% for cta and 94% for mra. ...Read more

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Ct scan, mri, nuclear medicine imaging, ivp scan, how are they different?

Quite different: Ct involves xray type radiation with cross sectional imaging in transaxial, sagittal, and coronal projections. Nuclear medicine, internal irradiation either injected intravenously, inhaled, ingested, injected subcutaneously.Ivp uses injection of contrast material for visualization of kidneys and bladder with x-ray. Mr imaging uses no ionizing radiation magnetic fields to generate x-sectional images. ...Read more

Can magnetic resonance imaging be done on persons with metal implants in their body?

Can magnetic resonance imaging be done on persons with metal implants in their body?

It depends: Mri scans place the body in a magnetic field. A metal fragment in the eye may move and create damage to the eye. A hip or knee prosthesis is unlikley to be affected but may create imaging problems because they will distort the magnetic field and the image created. ...Read more

Mri(magnetic resonance imaging ) ok if stainless steel plate in arm?

Mri(magnetic resonance imaging ) ok if stainless steel plate in arm?

Yes, but..: A stainless steel plate for fracture repair will affect imaging of that specific area. Some people can have sensations when getting the exam but most don't. Effects may be more significant on the stronger 3t magnets but most people notice little to nothing. ...Read more

Expert opinions? Which modality exposes patient generally to more radiation, bone scan or computed tomography?

Expert opinions? Which modality exposes patient generally to more radiation, bone scan or computed tomography?

Sometimes same dose: Background radiation at sea level: 3 msv per year, denver residents get: 6 msv per year, cross country flight: 0.02 msv, x ray chest: 0.06 msv, ct head: 3 msv, ct chest: 5 msv (equivalent to 100 chest xrays) ct abdomen: 5-10, average bone scan 6.5 msv. Radiation depends on size of patient." radiation affects growing body in children more than adults. Doses to children are much less. ...Read more
