What is nuclear magnetic resonance spectroscopy?

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

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

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

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

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

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

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

Whats transcranial magnetic stimulation?

Treats Depression: The brain is an electric organ as much as it is a chemical one. Tms "activates" a specific part of the brain which relieves depression. It is safe and effective. It has been used to study and treat depression since the 1980s. It is given 5 days a week, 20minutes a session, for 4-6 weeks and can be very expensive. ...Read more

How are contrast ventriculography and radionuclide angiography different?

How are contrast ventriculography and radionuclide angiography different?

Ventrivculography: Both are different tests with different techniques. Contrast ventriculography is a cardiac catheterization procedures used to assess heart pumping function. Radionuclide angiography is a nujclear scan (muga scan) used to assess pumping function of the heart. Catheterization is an invasive procedure and muga scan is non-invasive procedure with minimal risk. ...Read more

What heart scan is better, CT scanner or ultra scan?

What heart scan is better, CT scanner or ultra scan?

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

Can nuclear medicine procedures affect CT scans?

Can nuclear medicine procedures affect CT scans?

Not usually: Not usually nuclear medicine affecting ct but the opposite. However ct scan with intravenous iodine contrast materials can affect thyroid scans and thyroid uptake. Renal GFR studies using glofil with i125 are also affected by iodine contrast of ct. ...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
