Liver (Definition)

This organ plays a major role in metabolism and has a number of functions in the body, including glycogen storage, decomposition of red blood cells, plasma protein synthesis, hormone production, and detoxification. It lies below the diaphragm in the abdominal-pelvic region of the abdomen. It produces bile, an alkaline compound which aids in digestion via the emulsification of ...Read more

What can a cat scan of the liver be used to diagnose?

What can a cat scan of the liver be used to diagnose?

CAT scan of liver: Cat scans take numerous xray "slices" of the liver, gall bladder and the surrounding tissue. Many diseases of these structures can be discovered, however many diseases do not show up on cat scans. Cat scans are images and they must be interpreted by physicians who specialize in this. ...Read more

What is the purpose of CT scan and is it the best diagnostic procedure for cva?

What is the purpose of CT scan and is it the best diagnostic procedure for cva?

Helical Xray: A ct(computed tomography) scan is a helical xray exam to look inside a body. It is fast, but lacks the fine detail seen in an MRI (magnetic resonance imaging) scan, which makes it a superior exam for a cva (cerebral-vascular accident or stroke). ...Read more

Is there a lot of radiation associated with a CT scan with contrast for the renal area? Can the contrast cause an allergic reaction?

Is there a lot of radiation associated with a CT scan with contrast for the renal area? Can the contrast cause an allergic reaction?

No: CT of abdomen is a fairly routine test and not considered a radiation danger. Th incidence of allergic reaction to contrast is 1-3% with non-ionic agents and 4-12% with ionic contrast agents.Non-contrast agents are the type generally used today. The benefit from the diagnostic value of the test far exceeds the risk of these 2 issues. Hope this answers your question. ...Read more

When is a CT scan of the neck used?

When is a CT scan of the neck used?

Good test: Can look at bones for fracture if you had trauma. Can do cta neck to look at blood vessels if you have carotid artery disease. Can look at tissues to see if there is a cancer or infection. These are a very few examples of the uses of ct. See radiologyinfo.Org. ...Read more

What is a cat scan of the brain used for?

What is a cat scan of the brain used for?

Fast brain study: Cat scanning is used often to check for acute brain problems such as tumors, bleeding, skull fractures, sinus infections, looking for larger obvious pathology to make a rapid determination of the need for immediate intervention, and provides better views of bone and sinuses than MRI (which is better to see strokes or ms lesions). ...Read more

What is a pet scan used for?

What is a pet scan used for?

Approved for cancer: Pet scan are approved for staging, response assessment and surveillance of certain types of cancers. However, any pathologic process that augments the consumption of glucose (such as infection or inflammation) can be evaluated, though these indications are not currently covered. In addition, pet scans are used to evaluate for brain cognitive disorder, heart ischemia and myocardial viability. ...Read more

The dye which is used for MRI is made up of what?Does it contain any radioactive substance?

The dye which is used for MRI is made up of what?Does it contain any radioactive substance?

No: There are about 7-8 marketed MRI contrasts in the us. The safest ones do not cause nsf. These are multihance, ProHance and eovist. None of these have been associated with nsf when used alone. Nsf is a skin condition which is extremely painful. It usually happens to people with poor renal function. So.. You should tell your doctor if you have poor kidney function. ...Read more

My CT scan result is mild cortical atrophy what is the best medicine and treatment for this case?

My CT scan result is mild cortical atrophy what is the best medicine and treatment for this case?

Live Healthy: If you are hypertensive, make sure it is well controlled. If you are diabetic, keep it well controlled. Don't smoke! smoking accelerates atherosclerotic changes of the arteries all over the body, including the brain. So does diabetes. The combination is worse than the sum of the parts. More than 2 drinks a day could also be deleterious to the brain. ...Read more

What is the difference between an MRI and a cat scan? Except for the radiation factor.

What is the difference between an MRI and  a cat scan? Except for the radiation factor.

Physics: The physical phenomena on which these imaging techniques are built are very different, each is best suited for different purposes. Cat scans are sophisticated x ray, they rely on the degree of absorption of gamma rays (bones, ca, other metals will contrast most). Mri is better for softer tissue imaging because it depends more on the behavior of hydrogen atoms and h2o in the strong magnetic field. ...Read more

What is a pet scan? What is a pet scan and how is it different from other breast imaging procedures?

Anatomy vs Physiolog: Mri and ct look at the structure of the body, the anatomy, and the way diseases change or distort it. Pet looks at the physiology, or how the body uses, or metabolizes something. For pet, the most common metabolism pathway looked at is how glucose is used. Ct is used to correlate anatomy to the pet pet images the whole body, while mri, us and mammography are limited to a portion of the body. ...Read more

What are the effects of an MRI with contrast? Exactly how bad is the contrast and what is it made of? Is it safe for people with hypothyroidism?

What are the effects of an MRI with contrast? Exactly how bad is the contrast and what is it made of? Is it safe for people with hypothyroidism?

Generally safe...: The contrast used for an MRI (gadolinium) is considered generally safe for administering to most people (including hypothyroidism). It's a metallic salt excreted by the kidneys. The only major concern...In patients who have renal failure/insufficiency, care should be taken to avoid a condition known as nsf. Sometimes the MRI contrast is confused with ct contrast which has many more complicatioons. ...Read more

What is the difference in diagnostics between mri, cat scan and colonoscopy? Which one is best for identifying problems?

What is the difference in diagnostics between mri, cat scan and colonoscopy?  Which one is best for identifying problems?

Depends: Mri and ct scans are noninvasive imaging techniques. They have their own inherent advantages and disadvantages, and to compare them would be too complicated here. Colonoscopy is invasive, where a camera is extended via the rectum into the colon to see what the inside of the colon looks like, usually for cancer screening. ...Read more

When is a mr spectroscopy used and what conditions is it mainly used to diagnose?

When is a mr spectroscopy used and what conditions is it mainly used to diagnose?

MR spectroscopy: allows tissue to be interrogated for the presence and concentration of various metabolites. It often doesn't add much, but can be useful in the evaluation of brain tumors, radiation effects, ischemia/infarction, brain infection, and certain white matter diseases. ...Read more
