What Is The Difference Between Hida And Pipida
Patient is injected intravenously with isotope tagged to chemical hida that is extracted preferentially by liver cells mimicking bile. Some of this is stored in gall bladder and some enters small bowel from common bile duct. Cholecystokinin is a natural hormone slowly injected intravenously to stimulate gall bladder contraction. Normal function has at least 50% ...Read more
Different organs: Different conditions. Kidney stones of calcium & can be treated with shockwave treatment or could pass on their own. Gallstones from bilurubin or cholesterol & needs gallbladder surgery if causing upper abdominal pains. Both can be observed if causing no symptoms. ...Read moreSee 1 more doctor answer
Different organs: Pancreas is an organ behind the stomach & has 2 main functions - releases enzymes into the small intestine for digestion & releases Insulin into the blood stream for blood sugar management. Gallbladder is under the liver, connected to the bile duct & squeezes extra bile into the small intestine for digestion. Can easily live without a gallbladder, not so with the very important pancreas. ...Read more
Lung vs gi tract: Bronchoscopy is the study where they look into your lungs with a bronchoscope. Endocopy, a non-specific term, usually refers to the procedure of looking into your GI tract (stomach, intestines). But, in general, endoscopy is any study that looks inside your body, so a bronchoscopy is a type of an endoscopy... ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Contrast: An xray (also called radiograph) is done by sending xrays through a body part but only in one projection so there is overlap of body parts and contrast is not very good. Ct also uses xrays but the final cross-sectional image (slice) is reconstructed from a combination of xrays shot from multiple directions/projections; therefore, there is no overlap of body parts and much better contrast. ...Read more
Verb versus noun: Angiography is the process of performing an x-ray picture (or an image) of a blood vessel by injecting the vessel with an opaque dye. Th dye often contains iodine. An angiogram is the picture of the blood vessel that was taken while performing angiography. ...Read moreSee 1 more doctor answer
Here are some...: These 2 terms have been used to describe the blood circulation into/through the kidneys. Hemoperfusion denotes blood flow into kidneys through big renal ateries and hemofiltration denotes blood flow further circulating to smaller arterioles into/through glomeruli (microfilters) and onwards where the wanted and unwanted wastes exchanged so to adjust water and electrolyte balance and others. ...Read more
Pancreas and spleen: The pancreas is a complex organ with several functions. 85% of your food is digested by enzmes produced by the pancreas, glucose regulations is also related to cells in the pancreas. The spleen is a part of the immune system that stores lymphocytes and helps get rid of old red blood cells. It is important in platelet destruction and is a blood regulator as well as acts as a large lymph node. ...Read more
A lot: Aneurysm the entire three layers of the blood vessel has enlarged to a substantial degree usually 2-2.5 times normal size- called dilation of the entire blood vessel. Veins can become aneurysmal also. Vasodilation is a term for capillary dilation and low peripheral resistance and has nothing to do with aneurysm. A fluke of the english language. ...Read moreSee 1 more doctor answer
Dyscalculia = " to : count badly", from its Greek & Latin root words. Deficits in information processing, memory & retrieval in an infant or child who lacks age-appropriate intuitive understanding of numerical concepts cause developmental dyscalculia. Acalculia is acquired & of late onset. It is caused by anything that damages areas of the brain involved in mathematical operations. Acalculia = unable to count. ...Read more
I have had 2 hida scans 6 weeks apart. The 1st failed to visualize the gb after 4 hrs, the 2nd with cck = 53% ef. No narcotics, etc. Why difference?
Sometimes: Hida scans are usually ordered for 2 reasons: to see if the gallbladder is obstructed, or (when combined with cck) to check gallbladder function. Hida is painless but the cck injection may reproduce a gallbladder attack. This information is very useful since, if your pain is reproduced, it suggests that your pain is arising from the gallbladder. ...Read moreSee 3 more doctor answers
See below: A radioactive tracer is injected into your veins. This is taken up by the liver and excreted in bile. It can then be followed using a camera to see that it empties into your intestine. If you have a gallbladder one can see if it functions properly too. ...Read moreSee 2 more doctor answers
Yes, but not common: Yes, just about any study can have false positives, however it is not common with a hida scan. Things which can interfere with the study and cause a false positive include, prolonged fasting(more than 24hrs), very poor liver function, non-fasting state (less than 4hrs), prior surgery to remove the gallbladder, pancreatitis, TPN (total parenteral nutrition). ...Read moreSee 3 more doctor answers
One/ two phase exam: Hida scan is usually two part examination.First phase intravenous injection of isotope with technetium accumulating in liver, excreted like bile into bile ducts, accumulating in gall bladder, and excreted into bowel.Second phase slow intravenous injection of cck, hormone, causing gb contraction determing gb ejection fraction.Sometimes discomfort mimicing abdominal symptoms.Looking for gb disease, ...Read more
HIDA scan is easy: Hida scan is a common test by nuclear medicine. Hida is injected into blood, then is taken up by your liver & excreted into the bile ducts. If your gallbladder functions (is not sick), it will "light up" when it concentrates the hida material. Giving cck then allows measurement of gallbladder emptying time, patency of the bile ducts, & how effectively the hida material enters your small bowel. ...Read moreSee 2 more doctor answers
Ejection fraction: The ejection fraction is the portion of the gallbladder contents that are expressed from the gallbladder with contraction. Normally the gallbladder has an ejection fraction greater than 35%. An EF of 8% may indicate abnormal gallbladder function, and it needs to be considered along with the clinical situation to determine if a cholecystectomy should be performed. Good luck. ...Read moreSee 1 more doctor answer
Not usually: Most people dont feel any better..Or worse after a hida scan. It is rare to have an adverse (or bad) reaction. It usually does not make one feel better, however if they used morphine during the study..It would be possible to feel the effects of that. ...Read moreSee 2 more doctor answers
HIDA scan: You'll change into a gown and will lay on the nuclear medicine scanner bed. A medication (radioactive tracer) is then injected into a vein in your arm (you may feel some pressure). The gamma camera passes back and forth over your belly and takes pictures for about an hour. Sometimes, more pictures may be needed. In most cases you can go about your day after your hida scan. ...Read moreSee 1 more doctor answer
False positives: Variability in results depends on method of test, interpretative skills, patient symptoms. It is not perfect.If gb ejection fraction is low in patient with biliary colic , chronic gall bladder disease /biliary dyskinesia probable. With acute symptoms non visualization of gb means acute cholecystitis, surgical emergency. False positives prolonged fasting, tpn, alcoholism, recent narcotic, pancreatitis. ...Read moreSee 1 more doctor answer
Up or down: It is really depend if the numbers are going down mean your gallbladder function getting worst if is up and down the test is not reliable and depend on your symptoms if the fluctuation up and down but still below 30% your gallbladder could be the problem. ...Read moreSee 1 more doctor answer
