What Is The Difference Between Aortography And Angiography
encompasses several medical imaging tests that visualize the anatomy and pathology of blood vessels. Standard angiography involves catheterizing a vessel and injecting contrast under X-ray visualization. Less invasive angiographic techniques include MR angiography ...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
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
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
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
Location: Surface echocardiogram-the ultrasound transducer is on the chest wall. In transesophageal echocardiogram, the transducer is placed down into the esophagus, much like an endoscopy. The imaging is clearer with transesophageal echo which helps when looking for prosthetic valves, clots or infected valves. ...Read more
Drugs for Heart Test: Chemical stress tests are used to diagnose heart artery blockage in people who cannot treadmill exercise. Persantine is injected IV and dilates normal blood vessels more than abnormal ones causing an ischemic defect on a nuclear image. Dobutamine is injected IV and increases the heart rate and contractility with muscle fed by a blocked artery not responding as well as normal muscle. ...Read moreSee 1 more doctor answer
Cause and effect: Atherosclerosis is a process where plaque builds up in arteries due to a variety of factors. When the plaque build up is extensive enough it can restrict blood flow and cause ischemia. Ischemia, which occurs when blood flow is not sufficient to meet the need for blood may result from extensive atherosclerosis. however it is important to note that atherosclerosis usually does not result in ischemia ...Read more
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
