Causes Of Altered Tissue Perfusion
Shouldn't: A myocardial perfusion scan shouldn't cause a cough. Perhaps a mild allergy is present but this is extremely rare. A ventilation-perfusion scan may cause a cough primarily due to the ventilation scan component. People who get these tests often have underlying medical problems associated with cough, and that would be the primary reason for the cough, not the scan.See 1 more doctor answer
The body is composed of tissue that are classically described as beiing derived from three basic embyonic layers known as the endoderm, mesoderm and ectoderm that then differentiate into the structures that compose the body such as skin, soft tissues, bone, muscle, organs, etc. Stem cells are not differentiated and have the potential to ...Read more
Many methods...: Depending on which tissue you are talking about, there are many ways. Brain perfusion is reflected in level of consciousness. Kidney perfusion is assessed by adequacy of urine production and laboratory tests. Perfusion of the extremities can be assessed by skin color and tone as well as radiologic tests and angiography and other laboratory tests.See 1 more doctor answer
Would a low diastolic at exercise cause lower coronary perfusion? Say 120/50 or 120/40? Comparing to 120/80 etc?
No: Coronary blood flow depends on the caliber of the blood vessels as well as the pressure. This is a good BP for anyone. How you feel is important too.
What's the care plan for patient with nephrotic syndrome and diagnosed with ineffective tissue perfusion, renal?
Depends: It depends on if it is steroid responsive or not. Treatment can vary - it needs to be individualized.
Cerebral perfusion: Nothing is 'supposed' to cause poor cerebral perfusion. When cardiac function becomes poor enough to decrease cardiac output and or blood pressure enough to perfuse the brain adequately, then the patient is in serious trouble. This usually happens only with severe cardiac dysfunction and often has associated cerebral vascular disease.
I accidently spent 30 minutes with a patient during a myocardial perfusion scan while I am 3 weeks pregnant. Will it cause problems for my baby?
No: I work in a cardiac cath lab and my nurse was pregnanat and wore a badge outside her lead apron. It received essentially zero radiation despite hours and hours of exposure. The key is the inverse square law. The radiation drops off very quickly as you move inches away from the source (the patient's bloodstream). You have had a negligible exposure - you get more on a sunny day!See 2 more doctor answers
What does this mean: myocardial perfusion imaging adversely affected by soft breast tissue attenuation?
Imaging Artifact: Soft tissue attenuation in the breast is a common artifact in myocardial perfusion imaging. It may artifactually affect the depiction of activity in the myocardial wall. If perfusion defect is seen on both stress & rest images and normal wall motion & wall thickness shown on ecg-gated spect then apparent fixed defect is an artifact of attenuation instead of an area of myocardial infarction.
Blood flow.: Perfusion usually refers to blood flow into an organ or organ system.See 1 more doctor answer
Prior heart attack: This represents either evidence of a prior heart attack or an area of the heart receiving very poor blood flow from a blocked artery.
Please explain this statement: moderately reduced perfusion in the inferior wall w/notable but incomplete reversibility.
Blocked artery: It means you may have had a heart attack to the bottom part of the heart. Some of it is scar and some is viable.
Need both: Not sure what you are referring to regarding perfusion being more important than ventilation. In regards to a lung perfusion ventilation scan, a mismatch between perfusion and ventilation is abnormal and can suggest pulmonary disease. Ventilation delivers oxygen to the blood via the lungs, then perfusion (blood) delivers the oxygen to the body, so both are important.See 1 more doctor answer

MRI Perfusion: Perfusion MRI is an advanced MRI technique which shows whether blood flow to regions of the brain is normal or abnormal. In the picture above, in the right upper part of the image, there is a dark area showing an area of brain stroke in the frontal lobe. The technique requires injection of gadolinium contrast through an IV. In addition to stroke, it can also be used to diagnose tumors or infection
Blood clots in lungs: It's a nuclear test to look for blood clots in the lungs. It has been largely replaced with high resolution spiral ct scans.
Let me try to: Myocardial perfusion scan is a nuclear medicine procedure that illustrates the function of the heart muscle (myocardium). It evaluates many heart conditions from coronary artery disease to hypertrophic cardiomyopathy and myocardial wall motion abnormalities. The function of the myocardium is also evaluated by calculating the left ventricular ejection fraction (lvef) of the heart. Good luck.See 3 more doctor answers
Stress Test: That uses a radioactive tracer to evaluate blood flow in the coronary arteries. Images are taken at peak exercise and at rest. These images are able to compare blood flow to the heart in specific territories supplied by each coronary artery and any flow disparity would be consistent with a potential blockage in that artery.
Dx Pulmonary Embolus: A ventillation perfusion lung scan is a nuclear test used to diagnose a blood clot to the lung or pulmonary embolus. Medication is injected into your vein and you also breath a medication into the lung to look for a mismatch on a nuclear imaging camera which would suggest a pulmonary embolus.See 1 more doctor answer
