Vq Scan Preparation
Vent. perfusion scan: Perfusion ventilation scan is used to define certain lung diseases.The most common use for diagnosis of pulmonary embolism.Scanning combines ventilation scan, usually radioactive gas xenon 33, and tc99m maa (particles injected intravenously) for perfusion. Typically compares areas of deficient perfusion with areas of ventilation. Embolism usually multiple perfusion defects not ventilated. ...Read moreSee 1 more doctor answer
Ventilation: Ventilation part of study is inhaled gas such as xenon 33. Perfusion portion of study with tc99m maa is injected through peripheral vein such as arm. Volume of injection is quite small. ...Read more
Two steps procedure: A lung scintigraphy has two components. The ventilation part (v of v/q) which consists in inhalation of 99mtc-gaz or aerosols and the perfusion part ( q of v/q) which involves the intravenous injection of 99mtc-maa which are used to see the perfusion of the lungs. Usually a lung scan is performed to detect pulmonary emboli ( blood clots in the lungs) or to perform a preoperative evaluation ...Read moreSee 1 more doctor answer
Air flow: A VQ scan looks at ventilation, and perfusion(blood flow) to the lungs. In the ventilation scan, a patient will be asked to breath in either a fine mist, or a gas (xenon). The pattern on the image gives information about how well the lungs are ventilating and looks to see if there are areas which are not getting air. If the gas was used, we also get information about air trapping. ...Read moreSee 2 more doctor answers
Compare 2 studies: First part of study is usually inhaling gas isotope such as xenon 133. Several breaths are taken and imaging of inhalation, exhalation, and equilibrium are performed.Second part of study is intravenous injection of isotope tc99m maa into peripheral vein and subsequent imaging of lung perfusion in multiple projections.Mostly used for detectiong of pulmonary embolism. Vent./ perfusion scan compared. ...Read more
Not realy very: Ventilation/perfusion scan (v/q scan or lung scintigraphy), which shows that some areas of the lung are being ventilated but not perfused with blood (due to obstruction by a clot). This type of examination is used less often because of the more widespread availability of ct technology, however, it may be useful in people who have an allergy to iodinated contrast or in pregnancy. Thanks. ...Read moreSee 1 more doctor answer
Blood clots: V/q scans are most commonly used to diagnosis pulmonary emboli ( blood clots in the arteries of the lungs) . When these clots exist there is a miss/match between the ventllation of air thru your lungs and blood flow to your lungs .. When this happens you become short of oxygen/breath .. If the "miss-match" is severe enough.. This could even be fatal. ...Read moreSee 1 more doctor answer
I was diagnosed on a VQ scan with bilateral air trapping and was referred to a pulmonologist. I am only 22, and I have bad pain in my chest. Causes?
D dimer test results is high. Ultrasound normal, VQ scan normal, thigh is still swollen and painful what would be next step?
Had Vq scan they injected dye but didn't stick needle in me put little tube in my arm injected it into that what is the tube thing?
The little tube is: an IV (intravenous) catheter. Very likely a needle was used to insert it: a needle is inside the tiny plastic tube/catheter;it punctures through the skin into a vein. Then the plastic tube slides off the needle, remaining in the vein, and the needle is removed.The needle would continue to cut and damage the blood vessel if it remained in. Some IV systems sheath the needle when withdrawn for safety ...Read more
Bloods done last week shows d dimer positive, I've gone for vq scan at hospital they said fine sent me home now doc sent letter to see him I'm nervous
D-dimer: The d-dimer test is used as a screening tool to determine if someone has a possible venous thrombosis. It is not specific to venous thrombosis, however an elevated level with a compelling clinical story of a possible venous thrombosis would require further testing, and you have had a v/q scan which is negative which indicates that she did not have a pulmonary embolism. do a Doppler scan legs ...Read moreSee 1 more doctor answer
Please help docs! where will the injection take place when they insert the liquid for the lung VQ scan?
Usually arm: Ventilation part of study is inhaled gas such as xenon 33. Perfusion portion of study with tc99m maa is injected through peripheral vein such as arm. Volume of injection is quite small. ...Read more

What are the possible dangerous side effects of VQ scan on baby in pregnancy? I am 20 weeks pregnant with twins and dr recommend me to have vq scan
VQ scan...: There are 2 parts to a VQ scan: ventilation and perfusion. If there is a clot present, the scan will show that areas of the lung are being ventilated but not perfused. In other words, the clot is preventing blood flow in an area that is being ventilated. This is the classic finding for a pe in a VQ scan but not all scans are that clear-cut so additional testing is sometimes needed. ...Read moreSee 2 more doctor answers
