Vq Scan Preparation
Had vq scan for possible PE came back grossly normal one slice could not be seen clearly. What does grossly normal mean?
It means that you: Do not have a pulmonary embolismGet a more detailed answer ›
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 more
See below: The ventilation part of the v/q scan will show air trapping which may be patchy. The perfusion is usually not affected much but bottom line is the v/q scan will be more difficult to read and the results may be inconclusive. ...Read more
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 more
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 more
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 more
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 more
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 more
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
VQ cancer: Highly unlikely to occurGet a more detailed answer ›
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: A VQ scan is generally done evaluating for a pulmonary embolism - -a very serious medical condition. A VQ scan is low risk procedure and typically needs to be done urgently if a pulmonary embolism is suspected. ...Read more
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 more
How can u possibly have a VQ scan 75+ prob PE, all symptoms, high d-dimmer and Ct 2 months later say no? PFT good, No lung disease, low DLCO 50%?
Lucky: U are that u fall in normal when PE resolves in 2 to 28 days. So don't be suprized be happy. ...Read more

31 m - Is a bronchoscopy / chest Ct scan with contrast and Vq scan good enough to rule out lung cancer or lung problems?
2011 clean cardiac cath, vq scan, echo, ekgs. Since then I have done a lot of tests 2 days ago an echo stress test normal. Jaw pain when run heart?
If I tested borderline positive on blood test for lung blood clots but negative on VQ Scan is it possible a CT Scan or another test could be positive?
Normal chest X-ray and VQ SCAN. Normal ekg. Chest and back pain, gurggling sound, short of breath, dizzy. Also tachycardic and dry cough. Please help.
In-Person Evaluation: You need further face2face evaluation by a physician. Sounds like you are in the middle of a work-up. Are you an inpatient or is this evaluation being done as an outpatient? Sounds like you are looking for a second opinion? Too much information is required to properly second guess your current work-up. Online is not appropriate for this purpose. ...Read more

Zoloft is safe.: If your tests are all normal, then you may be suffering from physical symptoms of anxiety. Some people are sensitive to sensations in their body, and others think they may have dread diseases. Zoloft is a safe med for your symptoms. In the elderly and persons on blood thinners or who have osteoporosis, Zoloft should be used with care and monitored more closely. ...Read more
Lab: Most commonly the undercuts, if there are any, are blocked out in the lab. Occasionally the lab will make a index/guide for the dentist to use to modify the shape of the tooth before delivery of the crown. Before or during the preparation for a crown, a dentist may use any number of materials to block out undercuts. ...Read more
Nothing specific: Eat well 1-2 d prior (red meat and/or dark leafy greens good choices), hydrate well shortly before donation appointment. Continue to hydrate and eat well for 1-2 d after. Return cycle feels a little cool, other than that and using pheresis machine, not too much different feeling than 'regular' donation. Thanks!! ...Read more
