Steps to take before the procedure
When the patient comes for the lung V/Q scan, he/she is requested to bring the doctor’s prescription and any previous scan (CT, MRI, USG, X-ray, PET-CT) reports along. The patient may be asked to remove any metal objects, such as a belt or jewellery, or other objects that may interfere with image results. The patient may be asked to eat or drink normally as usual.
What happens during the Scan?
The radioactive material (radionuclide) is inserted in the arm or hand through an IV (intravenous) line, or with an injection in case of a perfusion lung scan. While the procedure is going on, the camera will start taking some images of the lungs. The patient will be asked to inhale a gas that contains radioactive substance through a face mask in a ventilation lung scan. The patient will have to hold the breath for a certain amount of time, after inhaling the gas. While the patient is holding the breath, the scanner will start taking images of the lungs. The scanner will continue to take images while the patient breathes in the radionuclide for a few more minutes. The face mask will be removed after the radionuclide gas has built up in the patient’s lungs.
After the procedure
The nuclear medicine specialists will process and review the scans and issue a written report. This usually takes a day. The patient can expect the results within 24 hours of the examination. The referring doctor will discuss the results with the patient. He/she can collect the reports from Medanta’s Nuclear Medicine/PET-CT report collecting desk.
