The person who does the scan cannot give the results.</li> </ul><h2>How long does the scan take?</h2> <p>The lung perfusion scan on its own takes 15 to 20 minutes. The two scans take 45 to 60 minutes in total.</p><h2>Will I be able to stay with my child during the scan?</h2> <p>One parent or guardian may stay in the room during the scan, but no other children are allowed.</p> <h2>How are the scans done?</h2> <p>Some children only have a lung perfusion scan, but others have scans for lung perfusion and ventilation. Each scan is done by a nuclear medicine technologist.</p> <p>If your child is having both scans, the ventilation scan happens first.</p> <h3>Lung ventilation scan</h3> <p>For this scan, your child will be given a mask or mouthpiece and asked to breathe in and out a tiny amount of radioactive mist for about five minutes.</p> <p>The technologist will then remove the mask or mouthpiece and use a special camera to take pictures of your child's lungs.</p> <h3>Lung perfusion scan</h3> <p>Your child will first be given a small needle (injection) into a vein in their arm or the back of their hand. The injection contains a very small amount of radioactive medicine that mixes with the blood and will go to the lungs.</p> <p>Your child will then lie down on a narrow table with a safety belt across their stomach to keep them safely in place while a special camera takes pictures of their lungs. In most cases they can watch a movie as the scan is being done.</p> <p>Note: The injection before the lung perfusion scan is not painful, but your child's hand or arm can still be numbed first with a topical anaesthetic (a special cream or cooling spray). If you would like this option, it is best to arrive at least 30 minutes before your appointment to allow the anaesthetic to take effect.</p><h2>Does my child need to do anything special to prepare for the scan?</h2> <p>No, your child can eat and drink as usual.</p><h2>At SickKids</h2> <p>If you have any questions or concerns about the scan or if you need to change your appointment, please call the Nuclear Medicine Department at 416-813-6065.</p><h2>Source</h2> <p>Alliance for Radiation Safety in Pediatric Imaging (2013). <a href="http://www.imagegently.org/Roles-What-can-I-do/Parent/Nuclear-Medicine" target="_blank"><em>Image Gently: Nuclear Medicine - What can I do as a parent?</em></a></p>

La scintigraphie pulmonaire de ventilation vise à déterminer si l’air et le sang circulent bien dans toutes les parties des poumons.</li> <li>Pour la scintigraphie pulmonaire de ventilation, votre enfant devra inspirer et expirer une quantité minuscule de vapeur radioactive pendant cinq minutes avant qu’une caméra spéciale prenne des clichés de ses poumons.</li> <li>Pour la scintigraphie pulmonaire de perfusion, une minuscule quantité d’un radiopharmaceutique (substance radioactive pharmaceutique) sera injectée dans le sang de votre enfant, puis des clichés des poumons seront pris pour déterminer si la substance s’y rend correctement.</li> <li>Un médecin de l’équipe de médecine nucléaire fera parvenir les résultats à votre médecin de famille ou à votre pédiatre (médecin pour les enfants) dans les deux jours ouvrables suivant l’examen. Le technologue qui effectue l’examen ne peut pas vous transmettre les résultats.</li> </ul><h2>Combien de temps l’examen dure-t-il?</h2> <p>La scintigraphie pulmonaire de perfusion seulement dure de 15 à 20 minutes. Les deux scintigraphies combinées durent de 45 à 60 minutes.</p><h2>Pourrai-je rester auprès de mon enfant pendant l’examen?</h2> <p>Un parent ou une personne qui a la charge de l’enfant peut demeurer dans la pièce durant l’examen, mais aucun autre enfant n’y sera admis.</p> <h2>Comment se déroulent ces scintigraphies?</h2> <p>Certains enfants ne passent que la scintigraphie pulmonaire de perfusion tandis que d’autres subissent à la fois des scintigraphies pulmonaires de perfusion et de ventilation. Chacune des scintigraphies est effectuée par un technologue en médecine nucléaire.</p> <p>Si votre enfant doit passer les deux types de scintigraphies, il subira d’abord la scintigraphie de ventilation.​</p> <h3>Scintigraphie pulmonaire de ventilation</h3> <p>Pour cet examen, on donnera à votre enfant un masque ou un embout buccal, et on lui demandera d’inspirer et d’expirer une vapeur radioactive pendant cinq minutes environ.</p> <p>Le technologue retirera alors le masque ou l’embout buccal et, à l’aide d’une caméra spéciale, réalisera des clichés des poumons de votre enfant.​</p> <h3>Scintigraphie pulmonaire de perfusion</h3> <p>On fera d’abord une petite injection (piqûre) dans une veine du bras ou au dos de la main de votre enfant. L’injection contient une très petite quantité d’un radiopharmaceutique (substance radioactive pharmaceutique) qui se mélangera au sang de votre enfant et sera acheminée vers ses poumons.</p> <p>À ce moment, votre enfant s’allongera sur une table étroite, et une courroie de sécurité lui sera fixée sur l’estomac pour bien l’immobiliser pendant que le technologue prendra des clichés de ses poumons à l’aide de la caméra spéciale. Les enfants peuvent habituellement regarder un film durant l’examen. </p> <p>Nota : L’injection administrée avant la scintigraphie pulmonaire de perfusion n’est pas douloureuse, mais on pourrait quand même engourdir le bras ou la main de votre enfant à l’aide d’un anesthésique topique (par application d’une crème spéciale ou par vaporisation d’un produit de refroidissement). Si vous souhaitez que votre enfant puisse en bénéficier, veuillez arriver au moins 30 minutes avant l’heure de votre rendez-vous pour permettre à l’anesthésique d’agir.</p><h2>L’examen exige-t-il une préparation particulière?</h2> <p>Non, votre enfant peut manger et boire comme d’habitude.</p><h2>À l’hôpital SickKids</h2> <p>Si vous avez des questions ou des préoccupations au sujet de ces scintigraphies ou si vous devez changer la date de votre rendez-vous, veuillez communiquer avec le Nuclear Medicine Department au 416 813-6065.​​</p><h2>Source</h2> <p>Alliance for Radiation Safety in Pediatric Imaging (2013). <a href="http://www.imagegently.org/Roles-What-can-I-do/Parent/Nuclear-Medicine" target="_blank"><em>Image Gently: Nuclear Medicine - What can I do as a parent?</em></a></p>
