V/Q PET/CT imaging is now possible by substituting 99mTc with 68Ga, a positron-emitting radionuclide, using the same carrier molecules as conventional V/Q imaging. Ventilation imaging can be performed with 68Ga-carbon nanoparticles using the same synthesis device as Technegas. Perfusion imaging can be performed with 68Ga-macroaggregated albumin (68Ga-MAA).Technical advantages of PET compared to SPECT include higher sensitivity, higher spatial and temporal resolution and superior quantitative capability. This offers the opportunity to improve the accuracy of V/Q imaging in patients with suspected PE, while decreasing the acquisition time. The aim is to perform a formal diagnostic accuracy study of V/Q PET/CT for PE, using CTPA as a reference standard. Patients with suspected acute PE undergo CTPA and V/Q PET/CT imaging within 24 hours. V/Q PET/CT images are not used for patients management. After completion of inclusion, central readings of scans will be conducted independently.
