Which is Better – A Standalone Ventilation or Perfusion Scan or Combined Imaging to Predict Postoperative FEV1 in One Seconds in Patients Posted for Lung Surgeries with Borderline Pulmonary Reserve
Combined V/Q scans are recommended in patients with borderline low respiratory reserve for postoperative FEV1 prediction. Being inexpensive and easy to perform investigations, V/Q scans can be used to accurately estimate the surgical operability in these patients. V/Q scans accurately define the edges of the lungs and quantify amounts of penetration beyong the occluded lung regions. This allows one to decide on functional operability in patients with severe lung disease and comorbidities. Further, postoperative performance is accurately predicted by radionuclide investigations by providing anatomical delineation of the exact lung tissue to be resected.
