Decision making tools in the diagnosis of pulmonary embolism by means of SPECT/CT imaging MD., Ph.D, Associate Professor Rimma Axelsson Radiology Department,Karolinska Universitetssjukhus,Huddinge CLINTEK, KI 29 Oktober 2010 Imaging Pulmonary Embolism (PE) • Perfusion scintigraphy ( P or Q) since 1964 evaluating vascular tree and possible occlusions. • In order to improve methods specificity combination with ventilation ( evaluationg bronchial tree) scintigraphy (V) since 1970 • Findings of perfusion defect with preserved ventilation in the corresponding area is called for VQ mismatch and considered as a sign for PE • Planar imaging, 8 projections
X-ray exam VQ scan in patient with PE Criteria for VQ scan interpretation: modified PIOPED • Normal - no perfusion defects • Very- low probability- Small VQ matches, with a normal chest Xray. Non-segmental perfusion defects, including cardiomegaly, enlarged hila or aorta • Low probability –Large or moderate focal VQ matches involving no more than 50% of the combined lung fields, with no corresponding radiographic abnormalities. Small VQ mismatches, with a normal chest xray • Intermediate probability – difficult to categorize or not described as very low, low or high, including cases with a chest X-ray opacity, pleural fluid or collapse. Single moderate VQ match or mismatch without corresponding radiographic abnormality • High probability – 2 or more moderate/large mismatched perfusion defects. Prior cardiopulmonary disease probably requires more abnormalities(4 or more). Triple match in one lung with one or more mismatch in the other Definition of perfusion defects • Small 25 <strong>och</strong> 75% of a segment
