The purpose of this guideline from the Society of Nuclear Medicine (SNM) is to assist nuclear medicine practitioners in recommending, performing, interpreting, and reporting the results of lung ventilation and perfusion scintigraphy for pulmonary embolism.
Pulmonary embolism (PE) can only be diagnosed with imaging techniques, in practice using ventilation/perfusion (V/P) scintigraphy or multidetector computed tomography (MDCT) of the pulmonary arteries. The objective of Part 1 of these European Association of Nuclear Medicine (EANM) guidelines is to develop a methodological approach and interpretation criteria for PE with a focus on V/P SPECT.
The primary objective of these European Association of Nuclear Medicine (EANM) guidelines is to deliver recommendations for the appropriate use of ventilation/perfusion scintigraphy for the diagnosis and follow up of PE. The specific objectives of this second part are to define the importance of clinical probability together with objective imaging tests and to analyze the relative advantages and disadvantages of V/P SPECT and MDCT.
This guideline was revised collaboratively by the American College of Radiology (ACR), the Society for Pediatric Radiology (SPR), and the Society of Nuclear Medicine (SNM). It is intended to guide physicians performing pulmonary scintigraphy in adult and pediatric patients. Properly performed ventilation imaging with radioaerosol or gaseous radiopharmaceuticals and perfusion imaging with technetium-99m-labeled perfusion agents that localize by temporary capillary blockade are sensitive tools for detecting certain kinds of pulmonary abnormalities. Correlation with clinical data and current chest radiographs is imperative to optimize the interpretation of images.
The purpose of this guideline is to offer the nuclear medicine team a helpful framework in daily practice. This guideline deals with the indications, acquisition, processing and interpretation of lung scintigraphy in children.
