Abstract

OBJECTIVE:

The purpose of this article is to outline recent progress made in ventilation-perfusion (V/Q) scintigraphy imaging techniques and the interpretation systems used for the diagnosis of pulmonary embolism (PE). Various state-of-the-art approaches that can be selected according to the needs dictated by the medical practice environment and specific patient groups are presented.

CONCLUSION:

Although advances in tomographic imaging have certainly improved the sensitivity of V/Q scans for the diagnosis of PE, they may lead to overdiagnosis by revealing small and clinically insignificant PEs.

KEYWORDS:

V/Q reporting; pulmonary embolism; pulmonary embolism overdiagnosis; pulmonary embolism overtreatment; pulmonary embolism tomographic imaging
