TY - JOUR T1 - A Pictorial Essay of Non Embolic Findings on VQ SPECT JF - Journal of Nuclear Medicine JO - J Nucl Med SP - 2015 LP - 2015 VL - 62 IS - supplement 1 AU - Emilie Vallee AU - Khun Visith Keu Y1 - 2021/05/01 UR - http://jnm.snmjournals.org/content/62/supplement_1/2015.abstract N2 - 2015Objectives: Ventilation-perfusion scintigraphy is common study in nuclear medicine and usually performed to exclude pulmonary embolism (PE). Single photon emission computed tomography (SPECT) provides high contrast three dimensional images of the regional distribution of a radiotracer, thus providing a better understanding of the anatomy and pattern of findings. This pictorial assay demonstrates a variety of findings on VQ SPECT that all residents and nuclear medicine physicians must know for an accurate diagnosis of non-embolic conditions. Methods and Results: The current guidelines suggest CT pulmonary angiography as the most appropriate study to exclude PE when the chest radiograph is abnormal. Ten different cases when VQ SPECT has established an accurate diagnosis in the context of an abnormal chest radiograph, are presented. All cases have a pertinent history, a chest x-ray, a differential diagnosis and a discussion section with pearls. Some cases will highlighted the role of hybrid imaging VQ SPECT-CT. Conclusions: Non-embolic findings on VQ SPECT are easy to recognize. Theses cases are highly valuable to the nuclear medicine community and easy to learn. Having the ability to diagnose other conditions on VQ SPECT is an adding-value for the referring physician. ER -
