Background And Purpose: Dual-energy computed tomography (DECT) pulmonary angiography can reliably detect cement pulmonary embolisms (CPEs) and parenchymal perfusion defects. This prospective observational study investigated CPEs in asymptomatic patients using DECT.
Methods: We enrolled 42 patients who underwent vertebroplasty or received cement screws for vertebral augmentation, examining them using spinal computed tomography and DECT pulmonary angiography.

Background: Isolated subsegmental pulmonary embolism (issPE) is a commonly encountered diagnosis. Although the International Classification of Diseases (ICD)-10 codes are used for research, their validity for identifying issPE is unknown. Moreover, issPE diagnosis is challenging, and the findings from radiology reports may conflict with those from expert radiologists.

The purpose of this study is to conduct a literature review on the current role of computed tomography pulmonary angiography (CTPA) in the diagnosis and prognosis of pulmonary embolism (PE). It addresses key topics such as the quantification of the thrombotic burden, its role as a predictor of mortality, new diagnostic techniques that are available, the possibility of analyzing the thrombus composition to differentiate its evolutionary stage, and the applicability of artificial intelligence (AI) in PE through CTPA. The only finding from CTPA that has been validated as a prognostic factor so far is the right ventricle/left ventricle (RV/LV) diameter ratio being >1, which is associated with a 2.

Introduction: Metallic luster dusts are decorative agents for cakes and other confections. While some powders are labeled "non-edible," they are also marketed as "non-toxic." We present a case of a child who developed acute metal pneumonitis after accidental aspiration of metallic luster dust.

Objective: Despite the high sensitivity and specificity of ventilation/perfusion (VQ) scintigraphy in the diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) and chronic thromboembolic disease (CTED), V/Q scintigraphy cannot distinguish whether the thrombus is acute or chronic. In our study, we aimed to compare pulmonary computed tomography angiography (CTA) findings with V/Q scintigraphy findings in CTEPH and CTED patients and to identify findings that would indicate chronic thrombus.
Subjects And Methods: Eighteen patients diagnosed with CTEPH and CTED at our institution were included in the study between January 2020 and January 2024.
