Role of noncontrast magnetic resonance pulmonary imaging in diagnosis of pulmonary embolism

open access: yesEgyptian Journal of Chest Disease and Tuberculosis, 2022
Background Pulmonary embolism (PE) is a serious condition and has a clinical dilemma in diagnosis. Computed tomography pulmonary angiography (CTPA) is a gold standard in its diagnosis, but MRI has proven a good role in PE diagnosis.

A New Approach in Risk Stratification by Coronary CT Angiography. [PDF]

open access: yes, 2014
For a decade, coronary computed tomographic angiography (CCTA) has been used as a promising noninvasive modality for the assessment of coronary artery disease (CAD) as well as cardiovascular risks.

Successful management of retropharyngeal hematoma by trans-arterial embolism without intubation

open access: yesInternational Journal of Emergency Medicine, 2021
Background Retropharyngeal hematoma can cause suffocation if there is delay in securing the airway by intubation. However, there are also concerns about complications that can arise with intubation; it is still unknown which cases do not require ...

Inflammatory Markers Associated With Subclinical Coronary Artery Disease: The Multicenter AIDS Cohort Study. [PDF]

open access: yes, 2016
BackgroundDespite evidence for higher risk of coronary artery disease among HIV+ individuals, the underlying mechanisms are not well understood. We investigated associations of inflammatory markers with subclinical coronary artery disease in 923 ...

Massive hemoptysis treated with embolization of an ectopic bronchial artery arising from the right thyrocervical trunk: a case report

open access: yesCVIR Endovascular, 2022
Background Ectopic bronchial artery and non-bronchial systemic arteries may be the culprit vessels of hemoptysis. The main cause of clinical failure of bronchial artery embolization is incomplete embolization caused by the misidentification of the ...

Utility of four-dimensional computed tomography angiography for evaluating the mobility of a thrombus in the ascending aorta

open access: yesRadiology Case Reports, 2020
Four-dimensional computed tomography has been used to evaluate moving structures and is a useful method to diagnose cardiovascular diseases. We report a case of cerebral infarction due to the thrombus in the ascending aorta, and utilized 4-dimensional ...

Anatomical variants and coronary anomalies detected by dual-source coronary computed tomography angiography in North-eastern Thailand [PDF]

open access: yes, 2018
Purpose: Congenital coronary anomalies are uncommon, with an incidence ranging from 0.17% in autopsy cases to 1.2% in angiographically evaluated cases. The recent development of dual-source coronary computed tomography angiography (coronary CTA) allows ...

Beam hardening artifact reduction using dual energy computed tomography: implications for myocardial perfusion studies [PDF]

open access: yes, 2015
Background: Myocardial perfusion computed tomography (CTP) using conventional single energy (SE) imaging is influenced by the presence of beam hardening artifacts (BHA), occasionally resembling perfusion defects and commonly observed at the left ...
