Introduction: Coronary angiography and angioplasty procedures lead to significant radiation exposure of patients. In the current study, the average radiation dose to patients during angiography in the Angiography Department of Shahid-Madani Hospital was determined. Materials and Methods: An image intensifier based angiography unit (Philips BH 3000) was used for angiography procedures. The accur...

X-ray radiographic absorption imaging is an invaluable tool in medical diagnostics and materials science. For biological tissue samples, polymers, or fiber composites, however, the use of conventional X-ray radiography is limited due to their weak absorption. This is resolved at highly brilliant X-ray synchrotron or micro-focus sources by using phase-sensitive imaging methods to improve contras...

Scimitar syndrome is characterized by partial or total anomalous pulmonary venous return from the right lung along with pulmonary hypoplasia.Wesearched the mail databases such as Medline (via PubMed), Scopus and EMBASE and Google Scholar. Diagnosing infantile scimitar syndrome requires meticulous attention and high suspicion of the early referral and management. The association of the syndrome ...

o bjectives: to determine the diagnostic accuracy of magnetic resonance angiography (mra) compared to intra-arterial digital subtraction angiography (dsa) in detection of intracranial aneurysms in those suffering from acute subarachnoid hemorrhage (sah). m e thods: this observational diagnostic study was performed at a tertiary teaching hospital and reference center in shiraz, iran. we included...

Background and Objective: Coronary artery disease (CAD) is one of the most common diseases today. Among the diagnostic methods, angiography is the main and gold standard in the diagnosis Since angiography is an invasive procedure, this procedure complications range widely from minor problems with short term sequelae to life threatening ones may cause irreversible damage or even death. Materials...

Background: Coronary angiography consists of the selective injection of contrast agents in coronary arteries. Optimal strategy for heparin administration during coronary angiography has yet to be determined. We assessed the effect of heparin administration during coronary angiography on vascular, hemorrhagic, and ischemic complications.Methods: Five hundred candiates for diagnostic coronary ang...

OBJECTIVE Although three-dimensional time-of-flight magnetic resonance angiography (3D TOF-MRA) is used frequently as a follow-up tool to assess the response of arteriovenous malformations (AVMs) after radiosurgery, the diagnostic accuracy of 3D TOF-MRA is not well known. We evaluated the diagnostic accuracy of contrast-enhanced 3D TOF-MRA at 3.0 Tesla for the detection of residual AVMs. MATE...

SARS-CoV-2 is a virus of the coronavidae family that causes COVID-19, disease emerged in 2019 and has already gone around world, causing World Health Organization to decree pandemic state 2020. One consequences COVID-19 development Pulmonary Thromboembolism (PE), which one or more pulmonary arteries are blocked by blood clot. In this association with PE caused pro-inflammatory hypercoagulant de...
