Pulmonary embolism | Radiology Reference Article - Radiopaedia.org
2024年8月15日 · It is difficult to obtain technically adequate images for pulmonary embolism patients using MRI. Magnetic resonance pulmonary angiography (MRPA) should be considered only at centers that routinely perform it well and only …
Imaging of acute pulmonary embolism: an update - PMC
MRI, magnetic resonance imaging; PE, pulmonary embolism. MRI allows for visualization of PE on pulmonary perfusion images as areas of reduced, delayed, or absent blood flow. MR perfusion imaging has a high sensitivity for detecting PE and it is often used in …
Magnetic Resonance Imaging for the Evaluation of Pulmonary Embolism
2016年11月28日 · MR imaging offers a wide variety of techniques for directly evaluating the pulmonary arteries and for indirectly assessing other organs for pathologies that can arise secondary to pulmonary artery disease. The technique best suited to directly evaluate the pulmonary arteries is contrast-enhanced MRA (CE-MRA).
Comparison between CT and MRI in the assessment of pulmonary embolism
Besides pulmonary arteriography, a number of imaging techniques, such as magnetic resonance imaging (MRI) and computed tomography (CT), were adopted in the detection of identifying pulmonary embolism (PE).
Role of MRI in diagnosis of pulmonary embolism
2023年8月9日 · Our study aims to assess the role of non-contrast MRA in diagnosis of acute pulmonary embolism compared to either CT pulmonary angiography or contrast enhanced MRA. In total, 50 patients with PE confirmed by either CTPA or CE-MRA were included in this study.
Clinical and imaging aspects of pulmonary embolism: a primer …
Taking this into account, our review paper provides the audience with a comprehensive understanding of the clinical aspects of pulmonary embolism and the imaging modalities used for PE detection. The main focus is on CTPA, its acquisition protocols, and the various incidental findings and artifacts to look for while interpreting a CTPA scan.
Magnetic Resonance Imaging (MRI) in Pulmonary Embolism (PE)
2024年11月21日 · Magnetic Resonance Imaging (MRI) has emerged as a promising alternative to CTPA for the diagnosis of PE, particularly in patients with contraindications to CT or in those in whom ionizing radiation exposure should be minimized (Tsuchiya et al. 2018). Ionizing radiation exposure associated with CTPA is a concern particularly for pregnant women.
MRI for the diagnosis of pulmonary embolism - Wiley Online …
New sequences were developed to enable lung perfusion MRI, direct thrombus imaging of the entire venous system, and, more recently, the introduction of hyperpolarized 3‐helium, which allows high‐resolution lung ventilation imaging.
MR Imaging of Pulmonary Embolism: Diagnostic Accuracy of …
2012年4月1日 · We show that 3D gradient echo and cardiac- and respiratory-triggered true fast imaging with steady-state precession MR sequences provided sensitive imaging for detection of pulmonary embolism (PE) compared with standard MR pulmonary angiography; the combination of all three imaging techniques further improved detection of PE.
Acute Pulmonary Embolism: Imaging Techniques, Findings, Endovascular ...
Ventilation and perfusion (VQ) scanning or - in centers with adequate expertise - magnetic resonance imaging (MRI) is indicated in pregnant or young patients and patients with contraindications to iodinated contrast. Invasive angiography is reserved for patients with intended endovascular treatment.
