Hyperacute direct thrombus imaging using computed tomography and gold nanoparticles

Annals of Neurology, 2013
ObjectiveAdvancing the understanding and management of thromboembolic stroke requires simple and robust new methods that would be useful for the in vivo assessment of thrombus burden/distribution and for characterizing its evolution in a prompt and quantitative manner.MethodsAnimals (n=127) with experimental models of thrombosis were imaged with ...

USPIO-enhanced Direct MR Imaging of Thrombus: Preclinical Evaluation in Rabbits

Radiology, 2001
To test the hypothesis that ultrasmall superparamagnetic iron oxide (USPIO) particles may diffuse into nonendothelialized fresh thrombi and thus allow for direct magnetic resonance (MR) imaging of a thrombus.Stagnation thrombi of different thrombus ages (1, 3, 5, 7, and 9 days) were induced in the external jugular veins of 25 rabbits. Direct MR imaging

Lower-limb deep venous thrombosis: direct MR imaging of the thrombus.

Radiology, 1998
To determine the feasibility of diagnosing deep venous thrombosis (DVT) with direct three-dimensional magnetic resonance (MR) imaging of the thrombus.Eighteen patients with proved DVT at conventional venography were evaluated with a magnetization-prepared three-dimensional blood- and fat-suppressed MR imaging sequence.

Magnetic resonance direct thrombus imaging differentiates acute recurrent ipsilateral deep vein thrombosis from residual thrombosis

Blood, 2014
Key Points Diagnostic management of ipsilateral recurrent DVT of the leg is complicated because residual DVT is common and mimics acute DVT on CUS. MRDTI is able to reproducibly distinguish acute ipsilateral recurrent DVT from 6-month-old chronic residual thrombi in the leg veins.

Is Deep-Vein Thrombosis Always the Origin of Pulmonary Embolism? Imaging of Veins with a Total-Body Direct Thrombus MRI Technique

Blood, 2011
Abstract Abstract 2297 Introduction Pulmonary embolism (PE) is thought to originate from embolisation of a deep-vein thrombosis (DVT), resulting in two clinical manifestations of one disease: venous thrombosis.

Easy interpretation of MR-direct thrombus imaging in diagnosing thrombosis in the leg

2010
Purpose: Ultrasonography is clinical routine in diagnosing deep vein thrombosis (DVT), but has limitations, in particular in recurrent thrombosis and in the hands of a non-experienced ultrasonographist.

In Vivo Identification of Complicated Upper Thoracic Aorta and Arch Vessel Plaque by MR Direct Thrombus Imaging in Patients Investigated for Cerebrovascular Disease

American Journal of Roentgenology, 2006
The objective of this article was to assess the feasibility of MR direct thrombus imaging (MRDTI) to evaluate the prevalence and location of complicated upper thoracic aortic and arch vessel plaque in patients referred for evaluation of cerebrovascular disease.Patients referred for investigation of cerebrovascular disease by MRI were enrolled.

Direct abdominal vein thrombus imaging (DATI): a contrast-free black-blood MR technique for the diagnosis of abdominal vein thrombosis

Abdominal Radiology
To develop and evaluate a direct abdominal vein thrombus imaging (DATI) technique, based on a respiratory navigating SPACE sequence with DANTE black-blood preparation, for diagnosing abdominal vein thrombosis (AVT) without the use of exogenous contrast agents.We prospectively enrolled 10 healthy subjects and 28 suspected AVT patients who underwent DATI

Accuracy of Magnetic Resonance Direct Thrombus Imaging (MRDTI) As a Novel Tool in the Diagnosis of Acute Ipsilateral Recurrent Deep Vein Thrombosis

Blood, 2012
Abstract Abstract 395 Background Accurate diagnostic assessment of suspected acute ipsilateral recurrent deep vein thrombosis (DVT) is of high clinical importance, however discriminating residual thrombosis from acute recurrent DVT may be challenging.
