Time-of-flight MR angiography of carotid artery stenosis: does a flow void represent severe stenosis?
BACKGROUND AND PURPOSE Time-of-flight (TOF) magnetic resonance angiography (MRA) is commonly used to visualize the carotid arteries; however, flow void artifacts can appear. Our purpose was to determine the frequency and diagnostic meaning of flow voids by using real patient data, as part of a larger study of MRA compared with the criterion standard, digital subtraction angiography (DSA). MET...
متن کاملIterative Soft-Thresholding Reconstruction for Time-of-Flight MR Angiography
Introduction: Time-of-Flight MR angiography (TOF-MRA) is a non-invasive technique that utilizes the signal enhancement due to blood inflow effects for imaging the blood vessel anatomy. Vascular images are inherently sparse and can be made even sparser in a suitable transform domain (e.g. wavelet transform), making MR angiography a natural application of Compressed Sensing (CS) [1]. There are tw...
متن کاملPostcontrast time-of-flight MR angiography demonstrating collateral flow in acute stroke.
Postcontrast Time-of-Flight MR Angiography Demonstrating Collateral Flow in Acute Stroke To the Editor: In their interesting study, Pedraza et al1 showed that the postperfusion contrast-enhanced time-of-flight (TOF) MR angiography (Post-CE-MRA) can demonstrate arterial segment with low flow and avoid overestimation of vascular obstruction. We agree that Post-CE-MRA supplies additional informati...
متن کاملBenign simulators of melanoma on dermoscopy – black colour does not always indicate melanoma
Introduction: Simulators of malignant melanoma comprise a heterogeneous group of melanocytic and nonmelanocytic lesions of the skin. They are mainly characterized by the occurrence of black or blue-black colors – both in clinical diagnosis as on dermoscopy. Therefore the proper recognition of this cases is extremely needed in daily general practice of many specialties’ doctors. Objective: The a...
متن کاملDoes Prolactin Indicate Severity of Psoriasis?
Background: Psoriasis vulgaris is a common chronic and inflammatory disease of skin that its etiology is not completely known. However, it seems that genetic and environmental factors play a role in this disease. In vitro studies show that prolactin as a neurohormone has an etiologic effect on psoriasis. This study aimed to compare serum prolactin levels in psoriatic patients with control group...
