Diagnostic accuracy of non-contrast magnetic resonance angiogram of infra-popliteal arteries prior to fibular-free flap harvest
نویسندگان
چکیده
Background Patients who are being evaluated to undergo fibula free flap transfer often do not have arterial disease. However a significant anatomical variant cannot be clinically excluded. Contrast enhanced magnetic resonance angiogram (CE-MRA) is commonly performed to identify the suitable side to harvest the flap and to exclude unsuitable infra-popliteal arterial anatomy. The aim of this study is to measure the quality and accuracy of a noncontrast MRA (NC-MRA) technique (Native SPACE = Non-contrast Angiography of the Arteries and Veins using Sampling Perfection with Application Optimized Contrast by using different flip angle Evolution) compared to CE-MRA.

To investigate and control quality, one must be able to measure quality-related attributes. Quality of produce encompasses sensory attributes, nutritive values, chemical constituents, mechanical properties, functional properties and defects. MRI has great potential for evaluating the quality of fruits and vegetables. The equipment now available is not feasible for routine quality testing. The ...

Patients with critical limb ischemia necessitate immediate intervention to restore blood flow to the affected limb. Endovascular procedures are currently preferred for these patients. We describe the case of an 80-year-old female patient who presented to our department with ischemic rest pain and ulceration of the left limb. The patient had history of left femoral popliteal bypass surgery, femo...

Introduction: Bacterial meningitis is an acute infectious inflammation of the protective membranes covering the brain. Its early diagnosis is vital because of its high morbidity and mortality. It is mostly diagnosed by a gold standard diagnostic tool i.e. Cerebrospinal Fluid (CSF) analysis. However, it is sometimes difficult and or impossible to do this procedure and an alternative diagnostic t...
