Ultrasound investigation and management of the thyroid nodule.Tirads classification.Patient's follow-up after thyroidectomy.

Thyroid's ultrasound examination is the first and main imaging modality for the morphological investigation of the gland following clinical examination. It depicts both the number and texture of both palpable and non-palpable nodules.

Ultrasound Elastography: another piece in the puzzle of carotid plaque vulnerability?

Recent literature has shown that various carotid plaque features, other than stenosis, contribute to plaque vulnerability. Features such as surface morphology and plaque composition with distinct components (e.g.

Extracranial internal carotid artery occlusive dissection - multimodality presentation in a case series.

Carotid dissection is a rare disease, mainly affecting young and middle-aged patients potentially ending up in stroke. Multimodality imaging plays an essential role, both in terms of prompt and accurate diagnosis and follow-up of this entity. We herein present a case series of patients with internal carotid artery dissection and compare the various imaging findings of ultrasonography, multidetector computed tomography angiography and magnetic resonance angiography, with a purpose to illustrate the value of multimodality imaging in the diagnosis of carotid dissection.

Contrast-enhanced ultrasound of the carotid system: a review of the current literature.

Carotid disease is a major current health problem accounting for a significant part of stroke patients. Ultrasound with colour Doppler and spectral analysis is the primary imaging technique used for screening and diagnostic evaluation of the extracranial part of carotid arteries offering identification and grading of carotid disease. However, inherent limitations of this technique include flow-related artefacts like Doppler angle dependence and aliasing artefact which may sometimes hinder complete assessment of a stenotic part of the vessel, potentially failing to address clinically significant differential diagnosis issues.

The effect of folic acid supplementation on carotid intima-media thickness in patients with cardiovascular risk: a randomized, placebo-controlled trial.

Introduction: Observational studies have suggested a causal relationship between hyperhomocysteinemia and cardiovascular complications such as stroke and ischemic heart disease. The Homocysteine Lowering Trialists' Collaboration has shown that daily administration of folic acid can significantly decrease homocysteine levels up to 25%. Aim of this study was to investigate the effect of daily supplementation of folic acid (5 mg) on IMT after 18 months of treatment in patients with at least one cardiovascular risk factor.

Homocysteine and carotid intima-media thickness in ischemic stroke patients are not correlated.

Introduction: Hyperhomocysteinemia has been linked to cardiovascular morbidity and mortality by numerous authors. Whether this association is causal or not remains uncertain. The aim of the study was to investigate the association of hyperhomocysteinemia with the degree of carotid atherosclerosis in stroke patients.
