Neuroimaging of midbrain structures with different phased-array ultrasound systems

Purpose: Transcranial sonography (TCS) has been recently used to detect alterations in the echo pattern of the basal ganglia in movement disorders. Data about the impact of the TCS equipment on depiction of basal ganglia are not yet available. Aim of the study was to compare the feasibility of two different ultrasound systems to determine the echo pattern of brain parenchyma. Methods: TCS was performed through the temporal bone window in twenty-four subjects (age: 20–77yrs). Two phased-array ultrasound systems (A – Sonoline Elegra; B – Sonoline Antares) equipped with a 2–2.5MHz transducer (2.5PL20, PX4–1, PH4–1;…
