[Importance of Skull X-ray in Head Trauma].

PURPOSE OF THE STUDY The aim of our study is to show the pitfalls of performing skull X-rays in patients with head injuries and the lack of accuracy of this examination nowadays, and to clarify the current trend in the MTBI investigation algorithm. MATERIAL AND METHODS A retrospective study of 3,950 patients treated for acute head injury at the Department of Trauma Surgery (University Hospital Brno) in the period from 2015 to 2016. Inclusion criteria were the following: mild brain injury (GCS = 15), primary skull X-ray design in head injury diagnosis.

Contrast-enhanced ultrasonography in the evaluation of incidental focal liver lesions: A cost-effectiveness analysis.

Aim: To determine whether contrast-enhanced ultrasonography (CEUS) as the first-line method is more cost-effective in evaluating incidentally discovered focal liver lesions (FLLs) than is computed tomography (CT) and magnetic resonance imaging (MRI).

Methods: Between 2010 and 2015, our prospective study enrolled 459 patients with incidentally found FLLs. The biological nature of FLLs was assessed by CEUS in all patients.
