The current diagnostic modality of prostate cancer based on prostate specific antigen (PSA) and systematic biopsy is far from ideal in terms of over-diagnosing indolent prostate cancer and missing significant ones. Thus we integrated the peripheral zone volume ratio (PZ-ratio) for diagnostic refinement. This retrospective study included 247 consecutive patients who underwent initial transrectal ultrasound-guided systematic prostate biopsy from April 2014 to November 2015. Prostate volume was determined by semi-automatic contour on axial T2 weighted magnetic resonance imaging (MRI)...

Approximately 90% of hospitalized patients have a short peripheral intravenous catheter (SPC) placed. Methods of inserting the catheter have evolved over time and now include the use of ultrasound (US)-guided procedures for placement. Little is known about the impact that US-guided procedures have on the vein. This study compared the rate of venous thrombosis in patients with and without US-guided catheter placement. This prospective, single-blind, observational study assessed for venous thrombosis in 153 veins from 135 patients...

OBJECTIVES: A renal extracapsular hypoechoic rim was previously recognized and interpreted as a typical sonographic finding of renal failure. Subsequently it was hypothesized that the hypoechoic rim could be produced by a state of sodium retention and oedema caused by nephropathy but not necessarily associated with renal failure. In order to get this cleared we performed a retrospective analysis of 80 renal ultrasound examinations, carried out at our center, in 41 of which it was found a renal extracapsular hypoechoic rim...

OBJECTIVE: Contrast-enhanced ultrasound (CEUS) imaging is a powerful noninvasive modality offering numerous potential diagnostic and therapeutic applications in vascular medicine. CEUS imaging uses microbubble contrast agents composed of an encapsulating shell surrounding a gaseous core. These microbubbles act as nearly perfect intravascular reflectors of ultrasound energy and may be used to enhance the overall contrast and quality of ultrasound images. The purpose of this narrative review is to survey the current literature regarding CEUS imaging and discuss its diagnostic and therapeutic roles in current vascular and selected nonvascular applications...
