Extraprostatic extension in multiparametric MRI; Is presurgical detection possible?

Introduction: Extraprostatic extension (EPE) is one of the important factors affecting the prognosis of prostate cancer (PCa). Therefore, preoperative evaluation of the presence of EPE is essential in multiparametric magnetic resonance imaging (mpMRI) examination. However, for the evaluation of mpMRI, objective criteria are needed to detect EPE, especially microscopic EPE.

Does Early Diabetic Kidney Damage Alter Renal Elasticity? An Ultrasound-Based, Two-Dimensional Shear Wave Elastography Study.

Objective: Kidney damage caused by type 2 diabetes mellitus (T2DM) can reduce renal elasticity. Limited number of data exist indicating whether early kidney damage causes stiffening of renal tissue. This comparative study aims to assess kidney elasticity in T2DM patients with or without moderate albuminuria, using ultrasound-based two-dimensional shear wave velocity (2D-SWV) measurements.

Ultrasound and contrast-enhanced ultrasound (CEUS) in infective liver lesions.

Infektiöse fokale Leberläsionen (FLL) treten in der klinischen Praxis häufig auf, wobei bakterielle Leberabszesse die Hälfte ausmachen. Eine genaue Diagnose der FLL ist für die Auswahl der am besten geeigneten Therapie und zur Vorbeugung von Komplikationen unerlässlich. Ziel der aktuellen Arbeit ist es, den Nutzen von Ultraschall und kontrastmittelverstärktem Ultraschall (CEUS) zur Erkennung und Charakterisierung infektiöser Leberläsionen zu beschreiben.

Purpose: To observe and describe the stiffness changes of the optic nerve in the patients with multiple sclerosis (MS) with or without optic neuritis and healthy adults via shear wave elastography (SWE).

Methods: 70 optic nerves from 35 patients with MS and 60 optic nerves from 30 healthy subjects were included prospectively in the study. The optic nerve (ON), optic disc (OD), and perineural area were evaluated with SWE and optic nerve sheat diameter (ONSD) was measured by ultrasound.

Computed Tomography-based Morphological Differences between Histologic Subtypes of Periampullary Ductal Adenocarcinoma.

Objective: To evaluate the computed tomography (CT)-based differences between pancreaticobiliary (PBST) and intestinal (IST) subtypes of periampullary pancreatic ductal adenocarcinomas (PDAC).

Study Design: Analytical study.

The role of intraoperative ultrasonography in detection of hepatic vein variations in living donor liver transplantation.

Background: With advances in surgical techniques and immunosuppression, liver transplantation has become the most effective treatment of acute and chronic liver failures. Evaluation of vascular anatomy and detection of hepatic vascular variations prior to surgery, especially transplantation surgery, can help reduce complications in both the donor and the recipient. Intraoperative ultrasonography (IOUS) is known to be beneficial during planning of the transplantation surgery, and can help direct the surgery itself.

Cystic renal diseases: role of ultrasound. Part II, genetic cystic renal diseases.

Kidney cysts are quite common in adults. Though small simple renal cysts in an adult over 30-40 years of age are not too unusual, however, if the same cysts are seen in a child, and especially if there are additional findings, then several diagnostic possibilities may come to mind. The role of ultrasound, together with the help of intravenous contrast agents and Doppler mode, are very critical in describing the morphologic features and follow-up of the complex or multiple and bilateral renal cysts.

Imaging appearance of post umbilical venous catheter displacement: liver collections in children.

Umbilical venous catheters (UVCs) have become a part of routine perinatal care. In the case of its misplacement, extravasation into liver parenchyma might be observed and unusual findings might be detected and a suspicion of tumoral lesions emerges during the ultrasound examination. To avoid the unnecessary liver biopsies and catastrophic complications of UVC misplacement in the pediatric population, clinicians and radiologists must be familiar with the radiological findings.

Ultrasound Curricula of Student Education in Europe: Summary of the Experience.

Despite the increasing role of ultrasound, structured ultrasound teaching is only slowly being integrated into the curricula of medical schools and universities all over Europe. To survey the current situation at European universities regarding the integration of ultrasound in student medical education and to report on models of student ultrasound training from selected European universities. A questionnaire survey focusing on the implementation of curricular ultrasound education was sent out to the 28 presidents of the national ultrasound societies of the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB), who were asked to distribute the questionnaires to the medical universities of their countries.

Cystic echinococcosis, review and illustration of non-hepatic manifestations.

Cystic echinococcosis (CE) or hydatidosis (hydatid cysts), is an infection with a wide spectrum of manifestations, from asymptomatic infection to fatal disease. Ultrasound (US) allows screening, diagnosis, differential diagnosis, treatment guidance and follow-up of CE under many circumstances. Hydatid cysts are predominantly observed in the liver but many other organs can be involved.

Objectives: To investigate the utility of shear wave elastography (SWE) in detecting morphologic abnormalities of the median nerve and posterior tibial nerve in transverse and longitudinal axes in adolescents with type 1 diabetes mellitus (DM) without diabetic peripheral neuropathy (DPN).

Methods: The median nerves and posterior tibial nerves of 25 adolescents with diagnosis and follow-up of type 1 DM without DPN and 32 healthy volunteers were evaluated with SWE by 2 observers on the transverse and longitudinal axes. The cross-sectional area and thickness of the nerves and disease duration were noted, and probable associations of these parameters with SWE features were analyzed.

Ultrasound and Cystic Echinococcosis.

The introduction of imaging techniques in clinical practice 40 years ago changed the clinical management of many diseases, including cystic echinococcosis (CE). For the first time cysts were clearly seen before surgery. Among the available imaging techniques, ultrasound (US) has unique properties that can be used to study and manage cystic echinococcosis.
