In patients with symptoms of a peripheral neuropathy especially during pregnancy, use of imaging techniques such as Ultrasound (US) and Magnetic Resonance Imaging (MRI) may be essential for the diagnostic accomplishment. A 30-weekspregnant diabetic female attending US evaluation due to intermittent hand pain, numbness, and weakness bilaterally. Although, the US evaluation revealed the median nerve (MN) normal size, echogenicity and echo-texture within the right carpal tunnel; the US assessment applied proximally to the carpal tunnel, revealed a hypoechoic tumor-like mass and increased MN cross section area...

Burkitt's lymphoma is an aggressive B-cell non-Hodgkin lymphoma. It is less common in adults accounting for less than 5% of non-Hodgkin lymphoma cases. Radiological methods (ultrasonography, computed tomography) are indispensable for the initial evaluation and appreciation of organ extension; complete diagnosis is confirmed by the histopathological examination.We present the clinical case and ultrasound imaging particularities of a young patient diagnosed with multisystem involvement Burkitt's lymphoma, with rapid progressive evolution towards exitus...

Definitive diagnosis of penile masses usually depends on clinical symptoms and patient history but in some challenging cases the help of radiologic diagnostic tools is required. Although ultrasound is an effective tool for detecting penile masses, unlike magnetic resonance imagining, it is not able to differentiate benign and malignant pathologies. Shear wave elastography (SWE) is a novel method, which has the ability to differentiate malignant and benign tissues by giving quantitative information about tissue elasticity...

Transthoracic echocardiography (TTE) has become one of the most important diagnostic tools in the treatment of critically ill patients. It allows clinicians to recognise potentially reversible life-threatening situations and is also very effective in the monitoring of the fluid status of patients, slowly substituting invasive methods in the intensive care unit. Hemodynamic assessment is based on a few static and dynamic parameters. Dynamic parameters change during the respiratory cycle in mechanical ventilation and the level of this change directly corresponds to fluid responsiveness...

Complete atrioventricular septal defect (CAVSD) is a fetal cardiac malformation (5% of all cardiac malformations) that can be detected prenatally with a reserved prognosis. The diagnosis can be suspected early at the end of the first trimester using the transabdominal or transvaginal ultrasound approach. Generally, the diagnostic can be established during the mid-trimester scan at 19-24 weeks of gestation. The percentage of antenatal diagnostic of CAVSD is between 57-92%. This review aims to analyze the anatomical principles and the ultrasound techniques that can improve the prenatal diagnosis of CAVSD...

The science of lung ultrasound has grown tremendously over the last two decades and lung ultrasound has not only entered the mainstream of point of care ultrasound but has become a dominant topic. Understanding lung ultrasound signs and artifacts is critical to being able to correlate findings with actual pathology and normal anatomy and physiology. Investigators have described multiple lung ultrasound artifacts and findings and it is important to understand both the physics and anatomic basis behind them...

REVIEW

Liver fibrosis scoring by liver biopsy has become a rarity in daily practice mainly because many non-invasive methods with similar accuracy have been developed. Among all ultrasound elastography imaging methods, Strain Elastography (SE) is the most widely available. Although SE is a qualitative and semi-quantitative method, there is reliable applicability for liver fibrosis estimation and multiple ways to transform SE into a quantitative method, in order to obtain a fibrosis score. The aim of this review is to briefly introduce all these methods and to offer support in choosing the best estimation method for liver fibrosis, with SE...

We report a series of six consecutive cases of Takotsubo Cardiomyopathy (TCM) presenting as ST-elevation acute myocardial infarction and consequently addressed to the emergency coronary angiography, inside a time-frame of one year (2015). This series underlines the wide possible triggering spectrum and clinical severity of TCM and recognizes echocardiography as an essential imaging technique in the diagnosis due to its widespread availability and feasibility in the acute care setting.

AIMS: The aim of the study was to evaluate the diagnostic ability of sonovaginography (SVG) with ultrasound gel in patients with endometriosis. MATERIAL AND METHODS: We conducted a multicentre prospective study, which included 193 patients with symptoms highly suggestive for endometriosis. All patients were investigated by transvaginal sonography and SVG with gel and afterwards underwent laparoscopic surgery. For each category of endometriotic lesions investigated, we calculated and compared the sensitivity, specificity,  positive predictive value and negative predictive value of the imagisticinvestigations used...

OBJECTIVE: To identify and analyse existing data regarding knee ultrasound (US) feasibility in clinical practice. Material and methods: A systematic literature review was performed using the terms: ("knee") AND ("ultrasound" OR "ultrasonography") AND ("feasibility" OR "pilot" OR "proof of concept"). Feasibility studies regarding knee US or US aided maneuver involving knee joint, published during 2005-2015, were selected and evaluated against a complex framework constructed around mandatory key areas for feasibility studies: acceptability, demand, implementation, practicality, adaptation, integration and expansion...

AIMS: To evaluate the capacity of virtual touch imaging (VTI) of the acoustic radiation force impulse (ARFI) techniquein the differential diagnosis of micro-echogenicities in thyroid nodules. MATERIAL AND METHODS: The study comprised 28patients. Gray scale and ARFI displacement maps were used during ultrasound examination.In the same session, fine needleaspiration biopsy (FNAB) samples were obtained from the dominant nodule hav-ing micro-echogenicities. Two radiologists blinded to the FNAB results and clinical data of the patients evaluated these images and rated ARFI echogenicities according to the degree of shining points on the displacement maps and classified them as isohypoechogenic, isohyperechogenic, and obvious hyperechogenic...

AIM: The purpose of this study was to determine the significance of a non-mass lesion (NML) which is recognized during screening breast ultrasound (US). MATERIALS AND METHODS: We included patients with a NML on screening breast US and no suspicious finding on mammography between March 2008 and June 2012. The final diagnoses were based on pathology results and a clinical or sonographic follow-up for more than 12 months. We calculated the incidence, likelihood of malignancy, and positive predictive value (PPV) of biopsy with a review of imaging and histopathological findings...

AIM: This study aimed to investigate the effect of microbubble-enhanced ultrasound (MEUS) combined with prothrombin on regional hepatic circulation and microwave ablation (MWA) in rabbit livers. MATERIALS AND METHODS: High-pressureamplitude therapeutic ultrasound (TUS) was used to treat 52 surgically exposed livers of healthy New Zealand rabbits: 13 livers were treated with MEUS alone, 13 with MEUS and prothrombin (PMEUS), 13 with ultrasound plus normal saline and 13 with ultrasound plus prothrombin as controls...

AIMS: To compare the accuracy of the ultrasound attenuation index (USAI) and hepato-renal index (HRI) for the diagnosis of hepatic steatosis (HS). MATERIAL AND METHODS: Two hundred and twenty-four potential living hepatic donors underwent US and subsequent US-guided liver biopsy. The USAI was calculated from US images with an 8 MHz transducer and HRI was measured on sagittal images with a clear visualization of both the liver and kidney. Using histological degrees of HS as the reference standard, we compared the performance of USAI and HRI for diagnosing HS ≥ 5% and ≥ 30% by receiver operating characteristic curve analysis...
