Differentiation of Breast Lesions and Distinguishing Their Histological Subtypes Using Diffusion-Weighted Imaging and ADC Values.

Diffusion-weighted imaging (DWI) has not been well explored in differentiation of malignant from benign breast lesions. The aims of this study were to examine the role of apparent diffusion coefficient (ADC) values in differentiation of malignant from benign tumors and distinguishing histological subtypes of malignant lesions, and to determine correlations between ADC values and breast tumors structure. This cohort-study included 174 female patients who underwent contrast-enhanced breast MR examination on a 3T scanner and were divided into two groups: patient group (114 patients with proven tumors) and control group (60 healthy patients).

Dynamic simulation and Doppler Ultrasonography validation of blood flow behavior in Abdominal Aortic Aneurysm.

Criteria for rupture prediction of Abdominal Aortic Aneurysm (AAA) are based only on the diameter of AAA. This method does not consider complex hemodynamic forces exerted on AAA wall. The methodology used in our study combines Computer-Aided Design (CAD) with Computational Fluid Dynamics (CFD).

Cystatin C, vascular biomarkers and measured glomerular filtration rate in patients with unresponsive hypertensive phenotype: a pilot study.

Background: Biomarkers are commonly used to estimate the presence of subclinical cardiovascular disease (CVD) in patients with essential arterial hypertension (HT). In addition to known association between cystatin C and glomerular filtration rate (GFR), elucidating the association between cystatin C and vascular biomarkers (intima-media thickness of common carotid arteries (CCIMT), carotid plaque and renal artery resistance index (RRI)) in patients with unresponsive hypertensive phenotype could be of significant clinical interest.

Methods: Participants (n = 200, median age 58 (52-64) years, 49% female) under treatment with antihypertensive drugs were stratified into two subgroups based on their blood pressure level as having responsive hypertension (RHT - compliant and responsive to treatment, n = 100), or nonresponsive (URHT - compliant but nonresponsive to treatment, n = 100).

The role of the color Doppler ultrasonography and computed tomography in estimation of portal hypertension.

Introduction: Liver diseases with disturbances of hepatic and splanchnic circulation lead to the portal hypertension, with or without a portal vein thrombosis.

Objective: This study was based on the testing of hypothesis that more data and more precise diagnosis in patients with disorders of portal circulation can be obtained by using color Doppler ultrasonography (CDU) and computed tomography (CT) with contrast.

Methods: The study was conducted from February 2011 to May 2014 and it comprised 120 patients who were suspected to have portal hypertension or already had clinical confirmation of the portal hypertension, patients with hepatitis, and some patients with hematological diseases.

Dirofilariasis of the breast: sonographic appearance.

Human dirofilarial infections characteristically manifest as pulmonary "coin" lesions or as subcutaneous nodules. A case of subcutaneous Dirofilaria infection of the breast involving a 25-year-old woman with a painful breast lump is presented. The patient had not traveled anywhere and did not have any animals, but provided a history of being bitten by mosquitoes.

Blunt trauma of bone structures of the chest--computed tomography vs multidetector computed tomography.

Background/aim: Computerized tomography (CT), especially multidetector CT (MDCT), has had a revolutionary impact in diagnostic in traumatized patients. The aim of the study was to identify and compare the frequency of injuries to bone structures of the thorax displayed with 5-mm-thick axial CT slices and thin-slice (MDCT) examination with the use of 3D reconstructions, primarily multiplanar reformations (MPR).

Methods: This prospective study included 61 patients with blunt trauma submitted to CT scan of the thorax as initial assessment.

Color Doppler ultrasonography and multislice computer tomography angiography in carotid plaque detection and characterization.

Background/aim: Cerebrovascular diseases are the third leading cause of mortality in the world, following malignant and cardiovascular diseases. Therefore, their timely and precise diagnostics is of great importance. The aim of this study was to compare duplex scan Color Doppler ultrasonography (CDU) with multislice computed tomography angiography (MSCTA) in detection of morphological and functional disorders at extracranial level of carotid arteries.

Multislice computed tomography urography in the diagnosis of urinary tract diseases.

Background/aim: . Multislice computed tomography (MSCT) has triggered considerable changes in uroradiological imaging. The aim of this study was to establish the place of MSCT urography (MSCTU) in comparison with intravenous urography (IVU) and to determine the sensitivity and specificity of MSCT in the evaluation of urothelial abnormalities.

[Chest computed tomography in the localisation of pathologic processes in lymphomas].

Introduction: The anatomic localisation of Hodgkin disease and Non-Hodgkin lymphoma is very important in the disease prognosis and therapy treatment. Intrathoracic localisation in Hodgkin disease is very frequent and usually occurs in the form of lymph node enlargement. The most frequent manifestation of the thoracic Non-Hodgkin lymphoma is mediastinal and hilarlympha-denomegalia.

[Blunt injuries of the lungs, pleura and chest bone structures: computed tomography contribution].

Introduction: The most frequent incidences of blunt chest injuries occur due to motorvehicle accidents, falls and work-related traumas. Chest computed tomography is usually associated with examination of the subsequent regions with the aim to enable a more efficient diagnostic procedure. The purpose of this research study is to define the contribution of the chest CT in blunt injury patients.

Renal colic--radiological approach.

Acute flank pain is commonly caused by urolithiasis. This paper discusses advantages and disadvantages of procedures used for evaluation of acute flank pain. In our institution, the diagnostic algorithm includes ultrasonography and plain film radiography, and unenhanced spiral CT in equivocal cases.

[Duplex Doppler ultrasonography in the diagnosis of deep venous thrombosis of the lower extremities].

Introduction: The aim of this study was to investigate the role of duplex Doppler ultrasonography in diagnosis of deep venous thrombosis (DVT) of the lower extremities.

Material And Methods: During a 2-year period, 860 patients were examined by duplex Doppler sonography. Among these, 619 (72%) were women and 241 (28%) men, with the age-range of 16-91; (mean 56,2) years.

[Basic characteristics of duplex sonography in the assessment of lower limb arterial circulation].

Introduction: Dulpex and color duplex ultrasonography of lower limb arteries are valuable non-invasive diagnostic methods in the pathology of vascular diseases and a major step in diagnostics and in follow-up of hemodynamic and morphologic characteristics.

Color Duplex Sonography: The method consists of image analysis and analysis of Doppler information. Real-time-B mode is used to visualize the anatomy of blood vessels and other pathological lesions.
