Retroaortic left renal vein joining the left common iliac vein

Retroaortic left renal vein joining the left common iliac vein is a rare congenital anomaly in the development of the inferior vena cava. To our knowledge, only one case has been reported in the literature; however, its imaging features have never been described. A 27-year-old male presented with a 1-year history of recurrent right flank pain, dysuria, hematuria, and fever (39 degrees C). Computed tomography and MR venography showed a retroaortic left renal vein joining the left common iliac vein. We present the CT and MR venography findings and discuss their feasibility in showing this congenital anomaly.

Role of Imaging in the Assessment of Age Estimation

Age assessment by skeletal age estimation of unknown individuals is of paramount importance in forensic science, both for assessing imputability (if the author of a crime is old enough to be tried and judged), both in case of unaccompanied minors, or whether refugees and asylum seekers are adults or juveniles, which implies different legal issues and procedures. The aim of this article is to review the age estimation methods used in forensic practice.

La termoablazione nel trattamento delle neoplasie epatiche primitive e secondarie

Radiofrequency thermoablation is a locoregional procedure based on the use of electromagnetic waves that induce movement and consequently the production of heat. This is the basis for the coagulative necrosis produced in the tissues. The method, experimented with and developed in the '90s, is today extensively used in the treatment of focal hepatic lesions, both primary and secondary. The factors that condition the procedure are related essentially to the characteristics of the tumours and to the possibility of obtaining a predictable area of necrosis that guarantees the radicality of the treatment. As regards primary neoplasms, it should be stressed that the treatment for hepatocellular ca…

RADIATION-ENGINEERED NANOGELS AS GADOLINIUM VECTORS IN BIO-IMAGING

CT and MR imaging of cystic renal lesions

AbstractCystic renal lesions are a common incidental finding on routinely imaging examinations. Although a benign simple cyst is usually easy to recognize, the same is not true for complex and multifocal cystic renal lesions, whose differential diagnosis includes both neoplastic and non-neoplastic conditions. In this review, we will show a series of cases in order to provide tips to identify benign cysts and differentiate them from malignant ones.

Gadolinium-chelating nanogels as MR contrast agesnts specifically targeting tumor cells

Development of multifunctional nanogels coordinating paramagnetic ions and displacing targeting ligands for preferential accumulation into tumors. Low molecular-weight Gd-chelates are widely used in clinical MRI for various purposes. However, these contrast agents (CAs) have several shortcomings: they rapidly extravasate from blood vessels to the interstitial space, have a short circulation times and show poor contrast at high magnetic fields. Incorporating gadolinium into flexible nanogels has the potential of increasing intravascular half-life, accumulation and retention in specific body compartments of the CA as well as increasing the MR signal, since many metal ions can be coordinated t…

Communicating with the hepatobiliary surgeon through structured report

Communicating radiological findings to hepatobiliary surgeons is not an easy task due to the complexity of liver imaging, coexistence of multiple hepatic lesions and different surgical treatment options. Recently, the adoption and implementation of structured report in everyday clinical practice has been supported to achieve higher quality, more reproducibility in communication and closer adherence to current guidelines. In this review article, we will illustrate the main benefits, strengths and limitations of structured reporting, with particular attention on the advantages and challenges of structured template in the preoperative evaluation of cirrhotic and non-cirrhotic patients with fo…

L'impiego del Tachosil in chirurgia epatica

Il controllo delle perdite ematiche intra e post-operatorie caratterizza da sempre la chirurgia resettiva epatica. Nel corso degli ultimi anni notevoli progressi sono stati compiuti in tale ambito, grazie all'adozione di materiali e strumentari sempre più specifici ed efficaci che consento l'esecuzione di interventi resettivi con minime perdite ematiche ed una significativa riduzione dell'incidenza di complicanze emorragiche post-operatorie. Vengono presentati 2 casi di resezione epatica realizzata utilizzando un manipolo a radiofrequenza senza eseguire il clampaggio del peduncolo epatico e senza l'utilizzo di clips o legature per le piccole perdite dalla trancia di sezione.

Imaging features of adrenal masses

Abstract The widespread use of imaging examinations has increased the detection of incidental adrenal lesions, which are mostly benign and non-functioning adenomas. The differentiation of a benign from a malignant adrenal mass can be crucial especially in oncology patients since it would greatly affect treatment and prognosis. In this setting, imaging plays a key role in the detection and characterization of adrenal lesions, with several imaging tools which can be employed by radiologists. A thorough knowledge of the imaging features of adrenal masses is essential to better characterize these lesions, avoiding a misinterpretation of imaging findings, which frequently overlap between benign …

Strengthening of steel-reinforced concrete structural elements by externally bonded FRP sheets and evaluation of their load carrying capacity to face changed load service conditions

The paper has proposed a limit analysis procedure for a preliminary design of RC elements strengthened by externally bonded FRP sheets. The procedure, based on a multi-yield-criteria limit analysis approach, has led to a reliable prediction of peak loads and failure modes of the analyzed elements (slabs) by simultaneously considering the limit state of the constituent materials, so resulting very useful in many applications of engineering interest. The attention has been focused on hospital applications in which increment of service loads or realization of openings can weaken some structural elements that have been strengthened by FRP sheets.
