CT and MR imaging of cystic renal lesions

2020

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.

Hirnabsze� durch fehlerhafte Crutchfield-Zange

1973

Mitteilung uber einen Fall von Hirnabszes nach Anwendung der Crutch-field-Zange. Ursache: Fehlende Kropfung am Dorn der Zange, der so den gesamten Schadelknochen und die Dura mater durchdringen konnte. Unerlaslich ist eine ausreichende Kropfung am Ansatzdorn der Zange und die Anlage des Bohrlochs parietal, nicht, wie vielfach durchgefuhrt, in der dunneren Temporalschuppe.

The role of interventional radiology in the management of abnormally invasive placenta: a systematic review of current evidences

2020

Abnormally invasive placenta (AIP) is a potentially severe condition. To date, arterial embolization in women with postpartum hemorrhage due to AIP is the treatment option for which highest degrees of evidence are available. However, other techniques have been tested, including prophylactic catheter placement, balloon occlusion of the iliac arteries and abdominal aorta balloon occlusion. In this systematic review, we provide an overview of the currently reported interventional radiology procedures that are used for the treatment of postpartum hemorrhage due to AIP and suggest recommendations based on current evidences. Owing to a high rate of adverse events, prophylactic occlusion of intern…

A pouch in the cervix: a strange diagnosis

2016

Anechoic cervical lesions are uncommon findings which may entail diagnostic and, therefore, management difficulties. Chronic cervicitis, bulky nabothian cysts, adenomyomas, niches (cesarean scar defects), congenital malformations, and pseudo-neoplastic glandular cervical lesions often raise diagnostic dilemmas; they may also mimic malignant lesions [1–4]. Other anechoic images worth considering are those produced by cystic changes after cervical trauma, lacerations, or extremely rare false passages resulting from cervical dilatation [5]. Methods

The role of US examination in the management of acute abdomen.

2013

Acute abdomen is a medical emergency, in which there is sudden and severe pain in abdomen of recent onset with accompanying signs and symptoms that focus on an abdominal involvement. It can represent a wide spectrum of conditions, ranging from a benign and self-limiting disease to a surgical emergency. Nevertheless, only one quarter of patients who have previously been classified with an acute abdomen actually receive surgical treatment, so the clinical dilemma is if the patients need surgical treatment or not and, furthermore, in which cases the surgical option needs to be urgently adopted. Due to this reason a thorough and logical approach to the diagnosis of abdominal pain is necessary. …

Targetoid appearance on T2-weighted imaging and signs of tumor vascular involvement: diagnostic value for differentiating HCC from other primary live…

2021

To evaluate targetoid appearance on T2-weighted imaging and signs of tumor vascular involvement as potential new LI-RADS features for differentiating hepatocellular carcinoma (HCC) from other non-HCC primary liver carcinomas (PLCs). This IRB-approved, retrospective study was performed at two liver transplant centers. The final population included 375 patients with pathologically proven lesions imaged between 2007 and 2017 with contrast-enhanced CT or MRI. The cohort consisted of 165 intrahepatic cholangiocarcinomas and 74 combined hepatocellular-cholangiocarcinomas, with the addition of 136 HCCs for control. Two abdominal radiologists (R1; R2) independently reviewed the imaging studies (112…

Clinical indications for cardiac computed tomography. From the Working Group of the Cardiac Radiology Section of the Italian Society of Medical Radio…

2012

"\"La tomografia computerizzata del cuore (CCT) è diventata uno strumento efficace in differenti contesti clinici. Lo sviluppo della tecnologia ha portato ad una progressiva espansione delle indicazioni con una concomitante riduzione della dose di radiazioni necessaria per l’esecuzione dell’indagine. Ancora oggi sono pochi i documenti delle maggiori società scientifiche internazionali che si esprimono sulle effettive modalità di utilizzo e sulle indicazioni cliniche della CCT; in particolare mancano delle linee guida complete. Questo documento rispecchia la visione del gruppo di lavoro della Sezione di Cardio-Radiologia della Società Italiana di Radiologia Medica in merito alle indicazioni …

Eye lens equivalent dose in interventional neuroradiology based on OSL dosimetry

2016

Over the past years there has been an increase in the assessment of eye lens doses in interventional radiology procedures. This is due to the new recommendations of the International Commission on Radiological Protection (ICRP-2012 Publication 118) that proposes to reduce equivalent dose limit for the eye lens. The aim of this study is to make estimates of equivalent dose received by eye lens of the medical staff in interventional neuroradiology procedures. Consequently, this study presents an alternative for eye lens dosimetry. For this purpose nanoDot dosimeters based on optically stimulated luminescence (OSL) technology from Landauer Inc. product were used. The measurements obtained for …

Ultrasound-guided musculoskeletal interventional procedures around the shoulder

2021

Ultrasound is a fast, accessible, reliable, and radiation-free imaging modality routinely used to assess the soft tissues around the shoulder. It enables to identify a wide range of pathological conditions. Furthermore, most ultrasound-guided musculoskeletal interventional procedures around the shoulder produce better results in terms of accuracy and clinical efficacy than those performed in a blinded fashion. Indeed, intra-articular and peri-articular interventional procedures can be easily performed under continuous ultrasound monitoring to ensure the correct position of the needle and to deliver the medication to a specific target. Several technical approaches and medications can be used…
