Also included are chapters covering patient preparation and tagging, performing and reporting virtual colonoscopy, viewing methods, MR colonography, and computer aided detection. The second part of the text presents an atlas of high-resolution images with detailed explanations of teaching points, covering normal anatomy; sessile, pedunculated, diminutive and flat lesions; masses; stool and diverticula; and common pitfalls. Atlas of Virtual Colonoscopy is a valuable resource for all radiologists and gastroenterologists interested in learning the fundamentals of this exciting technique.

The aim of this book is fourfold: to describe the basic principles of Dual Energy CT (DECT) imaging, to explain how post-processing is utilized, to critically appraise the strengths and weaknesses of the technique in oncologic imaging, and above all, to demonstrate the contribution of DECT in the management of oncologic patients. Information is provided on the practice and interpretation of DECT and its impact on clinical decision making in a variety of oncological settings, including tumors of the head and neck, lung, liver, pancreas, gastrointestinal system, kidney, and musculoskeletal system.

DECT is an innovative imaging technique in which the application of two distinct energy settings provides a transition from density-based image to spectral imaging.

As detailed in this book, DECT acquisition allows the simultaneous generation of multiple datasets which enable the radiologist to address varied diagnostic problems in oncologic imaging using a multiparametric approach, having clear advantages in tumor detection, lesion characterization and evaluation of treatment response.

The fourth edition of this well-received book offers a comprehensive update on recent developments and trends in the clinical and scientific applications of multislice computed tomography. Following an initial section on the most significant current technical aspects and issues, detailed information is provided on a comprehensive range of diagnostic applications. Imaging of the head and neck, the cardiovascular system, the abdomen, and the lungs is covered in depth, describing the application of multislice CT in a variety of tumors and other pathologies. Emerging fields such as pediatric imaging and CT-guided interventions are fully addressed, and emergency CT is also covered. Radiation exposure, dual-energy imaging, contrast enhancement, image postprocessing, CT perfusion imaging, and CT angiography all receive close attention. The new edition has been comprehensively revised and complemented by contributions from highly experienced and well-known authors who offer diverse perspectives, highlighting the possibilities offered by the most modern multidetector CT systems. This book will be particularly useful for general users of CT systems who wish to upgrade and enhance not only their machines but also their knowledge.

This book adopts a multidisciplinary approach to examine in detail a range of interesting new concepts in the diagnosis and therapy of pancreatic adenocarcinoma. It is divided into three parts. The first part provides an epidemiological and clinical overview of the disease, followed by an update on pathological findings, including new discoveries in the area of molecular biology. The second part, on diagnosis, offers detailed and comprehensive information on the advantages and disadvantages of different imaging techniques, including nuclear medicine and endoscopic ultrasound. The concluding part gives a panoramic overview of the various therapeutic options, from surgery to chemotherapy and palliative approaches based on interventional endoscopy and radiology. This book will be a valuable source of information for clinicians involved in the management of pancreatic adenocarcinoma and for all who are interested in updating their knowledge of the disease, including fellows and senior residents.

Questo volume si articola in quattro sezioni, che spaziano dai concetti fondamentali di epidemiologia ed etiopatogenesi del cancro colo-rettale sino alla trattazione della tecnica di esame (pulizia intestinale, preparazione del paziente e altri aspetti pratici, protocolli di studio e considerazioni dosimetriche, complicanze, analisi delle immagini: 2D vs 3D, software di visualizzazione, sistemi di diagnosi assistita, refertazione) e all''analisi critica della letteratura, con particolare riguardo alle indicazioni cliniche condivise dalla comunità scientifica internazionale. E'' inclusa, inoltre, un''ampia casistica ragionata (anatomia, tumori, polipi, casi complessi). Il testo intende fornire al radiologo, specializzato nello studio del colon, un aggiornamento completo su questa innovativa tecnica che può oggi validamente competere con la colonscopia ottica anche in ambito di screening del cancro colo-rettale.

La TC spirale multistrato (TCMS) è una metodica cardine nella diagnostica addominale, in grado di offrire un contributo spesso determinante per l’inquadramento clinico del paziente. Una diagnosi accurata non può, comunque, prescindere da una rigorosa tecnica di esame, in continua evoluzione parallelamente allo sviluppo delle apparecchiature. Attraverso la presentazione di casi riguardanti le principali patologie addominali, il volume rappresenta per il Radiologo generale e per lo Specializzando una guida snella in grado di supportarli nelle decisioni riguardanti l’ottimizzazione dei protocolli di studio in relazione al quesito clinico.

L’angiografia con TC spirale multistrato è oggi una metodica fondamentale nella diagnostica vascolare non invasiva in pressoché tutti i distretti anatomici. La facilità e, soprattutto, la rapidità di esecuzione la rendono anche essenziale nei casi di urgenza ed emergenza. La qualità diagnostica dell’esame, e la conseguente accuratezza della diagnosi, sono il risultato di un’ottimizzazione della tecnica di studio e, in particolare, del protocollo di iniezione endovenosa del mezzo di contrasto iodato.

Mediante la presentazione di casi esplicativi riguardanti i differenti distretti vascolari, il volume intende fornire al Radiologo generale e allo Specializzando una guida ai principali protocolli di studio da mettere in atto al fine di ottimizzare la qualità dell’esame e, conseguentemente, facilitare il processo diagnostico.

L''avvento delle apparecchiature TC spirale multistrato, e in particolare di quelle a 64 strati e oltre, ha rivoluzionato l''approccio diagnostico allo studio del torace, sia per quanto riguarda la patologia polmonare, delle vie aeree e del mediastino, sia per lo studio del cuore e dei grossi vasi. Per ottenere una diagnosi accurata è, però, necessario un addestramento specifico e una profonda conoscenza dei protocolli di studio, spesso da adattare in relazione alla particolare situazione clinica del Paziente, e tenendo sempre in considerazione la dose di radiazioni somministrata. Il presente volume è stato pensato proprio tenendo conto di questa complessità, con il duplice scopo di fornire al Radiologo e al giovane Specializzando una serie di brevi nozioni teoriche, necessarie per impostare correttamente il protocollo di studio, e una casistica clinica riportante le principali patologie che più di frequente possono essere incontrate nella pratica quotidiana.

Multidetector-row computed tomography (MDCT) has become a fundamental imaging technique for the study of many anatomical districts in different clinical situations, as it provides a fast, reliable, and accurate simultaneous evaluation of different organs, including parenchyma, hollow viscera, vessels, and bony structures. It has also equipped the radiologist with the ability to explore areas that in the last decade were largely ignored by CT, especially the coronary arteries and the colon, and to limit invasive diagnostic tests (e.g., catheter angiography) to those cases in which interventional procedures are required.

The examination quality and the consequent diagnostic accuracy of MDCT are the results of an optimized study technique, which nonetheless needs to be adapted to the particular clinical situation of the patient, while bearing in mind the radiation exposure. Another fundamental parameter in the optimization of MDCT is the protocol for the intravenous injection of iodinated contrast material; in these studies, multiple variables, some modifiable by the operator and others patient-dependent, must be considered based on the aims of maximizing arterial and venous enhancements whilst minimizing the dose of iodine injected, saving money, and increasing patient safety.

Through the presentation of cases addressing different anatomical regions and various clinical indications, including emergency and neuro-imaging, this volume seeks to provide the general radiologist and trainee specialist with a guide to the main study protocols to be implemented in order to optimize examination quality and, consequently, facilitate the diagnostic process.
