Atlas of Virtual Colonoscopy thoroughly revises and updates Abraham Dachman's bestselling first edition. Joined in this edition by co-editor Andrea Laghi, Dr. Dachman has expanded the focus of the text to cover fundamental topics of this rapidly evolving technology, including the history of virtual colonoscopy, a review of clinical trial data from throughout the world, and a presentation of clinical background information. 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.

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 comunita 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 puo oggi validamente competere con la colonscopia ottica anche in ambito di screening del cancro colo-rettale.
