Una chiacchierata informale (ma seria) sulla RM Ciao, eccoci qua. Prima che inizi a sfogliare le prossime pagine, permettici di presentarci, così sai con chi avrai a che fare per tutto il libro. M Io sono Manuel, un medico radiologo di campagna, conosciuto sui social come @the_beachdoctor. Nella pratica sono “quello che cerca disperatamente di spiegare la radiologia con un linguaggio comprensibile”. Da anni sono su Instagram e YouTube con un’idea fissa: trasformare la diagnostica per immagini da “cose che vediamo senza capirle” in “immagini che capiamo per farci davvero la diagnostica”. Molti “radiocuccioli” (così chiamo gli specializzandi in radiologia) mi scrivono dicendo che non sanno nulla di RM, che non hanno la minima idea di come si arrivi da un protone che gira all’immagine che vedono sul monitor. E la verità, quella un po’ scomoda, è che tantissimi medici radiologi non ne hanno proprio idea. Per arrivare a capire io stesso queste cose, ho dovuto sudare parecchio. Ma dopo aver risposto per anni a centinaia di domande mi sono accorto che ancora mi sfuggivano alcuni passaggi. G Ed io sono Giovanni, un tecnico di radiologia che lavora nello stesso ospedale di Manuel. Ho un approccio forse più analitico, più tecnico, a volte anche più “accademico” – ma non meno appassionato. Per lungo tempo mi sono occupato di formazione universitaria in ambito RM ed il mio obiettivo è sempre stato uno: aiutare i colleghi e gli studenti a costruire un pensiero solido, capace di andare oltre la semplice esecuzione dei protocolli. Dietro ogni parametro c’è un principio fisico, e dietro ogni immagine c’è una scelta tecnica consapevole e questa cosa mi affascina molto. Così un giorno con Manuel ci siamo guardati e ci siamo detti: perché non unire le forze? M Abbiamo preso carta e penna e ci siamo seduti attorno a un tavolo. Ci siamo immaginati tutti voi lì con noi, in un bar, davanti a un lungo caffè. Abbiamo iniziato a raccontarci a vicenda la risonanza: io spiegavo con le mie metafore un po’ surreali e Giovanni, con il suo sorriso serafico, interveniva a bacchettarmi ogni volta che semplificavo troppo. Lui, poi, a volte si lanciava in spiegazioni super-accademiche, e io mi mettevo subito a fare da traduttore simultaneo, trasformando il suo “medichese” in lingua potabile, umana, comprensibile da chiunque. G Il risultato è proprio il libro che hai in mano. Chiariamolo subito, non abbiamo la pretesa di dire tutto, ma abbiamo l’ambizione di dire bene le cose che contano. Questo libro nasce per semplificare senza banalizzare, per avvicinare senza perdere profondità. Non è un testo scientifico in senso stretto: non troverai riferimenti bibliografici puntuali, modelli matematici rigorosi o analisi ultra-specialistiche. Troverai invece una narrazione tecnica, chiara e concreta, che si prende la libertà di essere accessibile. Che punta a far ragionare, più che a dimostrare.  M Per questo si chiama “Il tuo primo libro di RM”, perché sappiamo già che se vorrai diventare un vero esperto, ce ne dovranno essere sicuramente un secondo, un terzo, forse anche di più, con altri autori e altri linguaggi, che approfondiranno tutto ciò che qui abbiamo soltanto introdotto. Perché per quanto i contenuti digitali siano uno strumento prezioso, poiché veloci, accattivanti e capaci di accendere la curiosità, restano spesso frammentati: e te lo dice uno che, sui social, di radiologia parla spesso. Un buon libro, invece, ha ancora oggi un potere unico: ti accompagna con ordine, costruisce una visione completa, ti costringe a fermarti, a ragionare. È lì che avviene la vera formazione profonda. G I capitoli si aprono spesso con una scena, una battuta, un’immagine mentale. Non è un vezzo: è un modo per entrare nel cuore dei concetti senza perdere l’orientamento. Si parte dalle basi, ma si arriva lontano: il libro è costruito con una struttura graduale, dove ogni sezione aggiunge un tassello, dalla fisica elementare ai protocolli clinici, dalle sequenze fondamentali alle tecniche più avanzate. Il libro è strutturato in cinque sezioni, ognuna con un’identità precisa:• I fondamentali, per costruire la base: cos’è un voxel, come si orientano i protoni, cosa fa davvero una bobina.• Le sequenze di base, per capire le dinamiche delle acquisizioni più comuni, i loro pregi, i loro limiti.• Le strategie per ridurre i tempi, dove si entra nel vivo della pratica clinica, bilanciando qualità e velocità.• Le applicazioni speciali, in cui la risonanza mostra il suo lato più creativo e potente.• I consigli pratici, per chi lavora in RM ogni giorno e cerca strumenti semplici ma efficaci per migliorare il proprio approccio. M Durante la lettura, capiteranno momenti in cui ti sentirai un po’ scoraggiato: è normalissimo. Alcuni passaggi sono densi di contenuti e richiederanno più di una lettura. Non averne a male. Chiudi il libro, prenditi una pausa, fai un giro e poi riprendilo con calma. Per quanto il nostro tono sia leggero, i concetti che trattiamo restano complessi e meritano il tempo che serve per assimilarli davvero. Vedrai però che alla fine della lettura tutto avrà trovato il suo posto. Dopo anni di nebbia mentale davanti alla RM (pensa al meme che raffigura una donna evidentemente confusa con intorno tutte quelle formule matematiche), finalmente sentirai che tutto ha un senso, una logica, una chiarezza che non avevi mai trovato prima. Allora, che ne dici? Ci lanciamo insieme in questa lunga chiacchierata davanti a un caffè al bar?  Manuel e Giovanni

The daily analysis of whole-body MRI datasets uncovers many incidental findings, which are discussed by an interdisciplinary advisory board of physicians. This book provides a systematic overview of these incidental findings with the aid of approximately 240 high-quality images.

Chapters on technical and ethical issues are also included. It is hoped that this book will assist other diagnosticians in deciding how to handle the most common incidental findings encountered when performing whole-body MRI.

The idea of using the enormous potential of magnetic resonance imaging (MRI) not only for diagnostic but also for interventional purposes may seem obvious, but it took major efforts by engineers, physicists, and clinicians to come up with dedicated interventional techniques and scanners, and improvements are still ongoing. Since the inception of interventional MRI in the mid-1990s, the numbers of settings, techniques, and clinical applications have increased dramatically. This state of the art book covers all aspects of interventional MRI. The more technical contributions offer an overview of the fundamental ideas and concepts and present the available instrumentation. The richly illustrated clinical contributions, ranging from MRI-guided biopsies to completely MRI-controlled therapies in various body regions, provide detailed information on established and emerging applications and identify future trends and challenges.
