Abstract

Abstract: Purpose: To assess the additional value of multiplanar reformations (MPR) in comparison with axial images alone for location of the transition zone in CT of mechanical small-bowel obstruction (SBO). Materials and methods: Sixty-nine consecutive patients with mechanical SBO underwent 16-slice multi detector row CT (MDCT). The gold standard for the precise location of the transition zone was established by two experienced abdominal radiologists, unblinded to clinical and surgical reports, reviewing all CT examinations. On a workstation, two blinded readers independently located the transition zone using first axial slices alone and then 1 month later MPR (axial, coronal, sagittal and oblique views) according to a three-point confidence scale. Diagnostic accuracy and mean confidence score were evaluated for both the transverse and multiplanar data sets. Results: Accuracy of transition zone location for reader 1 and reader 2 was 86% and 84% with axial slices alone, and by using MPR 93% (significant: P = 0.03) and 90% (not significant: P = 0.08), respectively. Mean confidence score was significantly increased for both readers using MPR: 0.3 higher (P = 0.0001) and 0.37 higher (P = 0.0001) respectively. Conclusion: MPR can increase both accuracy and confidence in the location of the transition zone in CT of SBO.

4. Multidetector CT Angiography in Acute Gastrointestinal Bleeding: Why, When, and How

Author

Geffroy, Yann, Rodallec, Mathieu H., Boulay-Coletta, Isabelle, Jullès, Marie-Christine, Ridereau-Zins, Catherine, and Zins, Marc

Abstract

Acute gastrointestinal (GI) bleeding remains an important cause of emergency hospital admissions, with substantial related morbidity and mortality. Bleeding may relate to the upper or lower GI tract, with the dividing anatomic landmark between these two regions being the ligament of Treitz. The widespread availability of endoscopic equipment has had an important effect on the rapid identification and treatment of the bleeding source. However, the choice of upper or lower GI endoscopy is largely dictated by the clinical presentation, which in many cases proves misleading. Furthermore, there remains a large group of patients with negative endoscopic results or failed endoscopy, in whom additional techniques are required to identify the source of GI bleeding. Multidetector computed tomography (CT) with its speed, resolution, multiplanar techniques, and angiographic capabilities allows excellent visualization of both the small and large bowel. Multiphasic multidetector CT allows direct demonstration of bleeding into the bowel and is helpful in the acute setting for visualization of the bleeding source and its characterization. Thus, multidetector CT angiography provides a time-efficient method for directing and planning therapy for patients with acute GI bleeding. The additional information provided by multidetector CT angiography before attempts at therapeutic angiographic procedures leads to faster selective catheterization of bleeding vessels, thereby facilitating embolization.

5. Cerebral Venous Thrombosis and Multidetector CT Angiography: Tips and Tricks

Author

Rodallec, Mathieu H., Krainik, Alexandre, Feydy, Antoine, Hélias, Annick, Colombani, Jean-Michel, Jullès, Marie-Christine, Marteau, Véronique, and Zins, Marc

Abstract

Because of the great diversity of clinical features, its unforeseeable evolution, and a small proportion of cases that will worsen in the acute phase, cerebral venous thrombosis must be diagnosed as early as possible so that specific treatment can be started, typically transcatheter thrombolysis or systemic anticoagulation. Unenhanced computed tomography (CT) is usually the first imaging study performed on an emergency basis. Unenhanced CT allows detection of ischemic changes related to venous insufficiency and sometimes demonstrates a hyperattenuating thrombosed dural sinus or vein. Helical multidetector CT venography with bolus power injection of contrast material and combined use of two-dimensional and three-dimensional reformations (maximum intensity projection, integral display, and volume rendering) provides exquisite anatomic detail of the deep and superficial intracranial venous system and can demonstrate filling defects. However, common variants of the sinovenous system should not be mistaken for sinus thrombosis. A comprehensive diagnostic approach facilitates imaging of cerebral venous thrombosis with multidetector CT. © RSNA, 2006

7. Imagerie conventionnelle dans l’épilepsie

Author

Mellerio, Charles, Roca, Pauline, Chassoux, Francine, Devaux, Bertrand, Rodallec, Mathieu, Meder, Jean François, and Oppenheim, Catherine

Abstract

Le rôle de l’imagerie dans le bilan de la maladie épileptique est prépondérant, en particulier dans le bilan préchirurgical des épilepsies résistantes au traitement médicamenteux, afin de trouver une étiologie et de planifier l’étendue du geste chirurgical. La première cause d’épilepsie réfractaire opérée est la sclérose de l’hippocampe, suivi par les causes tumorales et les malformations du développement cortical (en particulier les dysplasies corticales focales). L’anomalie causale est parfois subtile et le protocole d’acquisition (séquences, plan d’étude, reformatage) doit être d’autant plus rigoureux et adapté au contexte clinique et électro-clinique (crise temporale vs extratemporale ? EEG localisateur ?). L’optimisation des séquences (3D-FLAIR, double inversion récupération, susceptibilité) trouve particulièrement son intérêt. La reconstruction multiplanaire et surfacique est également fondamentale pour dépister de petites modifications corticales ou sulcales. L’injection n’apporte le plus souvent pas d’information, hormis dans le cas des causes tumorales épileptogènes (DNT, gangliogliome).
