    Description / Table of Contents: Résumé Les auteurs ont évalué l'angiographie par résonance magnétique (MRA) comme méthode d'imagerie possible de la v. rénale gauche. 25 patients présentant un anévrysme de l'aorte abdominale ont subi un scanner sans préparation et avec produit de contraste, et une angiographie par résonance magnétique en 2 dimensions (2D) en acquisition répétitive fondée sur le temps de passage (time of flight TOF). Les images obtenues par MRA ont été comparées au résultat du scanner, considéré comme la référence pour l'exploration vasculaire. L'angiographie par résonance magnétique a été réalisée avec un aimant de 1.5 T (Magnetom), en imagerie rapide avec état de précession libre (FISP) en séquence 2D (TR 40 ms, TE 10 ms, FA 18°). Les images ont été acquises dans les plans coronal et sagittal, respiration bloquée, et reconstruites selon les techniques de projection d'intensité maximale (MIP) et de MIP ciblée. Les images par MRA acquises dans le plan sagittal montrent correctement le trajet rétroaortique de la v. rénale gauche dans 6 cas. Dans le plan coronal, les reconstructions par MIP ciblée du trajet de la v. rénale gauche ont montré correctement son abouchement au niveau de la v. cave inférieure dans 5 cas, et au niveau de la v. iliaque gauche dans 1 cas. La MRA paraît être une technique d'imagerie vasculaire non invasive prometteuse, capable de montrer correctement le trajet et l'abouchement de la v. rénale gauche. Nous avons notamment remarqué que la v. rénale gauche pouvait être saisie en quelques secondes en utilisant seulement une vue panoramique générale (mode radio) avec une technique séquentielle TOF en deux dimensions dans le plan sagittal au niveau de l'aorte abdominale.
    Notes: Summary The authors evaluated magnetic resonance angiography (MRA) as a possible diagnostic method to image the left renal vein. Twenty-five patients with abdominal aortic aneurysm underwent both plain and contrast-enhanced CT, as well as two-dimensional (2D) sequential time of flight (TOF) MRA. MRA images were evaluated on the basis of the results of CT, taken as the “gold standard” for vessel demonstration. MRA was performed with a 1.5 T superconductive magnet (Magnetom), fast imaging with steady-state free precession (FISP) 2D sequence (TR 40 ms, TE 10 ms, FA 18°). Images were acquired in breath-hold on the coronal and sagittal plane and reconstructed according to maximum intensity projection (MIP) and targeted-MIP techniques. MRA images acquired on the sagittal plane correctly showed the retroaortic course on the left renal v. in six cases. On the coronal plane, targeted-MIP reconstructions for the course of the left renal v. correctly detected its outlet at the level of the inferior vena cava in five cases and of the left iliac v. in one case. MRA appears to be a promising noninvasive vascular imaging technique capable of correctly detecting the course and the outlet of the left renal v. We particularly noticed that the left renal v. can be imaged in a few seconds by using only one scout view with 2D sequential TOF technique on the sagittal plane at the level of the abdominal aorta.

    Notes: Abstract. The aim of this study was to compare high-resolution 2D TOF with high-resolution 3D TOF in the study of internal carotid artery disease. Sixty-four patients with clinical signs of cerebrovascular insufficiency were studied with a superconductive 1.5 T magnet using two techniques: 2D and 3D TOF. Digital subtraction angiography (DSA) was the gold standard. The 2D TOF technique was performed using the following parameters: TR/TE/FA/MA 49 ms/9 ms/60°/512 × 256; the 3D TOF was performed with the following parameters: TR/TE/FA/MA 50 ms/8 ms/20°/512 × 256. The 2D TOF agreed with DSA in 116 of 128 diagnostic judgments (90 %) and overestimated seven times. The 3D TOF technique agreed with DSA in 125 of 128 diagnostic judgments (97 %) with one overestimation and two underestimations. There was no statistically significant difference (P 〈 0.05) between the two different techniques. Our study confirms the high reliability of the methodology carried out with the high-resolution 2D and 3D technique.

    Notes: Abstract. Bronchioloalveolar carcinoma is a histologically distinct form of pulmonary adenocarcinoma representing an estimated 2–10 % of all primary lung cancers. Its varied appearances include focal masses, nodular patterns, and pneumonic and diffuse forms so that bronchioloalveolar carcinoma should be considered in the differential diagnosis of solitary or multiple pulmonary nodules and acute or chronic alveolar diseases. In this article we describe the different radiographic manifestations of bronchioloalveolar carcinoma with particular emphasis on CT findings and those signs that may help in identifying the lesion as bronchioloalveolar carcinoma.

    Notes: Abstract. This prospective study was aimed at comparing the diagnostic accuracy of magnetic resonance angiography (MRA) with colour-Doppler ultrasonography (colour-Doppler US) in the assessment of abdominal aortic aneurysms (AAA). Twenty patients with abdominal aortic aneurysms underwent MRA, colour-Doppler US, digital subtraction angiography (DSA) and CT. The MRA technique and colour-Doppler findings were compared with DSA as well as surgical and pathological findings, which were considered as the gold standard. In 6 patients who refused surgery, CT and DSA were considered as the gold standard. The MRA technique always correctly assessed the size and site of the aneurysms, the involvement of the renal and common iliac arteries, the course of the left renal vein, the thrombotic component and the calcifications. Colour-Doppler US always correctly assessed the size and site of the aneurysms, the thrombotic component and calcifications and the involvement of the iliac arteries. Our preliminary results suggest that MRA together with colour-Doppler US represents a valid alternative to invasive imaging in the assessment of AAA.

    Notes: Abstract. Thoracic lymphomas, which are very common especially in Hodgkin's disease patients, are characterised by enlargement of mediastinal lymph nodes, parenchymal abnormalities, and pleural, pericardial and chest wall involvement. The use of several imaging techniques has been proposed in order to assess the extent of the disease correctly and to plan therapy. The most relevant results in this field, especially those using computed tomography (CT), magnetic resonance imaging (MRI) and gallium scanning, are summarised in this review. Presently CT is widely and successfully used in staging patients, whereas MRI seems to be preferable, as a second-step technique, if pericardial, pleural and chest wall involvement are suspected. The role of gallium scanning is limited in the staging, although it could be relevant in the follow-up of treated patients.
