1037 The Reconstruction of 3D Contrast-Enhanced Ultrasonography in the Evaluation of Vascular Complications in Transplanted Liver Hong Han, Zhongshan Hospital Affiliated Fudan Unviersity, China Bei-Jian Huang, China Wen-Ping Wang, Ultrasound Department of Zhongshan Hospital Affiliated Fudan University, China Hong Ding, Department of Ultrasound, China Objective: To evaluate the value of three dimensional contrast-enhanced ultrasonography (3D-CEUS) in evaluating hepatic vascular patency after liver transplantation. Methods: Twenty patients suspected of hepatic vascular complications after liver transplantation were examined by two dimensional contrastenhanced ultrasonography (2D-CEUS) and 3D-CEUS. Contrast agent was SonoVue and low mechanical index harmonic contrast-enhanced ultrasonography was performed. According to the visualization of the peripheral branches of the hepatic artery, the 3D images were evaluated as score 1 to 4 (score 1, only common hepatic artery; score 2, left or right hepatic artery; score 3, segmental branches of hepatic artery; score 4, subsegmental branches of hepatic artery). The visualization of hepatic artery branches was compared between 2D-CEUS and 3D-CEUS. Results: The 3D hepatic artery tree structures were visualized in 17 cases with patent hepatic arteries by 3D-CEUS. The score of peripheral branches of hepatic artery was (2.61⫾0.50) by 3D-CEUS, superior to the (3.61⫾0.50) by 2D-CEUS(P⫽0.000). 1 hepatic artery stenosis, 1 portal vein stenosis and 1 inferior vein stenosis were all clearly revealed by 3D-CEUS after liver transplantation. Conclusions: 3D-CEUS is a useful technique to visualize the hepatic artery tree and can provide more diagnostic information than 2DCEUS. 3D-CEUS is a beneficial complement of 2D-CEUS in the diagnosis of hepatic vascular complications after liver transplantation.
3D Sonographic Measurements Using a Matrix Array Transducer to Investigate the Relationship between Total Renal Volume and Renal Function Hyun Cheol Kim, Department of Radiology, East-West Neo Medical Center, College of Medicine, Kyung Hee University, Korea Dal Mo Yang, Department of Radiology, East-West Neo Medical Center, College of Medicine, Kyung Hee University, Korea Wook Jin, Department of Radiology, East-West Neo Medical Center, College of Medicine, Kyung Hee University, Korea Objective: To determine the reproducibility of three-dimensional (3D) ultrasonography (US) using a matrix array transducer (3D US-MAT) as a means of measuring renal volume and to investigate correlations between renal volume and renal function. Methods: Institutional review board approval was obtained, and all patients gave informed consent. One hundred-twenty patients, comprised of 20 consecutive patients with each of the five stages of chronic renal disease and 20 normal volunteers (stage 0), were enrolled in this study. Individual renal volumes were determined using the ellipsoid formula from twodimensional (2D US) data, and using the stacked ellipse method from 3D US-MAT data by two independent observers. Volume measurement reproducibilities were evaluated for both of these methods. After normalizing total renal volumes (TRV), correlations between normalized TRVs (nTRVs) determined using both methods and estimated glomerular filtration rates (eGFR) were evaluated. Differences between nTRVs at each stage of chronic renal disease were also evaluated. Results: The reproducibility of 3D US-MAT was greater than that of 2D US, and the correlation coefficient between nTRVs by 3D US-MAT and eGFRs for two observers (r⫽0.809 and 0.813; p⬍0.001) was better than that between nTRVs by 2D US and eGFRs (r⫽0.696 and 0.715; p⬍0.001). Mean nTRVs in both stage 0 and 1 were significantly greater than those in other stages (p⬍0.001), and Mean nTRV of stage 5 was significantly lower than those in other stages ( p⬍0.001). Conclusions: 3D US-MAT offers a reliable means of measuring renal volumes during evaluations of patient with reduced renal function.

Abstracts Purpose: Affections of the orbit and eye are easily described by means of computed tomography (CT) and magnetic resonance (MR) but there are some cases where ultrasound can be diriment or very helpful. The purpose of our work is to demonstrate the role of HR-US, 3D and CEUS in the assessment of the anterior eye, the vitreous body and the eyebulb. Methods and Materials: 131 patients with a suspect affection of the eye and/or of the orbit have been assessed with HR-US. Among these, 13 patients underwent also to a 3D examination and 11 underwent also to a CEUS. Moreover, 18 patients underwent a CT and 10 a MR. Results: We detected 66 traumatic lesions: among these, there were 6 lesions of the anterior chamber, 34 lesions of the vitreous body, 11 lesions of the eye membranes, 7 lesions of back-eyebulb soft tissues, 9 retinal separations and 7 coroid separations. Furthermore, we detected 2 coroid melanoma, 3 back-eyebulb intraconal tumors, 4 orbital extraconal tumors and 2 arterovenous malformation. Dysthyroid orbitopathy was excluded from our study. Conclusions: HR-US was highly sensitive in the detection of traumatic and non-traumatic lesions of the eyebulb. On the other hand, HR-US was not efficient in the assessment of the lesions of the orbital wall. The use of 3D module has increased the diagnostic value of HR-US. CEUS is helpful in the differential diagnosis of retinal separations and bulbar tumor, in the therapeutic program of coroid melanoma and in the evaluation of orbital neoformation vascularization. 1041 The Value of 3D Ultrasonography (3DUS) of Achilles Tendon in Comparison with Standard 2D US Imaging Malgorzata Serafin-Krol, Imaging Dept.

IInd Medical Faculty, Warsaw Medical University, Poland Jaroslaw Deszczynski, 2 Dept. of Orthopaedics and Rehabilitation, Warsaw Medical University, Poland Objective: 1. To compare accuracy of 3DUS with 2DUS in assessment of Achilles tendon 2. To find out if additional pathology on 3DUS can be found. Material and Method: Studied group consisted of 10 healthy tendons and 38 with pathology. Ultrasonography was performed with Voluson 730 Expert (GE) with linear probe 5-16 MHz and linear 5-16 MHz volumetric probe. US of all Achilles tendons was performed in transverse and longitudinal scans on 2D. On 3DUS transverse, longitudinal and coronal third Z plane were studied. In all tendons width and thickness of a tendon and pathological lesions were assessed. The results of measurements on 2D and 3D images were compared. The images were analyzed regarding an appearance, contours, size and localization of a lesion. The lesions were visualized on 3D reconstructed images. Results: Significant differences in measurement of tendon size were not found. Evaluation of size of the smaller lesions did not differ significantly.In larger ones differences were greater but not statistically significant. There were problems with correct assessment of lesion size when it occupied more than two successive volume scans. Additional information were obtained in 19 of 38 (50%) mainly smaller pathologies due to Z-plain. The 3D reconstructed model helped in understanding anatomical relations of injured fibers. Conclusions: 1. 3DUS imaging is reliable and accurate as 2DUS. 2. In smaller lesions, borders and type of the lesion are better visualized on additional third plane. 3. It is more difficult to assess larger lesions. grant MNiI 1034/P01/2006/30

The aim of the study was to check the usefulness of novel 3D endovaginal ultrasound (EVUS) in the imaging of bladder neck and urethral morphology in continent and incontinent women. Methods and Materials: Sixty two females mean age 45 years (range: 19-71) underwent 3D-EVUS. Twenty of them (32%) were continent, whilst 42 (68%) suffered from stress urinary incontinence (SUI). The EVUS examinations were performed using an ultrasound system (Profocus, B-K Medical) with a 9-12MHz, rotational transducer with a built-in 3D automated acquisition system and perpendicular beam formation. The 3D acquisition was performed in B-mode and with Colour Doppler mode, starting from bladder and ending beyond the external orifice of the urethra. The evaluation of the urethral complex was also performed post examination using stored data. Results: In all patients a novel 3D EVUS enabled precise visualization of the urethral morphology. Bladder neck was clearly seen in all patients, so that it was possible to perform the measurements of its thickness. Typical 3-layer wall of the urethra was also easily visible. Moreover, it was possible to depict the rhabdosphincter muscle and observe its variability among the examined subjects. Colour Doppler showed vascular patterns. Conclusion: A novel 3D-endovaginal ultrasound is very valuable imagining technique in the assessment of urethral complex and bladder neck morphology in females and may become a very important tool in early diagnostics of SUI. 1043 The Comparison of the Morphology of Bladder Neck in Continent and Incontinent Women with the use of a Novel 3DEndovaginal Ultrasound Magdalena M Wozniak, Radiology Department, Children’s Hospital of Medical University of Lublin, Poland Aleksandra Stankiewicz, Radiology Department, Children’s Hospital of Medical University of Lublin, Poland Michal Bogusiewicz, Second Department of Gynecology, Medical University of Lublin, Poland Andrzej Pawel Weczorek, Radiology Department, Children’s Hospital of Medical University of Lublin, Poland Tomasz Rechberger, Second Department of Gynecology, Medical University of Lublin, Poland Purpose: The aim of the study was comparison of the morphology of bladder neck (BN) in continent and incontinent women with the use of a novel 3D-endovaginal ultrasound (EVUS).
