Full textThe purpose of this thesis was to evaluate the diagnostic potential of a new ultrasound contrast agent,SonazoidTM, intended for use in patients with suspicion of prostate cancer.
The sonographic appearance of normal prostatic vascularity in dogs was evaluated before and after injection of Sonazoid,using different Doppler flow detection modes.The use of Sonazoid significantly improved the visibility of the vascular pattern in normal dog prostate,both with colour and power Doppler imaging.There was a significant difference in the depiction of blood flow in the prostate between the two imaging modalities,showing the power Doppler superior to colour Doppler imaging.The contrast revealed a radial,spoke-like intraprostatic pattern,not seen prior to contrast injection.
Different ultrasound imaging modalities were tested in a small group of young healthy male volunteers to evaluate the visibility of the normal prostate blood flow with and without Sonazoid.
The ultrasound contrast agent improved the visibility of the normal human prostate vascular anatomy for both colour and power Doppler imaging.Again,the improvement was significantly better for power Doppler than for colour Doppler imaging.Using fundamental B-mode,there was no major difference in the ultrasound appearance of the prost ate vascular it y before and after i njection of Sonazoid.Cont rast dynamic st udies of blood flow wit hi n t he normal gland showed a filling from the periphery towards the centre in all subjects,demonstrating a symmetric, radial vascular pattern.
A canine prostate model was used to investigate if Sonazoid,could improve the visualisation of prostatic vessels to better delineate areas on normal and decreased blood flow.Both 2D and 3D power Doppler imaging was performed in this study.The visibility of the prostate blood flow improved significantly following injection of Sonazoid for both 2D and 3D power Doppler imaging.There was,however,no major difference in depicting the vascularity using 2D and 3D imaging.After injection of Sonazoid,a disturbance of the radial vascular pattern and a lack of blood flow symmetry between the two prostate lobes were possible to identify.The added information gained by injection of Sonazoid made it possible to identify areas of decreased blood flow not seen prior to contrast injection.
The vascular pattern of lesions,identified with B-mode imaging in patients with suspicion of prostate cancer,was studied,using Sonazoid.Contrast dynamic inflow in the lesions,compared to the adjacent tissue was investigated in the same study.Prostate cancer lesions appeared hypervasuclar prior to ultrasound contrast agent.Three of six cancer lesions changed from hypervascular to marked hypervascular following injection of Sonazoid,a finding that might be interpreted as a higher level of confidence.None of the non-cancer lesions were assessed as hypervascular after Sonazoid injection,a possible increased value of a negative finding.Four of the cancer lesions enhanced earlier compared to the surrounding prostate tissue,following ultrasound contrast injection.The results indicate that changes in vascular architecture,e.g.induction of angiogenesis by tumour cells,can be observed by ultrasonographically determining the inflow pattern of an intravenously injected ultrasound contrast agent.

Full textO estudo busca verificar a aplicabilidade de uma nova tÃcnica utilizando o Ultrassom trans-vaginal / trans-retal tridimensional dinÃmica como um mÃtodo diagnÃstico alternativo na avaliaÃÃo da evacuaÃÃo obstruÃda, comparando com a Ecodefecografia. Trata-se de um estudo prospectivo e comparativo, envolvendo pacientes do sexto feminino, com evacuaÃÃo obstruÃda e escore mÃdio de constipaÃÃo de Wexner acima de 6. Todas as pacientes foram submetidas ao exame ultrassonogrÃfico tridimensional dinÃmico por duas tÃcnicas distintas para identificar as disfunÃÃes responsÃveis pela defecaÃÃo obstruÃda. A Ecodefecografia foi utilizada como mÃtodo padrÃo na avaliaÃÃo comparativa da tÃcnica de Ultrassom combinado transvaginal/transretal tridimensional dinÃmica. ApÃs a introduÃÃo de 120 mL de gel na ampola retal, utilizou-se o acesso transvaginal para avaliar o Ãngulo anorretal em repouso e durante o esforÃo evacuatÃrio para identificar o relaxamento ou contraÃÃo paradoxal do mÃsculo Puborretal (Anismus). Utilizando o acesso transretal avaliou-se a presenÃa de Retocele nos diferentes tamanhos, IntussuscepÃÃo e Enterocele / Sigmoidocele durante o esforÃo evacuatÃrio. Os achados foram comparados entre si. A anÃlise estatÃstica foi realizada utilizando o test t de Student e o Coeficiente de correlaÃÃo Lee Kappa. Calculou-se a eficÃcia, sensibilidade, especificidade, valor preditivo positivo, valor preditivo negativo da tÃcnica do Ultrassom combinado transvaginal e transretal para identificaÃÃo de cada disfunÃÃo. Foram incluÃdas 33 pacientes do sexo feminino, idade mÃdia 48 anos, escore mÃdio de constipaÃÃo de Wexner de 10 (7 - 14). Houve substancial concordÃncia entre os dois exames para identificaÃÃo de Anismus e relaxamento normal (K=0.683). Houve reduÃÃo significante do Ãngulo anorretal em 19 pacientes submetidas a Ecodefecografia (84.79 Â Â 1.008 x 80.11Â Â 1.725), com variaÃÃo mÃdia de 5Â ( Â4,738 ) e em 17 pacientes avaliadas pelo Ultrassom transvaginal / transretal (120.5Â Â 2.378 x 109.6Â Â 3.449), com variaÃÃo mÃdia de 10,82ÂÂ8,164. A diferenÃa entre os Ãngulos foi significantemente maior nas pacientes avaliadas pelo Ultrassom transvaginal / transretal quando comparada com a Ecodefecografia (15.45Â Â 1.539 x 7.182Â Â 0.9804) (p=0,0001). Foi identificada Retocele em 27 pacientes e ausÃncia em 6 em ambas as tÃcnicas utilizadas, demonstrando Ãndice de concordÃncia quase perfeito (K=1.0). Doze pacientes apresentaram Retocele grau III, 9 grau II e 3 grau I em ambas as tÃcnicas utilizadas, demonstrando um Ãndice de concordÃncia quase perfeito para os diferentes graus da Retocele (K= 0.812) (K=0.857) (K= 0.841). Somente 3 pacientes foram discordantes entre os dois mÃtodos, sendo duas com grau III na Ecodefecografia e grau I e II no ultrassom transvaginal / transretal. Uma outra com grau II na Ecodefecografia e grau III no Ultrassom transvaginal / transretal. Comparando os dois mÃtodos, nÃo houve diferenÃa estatisticamente significante com relaÃÃo ao grau da Retocele (1,076Â0,6838 x 1,139Â0,7267) (p=0,7153). Houve um Ãndice de concordÃncia quase perfeito na identificaÃÃo de IntussucepÃÃo retal (K= 0.914) e Enterocele/Sigmoidocele (K= 0.659). Foram demonstrados valores acima de 87,5% de eficÃcia, sensibilidade, especificidade, valor preditivo positivo, valor preditivo negativo para cada disfunÃÃo avaliada. Conclui-se que a tÃcnica utilizando Ultrassom transretal / transvaginal tridimensional dinÃmica apresenta elevado Ãndice de concordÃncia com a Ecodefecografia, podendo ser utilizada como mÃtodo alternativo para avaliaÃÃo de pacientes portadoras de sintomas de evacuaÃÃo obstruÃda.

Prostate cancer is the most common male malignancy amongst black males in South Africa and the second commonest amongst white males (1,2). Prostate biopsy, via the rectum, is an essential part of diagnosing and treating this disease. Traditionally needle biopsies of the prostate were performed blindly by digital palpation of the gland per rectum.
