Rezumat
Performantele ecografiei in mod B sunt relativ limitate în descrierea morfologica a leziunilor ovariene. Studii realizate pe modele animale au demostrat capacitatea substantelor de contrast de tip microbule în detectarea neoangiogenezei tumorale.
Evaluarea fluxului sangvin prin metode ecografice Doppler permite obtinerea de argumente care ne orienteaza spre o patologie maligna, dar raman insuficiente, asa încat, ecografia cu contrast ramane o tehnica alternativa pentru evaluare microvascularizatiei tumorale. Astfel cu ajutorul substantelor de contrast putem face diferentierea dintre o leziune maligna ovariana si una benigna ramanand o tehnica de viitor în depistarea precoce a cancerului ovarian.
Abstract – NEW ULTRASOUND TEHNICS, CONTRAST ULTRASOUND, FOR EVALUATING TUMOR NEOVASCULARIY
The performance of ultrasound in mode B are relatively limited in the morphological description of ovarian lesions. On the basis of investigational studies performed in an animal model, it was envisioned that microbubble contrast agents could be used to detect tumor neovascularity.
The evaluation of blood flow by Doppler ultrasound method allows arguments to a malignant disease, but remains insufficient, so ultrasound contrast remains an alternative technique for evaluating tumor neovascularity. Thus using contrast agents can do to differentiate between a malignant and a benign ovarian lesion remaining technical challenges in early detection of ovarian cancer.
