Desi majoritatea sistemelor efectueaza toate tipurile de investigatii, au
fost create sisteme dedicate anumitor tipuri de examinari:

          - GAMA VOLUSON dedicata, in special, examinarilor
obstetricale si ginecologice

        - LOGIQ dedicata pentru restul tipurilor de examinari:
abdominala, parti moi, contrast, elastografie

ECOGRAFIA CU SUBSTANTA DE
              CONTRAST
Consta in injectarea intravenoasa a unui agent de contrast

In cazul ecografiei cel mai bun agent de contrast este gazul

Doua generatii de agenti de contrast - cel mai folosit agent de contrast
in Europa este Sonovue. Acesta are doua componente:
        - capsula fosfolipidica
        - continutul gaz - sulfur hexafluorid

ECOGRAFIA CU SUBSTANTA DE
              CONTRAST
 Scopul este de a vizualiza microvascularizatia diferitelor structuri

 Pe baza microvascularizatiei si a modului in care se comporta fata
  de substanta de contrast, se poate realiza o caracterizare
  morfopatologica a acestora

 Societatea Europeana de Ultrasonografie in Medicina si Biologie
  (EFSUMB) a elaborat ghidurile si recomandarile de folosire a
  agentilor de contrast

 Pacienta in varsta de 43 ani  Se descopera o formatiune focala
                                    solida intrahepatica de aproximativ 3
                                    cm, localizata la nivelul sg 4,
                                    subcapsular si deformand caspula
 Investigata anterior ecografic,
                                   Evaluarea Doppler- vascularizatie
  fara patologie cunoscuta
                                    prin artera unica

                                    formatiune benigna-
 Se prezinta pentru efectuarea HNF/Adenom/Hemangiom atipic
  de rutina a ecografiei           Pacienta doreste continuarea
                                    investigatiilor pentru stabilirea
                                    substratului morfopatologic

ELASTOGRAFIA
 Reprezinta metoda prin care se masoara densitatea tesuturilor cu
  ajutorul ultrasunetelor
 Exista 2 metode:
    operator dependenta prin care se aplica de catre examinator
      presiune repetitiva pe zona de interes
    operator independenta prin care aparatul emite singur o unda
      care deformeaza tesuturile
 Evaluarea initiala se face sub forma unei game de culori
 Ulterior se poate face si cuantificarea fata de tesuturile invecinate
  sub forma unui indice




                                                       www.reginamaria.ro

ELASTOGRAFIA

Se poate aplica asupra oricarei structuri in functie de localizarea
acesteia

Fibroscanul reprezinta o varianta a elastografiei

Ca si principiu general, cu cat o structura prezinta o densitate mai
mare si implicit este mai dura, cresc sansele de a fi maligna
