I think according to the books and net. the CT scan is better then US, because..
CT scan is the diagnostic modality of choice because it is more sensitive and accurate in diagnosing an intra-abdominal abscess (90%) than ultrasonography. CT scan also is more effective for defining the precise location, size, degree, and extent of the loculation in relation to other retroperitoneal structures. CT scan also may show renal enlargement; focal parenchymal decreased attenuation; fluid, gas, or both in and around the kidneys; focal thickening of the Gerota fascia; and obliteration of adjacent tissue planes.
The typical appearance of a perinephric abscess on CT scan is that of a soft-tissue mass with a thick wall that may enhance after introducing intravenous contrast material.
Hope that's help

hi..
i think that US is the best choice in this case because julia is
pregnant and CT may cause malformations in the embryo.
