Although several studies have reported the general imaging features of BCAs (14-17) and MEs (18, 19), only a few have dealt with their enhancement pattern on dynamic CT
and MRI examinations including two-phase CT (16, 20-22).
(17) Patients with a spinal extradural fluid collection (Figure 4) should have a follow-up dynamic CT
According to the company, the Viz CTP offers image processing software to view and analyze functional and dynamic CT
However, dynamic CT
is practically difficult because of the requirements for high spatial resolution and temporal resolution.
Noncontrast enhanced CT revealed a right renal stone and a complicated cyst in the upper pole of her right kidney, which was categorized as a Bosniak type IIF cyst on dynamic CT
, with a maximum diameter of 58 mm (Figure 1).
On the eighth day, an abdominal dynamic CT
scan showed a sausage-like, ring-enhanced right retroperitoneal mass with a diameter of 27 mm, which was distinct from the right ovarian vein (Figure 1).
The first patient, who was a man in his late seventies with an unremarkable previous medical history, presented with isovascular nodule accompanied by slow venous wash-out on abdominal dynamic CT
in the left lobe of liver.
Planning CEUS was performed for poorly conspicuous HCCs (probably identifiable, but not with confidence) or invisible HCCs on B-mode US that were visible with dynamic CT

scanning showed a thin wall with slight contrast, but there was no contrast of the cyst content.
