Aquilion prime tsx 303a

Computed tomography pulmonary angiography (CTPA; Aquilion PRIME TSX-303A Toshiba, Tustin, CA, USA), a method of choice serving to assess the pulmonary vessels when PE is suspected, was performed in all experimental pigs after the release of the thrombi from the right femoral veins. Using a maximum intensity projection (MIP) technique the thrombi were visualized and measured with the Toshiba Aquilion PRIME TSX-303A as standard software tool. During the CTPA procedure, the animals were sedated with propofol (Propofol-Lipuro, B. Braun Melsungen AG, 10 mg/kg b.w.).

For the CT scanner at the JSACC, we used a 4 multidetector‐row (MD) CT scanner (Asteion Super4 Edition TSX‐02B/6; Toshiba Medical Systems, Otahara City, Japan) from 2005 to January 2015 and an 80MDCT scanner (Aquilion prime TSX‐303A; Toshiba Medical Systems, Otahara City, Japan) from February 2015 to 2021. Contrast‐enhanced CT of the chest was performed under general anesthesia. The CT scanning and reconstruction parameters used at the JSACC for the 4MDCT scanner were 120 kVp, 120 mA, rotation time = 0.75 seconds, slice thickness = 1‐2 mm, beam pitch = 1.374, reconstruction interval = 1‐2 mm, and a standard algorithm, whereas for the 80MDCT scanner these were 120 kVp, 350 mA, rotation time = 0.5 seconds, slice thickness = 0.5 mm, beam pitch = 1.388, reconstruction interval = 0.5 mm, and a standard algorithm. Iopamidol (Oypalomin; Fuji Pharma) was used as the contrast agent for CT. This contrast agent was administered at a dosage of 2‐2.5 mL/kg (600‐750 mg/kg) for >10 seconds via the cephalic vein, and images were taken 120 seconds after administration.
