The average defect size on the immediate postsurgical study was 2.2 × 2.4 mm (ellipsoid area of 4.6 mm2). Two patients had their ETVs close during the studied time (2/34, 6%). All other patients showed an increase in size of the ETV(More)
Aim The conversion of attenuation factors (AF) derived from Hounsfield units to SF for 511 KeV photons can be described using a single bilinear function for different tissues. The use of IV contrast agents may interfere with AF from CT when scans are acquired in the arterial phase. In this study, we investigated if AF derived from CECT when scans are(More)
