Abstract
Consensus regarding which modality is optimal for the
measurement of pancreas cystic lesions (PCLs) was not achieved
although cyst size is important for clinical decisions. This study aimed
to evaluate the properties of endoscopic ultrasonography (EUS) compared
with computed tomography (CT) and magnetic resonance imaging
(MRI) in measuring the size of PCL.
A total of 34 patients who underwent all 3 imaging modalities within
3 months before surgery were evaluated retrospectively. The size
measured by each modality was compared with the pathologic size
as a reference standard using Bland–Altman analysis and intraclass
correlation coefficients (ICCs).
The mean size difference was 1.76mm (ICC 0.86), 7.35mm (ICC
0.95), and 8.65mm (ICC 0.93) in EUS, CT, and MRI. EUS had the
widest range of 95% limits of agreement (LOA) ( 17.54 to þ21.07),
compared with CT ( 6.21 to þ20.91), and MRI ( 6.82 to þ24.12). The
size by EUS tended to be read smaller in tail portion, while those by CT
and MRI did not. When the size was more than 4 cm, the size on EUS
was estimated to be smaller than on pathology (r¼0.492; P¼0.003).
Although 3 modalities showed very good reliability for the size
measurement on PCL compared with corresponding pathologic size,
EUS had the lowest level of agreement, while CT showed the highest
level among the 3 modalities. Therefore, the size estimated by EUS has
to be interpreted with caution, especially when it is located in tail and
relevantly large.
