Fig. 8From: Active surveillance of small renal massesComparison of maximum tumor diameter (MTD) in the axial plane of a small renal mass (SRM) with different imaging modalities (arrows). a Sagittal ultrasound (US) view. b Axial contrast-enhanced CT scan and (c) axial contrast-enhanced T1-weighted MR of the same renal lesion demonstrating there are no significant differences between US, CT, and MR with the use of the same plane for measuring MTD (3.33ācm, 3.46ācm, and 3.29ācm, respectively). Note that the differences between different radiological tests are less than 0.2ācmBack to article page
