Figure 6 Image sequence demonstrating coronal cuts on MRI Figure 6 | Images sequence demonstrating coronal cuts on MRI. a,b | Images obtained using T2 and c,d | images obtained using T1 sequences, clearly demonstrating hydronephrosis but distal pathology is not clear. Scan performed for cancer surveillance — differential included metastasis, extrinsic ureteral compression and stones. e–g | CT images showing the hydronephrosis and hydroureter; a distal right ureteral stone is now easily visualized enabling diagnosis and considerably altering this patient's treatment course.
