View larger version (13K): [in a new window]   Fig. 1. —Histogram depicts number of tumors found per patient. Left columns (gray) represent cystoscopy, and right columns (white) represent virtual endoscopy. Findings on conventional cystoscopy revealed that 17 patients had single bladder tumor, five had two tumors, and two had three tumors.

View larger version (16K): [in a new window]   Fig. 2. —Histogram depicts number of tumors found on cystoscopy (gray columns) and virtual endoscopy (white columns) and their diameters. All known tumors of 1 cm and larger were seen on virtual endoscopy. All three tumors not identified on virtual endoscopy were smaller than 1 cm in diameter. Two tumors not discovered on cystoscopy but detected by virtual endoscopy are included in corresponding columns.

View larger version (112K): [in a new window]   Fig. 3A. —62-year-old man with primary urinary bladder cancer. Anteroposterior virtual endoscopic image depicts posterior bladder wall and vesical trigone. The trigone is demarcated by two ureteric orifices (arrowheads) and internal urethral orifice (arrow). Marked prostatic protrusion visible in foreground is consistent with prostatic hypertrophy.

Virtual endoscopic intravesical image of anterior bladder wall (posteroanterior view: field of view, 90°) depicts two papillary tumors (arrowheads) 0.8 and 1.4 cm in diameter at left anterior bladder wall and right ventral dome.

Virtual endoscopic images of four bladder wall diverticula before zooming (A) and after zooming (B) show tumor at neck of one diverticulum (arrow). Tumor diameter is 0.4 cm—one of smallest found in our study.

Virtual endoscopic images of four bladder wall diverticula before zooming (A) and after zooming (B) show tumor at neck of one diverticulum (arrow). Tumor diameter is 0.4 cm—one of smallest found in our study.

View larger version (141K): [in a new window]   Fig. 5A. —64-year-old man with solitary urinary bladder tumor. Conventional cystoscopic image (A) and virtual endoscopic image (B: field of view, 30°) depict tumor 2.3 cm in diameter.

View larger version (156K): [in a new window]   Fig. 5B. —64-year-old man with solitary urinary bladder tumor. Conventional cystoscopic image (A) and virtual endoscopic image (B: field of view, 30°) depict tumor 2.3 cm in diameter.

View larger version (99K): [in a new window]   Fig. 5C. —64-year-old man with solitary urinary bladder tumor. Coronal T2-weighted MR image (C) and virtual endoscopic image with overall view (D, 120°) show tumor's location next to vesical trigone ventrolateral to left ureteric orifice. Internal urethral orifice can be identified in lower mid portion of D.

Coronal T2-weighted MR image (C) and virtual endoscopic image with overall view (D, 120°) show tumor's location next to vesical trigone ventrolateral to left ureteric orifice. Internal urethral orifice can be identified in lower mid portion of D.

View larger version (100K): [in a new window]   Fig. 6A. —60-year-old man with primary urinary bladder cancer. Coronal T2-weighted MR image shows two lesions (arrows) in right and left lower part of bladder in area of vesical trigone.

View larger version (99K): [in a new window]   Fig. 6B. —60-year-old man with primary urinary bladder cancer. Virtual endoscopic image focused on vesical trigone reveals that only one tumor is present (1.4 cm in diameter, arrow). Tumor is located near left ureteric orifice. Structure seen on right side in coronal T2-weighted image (A) is identified on virtual endoscopic image as part of normal vesical trigone and not tumor. Internal urethral orifice can be identified in lower mid portion.
