“…Overall accuracy of tumor staging improved significantly, from 67% to 84% (p<0.01). 5 Métastasés in enlarged or normal-sized lymph, nodes may show early enhancement, equal to that of the primary bladder tumor (Fig. 9); therefore, recognition of métastasés in normal-sized nodes may be possible.…”

“…These very small tumours are usually flat and do not produce focal bladder wall thickening or abnormal enhancement owing to the absence of considerable neovascularisation, as has been hypothesised in studies using other imaging techniques [20]. Our results are slightly worse than those obtained using CT or MRI with contrast agents [18,[21][22][23], or using multidetector CT (MDCT) urography [24][25][26]. In the study by Kim et al [18], using MDCT, the detection rate was 97% for all bladder cancers and 85% for bladder cancers smaller than 1 cm.…”

Objective: To assess the accuracy contrast-enhanced ultrasound (CEUS) in bladder cancer detection using transurethral biopsy in conventional cystoscopy as the reference standard and to determine whether CEUS improves the bladder cancer detection rate of baseline ultrasound. Methods: 43 patients with suspected bladder cancer underwent conventional cystoscopy with transurethral biopsy of the suspicious lesions. 64 bladder cancers were confirmed in 33 out of 43 patients. Baseline ultrasound and CEUS were performed the day before surgery and the accuracy of both techniques for bladder cancer detection and number of detected tumours were analysed and compared with the final diagnosis. Results: CEUS was significantly more accurate than ultrasound in determining presence or absence of bladder cancer: 88.37% vs 72.09%. Seven of eight uncertain baseline ultrasound results were correctly diagnosed using CEUS. CEUS sensitivity was also better than that of baseline ultrasound per number of tumours: 65.62% vs 60.93%. CEUS sensitivity for bladder cancer detection was very high for tumours larger than 5 mm (94.7%) but very low for tumours ,5 mm (20%) and also had a very low negative predictive value (28.57%) in tumours ,5 mm. Conclusion: CEUS provided higher accuracy than baseline ultrasound for bladder cancer detection, being especially useful in non-conclusive baseline ultrasound studies.

“…These images are used to optimize cancer-bladder wall contrast [18]. Bladder cancer involving the mucosa and sub-mucosa often shows an early (about 20 s after contrast injection) and prominent enhancement compared with the uninvolved bladder wall which enhance late, usually 60 s after the contrast injection [13,15,19]. And the image (Figure 1(B)) is a dynamic contrast enhanced image obtaining from the same patient as (Figure 1(A)) in our department, which shows that the tumor presenting an early significant enhancement with an intact bladder muscle wall remaining to be low signal.…”

Urinary bladder cancer is the second most common genitourinary malignancy in Westernized countries. A number of emerging imaging techniques have recently been reported in the literature for use in imaging bladder cancer. While the explicit application of MR imaging in bladder cancer especially in non-distant bladder cancer or bladder cancer localized in pelvic remains uncertain and awaits a thorough evaluation. Therefore, this article aims to make a systematic review of previous literature and provide a complete assessment of the value of MR as an evolving imaging tool in localized urinary bladder cancer application. Studies were conducted by searching the MEDLINE and PubMed databases up to 2012 using both medical subject heading (Mesh) and a free text method like "urinary bladder cancer", "magnetic resonance imaging" or "MRI", "diffusion weighted imaging" or "DWI". About 53 articles were selected and analyzed which were considered to be associated with the objective of this systematic review ( Table 1). Results showed that MRI especially the newer functional imaging technique like DWI may has a great potential role in localized bladder cancer like early detection, staging, evaluation of tumor aggressiveness and therapeutic responsiveness of patients in the assessment of urinary bladder cancer and so forth. Newer MRI has already proceeded promising results in bladder cancer application; and the explicit role of newer MRI in bladder cancer patients still needs further research and awaits to be thoroughly evaluated.
